Examples that remain on the current upstream/dev tree include sys_select (io_mpx/select.rs), the network sendmsg / recvmsg path (net/io.rs), event-device ioctls (pseudofs/dev/event.rs) and the file-lock ioctls (fs/lock.rs). When a concurrent fork(clone_map) re-marks the underlying COW pages read-only between check_region() and the kernel-mode write, the write triggers a #PF (present + WRITE bit set) whose RIP is in kernel text and has no fixup-table entry. The previous handler returned early on !is_accessing_user_memory(), turning this into an unrecoverable panic. Extend handle_page_fault so a kernel-mode fault on a user-space address goes through the regular aspace.handle_page_fault() path (which invokes the COW backend) just like a user-mode write would. Two guards keep the extension safe: 1. Reject fault addresses outside USER_SPACE_BASE..USER_SPACE_END so genuine kernel-text / kernel-stack faults still bubble up unchanged. 2. Bail out if the current thread already holds the aspace lock, which prevents a recursive lock acquisition / deadlock when a fault occurs inside aspace.lock().handle_page_fault() itself.

-`BaseDriverOps` 的接口极小： - -- `device_name()`：提供用于日志、调试和上层识别的设备名。 -- `device_type()`：把实例绑定到统一类别。 -- `irq_num()`：默认为 `None`，只有需要向上暴露 IRQ 号的驱动才覆写。 - -这种设计有两个直接后果： - -1. 各类别 crate 可以在自己的 trait 中追加能力，而不必重复定义名称和类别接口。 -2. 上层聚合层和日志系统可以只依赖 `BaseDriverOps` 做通用处理，而不用知道具体是块设备、网卡还是输入设备。 - -### 1.4 与相邻层的边界 -| 层次 | 负责内容 | 不负责内容 | -| --- | --- | --- | -| `ax-driver-base` | 设备类别、错误模型、最小元信息接口 |

`BlockDriverOps` 或 `NetDriverOps`。 -3. 最终由 `ax-driver` 聚合层把实例包装进 `AxDeviceEnum` 或 `Ax*Device`。 - -也就是说，`ax-driver-base` 只定义“底座接口”，并不规定设备如何初始化、如何被发现、如何被消费。 - -### 2.3 当前实现特征 -- 该 crate 没有 Cargo feature，也没有内部子模块拆分，说明它被刻意维持在最稳定、最少变化的一层。 -- `DevError` 主要覆盖驱动常见失败语义，例如 `Again`、`NoMemory`、`Unsupported`、`BadState` 等，适合 no_std 驱动环境的通用错误归一。 -- `core::fmt::Display` 只为 `DevError` 提供人类可读文本，不承担额外错误上下文聚合。

需要补充跨类别通用的错误语义。 - -如果只是新增块设备、网卡、显示设备或输入设备能力，通常应改对应的类别 crate，而不是这里。 - -### 4.2 修改时必须同步检查的地方 -1. 若新增 `DeviceType` 成员，需要同步检查 `ax-driver::AxDeviceEnum`、`AllDevices`、`prelude.rs` 和上层消费者是否都能识别该类别。 -2. 若调整 `DevError`，需要确认 `ax_driver_virtio::as_dev_err()`、`axdriver_block`、`axdriver_net` 等映射逻辑仍然一致。 -3. 若给 `BaseDriverOps` 增加新方法，会影响所有驱动实现，是高风险接口变更。 - -### 4.3 常见误区 -- 不要把类别专属能力塞进 `BaseDriverOps`。例如 `read_block()`、`flush()`、`read_event()` 都应留在各自类别 trait 中。 -- 不要把设备探测接口放进这里；探测属于 `ax-driver` 或总线/传输适配层的职责。 -- 不要把“设备名可打印”误解为“设备可被系统自动管理”；管理逻辑在上层。 - -## 测试 -### 5.1 当前验证形态 -该 crate 没有单独的 `tests/` 目录。它的正确性主要通过编译期接口一致性和上层集成使用来验证。 - -### 单元测试 -- `DeviceType` 的基础匹配逻辑。 -- `DevError` 的 `Display` 文本。 -- `BaseDriverOps` 默认 `irq_num()` 返回 `None` 的契约。 - -### 集成测试 -- 各类别驱动能否以同一套 `BaseDriverOps` 被 `ax-driver::prelude` 和 `AllDevices` 使用。 -- `DevError` 是否能被 `ax-driver-virtio`、`axdriver_net`、`axdriver_block` 等映射成一致行为。 - -### 5.4 风险点 -- 新增设备类别时，最容易漏掉上层聚合容器和日志路径。 -- 改动 `BaseDriverOps` 是典型的“低层小改动、全栈大影响”风险点。 - -## 跨项目定位 -### ArceOS -这是当前仓库中最主要的直接消费方。ArceOS 通过 `ax-driver` 聚合层把它作为整个驱动体系的公共接口底座。 - -### StarryOS -StarryOS 不是直接围绕 `ax-driver-base` 写业务逻辑，而是通过共享的 `ax-driver`、`ax-display`、`ax-input` 等模块间接复用这套基础契约。 - -### Axvisor -当前仓库里没有看到 Axvisor 直接把 `ax-driver-base` 当作其核心设备管理接口。即便未来在某些宿主兼容路径中复用它，它也只会扮演“共享驱动契约层”，而不是虚拟机设备分发中心。 diff --git

-- 多块读写通过 `as_chunks()` / `as_chunks_mut()` 分块循环完成。 -- 若缓冲区长度不是块大小整数倍，返回 `DevError::InvalidParam`。 - -#### `bcm2835sdhci` -`bcm2835sdhci::SDHCIDriver` 通过 `try_new()` 初始化控制器： - -- 初始化失败直接映射为 `DevError::Io`。 -- 读写要求缓冲区至少覆盖一个块，且需满足 `u32` 对齐要求。 -- 将外部 `SDHCIError` 映射回统一的 `DevError`。 - -### 1.4 与 `ax-driver` 聚合层的接线关系 -在当前仓库中，真正把这些实现接进系统初始化流程的是 `os/arceos/modules/axdriver/src/drivers.rs`： - -- `ramdisk` 通过 `RamDiskDriver::probe_global()` 创建固定大小 16 MiB RAM 盘。 -- `sdmmc` 通过 `SdMmcDriver::new()` 使用 `ax_config::devices::SDMMC_PADDR` 对应寄存器基址。 -- `bcm2835-sdhci` 通过 `SDHCIDriver::try_new()` 接入。 - -需要特别注意一个实现事实：**`axdriver_block` 虽然有 `ahci` feature 和 `ahci` 模块，但当前 `ax-driver::drivers.rs` 并没有把 AHCI 探测逻辑注册进去。** 也就是说，打开 feature 并不等于当前 ArceOS 探测路径就会自动发现 AHCI 设备。 - -### 1.5 与动态平台路径的关系 -在 `platform/axplat-dyn/src/drivers/blk/mod.rs` 中，`rd_block::Block` 会被包装成实现 `BlockDriverOps` 的 `Block`。这说明： - -- `axdriver_block` 的核心价值首先是 trait 契约。 -- 具体实现不一定非要写在本 crate 内，也可以由其它 crate 适配后满足

-- 绝大多数 PCI 相关类型直接从 `virtio_drivers::transport::pci::bus` 再导出。 -- 本 crate 自己真正新增的核心对象只有 `PciRangeAllocator`。 -- 真正的 PCI 枚举、BAR 配置和驱动派发逻辑在 `os/arceos/modules/axdriver/src/bus/pci.rs`。 - -因此它更像是 ArceOS 驱动栈里的“PCI 公共类型与分配辅助层”，而不是独立 PCI 子系统。 - -### 1.2 关键对象 -| 符号 | 作用 | 来源 | -| --- | --- | --- | -| `PciRoot`、`DeviceFunction`、`BarInfo` 等 | 访问 PCI 配置空间和设备信息 | 由 `virtio-drivers` 再导出 | -| `PciRangeAllocator` | 为 BAR 分配 MMIO 地址空间 | 本 crate 自定义 | -| `PciError`、`Command`、`Status` | PCI 操作辅助类型 | 由 `virtio-drivers` 再导出 | - -### 1.3 `PciRangeAllocator` 的作用 -`PciRangeAllocator` 只做一件事：从一段 MMIO 地址窗口中分配满足对齐要求的连续区域。 - -其特点是： - -- `new(base, size)` 以一段物理窗口初始化分配器。 -- `alloc(size)` 要求 `size` 必须是 2 的幂。 -- 返回地址会自动按 `size` 对齐。 -- 若空间不足或参数不合法，返回 `None`。 - -它本质上是一个顺序递增分配器，适合 BAR 窗口这种“启动期一次性分配、运行期不回收”的场景。 - -### 1.4 在 `ax-driver` 中的真实调用方式 -在 `os/arceos/modules/axdriver/src/bus/pci.rs` 里，PCI 探测主线如下： - -1. 用 `PciRoot::new(..., Cam::Ecam)` 打开 ECAM。 -2. 从 `ax_config::devices::PCI_RANGES` 取出 32 位 MMIO 窗口，创建 `PciRangeAllocator`。 -3. 枚举每个 bus 上的设备。 -4. 对 BAR 逐个调用 `config_pci_device()`： - - 若 BAR 未分配地址，调用 `PciRangeAllocator::alloc()` 分配。 - - 再把 `IO_SPACE`、`MEMORY_SPACE`、`BUS_MASTER` 打开。 -5. 最后再把设备交给 `Driver::probe_pci()` 做类别识别和具体驱动创建。 - -这说明： - -- `ax-driver-pci` 负责的是“访问和分配”。 -- `ax-driver` 才负责“枚举和派发”。 - -### 1.5 与 VirtIO 路径的关系 -`ax_driver_virtio::probe_pci_device()` 和 `os/arceos/modules/axdriver/src/virtio.rs` 会继续基于 `PciRoot`、`DeviceFunction`、`DeviceFunctionInfo` 做 VirtIO PCI 设备识别。因此 `ax-driver-pci` 也是 VirtIO PCI 探测路径的底层依赖。 - -### 1.6 边界澄清 -最关键的边界是：**`ax-driver-pci` 是 PCI 总线访问辅助层，不是通用驱动聚合层，也不是完整的 PCI 设备管理子系统。** - -## 核心功能 -### 功能概览 -- 统一提供 PCI 配置空间访问相关类型。 -- 为 BAR 资源分配提供最小分配器 `PciRangeAllocator`。 -- 为上层 `ax-driver` 的 PCI 枚举和 VirtIO PCI 探测提供公共底座。 - -### 2.2 当前实现特征 -- crate 自身没有 Cargo feature，也没有内部子模块拆分。 -- 本地逻辑极少，绝大部分能力直接复用 `virtio-drivers`。 -- 设计上故意不引入设备类别概念，从而保持总线层的中立性。 - -### 2.3 不负责的事情 -- 不负责扫描 bus 范围和设备树。 -- 不负责 IRQ 路由。 -- 不负责设备类别识别。 -- 不负责 DMA、IOMMU 或驱动生命周期管理。 - -## 依赖关系 -### 直接依赖 -| 依赖 | 作用 | -| --- | --- | -| `virtio-drivers` | 提供 PCI bus 访问类型和实现 | - -### 主要消费者 -- `os/arceos/modules/axdriver/src/bus/pci.rs` -- `os/arceos/modules/axdriver/src/virtio.rs` - -### 3.3 分层关系总结 -- 向下：依赖 `virtio-drivers` 的 PCI bus 实现。 -- 向上：服务 `ax-driver` 的 PCI 探测与 VirtIO PCI 路径。 -- 横向：保持对设备类别中立，不直接依赖 `axdriver_block`、`axdriver_net` 等类别 crate。 - -## 开发指南 -### 4.1 何时应改这里 -适合修改 `ax-driver-pci` 的场景包括： - -- 需要给所有 PCI 设备路径新增通用辅助逻辑。 -- 需要补充 BAR 分配或 PCI 配置访问相关能力。 -- 需要统一仓库内对 `virtio-drivers` PCI bus API 的适配点。 - -如果只是新增某类 PCI 设备驱动，通常应修改 `ax-driver` 或对应设备 crate，而不是这里。 - -### 4.2 修改时要同步检查的地方 -1. `os/arceos/modules/axdriver/src/bus/pci.rs` 的枚举和 BAR 配置逻辑。 -2. `ax_config::devices::PCI_ECAM_BASE`、`PCI_RANGES`、`PCI_BUS_END` 等平台配置。 -3. `ax-driver-virtio` 的 PCI 探测路径是否仍与类型再导出保持一致。 - -### 4.3 常见坑 -- 不要把 `PciRangeAllocator` 当成通用内存分配器；它只适合启动期 BAR 窗口。 -- 不要在这里引入按设备类别分支的逻辑；那会污染总线层边界。 -- 升级 `virtio-drivers` 时，要注意其 PCI 类型 API 变更可能直接影响本 crate 的对外接口。 - -## 测试 -### 测试覆盖 -该 crate 没有独立测试目录，当前有效验证主要来自： - -- QEMU/真实平台上的 PCI 枚举。 -- BAR 地址自动分配。 -- VirtIO PCI 和 ixgbe PCI 设备是否能被后续驱动正确接管。 - -### 单元测试 -- `PciRangeAllocator::alloc()` 的对齐、越界和非法参数处理。 -- 不同 BAR 大小组合下的顺序分配结果。 - -### 集成测试 -- `PCI_ECAM_BASE` 有效性与总线枚举。 -- 未初始化 BAR 的自动分配与命令寄存器启用。 -- `virtio-net`、`virtio-blk`、`ixgbe` 等不同 PCI 设备的后续探测。 - -### 5.4 风险点 -- BAR 分配错误会直接导致后续驱动映射错误，通常很难在更上层快速定位。 -- 若把设备类别识别逻辑下沉到这里，会破坏整个驱动栈的层次边界。 - -## 跨项目定位 -### ArceOS -ArceOS 是当前仓库里唯一明确的直接主线消费者。`ax-driver` 的 PCI 探测路径完全建立在本 crate 暴露的类型和分配器之上。 - -### StarryOS -StarryOS 若复用 ArceOS 底层驱动栈，会间接依赖本 crate；但当前仓库中没有看到它作为 StarryOS 独立 PCI 子系统直接存在。 - -### Axvisor -当前仓库里没有看到 Axvisor 直接依赖 `ax-driver-pci`。它不是 Axvisor 的宿主 PCI 管理核心，也不是虚拟 PCI 设备框架。 diff --git a/docs/docs/components/crates/ax-driver-virtio.md b/docs/docs/components/crates/ax-driver-virtio.md deleted file mode 100644 index 43615483a4..0000000000 --- a/docs/docs/components/crates/ax-driver-virtio.md +++ /dev/null @@ -1,179 +0,0 @@ -# `ax-driver-virtio` -

-### Axvisor -Axvisor 并不把 `ax-driver` 当作虚拟化控制核心，但会在宿主侧块设备等兼容路径中借用 ArceOS 生态的设备 trait 与对象模型。因此 `ax-driver` 在 Axvisor 中扮演的是“宿主设备兼容层的基础设施”，而不是“VMM 策略层”。 +涉及 ArceOS 运行路径时，继续跑对应 `cargo xtask arceos test qemu ...` 用例。 diff --git a/docs/docs/components/crates/ax-feat.md b/docs/docs/components/crates/ax-feat.md index 3c7d44211c..2d0f5cfa98 100644 --- a/docs/docs/components/crates/ax-feat.md +++ b/docs/docs/components/crates/ax-feat.md @@ -72,10 +72,10 @@ graph LR -

All detected devices are composed into a large struct [`AllDevices`] -//! and returned by the [`init_drivers`] function. The upperlayer subsystems -//! (e.g., the network stack) may unpack the struct to get the specified device -//! driver they want. -//! -//! For each device category (i.e., net, block, display, etc.), an unified type -//! is used to represent all devices in that category. Currently, there are 3 -//! categories: [`AxNetDevice`], [`AxBlockDevice`], and [`AxDisplayDevice`]. -//! -//! # Concepts -//! -//! This crate supports two device models depending on the `dyn` feature: -//! -//! - **Static**: The type of all devices is static, it is determined at compile -//! time by corresponding cargo features. For example, [`AxNetDevice`] will be -//! an alias of [`VirtioNetDev`] if the `virtio-net` feature is enabled. This -//! model provides the best performance as it avoids dynamic dispatch. But on -//! limitation, only one device instance is supported for each device category. -//! - **Dynamic**: All device instance is using [trait objects] and wrapped in a -//! `Box`. For example, [`AxNetDevice`] will be [`Box`]. -//! When call a method provided by the device, it uses [dynamic dispatch][dyn] -//! that may introduce a little overhead. But on the other hand, it is more -//! flexible, multiple instances of each device category are supported. -//! -//! # Supported Devices -//! -//! | Device Category | Cargo Feature | Description | -//! |-|-|-| -//! | Block | `ramdisk` | A RAM disk that stores data in a vector | -//! | Block | `virtio-blk` | VirtIO block device | -//! | Network | `virtio-net` | VirtIO network device | -//! | Display | `virtio-gpu` | VirtIO graphics device | -//! -//! # Other Cargo Features -//! -//! - `dyn`: use the dynamic device model (see above). -//! - `bus-mmio`: use device tree to probe all MMIO devices. -//! - `bus-pci`: use PCI bus to probe all PCI devices. This feature is -//! enabled by default. -//! - `virtio`: use VirtIO devices. This is enabled if any of `virtio-blk`, -//! `virtio-net` or `virtio-gpu` is enabled. -//! - `net`: use network devices. This is enabled if any feature of network -//! devices is selected. If this feature is enabled without any network device -//! features, a dummy struct is used for [`AxNetDevice`]. -//! - `block`: use block storage devices.

2026 12:21:48 +0800 Subject: [PATCH 15/71] fix(starry-kernel): close EPOLLET race window and NoEvent busy-loop (#910) Two related bugs in the EPOLLET delivery path broke event-driven runtimes on Tokio-style applications (jcode TUI, reqwest, etc.). 1. NoEvent path busy-loop on connected TCP sockets When InterestWaker fires but consume() reports no matching events (a spurious wake, e.g. a shared PollSet wake on an interest registered only for EPOLLIN while the underlying socket has EPOLLOUT-ready), the old code called check_and_register_waker(). That helper polls the file and immediately calls waker.wake_by_ref() if file.poll() is non-empty. Connected TCP sockets always advertise EPOLLOUT, so every spurious NoEvent reissued the waker and re-queued the interest: NoEvent -> check_and_register_waker -> EPOLLOUT present -> wake_by_ref -> re-queued -> NoEvent -> ... The ready_queue filled with phantom entries and epoll_wait returned maxevents (up to 1024) of duplicate notifications, which kept tokio spinning without ever confirming the TCP handshake. Fix: use register_waker_only on the NoEvent path so the interest is re-armed and only fires on a genuine state transition, matching the EPOLLET contract. 2. EventAndRemove race window between mark_not_in_queue() and re-arm After delivering an EPOLLET event, mark_not_in_queue() clears the in-queue flag and then register_waker_only() installs a new InterestWaker. The previous InterestWaker had already been consumed by the wake that delivered the first chunk, leaving the underlying PollSet empty in the gap between the two calls. If the peer writes a second chunk inside that window, poll_update.wake() hits the empty PollSet and the notification is silently dropped. The fresh waker is then installed only after the data has already arrived; no further write occurs and EPOLLET never fires again. The visible symptom was jcode TUI hanging after the first AI response chunk. Fix: after register_waker_only(), re-check the file for IN/RDHUP/HUP events. If data is already present, CAS the in-queue flag back to true and re-push the interest onto the ready queue directly (without going through waker.wake_by_ref(), which would reintroduce the bug-1 busy-loop). EPOLLOUT is intentionally excluded: writable sockets are normally always OUT-ready and a check there would spin. Add bug-epollet-second-chunk regression test covering both paths: an idle EPOLLET interest must not return phantom events from an always-OUT socket, and 32 back-to-back chunk-A/chunk-B rounds must each be reported by their own epoll_wait() call.

charset=UTF-8 Content-Transfer-Encoding: 8bit ## 问题 x86-64 上,依赖 raw ABI 偏移读写信号上下文的运行时会损坏寄存器。最典型是 Go 的异步抢占(SIGURG):其 signal handler 读写 `uc_mcontext.gregs[REG_RSP/REG_RIP]` 并指望 `rt_sigreturn` 按这些写回恢复;在 StarryOS 上 `RSP` 被错位 8 字节、载入相邻的非指针字节 → `unsafe.Slice: len out of range` panic。 ## 根因 `MContext`(对应 Linux `struct sigcontext` / `mcontext_t`)被标注 `#[repr(C, align(16))]`。但 Linux 的 `mcontext_t` 是**自然 8 字节对齐**,且在 `ucontext_t` 里 `uc_mcontext` 位于结构体**中部**(偏移 40,紧随 `uc_flags`/`uc_link`/`uc_stack`)。强制 16 对齐会在 `uc_stack`(@16..40)之后插入 8 字节填充,把 `uc_mcontext` 推到偏移 48 → 其内每个通用寄存器(RSP@160、RIP@168)、fpregs 指针、以及随后的 `uc_sigmask` 全部相对 Linux ABI 偏移 8 字节。Go 按裸偏移访问即错位。 ## 修复 - `MContext`:`#[repr(C, align(16))]` → `#[repr(C)]`(恢复自然 8 对齐 → `uc_mcontext`@40)。 - `UContext`:`#[repr(C)]` → `#[repr(C, align(16))]`。信号帧本身要求落在用户栈 16 对齐处(handler 入口须 `RSP%16==8`);该对齐改由**外层** `UContext` 提供,既保帧对齐、又不再扰动 `uc_mcontext` 的偏移。 - 新增编译期 `const _` 断言锁定 `offset_of!(UContext, mcontext)==40 && offset_of!(UContext, sigmask)==296`,作为 ABI 回归守卫(偏移再被改错即编译失败)。 仅改 `components/starry-signal/src/arch/x86_64.rs`,不触其它 arch/调用方。 ## 对照 Linux(验证) Linux/musl x86-64 `ucontext_t`:`uc_flags`@0、`uc_link`@8、`uc_stack`@16、`uc_mcontext`@40、`uc_sigmask`@296(`struct sigcontext` 256 字节)。本修后 StarryOS 偏移与之逐一吻合(const-assert 编译期证实)。Go runtime 在 host Linux 正常异步抢占即依赖此布局。 ## 测试 `cargo xtask starry build --arch x86_64` 通过(含上述 const-assert);openjdk17(信号密集:GC safepoint/SIGSEGV null-check)x86_64 实测无回归。 Signed-off-by: Leo Cheng --- components/starry-signal/src/arch/x86_64.rs | 29 +++++++++++++++++++-- 1 file changed, 27 insertions(+), 2 deletions(-) diff --git a/components/starry-signal/src/arch/x86_64.rs b/components/starry-signal/src/arch/x86_64.rs index 6bc32e2000..688f794f92 100644 --- a/components/starry-signal/src/arch/x86_64.rs +++ b/components/starry-signal/src/arch/x86_64.rs @@ -16,7 +16,18 @@ signal_trampoline: " );

charset=UTF-8 Content-Transfer-Encoding: 8bit ## 问题 在 origin/dev 上,`check_signals` 把 `SignalOSAction::Stop` 处理成 `do_exit(1, true)`:进程收到 SIGSTOP/SIGTSTP/SIGTTIN/SIGTTOU 时不是被挂起,而是被直接退出(杀死)。`SignalOSAction::Continue` 则是空实现,SIGCONT 不做任何事。父进程的 `waitpid(WUNTRACED/WCONTINUED)` 也无从得知子进程的停止/继续。这破坏了 shell 作业控制、`killall5 -STOP/-CONT` 以及 busybox 等依赖作业控制的工具。 ## 根因 缺少真正的作业控制状态机:没有"已停止"标志,没有让停止线程在内核里挂起、等待 SIGCONT(或 SIGKILL)唤醒的机制,也没有把停止/继续状态报告给父进程 `waitpid` 的通道。 ## 修复 - `task/mod.rs`:新增 `enum JobStatus {Stopped(Signo), Continued}` 与受单锁保护的 `struct JobControl {stopped, status, continue_generation}`,作为 `ProcessData` 的字段;并新增 `cont_event: Arc`。配套方法:`is_job_stopped` / `set_job_stopped` / `continue_generation` / `set_job_continued`(唤醒 cont_event) / `clear_job_stop_for_kill` / `cont_event` / `peek_job_status_if` / `take_job_status_if`。 - `task/signal.rs`:`SignalOSAction::Stop` 改为调用 `do_job_stop(thr, signo)` —— 记录停止、向父进程发 SIGCHLD(CLD_STOPPED)、然后 `block_on(poll_fn(...))` 在 cont_event 上挂起(非 interruptible:普通信号不得唤醒已停止进程,只有 continue/kill 才清除停止标志)。`send_signal_to_process` 在发送时处理 SIGCONT(丢弃挂起停止、置 continued、报告 CLD_CONTINUED)与 SIGKILL(强制清除停止以便被杀死)。 - `syscall/task/wait.rs`:`sys_waitpid` 在僵尸回收之外,按 `WUNTRACED`/`WCONTINUED` 经 `peek/take_job_status_if` 报告停止/继续状态,编码为 `(signo<<8)|0x7f`(W_STOPCODE)与 `0xffff`。 为不修改 `starry-signal`(本 PR 仅触及上述三个内核文件),用 `continue_generation` 计数关闭 "STOP 后紧接 CONT" 竞态:停止前快照该计数,若期间有 SIGCONT 递增了它,`set_job_stopped` 返回 false 从而不挂起,等价于上游参考实现里在发送端 `discard_pending` 的效果。 ## 对照 Linux(验证) - SIGSTOP/SIGTSTP/SIGTTIN/SIGTTOU 挂起进程而非退出;SIGCONT 恢复;SIGKILL 即使对已停止进程也能终止。 - `waitpid(WUNTRACED)` 报告 `WIFSTOPPED` 且 `WSTOPSIG == 停止信号`;`waitpid(WCONTINUED)` 报告 `WIFCONTINUED`;状态字编码与 Linux 一致(停止 `(signo<<8)|0x7f`,继续 `0xffff`)。 - 父进程在子进程停止/继续时收到 SIGCHLD(CLD_STOPPED / CLD_CONTINUED)。 ## 测试 新增 `test-suit/starryos/normal/qemu-smp1/test-job-control-stop`(四架构 toml + C 测例):fork 一个忙等子进程,父进程 `kill(SIGSTOP)` → `waitpid(WUNTRACED)` 期望 `WIFSTOPPED`,确认子进程未退出且仍存在;`kill(SIGCONT)` → `waitpid(WCONTINUED)` 期望 `WIFCONTINUED`;`kill(SIGKILL)` 回收,期望 `WIFSIGNALED && WTERMSIG==SIGKILL`。在 starry x86_64(smp=1)实跑:15/15 断言通过,success 模式匹配。`cargo xtask starry build --arch x86_64` 与 `cargo fmt --all -- --check` 均通过。 Signed-off-by: Leo Cheng --- os/StarryOS/kernel/src/syscall/task/wait.rs | 37 ++++- os/StarryOS/kernel/src/task/mod.rs | 149 ++++++++++++++++++ os/StarryOS/kernel/src/task/signal.rs | 100 +++++++++++- .../test-job-control-stop/c/CMakeLists.txt | 16 ++ .../test-job-control-stop/c/src/main.c | 81 ++++++++++ .../c/src/test_framework.h | 65 ++++++++ .../test-job-control-stop/qemu-aarch64.toml | 14 ++ .../qemu-loongarch64.toml | 17 ++ .../test-job-control-stop/qemu-riscv64.toml | 14 ++ .../test-job-control-stop/qemu-x86_64.toml | 14 ++ 10 files changed, 499 insertions(+), 8 deletions(-) create mode 100644 test-suit/starryos/normal/qemu-smp1/test-job-control-stop/c/CMakeLists.txt create mode 100644 test-suit/starryos/normal/qemu-smp1/test-job-control-stop/c/src/main.c create mode 100644 test-suit/starryos/normal/qemu-smp1/test-job-control-stop/c/src/test_framework.h create mode 100644 test-suit/starryos/normal/qemu-smp1/test-job-control-stop/qemu-aarch64.toml create mode 100644 test-suit/starryos/normal/qemu-smp1/test-job-control-stop/qemu-loongarch64.toml create mode 100644 test-suit/starryos/normal/qemu-smp1/test-job-control-stop/qemu-riscv64.toml create mode 100644 test-suit/starryos/normal/qemu-smp1/test-job-control-stop/qemu-x86_64.toml diff --git a/os/StarryOS/kernel/src/syscall/task/wait.rs b/os/StarryOS/kernel/src/syscall/task/wait.rs index 86c3b1a45f..003cf1751c 100644 --- a/os/StarryOS/kernel/src/syscall/task/wait.rs +++ b/os/StarryOS/kernel/src/syscall/task/wait.rs @@ -15,7 +15,8 @@ use starry_signal::SignalInfo;

<34859362+ZR233@users.noreply.github.com> Date: Mon, 25 May 2026 15:22:08 +0800 Subject: [PATCH 26/71] refactor(dma-api): split coherent and streaming DMA APIs (#932) * Refactor DMA API usage across various drivers - Updated DMA allocation and deallocation methods to use ContiguousBuffer and CoherentArray types for better memory management. - Replaced deprecated DArray and DBuff types with their new counterparts in the rd-block, net, and usb drivers. - Enhanced memory synchronization methods to ensure proper data handling between CPU and device. - Improved error handling in DMA mapping functions to accommodate new constraints and layout requirements. - Adjusted driver implementations to align with the updated DMA API, ensuring compatibility and performance improvements. * Refactor DMA API for improved coherence and memory management - Updated `CoherentBox` and `ContiguousBox` to use `DmaAllocation` instead of `DCommon` for better memory handling. - Renamed methods in `CoherentBox` and `ContiguousBox` from `as_buff_mut` to `as_bytes_mut` for clarity. - Changed `DmaMapHandle` to use `bounce_ptr` instead of `map_alloc_virt` to better reflect its purpose. - Introduced a new module `op` to handle architecture-specific DMA operations, with aarch64 implementation for cache operations. - Updated `DeviceDma` to use the new `DmaOp` trait for DMA operations, replacing previous OSAL references. - Refactored buffer pool creation methods to use `contiguous_buffer_pool` instead of `new_pool` for consistency. - Removed deprecated code and comments related to previous memory allocation strategies. - Updated tests and driver implementations to align with the new API structure and naming conventions. --- components/axklib/src/dma.rs | 180 ++--

Streaming mappings may use a fast path +when the original buffer already satisfies the constraints; otherwise they +should allocate an in-mask bounce buffer. -### 1. 实现 `DmaOp` trait +## Backend Contract -首先需要为你的平台实现 `DmaOp` trait，提供底层 DMA 操作支持： +Implement `DmaOp` once for the platform: ```rust,ignore -use dma_api::{DmaOp, DmaDirection, DmaHandle, DmaError}; -use core::{alloc::Layout, ptr::NonNull, num::NonZeroUsize}; +use core::{alloc::Layout, num::NonZeroUsize, ptr::NonNull}; +use dma_api::{ + DmaAllocHandle, DmaConstraints, DmaDirection, DmaError, DmaMapHandle, DmaOp, +}; -struct MyDmaImpl; +struct MyDma; -impl DmaOp for MyDmaImpl { +impl DmaOp for MyDma { fn page_size(&self) -> usize { - 4096 // 返回系统页大小 + 4096 } - unsafe fn map_single( + unsafe fn alloc_contiguous( &self, - dma_mask: u64, - addr: NonNull, - size: NonZeroUsize, - align: usize, - direction: DmaDirection, - ) -> Result { - // 实现虚拟地址到 DMA 地址的映射 - // 返回 DmaHandle - todo!() + constraints: DmaConstraints, + layout: Layout, + ) -> Option { + todo!("allocate normal mapped, device-visible contiguous DMA memory") } - unsafe fn unmap_single(&self, handle: DmaHandle) { - // 解除 DMA 映射 - todo!() + unsafe fn dealloc_contiguous(&self, handle: DmaAllocHandle) { + todo!("free alloc_contiguous memory") } unsafe fn alloc_coherent( &self, - dma_mask: u64, + constraints: DmaConstraints, layout: Layout, - ) -> Option { - // 分配 DMA 一致性内存 - todo!() + ) -> Option { + todo!("allocate the same constrained memory and apply coherent policy") } - unsafe fn dealloc_coherent(&self, handle: DmaHandle) { - // 释放 DMA 内存 - todo!() + unsafe fn dealloc_coherent(&self, handle: DmaAllocHandle) { + todo!("restore mapping policy and free alloc_coherent memory") } -} -``` - -### 2. 选择合适的 DMA 容器 - -根据你的使用场景选择： - -| 需求 | 推荐容器 | 特点 | -|------|---------|------| -| 需要数组类型的 DMA 缓冲区 | `DArray` | 自动缓存同步，固定大小 | -| 需要单个结构体的 DMA 缓冲区 | `DBox` | 自动缓存同步，单个值 | -| 映射现有缓冲区用于 DMA | `SArrayPtr` | 手动缓存同步，单个连续内存区域映射 | - ---- - -## 核心概念 - -### DMA 传输方向 (`DmaDirection`) - -DMA 操作有三种方向，决定了缓存同步的行为： - -```rust,ignore -pub enum DmaDirection { - ToDevice, // CPU → 设备：CPU 写数据，设备读 - FromDevice, // 设备 → CPU：设备写数据，CPU 读 - Bidirectional, // 双向：CPU 和设备都可能读写 -} -``` - -**选择指南**： -- **ToDevice**: 用于发送数据到设备（如网卡发送缓冲区） -- **FromDevice**: 用于接收设备数据（如网卡接收缓冲区） -- **Bidirectional**: 用于双向通信（如驱动程序与设备共享内存） - -### 缓存同步 - -DMA 操作需要处理 CPU 缓存和内存之间的数据一致性： - -| 操作 | ToDevice | FromDevice | Bidirectional | -|------|----------|------------|---------------| -| **写数据前** (`confirm_write`) | ✅ 刷新缓存 | ❌ 无操作 | ✅ 刷新缓存 | -| **读数据前** (`prepare_read`) | ❌ 无操作 | ✅ 使缓存失效 | ✅ 使缓存失效 | - -**自动同步 vs 手动同步**： -- `DArray` 和 `DBox`：每次访问（`read`/`set`/`write`/`modify`）**自动**同步对应元素的缓存 -- `SingleMap`：**不自动**同步，用户必须手动调用 `prepare_read_all()` 和 `confirm_write_all()` - -### DMA 地址掩码 (`dma_mask`) - -`dma_mask` 指定设备可寻址的地址范围： - -- `0xFFFFFFFF` (32 位设备，最多 4GB) -- `0xFFFFFFFFFFFFFFFF` (64 位设备，全地址空间) -- 其他值根据设备硬件限制 - ---- - -## 使用场景指南 - -### 场景 1: DMA 数组缓冲区 - -**用途**：需要固定大小的数组类型 DMA 缓冲区 - -**推荐**：`DArray` - -**特点**： -- ✅ 自动缓存同步（每次 `read`/`set` 时） -- ✅ 固定大小，随机访问 -- ✅ 类型安全 - -**示例**： -```rust,ignore,ignore -let device = DeviceDma::new(0xFFFFFFFF, &DMA_IMPL); - -// 创建 100 个 u32 的 DMA 数组 -let mut dma_array = device.array_zero_with_align::(100, 64, DmaDirection::FromDevice) - .expect("Failed to allocate"); - -dma_array.set(0, 0x12345678); // 写入（自动刷新缓存） -let value = dma_array.read(0); // 读取（自动失效缓存） - -let dma_addr = dma_array.dma_addr(); // 获取 DMA 地址给硬件 -``` - -**适用场景**： -- 网卡数据包缓冲区 -- 音频采样缓冲区 -- 图像帧缓冲区 - ---- - -### 场景 2: DMA 单值容器 - -**用途**：需要单个结构体的 DMA 缓冲区 - -**推荐**：`DBox` - -**特点**： -- ✅ 自动缓存同步（每次 `read`/`write`/`modify` 时） -- ✅ 适合配置寄存器、描述符等 -- ✅ 类型安全 - -**示例**： -```rust,ignore,ignore -#[derive(Default)] -struct Descriptor { - addr: u64, - length: u32, - flags: u32, -} - -let mut dma_desc = device.box_zero_with_align::(64, DmaDirection::ToDevice) - .expect("Failed to allocate"); - -dma_desc.modify(|d| d.length = 4096); // 修改（自动刷新缓存） -let desc = dma_desc.read(); // 读取（自动失效缓存） -``` - -**适用场景**： -- DMA 描述符 -- 设备配置结构 -- 状态寄存器 - ---- - -### 场景 3: 映射现有缓冲区 - -**用途**：将已存在的缓冲区映射用于 DMA - -**推荐**：`SingleMap` -**特点**： -- ⚠️ **手动**缓存同步 -- ✅ 临时映射，RAII 自动解映射 -- ✅ 适用于栈分配或静态缓冲区 - -**示例**： -```rust,ignore,ignore -let mut buffer = [0u8; 4096]; - -// 映射现有缓冲区 -let mapping = device.map_single_array(&buffer, 64, DmaDirection::ToDevice) - .expect("Mapping failed"); - -// ⚠️ 重要：使用前必须手动同步缓存 -mapping.confirm_write_all(); // 将 CPU 数据刷到内存 -// ...

registration (#937) * fix(ax-driver): remove CVSD driver references and update dependencies * fix(lib): unify target architecture checks for module imports * Refactor static device registration and probing in various platforms - Updated the static device registration mechanism to use the new `rdrive::module_driver!` macro, simplifying the driver implementation across multiple platforms (axplat-loongarch64-qemu-virt, axplat-riscv64-qemu-virt, axplat-x86-pc, etc.). - Removed the `DriversIf` interface and associated static device descriptors, transitioning to a more streamlined approach that directly registers devices during probing. - Enhanced the PCI ECAM registration process by integrating legacy IRQ routes and memory mapping directly within the probe functions. - Adjusted Cargo.toml files to include necessary dependencies and features for `ax-driver` and `axklib`. - Cleaned up unused code and comments related to static device descriptors in platforms that do not require them (e.g., riscv64-visionfive2). - Updated documentation to reflect changes in the static probing mechanism and the removal of the `StaticDeviceDesc` structure. * Refactor driver registration and update dependencies - Removed `rdrive` dependency from multiple Cargo.toml files and replaced it with `ax_driver`. - Introduced `ax_driver::model_register!` macro in place of `rdrive::module_driver!` across various driver implementations. - Added `rdrive-macros` as a new dependency in Cargo.toml files where applicable. - Updated the Cargo.lock file to reflect the changes in dependencies. - Created a new test file to validate the usability of the `model_register!` macro. * fix(ax-plat-loongarch64-qemu-virt): select ECAM MMIO mapping by paging * fix(ax-plat): skip inactive static bus probes --- Cargo.lock | 38 ++-- .../axplat_crates/axplat/src/drivers.rs | 19 -- components/axplat_crates/axplat/src/lib.rs | 1 - .../axplat-aarch64-bsta1000b/Cargo.toml | 1 -

charset=UTF-8 Content-Transfer-Encoding: 8bit Three related improvements to the ethernet ARP path that together remove the silent-drop and long-stall failure modes seen when applications fan out many concurrent TCP connections through a gateway (browsers, HTTP clients, AI/cloud CLIs like jcode). 1. ETHERNET_MAX_PENDING_PACKETS too small (32 -> 128) Applications opening 10-20 concurrent TCP connections at startup queue each first SYN in the ARP-pending buffer while the gateway MAC is being resolved. 32 slots (~48 KiB) can be exhausted during a real fan-out (tokio reactor flushes a batch of futures with their SYNs at once); the excess SYNs are silently dropped at the link layer and only recover when smoltcp's 1 s TCP retransmit timer rebuilds them through the now-warm neighbor cache, adding a visible 1 s startup stall. 128 slots (~189 KiB) absorbs the burst while keeping the boot-time heap footprint small enough for the 128 MiB QEMU defaults used by the test rigs (raising to 256 was enough to push later mount-heavy syscall tests past the heap-growth limit on riscv64-virt and trigger a StoreFault). 2. NEIGHBOR_TTL too short (60 s -> 300 s) When a streaming response takes longer than 60 s to begin flowing (cold-start + network latency), the cached gateway entry expires exactly as the response begins. The resulting burst of outbound TCP ACKs all re-enter the pending queue at once, overflowing it again and producing the same silent drop. 300 s matches the Linux unicast neighbour default and removes this class of failure. 3. ARP-reply drain stopped at the queue head When an ARP reply arrived the old drain only peeked at the head of the pending queue and stopped as soon as the head's next-hop did not match the just-resolved address. Entries for other already-resolved next-hops queued behind an unresolvable one were permanently blocked (a textbook head-of-line failure). Replace the peek loop with a full pass: dequeue every entry, immediately send the ones whose next-hop is resolved, re-queue the rest in their original order (and re-issue ARP for entries whose neighbour has expired). `kept` is pre-sized to ETHERNET_MAX_PENDING_PACKETS so the drain does not pay heap-realloc cost while servicing an ARP IRQ. This is a defensive correctness fix. In the current ax-net-ng static IP setup the only routing rule is `0.0.0.0/0 via gateway`, so every destination resolves to the same next-hop and the HoL window never opens; the fix matters as soon as a per-subnet on-link rule (already present on the DHCP path) is added on the static path or when a host route via a different next-hop is introduced. Validation * cargo fmt + cargo xtask clippy --package ax-net-ng pass cleanly. * Functional impact validated end-to-end by running jcode (a Tokio / reqwest TUI) on this branch; the previous ~1 s startup stall from the dropped-SYN burst is gone and long streaming responses no longer hit the 60 s TTL re-arming window. Regression test An earlier version of this commit added bug-arp-hol-drain under the bugfix suite, but on closer review the test did not in fact catch either bug: * The capacity-overflow path is not reproducible from sequential userspace syscalls under QEMU SLIRP, because every connect() runs poll_interfaces() which receives the ARP reply and drains the buffer between syscalls. Toggling the constant between 32 and 128 produced identical "64/64 completed in tens of ms" runs, and a 200-connection burst against a 32-slot buffer still completed without any "buffer full" warning. * The HoL drain path cannot be triggered through static-IP routing either, because the only routing rule installed on that path is `0.0.0.0/0 via gateway`, so every connect — even to an unresolvable on-link IP — ends up with next_hop=gateway and the queue only ever holds entries for a single next-hop. Reverting the drain to the buggy peek-and-break still passed the test (confirmed by a kernel-log instrumentation run that showed only ENQUEUE next_hop=10.0.2.2 events). Adding a test that passes equally on the buggy and fixed code is worse than no test, so the file is dropped. A meaningful synthetic regression for these two paths would need either a multi-next-hop routing topology or a way to bypass the per-syscall drain, both of which are out of scope for this change.

AxWaker::wake_by_ref calls unblock_task with resched=true The previous resched=false meant any future woken by an interrupt or another task only became runnable after the currently running task reached its next voluntary yield point. With the default 10 ms timer tick, the visible latency on a two-hop wake (interrupt -> tty reader -> TUI consumer) was up to 20 ms before the consumer started running. Passing resched=true triggers set_preempt_pending() inside unblock_task so the woken task can take over at the next safe preemption point, collapsing the latency to a few microseconds. 2. blocked_resched skips push_back when the task is already queued Enabling preemptive wakes exposes a race in WaitQueue::wait_until. wait_until acquires the queue lock, sets the task state to Blocked and calls blocked_resched. blocked_resched used to unconditionally set in_wait_queue and push the task into the queue. If an AxWaker firing on an unrelated future preempts the task between the previous push_back and the resched call (which is now possible because the AxWaker arms set_preempt_pending), the task can re-enter wait_until and reach blocked_resched a second time while the previous entry is still in the queue. notify_one_with later pops the stale entry and transfers mutex ownership to it; the task subsequently observes the mutex as already owned and panics with "Thread(N) tried to acquire mutex it already owns" on the next aspace().lock(). Guard the push_back with `if !curr.in_wait_queue()`. The flag is still cleared by notify_one_with after a successful pop, so the skip only ever fires when the previous wait is still pending and the task is genuinely already queued. * test(ax-task): add blocked_resched double-enqueue regression test; enable ax-task in CI std test suite 补充审查意见要求的回归测试，验证 blocked_resched 中 `if !curr.in_wait_queue()` 守护能防止 AxWaker::wake_by_ref 直接唤醒路径导致的双重入队。 测试场景： 1. T1 阻塞在 WaitQueue::wait_until（WQ 有 1 条 stale 条目，in_wait_queue=true） 2. 主任务用 select_run_queue::unblock_task 直接唤醒 T1（不清除 in_wait_queue）， 模拟 AxWaker::wake_by_ref with resched=true 的执行路径 3. T1 重跑，条件仍为 false，再次进入 blocked_resched 4. 断言 WQ 最终为空——有幽灵条目则说明双重入队 bug 未被修复 同时修复 ax-task 测试长期未在 CI 运行的问题： - axbuild std 测试 runner 扩展 CSV 格式支持每包 feature 列表 （`package,feat1,feat2,...`，向后兼容旧格式） - std_crates.csv 中 ax-task 改为 `ax-task,multitask,sched-fifo,test`， 使 cargo xtask test 能正常编译并执行调度器测试 Co-Authored-By: Claude Sonnet 4.6 (1M context) --------- Co-authored-by: StarryOS Fix Co-authored-by: Claude Sonnet 4.6 (1M context) --- os/arceos/modules/axtask/src/future/mod.rs | 9 +- os/arceos/modules/axtask/src/run_queue.rs | 14 ++- os/arceos/modules/axtask/src/tests.rs | 67 +++++++++- scripts/axbuild/src/test/std.rs | 135 ++++++++++++++++----- scripts/test/std_crates.csv | 2 +- 5 files changed, 195 insertions(+), 32 deletions(-) diff --git a/os/arceos/modules/axtask/src/future/mod.rs b/os/arceos/modules/axtask/src/future/mod.rs index 018d2958e5..2e1fe4f172 100644 --- a/os/arceos/modules/axtask/src/future/mod.rs +++ b/os/arceos/modules/axtask/src/future/mod.rs @@ -43,7 +43,14 @@ impl Wake for AxWaker { if let Some(task) = self.task.upgrade() { let mut rq = select_run_queue::(&task); *self.woke.lock() = true; - rq.unblock_task(task, false); + // Pass resched=true so set_preempt_pending() is called when the + // task is moved back to ready.

NTTY probes the connected terminal's real dimensions On NTTY initialisation (synchronously, before the input poll task is spawned) the kernel sends the standard cursor-position-report sequence (`\x1b7\x1b[9999;9999H\x1b[6n\x1b8`) and parses the `\x1b[rows;colsR` reply. TIOCGWINSZ then reports the real host terminal size instead of a stale fallback, which is what TUI applications rely on to lay out panels and to translate mouse coordinates to widgets. The wait is bounded to ~100 ms of wall time via `ax_hal::time::wall_time()` so a host that ignores CPR does not delay boot. 2. Default window size 28x110 -> 24x80 24x80 is the standard VT100 fallback that applications expect when TIOCGWINSZ reports a "default" terminal. The previous value was an arbitrary serial-friendly size that confused applications on first paint. 3. SIGWINCH on TIOCSWINSZ Match Linux tty_do_resize(): when an ioctl changes the recorded window size, send SIGWINCH to the foreground process group so TUI applications can re-layout immediately when the user resizes the host terminal. 4. Batched ONLCR output and atomic UART writes write_output_bytes() now collects the `\n -> \r\n` translation into a single Vec and issues exactly one writer.write() call. The previous per-newline issue path produced O(newlines) separate writes; a typical TUI frame contains many cursor-movement newlines, so the COM1 driver acquired/released its lock dozens of times for a single frame and terminal emulators rendered the frame line-by-line (visible flicker). On the x86-qemu-q35 platform the ConsoleIfImpl::write_bytes implementation also holds the COM1 lock for the whole call so that one logical write is never interleaved with output from another task and pays the lock-acquire cost once per write_bytes rather than once per byte.

The removal of these components simplifies the codebase and eliminates the spinning lock mechanism, which may lead to priority inversion issues. This change is aimed at improving overall performance and maintainability. --- Cargo.lock | 5 +- Cargo.toml | 6 +- components/spin/CHANGELOG.md | 162 ---- components/spin/Cargo.toml | 75 -- components/spin/LICENSE | 21 -

The RAII guards returned from the -/// locking methods implement `Deref` (and `DerefMut` for the `write` methods) -/// to allow access to the contained of the lock. -/// -/// An [`RwLockUpgradableGuard`](RwLockUpgradableGuard) can be upgraded to a -/// writable guard through the [`RwLockUpgradableGuard::upgrade`](RwLockUpgradableGuard::upgrade) -/// [`RwLockUpgradableGuard::try_upgrade`](RwLockUpgradableGuard::try_upgrade) functions. -/// Writable or upgradeable guards can be downgraded through their respective `downgrade` -/// functions. -/// -/// Based on Facebook's -/// [`folly/RWSpinLock.h`](https://github.com/facebook/folly/blob/a0394d84f2d5c3e50ebfd0566f9d3acb52cfab5a/folly/synchronization/RWSpinLock.h). -/// This implementation is unfair to writers - if the lock always has readers, then no writers will -/// ever get a chance.

feat(starry): add DeepSeek TUI example app with Docker-based build (#907) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * feat(starry): add DeepSeek TUI example app with Docker-based build 在 StarryOS 上添加 DeepSeek TUI 示例应用，支持在 x86_64 QEMU 中离线 smoke 测试和在线 C 素数测试。 - prepare_deepseek_assets.sh: 在 Alpine Docker 容器中编译 musl 动态链接的 deepseek + deepseek-tui 二进制，处理 libdbus 交叉编译依赖 - prepare_deepseek_rootfs.sh: 构建 Alpine rootfs ext4 镜像，注入二进制、 运行时共享库、CA 证书和 API Key 环境变量 - Dockerfile.build: Alpine + Rust nightly 构建环境 - run_me.sh: 总控脚本，支持 --build/--smoke/--test/--shell 模式 - qemu-x86_64.toml: 离线 smoke 测试（验证 --version 和 model list） - qemu-x86_64-deepseek-prime-test.toml: 在线素数测试 * fix(deepseek-tui): address review comments - Dockerfile.build: use wildcard libdbus-1.so.3* to avoid version-specific path - prepare_deepseek_rootfs.sh: implement --env-file option that was parsed but unused - qemu-x86_64.toml: tighten "No such process" -> "No such process \(os error 3\)" - prepare_deepseek_assets.sh: remove unused $tmp_dir dead code --- apps/starry/deepseek-tui/Dockerfile.build | 37 +++ apps/starry/deepseek-tui/README.md |

charset=UTF-8 Content-Transfer-Encoding: 8bit * Refactor and remove deprecated test files and configurations - Deleted the test framework header file used for syscall testing in the qemu-kcov stress tests. - Removed the CMakeLists.txt and main.c files for the syzkaller-emulation tests, along with its test framework. - Eliminated the threading test files including CMakeLists.txt, main.c, and test_framework.h. - Updated build configurations for aarch64 targets in multiple toml files to enable new features and set platform dynamics. - Simplified the prebuild script for the raw message peek syscall test by directly using apk to install dependencies. - Adjusted shell prompt in the qemu-aarch64 configuration for stress-ng to reflect the root user. * fix(ax-task): preempt on async wake, guard wait queue against double-enqueue (#912) * fix(ax-task): preempt on async wake, guard wait queue against double-enqueue Two small but related scheduler fixes that together remove a latency spike and a panic seen on async I/O paths. 1. AxWaker::wake_by_ref calls unblock_task with resched=true The previous resched=false meant any future woken by an interrupt or another task only became runnable after the currently running task reached its next voluntary yield point. With the default 10 ms timer tick, the visible latency on a two-hop wake (interrupt -> tty reader -> TUI consumer) was up to 20 ms before the consumer started running. Passing resched=true triggers set_preempt_pending() inside unblock_task so the woken task can take over at the next safe preemption point, collapsing the latency to a few microseconds. 2. blocked_resched skips push_back when the task is already queued Enabling preemptive wakes exposes a race in WaitQueue::wait_until. wait_until acquires the queue lock, sets the task state to Blocked and calls blocked_resched. blocked_resched used to unconditionally set in_wait_queue and push the task into the queue. If an AxWaker firing on an unrelated future preempts the task between the previous push_back and the resched call (which is now possible because the AxWaker arms set_preempt_pending), the task can re-enter wait_until and reach blocked_resched a second time while the previous entry is still in the queue. notify_one_with later pops the stale entry and transfers mutex ownership to it; the task subsequently observes the mutex as already owned and panics with "Thread(N) tried to acquire mutex it already owns" on the next aspace().lock(). Guard the push_back with `if !curr.in_wait_queue()`. The flag is still cleared by notify_one_with after a successful pop, so the skip only ever fires when the previous wait is still pending and the task is genuinely already queued. * test(ax-task): add blocked_resched double-enqueue regression test; enable ax-task in CI std test suite 补充审查意见要求的回归测试，验证 blocked_resched 中 `if !curr.in_wait_queue()` 守护能防止 AxWaker::wake_by_ref 直接唤醒路径导致的双重入队。 测试场景： 1. T1 阻塞在 WaitQueue::wait_until（WQ 有 1 条 stale 条目，in_wait_queue=true） 2. 主任务用 select_run_queue::unblock_task 直接唤醒 T1（不清除 in_wait_queue）， 模拟 AxWaker::wake_by_ref with resched=true 的执行路径 3. T1 重跑，条件仍为 false，再次进入 blocked_resched 4. 断言 WQ 最终为空——有幽灵条目则说明双重入队 bug 未被修复 同时修复 ax-task 测试长期未在 CI 运行的问题： - axbuild std 测试 runner 扩展 CSV 格式支持每包 feature 列表 （`package,feat1,feat2,...`，向后兼容旧格式） - std_crates.csv 中 ax-task 改为 `ax-task,multitask,sched-fifo,test`， 使 cargo xtask test 能正常编译并执行调度器测试 Co-Authored-By: Claude Sonnet 4.6 (1M context) --------- Co-authored-by: StarryOS Fix Co-authored-by: Claude Sonnet 4.6 (1M context) * fix(starry-kernel,x86-qemu-q35): probe terminal size, deliver SIGWINCH, batch ONLCR writes (#913) Four serial-console / TTY improvements that together make TUI applications (ratatui-based clients, anything that reacts to SIGWINCH or that draws a full frame per render) usable on the QEMU serial console. 1. NTTY probes the connected terminal's real dimensions On NTTY initialisation (synchronously, before the input poll task is spawned) the kernel sends the standard cursor-position-report sequence (`\x1b7\x1b[9999;9999H\x1b[6n\x1b8`) and parses the `\x1b[rows;colsR` reply. TIOCGWINSZ then reports the real host terminal size instead of a stale fallback, which is what TUI applications rely on to lay out panels and to translate mouse coordinates to widgets. The wait is bounded to ~100 ms of wall time via `ax_hal::time::wall_time()` so a host that ignores CPR does not delay boot. 2. Default window size 28x110 -> 24x80 24x80 is the standard VT100 fallback that applications expect when TIOCGWINSZ reports a "default" terminal. The previous value was an arbitrary serial-friendly size that confused applications on first paint. 3. SIGWINCH on TIOCSWINSZ Match Linux tty_do_resize(): when an ioctl changes the recorded window size, send SIGWINCH to the foreground process group so TUI applications can re-layout immediately when the user resizes the host terminal. 4. Batched ONLCR output and atomic UART writes write_output_bytes() now collects the `\n -> \r\n` translation into a single Vec and issues exactly one writer.write() call. The previous per-newline issue path produced O(newlines) separate writes; a typical TUI frame contains many cursor-movement newlines, so the COM1 driver acquired/released its lock dozens of times for a single frame and terminal emulators rendered the frame line-by-line (visible flicker). On the x86-qemu-q35 platform the ConsoleIfImpl::write_bytes implementation also holds the COM1 lock for the whole call so that one logical write is never interleaved with output from another task and pays the lock-acquire cost once per write_bytes rather than once per byte.

charset=UTF-8 Content-Transfer-Encoding: 8bit loongarch64 上 FP/向量密集的用户程序在信号/抢占下崩溃或挂起:gradle/kotlin 编译器(HotSpot)SIGSEGV(#237);numpy(Alpine,LSX baseline)拒绝 import。这需要三处协同修复——它们**必须同时落地**:只通告 LSX 而不保全它,会让 userspace 的 LSX 运算被信号/上下文切换破坏(比完全不通告更糟)。 ## 根因与修复 ### 1. LSX 高 64 位跨切换/信号丢失(`axcpu/loongarch64/{context.rs,macros.rs}`) 平台启动即开启 LSX 128 位向量(`enable_lsx`,`EUEN.SXE`),用户态(JVM/numpy)用完整 `vr0`-`vr31`,但 `FpuState` 只存低 64 位(标量 `f0`-`f31`)。上下文切换/信号打断 LSX 运算后 `vr[127:64]` 被破坏。 - `FpuState` 增 `fp_high: [u64; 32]`(`vr[127:64]`),`save_fp_registers`/`restore_fp_registers` 经新增 `SAVE_FP_HIGH`/`RESTORE_FP_HIGH` 宏(LSX `vst`/`vld`)存全 128 位。`fp` 保持首位原布局,把 `fp[i]` 当标量 `fN` 的消费者仍见相同值,`fp_high` 纯增量。 ### 2. 信号投递不保存 FP + `uc_mcontext` 偏移错位(`starry-signal/arch/loongarch64.rs`) trap(含信号投递)只存 GPR;异步信号(HotSpot safepoint SIGSEGV)打断 FP 代码后,sigreturn 用 handler 残留 FP 恢复 → 损坏。且 musl loongarch `ucontext_t` 在 `uc_sigmask` 与 `uc_mcontext` 间有 `long __uc_pad`,缺它则 `mcontext` 落早 8 字节,用户 handler 读写 `uc_mcontext` 损坏恢复态。 - `MContext` 增 `fpu: FpuState`(`new()` 前 `fpu.save()` 抓活 FP,`restore()` 恢复 handler 可能破坏的 FP);该 FP 块位于 musl 放 `__extcontext` 处,仅内核管理。 - `UContext` 在 `sigmask` 与 `mcontext` 间增 `__uc_pad: u64`,令 `uc_mcontext` 落回 musl ABI 偏移。 ### 3. `AT_HWCAP` 未通告 LSX(`kernel/src/mm/loader.rs`) ELF 加载器 `aux_vector()` 从不发 `AT_HWCAP`,`getauxval(AT_HWCAP)` 返回 0;numpy 据 `HWCAP_LOONGARCH_LSX`(bit 4)门控 import,缺失即拒绝。 - 新增 `hwcap_value()`:loongarch 报 `CPUCFG|LAM|UAL|FPU|LSX`(匹配 `enable_lsx`;不报 LASX,因未启 `EUEN.ASXE`);其它 arch 报 0(x86 用 CPUID、aarch64 NEON 强制,当前 AT_HWCAP 缺失下已正常,报 0 保持现状)。`aux_vector()` 后 `push(AuxEntry::new(AuxType::HWCAP, hwcap_value()))`。 ## 对照 Linux/musl(验证) Linux loongarch 保存完整 128 位向量(`__extcontext` 含 LSX)、ucontext 有 `__uc_pad`、`ARCH_DLINFO` 发 `AT_HWCAP`;host loongarch 上 JVM/numpy 据此正常。StarryOS 此前三处偏离,本修对齐。 ## 测试 `cargo xtask starry build --arch loongarch64`(及 x86_64,验全 arch auxv 路径)通过;openjdk17(FP/信号密集)loongarch64 实测 1/1 通过;numpy(需 LSX 检测+跨信号保全)在三处齐备下 import 成功。 Signed-off-by: Leo Cheng --- components/axcpu/src/loongarch64/context.rs | 27 +++++- components/axcpu/src/loongarch64/macros.rs | 94 +++++++++++++++++++ .../starry-signal/src/arch/loongarch64.rs | 24 ++++- os/StarryOS/kernel/src/mm/loader.rs | 50 +++++++++- 4 files changed, 190 insertions(+), 5 deletions(-) diff --git a/components/axcpu/src/loongarch64/context.rs b/components/axcpu/src/loongarch64/context.rs index 5ecf64e4e9..968c1bd1ad 100644 --- a/components/axcpu/src/loongarch64/context.rs +++ b/components/axcpu/src/loongarch64/context.rs @@ -43,12 +43,29 @@ pub struct GeneralRegisters { pub s8: usize, } -/// Floating-point registers of LoongArch64 +/// Floating-point / LSX vector registers of LoongArch64. +/// +/// The platform enables the LSX 128-bit vector extension at boot (see +/// `axplat-loongarch64-qemu-virt` `enable_lsx`), so user code (e.g. the JVM) +/// uses the full 128-bit vector registers `vr0`-`vr31`.

<34859362+ZR233@users.noreply.github.com> Date: Tue, 26 May 2026 22:31:31 +0800 Subject: [PATCH 43/71] refactor(starry): route HAL access through ax-runtime (#963) * Refactor kernel to use ax_runtime for HAL functions - Updated references from ax_hal to ax_runtime::hal in various kernel modules, including tty_serial, proc, sysfs, usbfs, and syscall files. - Adjusted IRQ registration and memory management functions to align with the new ax_runtime structure. - Removed deprecated platform dependencies in Cargo.toml and main.rs, streamlining the build configuration. - Enhanced build script to ensure proper feature handling for SG2002 and VF2 platforms. - Updated test configurations to reflect changes in feature requirements for the SG2002 platform. * fix: add dependencies for arceos-wait-queue-remote-wake * feat(irq): implement inter-processor interrupt (IPI) handling * fix: remove unused feature flag 'used_with_arg' from lib.rs * test(starryos): bound clone files race normal case * Add stress tests for buddy slab allocator and enhance GIC driver - Introduced a comprehensive suite of stress tests for the buddy slab allocator, covering various scenarios including random mixed allocation/free, exhaustion recovery, fragmentation recovery, and multithreaded operations. - Enhanced the ARM GIC driver by adding a method to send Software Generated Interrupts (SGIs) to target CPUs, improving interrupt handling capabilities. - Updated dependencies in various Cargo.toml files to include the new buddy slab allocator feature. - Refactored the GlobalAllocator implementation to improve locking mechanisms during allocation and deallocation. - Added new test configurations and scripts for QEMU to validate the buddy slab allocator functionality in a multi-core environment. --- .github/workflows/ci.yml | 9 + Cargo.lock | 82 +- Cargo.toml | 3 +- .../.github/workflows/check.yml | 94 ++ .../.github/workflows/ci.yml | 20 + .../.github/workflows/release-plz.yml |

Stopped exporting the generic allocator traits `BaseAllocator`, `ByteAllocator`, `PageAllocator`, and `IdAllocator` +- Public allocator APIs now favor concrete allocator methods directly instead of requiring trait imports +- Removed `alloc_pages_at` because the current buddy/slab architecture does not stably support fixed-address allocation + +### Removed +- Removed the external allocator-interface crate from `[dependencies]` + +### Migration Notes +- Replace imports of `BaseAllocator`, `ByteAllocator`, `PageAllocator`, and `IdAllocator` with direct method calls on `BuddyPageAllocator`, `CompositePageAllocator`, `SlabByteAllocator`, and `GlobalAllocator` +- `PageAllocatorForSlab` remains available for wiring `SlabByteAllocator` to a page allocator + +## [0.2.0] - 2026-03-05 + +### Added +- Added an external allocator-interface dependency + +### Changed +- `AllocError`, `AllocResult`, `BaseAllocator`, `ByteAllocator`, `PageAllocator`, and `IdAllocator` are now re-exported from the external allocator-interface crate instead of being defined locally +- Updated Rust toolchain to `nightly-2026-02-25` +- Benchmarks no longer require `--features bench`; `criterion` and `rand` moved to `[dev-dependencies]` + +### Removed +- Removed locally defined allocator trait and error type definitions (now provided by the external allocator-interface crate) +- Removed the deprecated `bench` feature flag + +## [0.1.1] - 2026-02-06 + +### Added +- Comprehensive benchmark suite with criterion +- Benchmark documentation in Chinese (`benches/README_CN.md`) +- Benchmark workflow in CI with Rust 1.93.0 toolchain for compatibility + +### Changed +- Increased `MAX_ZONES` from 16 to 32 for more flexible memory region management +- Improved documentation in README with benchmark usage instructions + + +## [0.1.0] - 2025-01-30 + +### Added +- Buddy page allocator implementation for page-level allocation +- Slab byte allocator implementation for small object allocation +- Composite page allocator for unified multi-region page allocation +- Global allocator that coordinates page and byte allocators +- Automatic allocation size selection (≤2048 bytes uses slab, >2048 bytes uses page) +- Zero `std` dependency (`#![no_std]`) for embedded/kernel environments +- Optional `log` feature for logging allocation events +- Optional `tracking` feature for

GlobalAllocator 的分配路径 + +`GlobalAllocator` 是真正对外使用的入口。 + +它把请求分成两类： + +- 小对象：走 slab +- 大对象：走 buddy + +判断条件： + +- `layout.size() <= 2048` +- `layout.align() <= 2048` + +满足才走 slab。 + +### 6.1 alloc 总流程

set_page_flags(addr, Slab) + GA->>P: add_slab(...) + GA->>P: alloc(layout) + P-->>GA: Allocated(ptr) + GA-->>Caller: ptr + end +``` + +这里有一个很重要的锁顺序细节： + +- 当 slab 缺页时，`GlobalAllocator` 会先释放 slab 锁，再去拿 buddy 锁。 + +这样可以避免： + +- 持有 slab 锁时阻塞在 buddy 上。 +- 未来演化成更复杂锁图时出现循环等待。 + +### 6.3 大对象分配 + +大对象路径很直接： + +1. 根据 `layout.size()` 计算页数。 +2. 对齐至少是 `PAGE_SIZE`。 +3. 调用 `BuddyAllocator::alloc_pages()`。 + +大对象不会进入 slab，也不会设置 `PageFlags::Slab`。 + +## 7. dealloc 路径 + +### 7.1 大对象释放 + +大对象释放和分配对称： + +1. 根据 `layout.size()` 推导页数。 +2. 直接进入 `BuddyAllocator::dealloc_pages()`。 + +### 7.2 小对象释放：本地路径 + +如果当前 CPU 就是该 slab 的 owner： + +1. 通过对象地址反推出 slab base。 +2. 拿 owner CPU 对应的 slab 锁。 +3. 调用 `slab.dealloc(ptr, layout)`。 +4. 如果结果是 `Done`，结束。 +5. 如果结果是 `FreeSlab { base, pages }`，释放 slab 锁后把整页还给 buddy。 + +为什么空 slab 不总是立刻还给 buddy： + +- `SlabCache` 会保留一个 empty slab 作为热缓存。 +- 只有当已有一个 cached empty slab 时，新的空 slab 才会还给 buddy。 + +### 7.3 小对象释放：远程路径 + +如果当前 CPU 不是 owner CPU，不会直接拿对方的 slab 锁。 + +而是走 lock-free remote free： + +```mermaid +sequenceDiagram + participant CPU1 as current CPU + participant H as SlabPageHeader + participant CPU0 as owner CPU + participant S as owner SlabCache + + CPU1->>H:

remote 栈中的对象\n重新记回 local bitmap + S-->>CPU0: 对象重新可分配 +``` + +这条路径的核心特点： + +- 释放方不需要知道 owner CPU 的锁状态。 +- 释放方不抢远端锁。 +- owner CPU 在后续本地操作时，顺手把 remote free 合并回 bitmap。 + +这也是当前实现中“跨 CPU free 无锁，但重新利用对象仍由 owner CPU 控制”的关键设计。 + +## 8. 多线程与并发模型 + +### 8.1 并发边界 + +当前实现中真正共享的状态主要有两类： + +- `BuddyAllocator` + 整体包在一个 `SpinMutex` 里，页级操作串行化。 +- 每 CPU 一个 `SlabAllocator` + 每个都各自包在一个 `SpinMutex` 里。 + +因此并发模型可以概括为： + +- 小对象本地路径：只竞争本 CPU 的 slab 锁。 +- 小对象远程 free：不走锁，直接原子 CAS。 +- 缺页或空 slab 回收：会短暂进入全局 buddy 锁。 + +### 8.2 为什么是 per-CPU slab + +如果所有小对象都走单个全局 slab 锁，会有两个问题： + +- 多核下锁竞争重。 +- 小对象热点路径和页级路径容易互相干扰。 + +per-CPU slab 的好处是： + +- 本地分配/释放命中时只碰本 CPU 锁。 +- 跨 CPU free 通过 remote list 延后处理，不把释放方拖进远端临界区。 + +### 8.3 远程释放的正确性依赖 + +远程释放正确性依赖几个事实： + +- slab 页头里记录了 `owner_cpu`。 +- 远程释放只把对象地址压到无锁链表里。 +- owner CPU 持锁 drain 时，再把对象重新放回本地 bitmap。 +- remote 栈中的 next 指针写在对象自身内存开头，这要求被释放对象已经不再被用户使用。 + +### 8.4 锁顺序 + +当前实现中建议理解为以下顺序： + +- 常规 slab 本地路径：只拿 slab 锁。 +- 常规 buddy 页路径：只拿 buddy 锁。 +- slab 缺页：先释放 slab 锁，再拿 buddy 锁，再重新拿 slab 锁。 +- slab 回收空页：先释放 slab 锁，再拿 buddy 锁。 + +这样可以避免出现“持有 slab 锁后等待 buddy，同时另一路持有 buddy 锁又等待 slab”的循环。 + +## 9. 关键实现细节 + +### 9.1 `PageFlags` + +页状态分三种： + +- `Free` +- `Allocated` +- `Slab` + +含义是： + +- `Free`：在 buddy free list 中。 +- `Allocated`：普通页分配返回的块头页。 +- `Slab`：该块当前作为 slab 页使用。 + +### 9.2 buddy 只在块头记录 order + +`PageMeta.order` 只有块头页有意义。 + +因此： + +- 分配时只标记头页的 `order`。 +- 释放时调用方必须传回原始返回地址。 + +### 9.3 `dealloc_pages(count)` 为什么不完全信任 `count` + +因为分配时请求可能被扩大： + +- `count` 会按 buddy order 向上取整。 +- `align` 也可能把块提升到更高阶。 + +所以释放时真正信任的是 `PageMeta.order`，`count` 只用于做 debug 级别的合理性检查。 + +### 9.4 empty slab 缓存策略 + +每个 `SlabCache` 最多保留一个 empty slab。 + +这是一个很重要的折中： + +- 优点：后续同 size class 再分配时更快，减少 buddy 往返。 +- 代价：空闲页不会总是立刻全部回收到 buddy。 + +所以测试或观测时不能简单假设： + +- “所有对象释放后，buddy free pages 一定精确回到初始值”。 + +更准确的理解应是： + +- 除去每 CPU、每 size class 允许缓存的 empty slab 后，应当没有额外页泄漏。 + +## 10. realloc 行为 + +`GlobalAllocator` 通过 `GlobalAlloc` 实现了 `realloc`： + +1. 构造新的 `Layout` +2. 新分配一块内存 +3. 拷贝 `min(old_size, new_size)` 字节 +4. 释放旧块 + +它不是原地扩容，也没有针对 slab/buddy 做特殊优化。 + +## 11. 当前实现的优点与限制 + +### 11.1 优点 + +- 结构清晰，页级与对象级职责分离。 +- 小对象本地路径开销低。 +- 跨 CPU free 不抢远端锁。 +- 初始化不依赖额外堆分配。 +- 支持低地址页分配。 + +### 11.2 限制 + +- buddy 后端仍然是全局单锁。 +- `remote_free` 的对象复用必须等 owner CPU 后续 drain。 +- empty slab 缓存会牺牲一部分“空闲页立刻回收”的极致性。 +- `realloc` 为通用 copy 语义，不做原地优化。 + +## 12. 阅读源码建议 + +如果想快速建立整体理解，建议按下面顺序读： + +1. `src/lib.rs` + 先看公开模块、EII、`SlabPoolTrait` 与 `SlabPoolExt`。 +2. `src/global.rs` + 先理解门面层如何在 buddy/slab 间路由。 +3. `src/buddy/mod.rs` + 看页级分配、拆分和合并。 +4. `src/slab/mod.rs` + 看 slab 与上层的接口契约。 +5. `src/slab/cache.rs` + 看 `partial/full/empty` 三链切换。 +6. `src/slab/page.rs` + 看 bitmap、remote free 栈与 owner CPU drain。 + +## 13. 一句话总结 + +这个分配器的核心思想可以概括成一句话： + +> 用 buddy 统一管理页，用 per-CPU slab 加速小对象，把跨 CPU free 变成“无锁登记、延迟回收”，从而在实现复杂度、局部性和并发开销之间取得平衡。 diff --git a/components/buddy-slab-allocator/rust-toolchain.toml b/components/buddy-slab-allocator/rust-toolchain.toml new file

2026 09:07:52 +0800 Subject: [PATCH 45/71] feat(starry-kernel): add kprobe support (#847) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * feat(starry-kernel): add kprobe support with feature gate Add kernel kprobe subsystem for dynamic kernel function tracing and debugging. The implementation supports x86_64, riscv64, aarch64, and loongarch64 architectures. Key changes: - kprobe.rs: core kprobe implementation with TrapFrame<->PtRegs conversion for all four supported architectures, per-thread kretprobe stack, and SMP-safe registration via stop_machine - Feature-gated with #[cfg(feature = "kprobe")], enabled by default - trap.rs: breakpoint and debug exception handlers with fallback when kprobe is disabled - task/mod.rs: per-thread kretprobe_stack field - Cargo.toml: add kprobe crate dependency (optional) * docs(starry-kernel): add comment for aarch64 SP=0 limitation in kprobe TrapFrame conversion * fix(starry-kernel): address all kprobe PR review feedback 1. KernelRawMutex: replace custom CAS spinlock with spin::Mutex<()> which implements lock_api::RawMutex via the existing spin crate 2. alloc_kernel_exec_memory: use map_alloc() with READ|WRITE|EXECUTE flags to allocate executable memory via the kernel address space instead of the non-executable heap allocator 3. KPROBE_MANAGER: use ax_sync::Mutex instead of SpinNoIrq 4. flush_tlb_range: remove local duplicate, reuse mm/access.rs version (made pub in access.rs, re-exported via mm module) 5. Remove kprobe feature gate: kprobe is now always included - Remove kprobe from [features], make dependency non-optional - Remove all #[cfg(feature = "kprobe")] annotations - Remove Feature Gate section from module docs * fix(starry-kernel): restore kprobe feature gate and add selftest - Restore #[cfg(feature = "kprobe")] gate on kprobe module, trap handlers, and kretprobe_stack field to prevent CI failures on architectures where kprobe runtime behavior is unverified - Add fallback breakpoint/debug handlers that return false when kprobe feature is disabled - Make kprobe dependency optional in Cargo.toml - Add kprobe selftest: register kprobe on a test function, verify handler is called, then unregister - Call run_selftest() during kernel init when kprobe feature is enabled * feat(starry-kernel): add kretprobe selftest * refactor(starry-kernel): remove kprobe feature gate, make kprobe a fixed kernel capability * fix(starry-kernel): skip kprobe selftest on loongarch64 The kprobe selftest causes the CI loongarch64 QEMU test to fail (40min timeout). The kprobe crate's loongarch64 backend needs further validation on QEMU before the selftest can be enabled. Skip the selftest on loongarch64 while keeping the kprobe module fully compiled and functional. * fix(starry-kernel): address kprobe review feedback — SpinNoIrq, aarch64 comment, hint param - Replace ax_sync::Mutex with ax_sync::spin::SpinNoIrq for KPROBE_MANAGER to prevent potential sleep-in-exception-context on SMP systems - Restore aarch64 SP=0 comment explaining TrapFrame does not store SP - Use guard.base() instead of VirtAddr::from(0) as find_free_area hint for clearer intent when searching kernel address space * fix(starry-kernel): remove broken kcov feature reference after rebase * chore(starry-kernel): re-trigger CI for kprobe PR --- Cargo.lock | 34 ++ os/StarryOS/kernel/Cargo.toml | 1 + os/StarryOS/kernel/src/entry.rs | 5 + os/StarryOS/kernel/src/kprobe.rs | 474 ++++++++++++++++++++++++++++ os/StarryOS/kernel/src/lib.rs | 1 + os/StarryOS/kernel/src/mm/access.rs | 2 +- os/StarryOS/kernel/src/task/mod.rs | 3 + os/StarryOS/kernel/src/trap.rs | 8 +- 8 files changed, 523 insertions(+), 5 deletions(-) create mode 100644 os/StarryOS/kernel/src/kprobe.rs diff --git a/Cargo.lock b/Cargo.lock index 88a87e4e53..e4084c2efa 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -4987,6 +4987,19 @@ dependencies = [ "bitflags 2.11.1", ] +[[package]] +name = "kprobe" +version = "0.5.5" +source = "registry+https://github.com/rust-lang/crates.io-index" +checksum = "1cf6b7b70ff393b62d067f6f2e35bd64c9278ac77fd6fa2de883b2c0be8fa5ff" +dependencies = [ + "cfg-if", + "lock_api", + "log", + "yaxpeax-arch", + "yaxpeax-x86", +] + [[package]] name = "ktest-helper" version = "0.1.1" @@ -7964,6 +7977,7 @@ dependencies = [ "indoc", "inherit-methods-macro", "kernel-elf-parser", + "kprobe", "ktracepoint", "linux-raw-sys 0.12.1", "lock_api", @@ -10193,6 +10207,26 @@ version = "1.0.1" source = "registry+https://github.com/rust-lang/crates.io-index" checksum = "cfe53a6657fd280eaa890a3bc59152892ffa3e30101319d168b781ed6529b049" +[[package]] +name = "yaxpeax-arch" +version = "0.3.2" +source = "registry+https://github.com/rust-lang/crates.io-index" +checksum = "36274fcc5403da2a7636ffda4d02eca12a1b2b8267b9d2e04447bd2ccfc72082" +dependencies = [ + "num-traits", +] + +[[package]] +name = "yaxpeax-x86" +version = "2.0.0" +source = "registry+https://github.com/rust-lang/crates.io-index" +checksum = "9a9a30b7dd533c7b1a73eaf7c4ea162a7a632a2bb29b9fff47d8f2cc8513a883" +dependencies = [ + "cfg-if", + "num-traits", + "yaxpeax-arch", +] + [[package]] name = "yoke" version = "0.8.2" diff --git a/os/StarryOS/kernel/Cargo.toml b/os/StarryOS/kernel/Cargo.toml index 1531ea32af..90af40394d 100644 --- a/os/StarryOS/kernel/Cargo.toml +++ b/os/StarryOS/kernel/Cargo.toml @@ -131,6 +131,7 @@ zerocopy = { version = "0.8", features = ["derive"] } ax-ipi = { workspace = true } static-keys = "0.8" ddebug = "0.5" +kprobe = "0.5" dw_apb_uart = { workspace = true, features = ["sg2002"], optional = true } sg200x-bsp = { workspace = true, optional = true } # 0.9 to match sg200x-bsp's internal tock-registers; cannot use workspace (0.10) diff --git a/os/StarryOS/kernel/src/entry.rs b/os/StarryOS/kernel/src/entry.rs index 0e00b1728b..5e5ac35e70 100644 --- a/os/StarryOS/kernel/src/entry.rs +++ b/os/StarryOS/kernel/src/entry.rs @@ -22,6 +22,11 @@ pub fn init(args: &[String], envs: &[String]) { static_keys::global_init(); tracepoint_init().expect("Failed to initialize tracepoints"); + // FIXME: loongarch64 selftest hangs on QEMU; the kprobe crate's loongarch64 + // breakpoint handling needs upstream fixes before selftest can be enabled. + #[cfg(not(target_arch = "loongarch64"))] + crate::kprobe::run_selftest(); + pseudofs::mount_all().expect("Failed to mount pseudofs"); spawn_alarm_task(); diff --git a/os/StarryOS/kernel/src/kprobe.rs b/os/StarryOS/kernel/src/kprobe.rs new file mode 100644 index 0000000000..d7ecb2bfa3 --- /dev/null +++ b/os/StarryOS/kernel/src/kprobe.rs @@ -0,0 +1,474 @@ +//!

and related documentation. - Introduced a new DesignWare APB UART backend for NS16550-compatible core in the `some-serial` module. - Updated the `some-serial` module to support DesignWare APB UART alongside existing NS16550 implementations. - Modified the kernel and device drivers to utilize the new `some-serial` module instead of the removed ARM PL011 driver. - Adjusted Cargo.toml dependencies to reflect the removal of `dw_apb_uart` and the addition of `some-serial`. --- Cargo.lock | 31 +-- Cargo.toml | 2 - .../axplat-aarch64-bsta1000b/Cargo.toml | 2 +-

-> 路径：`drivers/serial/arm_pl011` -> 类型：库 crate -> 分层：组件层 / AArch64 外设叶子实现 -> 版本：`0.1.0` -> 文档依据：当前仓库源码、`Cargo.toml`、`README.md`、`src/lib.rs`、`src/pl011.rs`、`components/axplat_crates/platforms/axplat-aarch64-peripherals/src/pl011.rs` - -`ax-arm-pl011` 是一个非常典型的**设备叶子 crate**：它只关心 ARM PL011 UART 的寄存器布局和最基础的收发/中断确认操作，对上层暴露一个 `Pl011Uart` 结构体。它不是串口子系统、不是控制台框架，也不负责平台发现、时钟配置、锁保护或缓冲策略。 - -## 架构设计 - -### 设计定位 - -从 `src/pl011.rs` 可以看出，这个 crate 的问题域很窄： - -- 把 PL011 的寄存器布局声明出来 -- 按固定寄存器语义完成最基本的初始化 -- 提供阻塞写、非阻塞读和简单中断判断/清除 - -它明确不做： - -- 波特率计算与分频寄存器配置 -- pinmux、时钟源、复位时序 -- 缓冲队列、中断驱动收发、DMA -- 多实例管理与并发同步 - -因此它更像“可复用的 MMIO 叶子驱动”，适合被平台层拿去二次封装。 - -### 1.2 内部结构 - -整个 crate 只有一个核心模块 `pl011`，内部结构也很直接： - -| 组成 | 作用 | -| --- | --- | -| `Pl011UartRegs` | 用 `tock_registers::register_structs!` 描述寄存器布局 | -| `Pl011Uart` | 保存基地址并提供对外方法 | -| `regs()` | 把 `NonNull` 转成寄存器视图 | - -已声明并实际使用的寄存器包括： - -- `dr`：数据寄存器 -- `fr`：状态寄存器 -- `cr`：控制寄存器 -- `ifls`：FIFO 触发阈值 -- `imsc`：中断 mask -- `mis`：中断状态 -- `icr`：中断清除 - -这再次说明它只覆盖当前平台接线真正需要的一小部分 PL011 能力。 - -### 1.3 运行模型 - -`Pl011Uart` 的运行模型非常简单： - -1. `new(base)` 保存 UART 的 MMIO 基地址 -2. `init()` 对几组关键寄存器做最小初始化 -3. `putchar()` 轮询 `FR.TXFF`，等待发送 FIFO 可写 -4. `getchar()` 读取 `FR.RXFE`，在有数据时返回一个字节 -5. `is_receive_interrupt()` / `ack_interrupts()` 处理接收中断状态 - -这里没有任何后台线程、状态机或缓冲结构，所有行为都以调用者的时序为准。 - -### 1.4 `init()` 实际做了什么 - -`init()` 的实现只做了四件事： - -- `ICR = 0x7ff`，清空中断 -- `IFLS = 0`，把 FIFO 触发阈值设为 1/8 -- `IMSC = 1 << 4`，打开接收中断 -- `CR = (1 << 0) | (1 << 8) | (1 << 9)`，启用 UART、发送和接收 - -值得注意的是，它**没有**设置波特率寄存器，也没有配置行控制寄存器。这通常意味着： - -- 某些平台默认配置已经足够 -- 或者这些设置在更早的引导阶段完成 -- 或者当前使用场景只需要最小可用收发能力 - -### 1.5 与平台层的真实关系 - -在当前仓库中，真实消费者是 `ax-plat-aarch64-peripherals` 的 `pl011.rs`： - -- 用 `LazyInit>` 管理全局实例 -- 在 `init_early()` 中调用 `Pl011Uart::new()` 和 `init()` -- `putchar()` 上层额外做了 `\n -> \r\n` 转换 -- 通过 `console_if_impl!` 宏把它接到 `ax_plat::console::ConsoleIf` - -这条调用链说明： - -- `ax-arm-pl011` 本身不负责平台抽象 -- 平台层才负责把这个叶子驱动接进整个控制台接口 - -## 核心功能 - -### 功能概览 - -- 基于基地址构造 `Pl011Uart` -- 对 UART 做最小初始化 -- 发送单字节 -- 非阻塞接收单字节 -- 判断是否出现接收中断 -- 清除全部中断 - -### 2.2 关键接口 - -| 接口 | 作用 | -| --- | --- | -| `Pl011Uart::new(base)` | 根据 MMIO 基地址创建实例 | -| `init()` | 清中断、设 FIFO 阈值、开 RX 中断、启用 UART | -| `putchar(c)` | 轮询发送一个字节 | -| `getchar()` | 若接收 FIFO 非空则取一个字节 | -| `is_receive_interrupt()` | 检查接收中断是否 pending | -| `ack_interrupts()` | 清除中断 | - -### 2.3 最关键的边界 - -这个 crate 只到“寄存器薄封装”为止，不包含： - -- 控制台抽象 -- 终端行规约 -- 串口驱动线程 -- 设备树发现 -- IRQ 框架集成 -- 多核共享时的锁 - -因此把它写成“串口子系统”会明显高估它的职责。 - -## 依赖关系 - -### 直接依赖 - -| 依赖 | 作用 | -| --- | --- | -| `tock-registers` | 声明 MMIO 寄存器结构和读写接口 | -

-### 3.3 关系解读 - -| 层级 | 角色 | -| --- | --- | -| `ax-arm-pl011` | 叶子寄存器驱动 | -| `ax-plat-aarch64-peripherals` | 把叶子驱动接成 `axplat` 可用控制台 | -| ArceOS/StarryOS/Axvisor 的 AArch64 平台 | 通过平台层间接获得早期串口输出能力 | - -## 开发指南 - -### 4.1 适用场景 - -适合直接使用 `ax-arm-pl011` 的场景是： - -- 平台代码已经知道 UART 基地址 -- 需要最小串口输入输出能力 -- 同步/锁、换行策略、控制台接口想在上层自定义 - -不适合直接把它当成： - -- 通用 TTY 层 -- 高性能串口驱动 -- 带缓存和异步队列的串口子系统 - -### 4.2 修改时要特别注意的点 - -- 寄存器偏移必须严格符合 PL011 手册 -- `putchar()` 的轮询条件和 `getchar()` 的空/非空条件不要写反 -- `init()` 当前是“最小可用初始化”，新增配置项时要确认不会破坏已有平台假设 -- 若要支持并发访问，应在上层加锁，而不是让该 crate 直接耦合平台同步原语 - -### 4.3 若要扩展功能，推荐放在哪一层 - -- 时钟、波特率、设备树解析：放在平台 crate -- 控制台 trait 对接：放在平台或 HAL 适配层 -- 缓冲、中断驱动收发：放在更高层驱动封装 -- 这里只保留 PL011 硬件原语 - -## 测试 - -### 测试覆盖 - -当前 crate 内没有单独的 `tests/`。实际回归主要依赖： - -- 编译检查 -- `ax-plat-aarch64-peripherals` 的平台接线 -- 系统启动后控制台是否可用 - -### 单元测试 - -- 用伪 MMIO 区验证 `init()` 写入了预期寄存器值 -- 验证 `putchar()` 在 `TXFF` 为 1 时会等待 -- 验证 `getchar()` 在 `RXFE` 为 0 时返回正确数据 -- 验证 `is_receive_interrupt()` / `ack_interrupts()` 的位语义 - -### 集成测试 - -- 在使用 PL011 的 AArch64 平台上做启动打印回归 -- 验证中断模式下输入路径能否被上层平台正确接入 -- 验证 `\n` 的 CRLF 行为确实由平台层而非本 crate 提供 - -### 5.4 风险点 - -- 基地址映射错误会让所有访问落到错误 MMIO 区 -- 当前初始化没有处理全部 UART 配置，平台若假设更多寄存器已设定，可能需要补接线 -- 该 crate 默认不加锁，多核共享访问必须由外层保证 - -## 跨项目定位 - -| 项目 | 位置 | 角色 | 说明 | -| --- | --- | --- | --- | -| ArceOS | AArch64 平台外设栈 | 控制台叶子驱动 | 经 `ax-plat-aarch64-peripherals` 间接接入 | -| StarryOS | 共享平台基础设施 | 可复用串口叶子驱动 | 复用 `axplat` 平台路径时可间接使用 | -| Axvisor | 共享平台基础设施 | 早期控制台叶子驱动 | 若选择同一 AArch64 平台实现，可由平台层间接复用 | - -## 总结 - -`ax-arm-pl011` 的价值在于把 PL011 UART 的最基础硬件语义稳定地收敛成一个小而清晰的 API。它既不重，也不“全”，真正的定位是**设备叶子实现**：只处理寄存器，只暴露原语，把平台抽象、锁、中断编排和控制台策略留给上层。 diff --git a/docs/docs/components/crates/ax-display.md b/docs/docs/components/crates/ax-display.md index a8fa0253ab..447782f9a7 100644 --- a/docs/docs/components/crates/ax-display.md +++ b/docs/docs/components/crates/ax-display.md @@ -46,7 +46,6 @@ graph LR -

arm_vgic axaddrspace From 046c240eede40f8fdc5bb10839ef1ac4c4066562 Mon Sep 17 00:00:00 2001 From: ZCShou <72115@163.com> Date: Wed, 27 May 2026 10:20:17 +0800 Subject: [PATCH 48/71] Refactor FDT handling, error management, and improve code clarity (#966) * Refactor FDT handling and improve error handling - Updated CPU node filtering logic in `create.rs` to pass node path directly. - Modified `build_node_path` function in `device.rs` to only compile for tests. - Enhanced error handling in FDT operations in `mod.rs`, returning `AxResult` for better error propagation. - Improved FDT parsing and setup functions in `parser.rs` to return results instead of panicking on errors. - Refactored image loading logic in `images/mod.rs` to use `AxResult` for error handling and removed unsafe static mut usage. - Updated vCPU task management in `vcpus.rs` to use thread-safe structures and improved error handling. - Enhanced command-line argument normalization in `xtask/src/main.rs` for better path resolution across platforms. * Refactor FDT handling and error management - Updated FDT creation functions to return AxResult for better error handling. - Introduced fdt_write_err function to standardize error reporting for FDT write operations. - Enhanced error handling in various FDT-related functions to ensure proper error propagation. - Modified the VM list management to simplify the structure and improve thread safety. - Replaced the custom VMList struct with a direct BTreeMap for global VM management. - Adjusted memory image handling to utilize the updated configuration access methods. - Improved the handling of IVC channels to ensure proper memory management and error checking. - Refined timer token management for better atomic operations. - Updated vCPU task management to use a BTreeMap for more efficient task retrieval and management. * refactor: streamline flag handling and improve code clarity across multiple commands * refactor: integrate startup banner into main kernel entry point * feat: add get_or_init method for LazyInit and implement DTB cache initialization --- Cargo.lock | 1 + components/ax-lazyinit/src/lib.rs | 27 +++ os/axvisor/.gitmodules | 0

Fix test install path: usr/bin -> usr/bin/starry-test-suit (tests were silently skipped by qemu toml wildcard) 2. Add BPF_EXIT instruction handling in BpfVm::execute: opcode 0x90 now returns Ok(regs[0]) instead of falling through 3. Fix pointer truncation in handle_prog_load: read u64 fields correctly using *const u64 instead of *const u32 (was losing high 32 bits on 64-bit architectures) 4. Add BPF_CALL instruction handling (opcode 0x85): looks up helper by insn.imm, calls with regs[1..5] as args, stores result in regs[0] * fix(starry-kernel): correct bpf_attr field offsets in handle_prog_load Previous fix changed *const u32 to *const u64 which was wrong because Linux bpf_attr is a mixed u32/u64 layout. Use byte-offset helpers: read_u32(0) = prog_type (+0, u32) read_u32(4) = insn_cnt (+4, u32) read_u64(8) = insns (+8, u64 ptr) read_u64(16) = license (+16, u64 ptr) read_u32(24) = log_level (+24, u32) read_u32(28) = log_size (+28, u32) read_u64(32) = log_buf (+32, u64 ptr) read_u32(40) = kern_version (+40, u32) read_u32(44) = prog_flags (+44, u32) Verified: clippy 11 features, loongarch64 + x86_64 build. * fix(starry-kernel): improve eBPF helper safety per review suggestions 1. helper_map_lookup_elem: return pointer to cached value instead of map fd. Uses BPF_LOOKUP_CACHE global Vec to store the lookup result and returns its raw pointer, matching Linux bpf_map_lookup_elem semantics where BPF programs can directly read the value. 2. helper_probe_read: add safety improvements - Size limit: reject reads > 4096 bytes - User/kernel address detection: for addresses below 0x8000_0000_0000 (likely userspace), try vm_read_slice first; fall back to direct copy for kernel addresses - Prevents arbitrary kernel memory reads from unvalidated addresses 3. Add SAFETY comment for BPF_LOOKUP_CACHE explaining pointer lifetime Verified: clippy 11 features, x86_64/loongarch64 build. * feat(starry-kernel): add BPF/perf_event fd close and resource release BpfFdTable: - remove_map(fd): remove and drop a BPF map by fd - remove_prog(fd): remove and drop a BPF prog by fd - close_fd(fd): close either map or prog fd - fd_exists(fd): check if fd is a valid BPF fd - get_prog(fd): get mutable reference to BpfProg by fd Perf events: - perf_event_close(fd): remove and drop a perf event entry by fd - perf_event_fd_exists(fd): check if fd is a valid perf event fd Syscall routing: - Add BPF_OBJ_CLOSE (cmd=11) handler in sys_bpf - handle_obj_close reads fd from uattr and calls close_fd Public API: - bpf_close_fd(fd) / bpf_fd_exists(fd) for external callers - perf_event_close(fd) / perf_event_fd_exists(fd) for external callers Verified: clippy 11 features, x86_64/riscv64/aarch64/loongarch64 build. * fix(starry-kernel): improve eBPF handle_link_create and helper_get_current_uid_gid 1. handle_link_create: return newly allocated link fd instead of target_fd, matching Linux BPF_LINK_CREATE semantics 2. helper_get_current_uid_gid: read actual uid/gid from current thread credentials via AsThread trait instead of hardcoding 0 Returns (gid << 32) | uid as per Linux eBPF convention Verified: clippy 12 features, x86_64/loongarch64 build. * fix(starry-kernel): remove hardcoded user/kernel address boundary in helper_probe_read Instead of using a hardcoded 0x8000_0000_0000 boundary (x86_64-specific), always try vm_read_slice first for safe access, falling back to direct copy on failure. This works correctly on all architectures without platform-specific constants. Verified: clippy 12 features passed. * fix(starry-kernel): add fd reuse via free list in BpfFdTable Previously, BpfFdTable used a simple counter that never reused freed fd numbers, potentially exhausting fd space over long runs. Now uses a free_fds Vec as a LIFO free list: - alloc_fd() pops from free_fds if available, otherwise increments counter - close_fd() pushes the released fd back to free_fds - Verified: clippy 12 features passed * docs(starry-kernel): add module-level documentation for eBPF and perf_event the subsystem components, syscall interface, and public API. * fix(starry-kernel): address eBPF PR review non-blocking feedback 1. BpfFdTable: add links field to track link_fd -> (prog_fd, target_fd) mapping, enabling proper link lifecycle management 2. handle_link_create: record link in BpfFdTable.links so the returned fd is tracked and can be closed via OBJ_CLOSE 3. close_fd: handle links cleanup alongside maps and progs 4. handle_prog_attach: rename prog_fd to attach_prog_fd to match Linux bpf_attr PROG_ATTACH semantics (attach_prog_fd at offset 0) * fix(starry-kernel): correct bpf_attr field read order in handle_link_create and handle_prog_attach * fix(starry-kernel): improve eBPF code quality and close(2) integration - Fix BPF_ALU 32-bit truncation: all ALU ops now apply correct mask when is_64=false, not just RSH/ARSH - Define BPF_CALL_OP named constant for magic number 0x80 - Fix alloc_perf_fd TOCTOU: fd allocation and Vec push now atomic under same lock via new PerfFdTable with fd reuse support - Unify fd namespace: perf_event fd now starts from 3 (was 100) - Integrate perf_event_close/bpf_close_fd into close(2) syscall path and close_all_fds for process exit cleanup - Convert BPF_LOOKUP_CACHE from global SpinNoIrq to per-CPU via ax_percpu::def_percpu for SMP safety - Add perf event trigger mechanism: run_bpf_prog is called when perf events fire, enabling end-to-end BPF program execution - Wire kprobe breakpoint/debug handlers to trigger KPROBE perf events * fix(starry-kernel): correct BPF source operand check in ALU and JMP interpreters Use opcode bit check (insn.code & BPF_X) instead of incorrectly comparing register number (insn.src_reg()) with the BPF_X flag value. The old code caused all register-source ALU/JMP instructions to incorrectly use the immediate field instead of the source register. * fix(starry-kernel): correct JMP32 JA unconditional jump check in eBPF interpreter Use explicit opcode comparison (BPF_JMP32 | BPF_JA) instead of checking src_reg() == 0, which incorrectly matches any BPF_K conditional jump instruction (JEQ32, JGT32, etc.) as an unconditional jump. * fix(starry-kernel): add ebpf feature gate for conditional compilation - Cargo.toml: add "ebpf" feature (default enabled) - lib.rs: gate mod ebpf and mod perf_event behind #[cfg(feature = "ebpf")] - syscall/mod.rs: route bpf/perf_event_open to dummy_fd when ebpf disabled - file/mod.rs: gate perf_event_close/bpf_close_fd behind #[cfg(feature = "ebpf")] - kprobe.rs: gate perf_event_trigger_by_type behind #[cfg(feature = "ebpf")] - Verified: clippy 13 features all pass * feat(starry-kernel): add eBPF verifier, PERF_EVENT_ARRAY map, more helpers and prog type validation - Add basic eBPF verifier: instruction count limit (1M), BPF_EXIT existence check, PC jump boundary validation - Add PERF_EVENT_ARRAY map type with full BpfMapOps implementation - Register 3 new helpers: trace_printk (id=6), get_current_task (id=35), get_current_comm (id=16) - Add prog_type whitelist validation in handle_prog_load - Verified: clippy 13/13 features pass * fix(starry-kernel): rebase onto dev with kprobe merged, resolve conflicts --- os/StarryOS/kernel/Cargo.toml | 3 +- os/StarryOS/kernel/src/ebpf.rs | 1503 +++++++++++++++++ os/StarryOS/kernel/src/file/mod.rs | 24 +- os/StarryOS/kernel/src/kprobe.rs | 10 + os/StarryOS/kernel/src/lib.rs | 4 + os/StarryOS/kernel/src/perf_event.rs | 508 ++++++ os/StarryOS/kernel/src/syscall/mod.rs | 15 +- .../syscall/test-ebpf-basics/c/CMakeLists.txt | 9 + .../syscall/test-ebpf-basics/c/src/main.c | 405 +++++ 9 files changed, 2472 insertions(+), 9 deletions(-) create mode 100644 os/StarryOS/kernel/src/ebpf.rs create mode 100644 os/StarryOS/kernel/src/perf_event.rs create mode 100644 test-suit/starryos/normal/qemu-smp1/syscall/test-ebpf-basics/c/CMakeLists.txt create mode 100644 test-suit/starryos/normal/qemu-smp1/syscall/test-ebpf-basics/c/src/main.c diff --git a/os/StarryOS/kernel/Cargo.toml b/os/StarryOS/kernel/Cargo.toml index 54289cd536..9efe2b1e5a 100644 --- a/os/StarryOS/kernel/Cargo.toml +++ b/os/StarryOS/kernel/Cargo.toml @@ -14,10 +14,11 @@ repository.workspace = true license.workspace = true [features] -default = ["dynamic_debug"] +default = ["dynamic_debug", "ebpf"] dev-log = [] ext4 = ["ax-fs/ext4"] input = ["dep:ax-input", "ax-feat/input"] +ebpf = [] memtrack = ["ax-feat/dwarf", "ax-alloc/tracking", "dep:gimli"] rknpu = ["dep:ax-driver", "ax-driver/rknpu"] plat-dyn = [ diff --git a/os/StarryOS/kernel/src/ebpf.rs b/os/StarryOS/kernel/src/ebpf.rs new file mode 100644 index 0000000000..99b3a1e0d9 --- /dev/null +++ b/os/StarryOS/kernel/src/ebpf.rs @@ -0,0 +1,1503 @@ +//! eBPF (Extended Berkeley Packet Filter) subsystem for StarryOS. +//! +//!

[PATCH 52/71] Adds support for kernel symbol dumping via kallsyms (#837) * Adds support for kernel symbol dumping via kallsyms Introduces infrastructure to extract, store, and expose kernel symbol information, enabling access via a dedicated procfs file. Integrates kallsyms section in the linker script, a build script for symbol extraction, and updates the build process to automate symbol generation. Signed-off-by: Godones * fix(starry): avoid qemu panic matcher for kallsyms output Upgrade ostool to 0.19 so empty QEMU fail_regex no longer gets default panic patterns injected, then clear the default Starry QEMU fail_regex entries to avoid terminating interactive QEMU sessions when /proc/kallsyms prints symbols containing "panic". Adjust axbuild for the new ostool Cargo fields, and refine pseudofs helpers so static string content can be exposed without overlapping trait impls while keeping read-only write failures as BadFileDescriptor. Signed-off-by: Godones * fix: Updates kallsyms handling and bumps ksym dependency. Signed-off-by: Godones * Improves kallsyms reading and initialization logic.

The following files and directories were removed: - platforms/examples/hello-kernel/ - platforms/examples/irq-kernel/ - platforms/examples/smp-kernel/ These examples included build scripts, linker scripts, source code, and documentation files. The removal is part of a restructuring effort to streamline the project and focus on core components. --- Cargo.lock | 183 +++++------ Cargo.toml | 40 +-- .../axplat_crates/.github/workflows/check.yml

-`smp-kernel` 是 `axplat` 示例里最完整的一条 bring-up 样例。它不只验证主核启动，还验证次核 boot、`#[ax_plat::secondary_main]` 入口、per-CPU 数据、中断在多核上的工作方式，以及所有 CPU 完成初始化后的同步收敛。 - -因此必须先把边界说透：**它不是可复用 SMP 框架，也不是 ArceOS `ax-runtime` 的替代实现；它只是把 `axplat` 的多核启动链用最小内核样例形式跑通。** - -## 架构设计 -### 模块结构 -与前两个样例不同，这个 crate 已经拆成了三个明确模块： - -- `init.rs`：主核/次核的初始化共性与 `INITED_CPUS` 同步计数 -- `mp.rs`：次核栈、`cpu_boot()` 和 `#[ax_plat::secondary_main]` -- `irq.rs`：多核场景下的定时器中断注册与 per-CPU 下一次到期时间 - -这说明它的关注点已经从“最小启动”扩展到“多核 bring-up 协同”。 - -### 1.2 主核与次核主线 -主核路径大致是： - -```mermaid -flowchart TD - A["#[ax_plat::main] main"] --> B["init_kernel(primary)"] - B --> C["start_secondary_cpus()"] - C --> D["init_irq()"] - D --> E["INITED_CPUS += 1"] - E --> F["等待所有 CPU 完成初始化"] - F --> G["busy_wait 5s"] - G --> H["system_off()"] -``` - -次核路径则是： - -```mermaid -flowchart TD - A["cpu_boot() 唤起次核"] --> B["#[ax_plat::secondary_main]"] - B --> C["init_kernel_secondary()"] - C --> D["INITED_CPUS += 1"] - D --> E["等待全部 CPU 就绪"] - E --> F["enable_irqs()"] - F --> G["自旋等待并处理中断"] -``` - -### 1.3 关键同步点 -这个样例里有两个非常关键的同步设计： - -1. `start_secondary_cpus()` 在逐个启动 AP 后，等待 `INITED_CPUS` 增长，确保主核知道 AP 至少已进入初始化完成点。 -2. 主核和次核都调用 `init_smp_ok()`，等到 `INITED_CPUS == CPU_NUM` 后才进入下一阶段。 - -因此它验证的不是“能 boot 第二个核”这么简单，而是“多核初始化能否有序收敛”。 - -## 核心功能 -### 2.1 `CPU_NUM` 与运行规模 -`CPU_NUM` 不是写死在源码里，而是： - -- 优先取环境变量 `AX_CPU_NUM` -- 否则退回平台配置里的 `MAX_CPU_NUM` - -而 `Makefile` 又会把 `SMP=` 导出为 `AX_CPU_NUM`。这让样例可以直接通过： - -```bash -make ARCH=riscv64 run SMP=4 -``` - -在不同核数下复用同一份代码。 - -### 2.2 `mp.rs` 的启动责任 -`start_secondary_cpus()` 里做了三件真实而关键的事情： - -- 为每个 AP 分配独立 boot stack -- 把该栈顶虚拟地址转成物理地址 -- 调用 `ax_plat::power::cpu_boot(i, stack_top_paddr)` - -这条链是 `axplat` 平台支持多核的核心契约之一。 - -### 2.3 `irq.rs` 的 per-CPU 定时器逻辑 -与 `irq-kernel` 不同，这里用的是： - -- `#[ax_percpu::def_percpu] static NEXT_DEADLINE: u64 = 0;` - -这说明在多核场景下，每个 CPU 都维护自己下一次 one-shot timer 的到期时间。它不是全局共享一个 deadline，而是显式验证 per-CPU 数据和多核 timer IRQ 是否能共存。 - -### 2.4 边界澄清 -这个样例不负责： - -- 提供通用的 SMP runtime -- 管理任务调度 -- 作为上层 OS 多核框架直接复用 - -它只是最小内核级的多核 bring-up 演示。 - -## 依赖关系 -```mermaid -graph LR - sample["smp-kernel"] --> axplat["ax-plat"] - sample --> ax-cpu["ax-cpu"] -

14:12:14 +0800 Subject: [PATCH 54/71] Refactor code structure for improved readability and maintainability (#982) * Add range allocator tests and implement range operations - Introduced tests for the RangeAllocator including simple allocation, out of memory scenarios, fragmentation and merging, and alignment gaps. - Created a CHANGELOG.md for the ranges-ext module to document notable changes. - Added Cargo.toml for the ranges-ext module with dependencies and features. - Implemented VecOp trait for heapless::Vec and alloc::vec::Vec to support range operations. - Developed the core functionality for merging overlapping ranges and handling conflicts in the ranges-ext module. - Added comprehensive tests for merging ranges, ensuring correct behavior for various scenarios including overlaps and conflicts. * Refactor code structure for improved readability and maintainability * Refactor workspace dependencies and update component paths for consistency * refactor: restructure axplat-dyn platform module - Remove obsolete files related to platform initialization, IRQ handling, memory management, power management, and generic timer. - Introduce new files for boot, console, drivers, and memory management with updated implementations. - Implement a new build script and linker script for dynamic platform support. - Update Cargo.toml to reflect the new structure and dependencies. - Add CHANGELOG.md to document changes and versioning. - Ensure compatibility with the latest spin crate version. --- Cargo.lock | 48 ++--- Cargo.toml | 93 +++-----

Content-Transfer-Encoding: 8bit * chore(deps): update spin 0.10→0.12, ostool 0.19→0.21 - Update workspace spin from 0.10 to 0.12, rename Lazy→LazyLock across all usage sites to match spin 0.11+ API - Migrate 16 crates from pinned `spin = "0.10"` to `workspace = true` - Update `lazy` feature to `lazylock` for spin 0.12 compatibility - Update ostool from 0.19 to 0.21 (no code changes needed) * chore: format static LazyLock initializations for consistency * chore: replace Mutex with SpinMutex in IrqLock for improved performance * chore: remove ax-plat-dyn package and update spin dependency

Fix test install path: usr/bin -> usr/bin/starry-test-suit (tests were silently skipped by qemu toml wildcard) 2. Fix KmodSectionMem null-pointer Drop UB: - Add null check in Drop before calling dealloc - Replace null-ptr KmodSectionMem fallback with safe NullSectionMem (no-op SectionMemOps implementation) to avoid UB entirely 3. Add comment explaining core::mem::forget(owner) intent: module must remain in memory; future delete_module will recover owner via global registry Verified: clippy 11 features, x86_64/riscv64/aarch64/loongarch64 build. * docs(starry-kernel): add module-level documentation for kmod_loader Add module doc comments describing LKM support, key components (KmodSectionMem, NullSectionMem, StarryKmodHelper), and known limitations. Fix module ordering in lib.rs for rustfmt. * fix(starry-kernel): address kmod review non-blocking suggestions - resolve_symbol stub: use AtomicBool to warn only once, avoid log spam - add test cases for valid ET_REL header, fd=0, and large junk input * fix(starry-kernel): use literal 0x80 for BPF_CALL opcode in verifier BPF_CALL_OP constant does not exist in bpf_insn module. BPF_CALL opcode is 0x85, so the high nibble is 0x80. * fix(starry-kernel): rebase onto dev with kprobe+eBPF merged, resolve conflicts - Skip kprobe and eBPF commits (already in dev via #847 + #848) - Resolve lib.rs, syscall/mod.rs, Cargo.toml conflicts - Update ax_hal -> ax_runtime::hal paths in kmod_loader.rs - Remove dw_apb_uart (not in workspace dependencies) * fix(starry-kernel): add cfg(ebpf) gate for perf_event module and trigger perf_event.rs references crate::ebpf::run_bpf_prog which is only available under the ebpf feature. Add cfg gates to prevent compilation failure when ebpf feature is disabled. * ci: rebase onto latest dev, resolve Cargo.lock conflict --- Cargo.lock | 487 ++++++++++++------

+//! # Known Limitations +//! +//! - `resolve_symbol` is a stub returning `None`; full implementation +//! requires PR #837 (kallsyms) to be merged. +//! - `delete_module` and `finit_module` are syscall stubs. +//! - Loaded modules are kept alive via `mem::forget`; future `delete_module` +//! will need a global registry to recover and free resources. + +use alloc::{ + alloc::{Layout, alloc, dealloc}, + boxed::Box, +}; + +use ax_memory_addr::{PAGE_SIZE_4K, VirtAddr}; +use kmod_loader::{KernelModuleHelper, SectionMemOps, SectionPerm}; + +static RESOLVE_SYMBOL_WARNED: core::sync::atomic::AtomicBool = + core::sync::atomic::AtomicBool::new(false); + +struct KmodSectionMem { + ptr: *mut u8, + size: usize, + layout: Layout, +} + +impl KmodSectionMem { + fn new(size: usize) -> Option { + let aligned_size = (size + PAGE_SIZE_4K - 1) & !(PAGE_SIZE_4K - 1); + let layout = Layout::from_size_align(aligned_size, PAGE_SIZE_4K).ok()?; + let ptr = unsafe { alloc(layout) }; + if ptr.is_null() { + return None; + } + unsafe { core::ptr::write_bytes(ptr, 0, aligned_size) }; + Some(Self { + ptr, + size: aligned_size, + layout, + }) + } +} + +impl SectionMemOps for KmodSectionMem { + fn as_ptr(&self) -> *const u8 { + self.ptr + } + + fn as_mut_ptr(&mut self) -> *mut u8 { + self.ptr + } + + fn change_perms(&mut self, perms: SectionPerm) -> bool { + let vaddr = VirtAddr::from(self.ptr as usize); + let mut aspace = ax_mm::kernel_aspace().lock(); + let (_, original_flags, _) = match aspace.page_table().query(vaddr) { + Ok(r) => r, + Err(_) => return false, + }; + let mut new_flags = ax_runtime::hal::paging::MappingFlags::empty(); + if perms.contains(SectionPerm::READ) { + new_flags |= ax_runtime::hal::paging::MappingFlags::READ; + } + if perms.contains(SectionPerm::WRITE) { + new_flags |= ax_runtime::hal::paging::MappingFlags::WRITE; + } + if perms.contains(SectionPerm::EXECUTE) { + new_flags |= ax_runtime::hal::paging::MappingFlags::EXECUTE; + } + if aspace.protect(vaddr, self.size, new_flags).is_err() { + return false; + } + for offset in (0..self.size).step_by(PAGE_SIZE_4K) { + ax_runtime::hal::cpu::asm::flush_tlb(Some(vaddr + offset)); + } + if perms.contains(SectionPerm::EXECUTE) { + ax_runtime::hal::cpu::asm::flush_icache_all(); + } + drop(aspace); + let _ = original_flags; + true + } +} + +unsafe impl Send for KmodSectionMem {} +unsafe impl Sync for KmodSectionMem {} + +impl Drop for KmodSectionMem { + fn drop(&mut self) { + if !self.ptr.is_null() { + unsafe { dealloc(self.ptr, self.layout) }; + } + } +} + +struct NullSectionMem; + +impl SectionMemOps for NullSectionMem { + fn as_ptr(&self) -> *const u8 { + core::ptr::null() + } + + fn as_mut_ptr(&mut self) -> *mut u8 { + core::ptr::null_mut() + } + + fn change_perms(&mut self, _perms: SectionPerm) -> bool { + false + } +} + +pub struct StarryKmodHelper; + +impl KernelModuleHelper for StarryKmodHelper { + fn vmalloc(size: usize) -> Box { + match KmodSectionMem::new(size) { + Some(mem) => Box::new(mem), + None => { + warn!("kmod: vmalloc failed for size {size}"); + Box::new(NullSectionMem) + } + } + } + + fn resolve_symbol(_name: &str) -> Option { + if RESOLVE_SYMBOL_WARNED + .compare_exchange( + false, + true, + core::sync::atomic::Ordering::Relaxed, + core::sync::atomic::Ordering::Relaxed, + ) + .is_ok() + { + warn!("kmod: resolve_symbol not yet available (depends on PR #837 kallsyms)"); + } + None + } + + fn flsuh_cache(addr: usize, size: usize) { + #[cfg(target_arch = "aarch64")] + ax_runtime::hal::cpu::asm::clean_dcache_range_to_pou(VirtAddr::from(addr), size); + let _ = (addr, size); + ax_runtime::hal::cpu::asm::flush_icache_all(); + } +} + +#[allow(dead_code)] +pub fn load_module_from_memory( + elf_data: &[u8], + args: &str, +) -> ax_errno::AxResult> { + let loader = kmod_loader::ModuleLoader::::new(elf_data).map_err(|e| { + warn!("kmod: failed to create loader: {e:?}"); + ax_errno::AxError::Io + })?; + let c_args = alloc::ffi::CString::new(args).map_err(|_| ax_errno::AxError::InvalidInput)?; + loader.load_module(c_args).map_err(|e| { + warn!("kmod: failed to load module: {e:?}"); + ax_errno::AxError::Io + }) +} + +pub fn sys_init_module( + elf_ptr: usize, + elf_len: usize, + args_ptr: usize, +) -> ax_errno::AxResult { + if elf_ptr == 0 || elf_len == 0 { + return Err(ax_errno::AxError::InvalidInput); + } + let elf_data = unsafe { core::slice::from_raw_parts(elf_ptr as *const u8, elf_len) }; + let args = if args_ptr != 0 { + unsafe { + let p = args_ptr as *const i8; + let len = (0..).take_while(|&i| *p.add(i) != 0).count(); + core::str::from_utf8(core::slice::from_raw_parts(p as *const u8, len)).unwrap_or("") + } + } else { + "" + }; + let mut owner = load_module_from_memory(elf_data, args)?; + owner.call_init().map_err(|e| { + warn!("kmod: module init failed: {e:?}"); + ax_errno::AxError::Io + })?; + info!("kmod: module loaded and initialized successfully"); + // Intentionally leak the module owner: the loaded module must remain in + // memory for the kernel's lifetime.

区间分配算法组件 -> 版本：`0.1.4` -> 文档依据：当前仓库源码、`Cargo.toml`、`README.md`、`src/lib.rs`、`tests/test.rs`、`virtualization/axdevice/src/device.rs`、`virtualization/axvm/src/vm.rs`、`os/axvisor/src/vmm/hvc.rs` - -`range-alloc-arceos` 的真实定位是一个**泛型连续区间分配器**。它管理的是一个初始范围上的“哪些子区间空闲、哪些子区间已占用”，并提供 best-fit 分配与回收合并逻辑。它不是页分配器，不处理地址映射，不理解设备，不负责对齐策略，更不是完整的内存管理子系统。 - -## 架构设计 - -### 设计定位 - -这个 crate 的问题模型非常明确： - -- 有一个初始区间 `start..end` -- 需要不断从中分配连续子区间 -- 需要在释放时把相邻空闲区间重新合并 -- 希望尽量降低碎片化 - -因此它选择的核心数据结构不是树或位图，而是： - -- 一个有序的 `Vec> free_ranges` - -并把已分配区间看作“初始区间减去空闲区间”的补集。 - -### 1.2 核心数据结构 - -`RangeAllocator` 内部只有两项状态： - -| 字段 | 作用 | -| --- | --- | -| `initial_range` | 整个分配器负责管理的总范围 | -| `free_ranges` | 当前空闲区间表，按起始地址升序排列且互不重叠 | - -这两个不变量非常关键： - -- `free_ranges` 必须有序 -- `free_ranges` 之间不能重叠 - -几乎所有接口都围绕维护这两个不变量展开。 - -### 1.3 分配策略：best-fit - -`allocate_range(length)` 的实现会遍历所有空闲区间，并选择： - -- 能满足请求的最小空闲区间 - -这是一种典型的 best-fit 策略。它的好处是： - -- 优先消耗最贴合请求的空闲块 -- 尽量保留大块连续空间 - -若找不到足够大的单个区间，则返回： - -- `RangeAllocationError { fragmented_free_length }` - -其中 `fragmented_free_length` 表示把所有空闲区间长度加起来后，总共还有多少空闲量。这个字段能帮助调用者区分： - -- 是真的没空间了 -- 还是只是碎片太多，凑不出连续区间 - -### 1.4 回收策略：邻接合并 - -`free_range(range)` 的逻辑重点不在简单插入，而在合并： - -- 如果与左邻接，则与左合并 -- 如果与右邻接，则与右合并 -- 如果左右都邻接，则把三段合成一段 -- 否则在有序位置插入 - -源码中还有断言确保： - -- 释放区间必须位于 `initial_range` 内 -- 区间必须非空 -- 插入后不会与现有空闲区间重叠 - -这意味着： - -- 双重释放或越界释放不是被“静默忽略”，而是会触发断言 - -### 1.5 扩容与观察接口 - -除了分配/回收，这个 crate 还提供了几个非常实用的辅助接口： - -- `grow_to(new_end)`：扩展管理上界 -- `allocated_ranges()`：通过空闲表反推出当前已分配区间 -- `reset()`：恢复到初始全空闲状态 -- `is_empty()`：检查是否尚未分配任何区间 -- `total_available()`：统计所有空闲区间的总长度 - -尤其是 `allocated_ranges()`，说明这个分配器不仅能“给空间”，也适合做状态观察和调试。 - -### 1.6 与 Axvisor 当前实现的真实关系 - -当前仓库里的真实调用链非常清晰： - -1. `axdevice::AxVmDevices` 在 `IVCChannel` 设备配置初始化时，创建 `RangeAllocator` -2. 这个区间的范围来自 IVC 共享内存的 guest physical address 空间 -3. `axvm::VM::alloc_ivc_channel()` 先把请求大小向上对齐到 4K -4. 然后调用 `devices.alloc_ivc_channel()`，最终落到 `RangeAllocator::allocate_range()` -5. `os/axvisor/src/vmm/hvc.rs` 在处理 IVC hypercall 时使用这套分配/回收能力 - -这条链路很重要，因为它清楚地说明了： - -- 对齐是 `axvm` 做的，不是本 crate 做的 -- 地址映射是 `axdevice` / `axvm` / `axvisor` 做的，不是本 crate 做的 -- 本 crate 只是区间分配算法核心 - -## 核心功能 - -### 功能概览 - -- 用初始区间构造分配器 -- 按 best-fit 分配连续区间 -- 回收区间并自动合并相邻空闲块 -- 动态扩展管理范围上界 -- 枚举已分配区间 -- 查询空闲总量与是否为空 - -### 2.2 当前仓库中的典型调用链 - -真实调用链可以概括为： - -`range-alloc-arceos` -> `axdevice::AxVmDevices` -> `axvm::VM::{alloc_ivc_channel, release_ivc_channel}` -> `os/axvisor::vmm::hvc` - -也就是说，它当前主要服务于： - -- Axvisor 的 IVC 共享内存 GPA 区间管理 - -### 边界说明 - -`range-alloc-arceos` 不负责： - -- 地址对齐 -- 物理页分配 -- 页表映射 -- 内存清零 -- 共享内存元数据管理 - -它只是一个**泛型区间分配算法组件**。 - -## 依赖关系 - -### 直接依赖 - -该 crate 没有额外三方依赖，主要依靠： - -- `alloc::vec::Vec` -- `core::ops::Range` - -完成实现。 - -### 主要消费者 - -当前仓库内可确认的直接消费者： - -- `axdevice` - -明确可见的间接链路： - -- `range-alloc-arceos` -> `axdevice` -> `axvm` -> `os/axvisor` - -### 3.3 关系解读 - -| 层级 | 角色 | -| --- | --- | -| `range-alloc-arceos` | 连续区间分配算法 | -| `axdevice` | 为 VM 设备层提供 IVC GPA 区间池 | -| `axvm` | 负责对齐请求并包装返回值 | -| `os/axvisor` | 在 HyperCall 处理中真正消费分配结果 | - -## 开发指南 - -### 4.1 适合什么时候使用 - -适合使用该 crate 的场景是： - -- 资源天然可以表达为一个线性区间 -- 分配单位是“连续范围”而不是单点 -- 希望能观察碎片化情况 -- 对齐策略可以由上层单独处理 - -不适合直接把它当成： - -- 伙伴系统 -- 物理页分配器 -- 完整地址空间管理器 - -### 4.2 维护时的关键注意事项 - -- `free_ranges` 的有序、不重叠不变量必须始终保持 -- `free_range()` 的断言意味着重叠回收会直接失败，不是容错逻辑 -- 若要新增“带对齐分配”接口，应明确这是否属于本 crate 的职责扩张 -- `T` 的 trait bound 是经过精简设计的，不要轻易扩大或改变数值语义 - -### 4.3 与上层系统的职责分工 - -- 大小 4K 对齐：`axvm` -- GPA 空间来源：`axdevice` -- IVC 映射与共享内存语义：`axvisor` -- 连续区间 best-fit 分配/合并：本 crate - -这条分工线非常清楚，文档里不能把它写成“IVC 管理模块”。 - -## 测试 - -### 测试覆盖 - -当前测试已经相对充分： - -- `src/lib.rs` 中有较多单元测试 -- `tests/test.rs` 还有额外集成测试 - -现有测试覆盖了： - -- 基本分配/释放 -- 空间耗尽 -- `grow_to()` -- 中间空洞 -- best-fit 选择 -- 邻接合并 -- 碎片化行为 - -### 5.2 建议补充的测试 - -- double free / 重叠 free 的 `should_panic` 测试 -- 与 `axdevice` / `axvm` 结合的 4K 对齐集成测试 -- 更大整数类型或边界类型参数测试 - -### 5.3 风险点 - -- 如果文档忽略“对齐由上层完成”，调用者很容易误用 -- `free_range()` 的断言语义需要明确，否则回收错误会在运行时直接崩溃 -- best-fit 不是唯一策略，今后若替换策略需要同步评估上层碎片行为 - -## 跨项目定位 - -| 项目 | 位置 | 角色 | 说明 | -| --- | --- | --- | --- | -| ArceOS | 当前仓库未见直接接线 | 通用区间算法组件 | 目前不在 ArceOS 主线路径上 | -| StarryOS | 当前仓库未见直接接线 | 通用区间算法组件 | 尚未看到直接使用 | -| Axvisor | `axdevice` / `axvm` / `hvc` IVC 链路 | IVC GPA 连续区间分配算法 | 当前最明确、最真实的使用场景 | - -## 总结 - -`range-alloc-arceos` 的价值在于把“连续区间 best-fit 分配 + 合并回收”这件事做成了一个独立、泛型、`no_std` 友好的算法组件。当前仓库里它主要服务于 Axvisor 的 IVC GPA 区间管理，但它本身并不理解 IVC、设备或内存映射。理解它时最重要的边界，就是把它看成**区间分配算法**，而不是更高层的资源子系统。 diff --git a/docs/docs/components/layers.md b/docs/docs/components/layers.md index c781aa0ccc..c71560dab7 100644 ---

Remove the alloc feature entirely and make ax-alloc a required dependency. Propagating changes to axfeat to remove the now-unnecessary alloc forwarding from 15 features. Co-authored-by: Claude Opus 4.7 * Remove range-alloc-arceos crate and its associated files (#991) - Deleted LICENSE, LICENSE.APACHE, LICENSE.MIT, README.md, README_CN.md, and src/lib.rs files. - Removed tests and examples related to the range allocator functionality. * Refactor linker scripts and CI configuration (#992) * refactor(linker-scripts): remove unused linker scripts for hello, irq, and smp kernels * refactor(ci): switch clippy and std tests to self-hosted runners * feat(deps): update spin to version 0.12.0 and bump other dependencies * feat: remove riscv64-qemu-virt references and update platform support in configuration --------- Co-authored-by: Claude Opus 4.7 Co-authored-by: ZCShou <72115@163.com> --- Cargo.lock | 388 +++++++++-------- .../build-aarch64-unknown-none-softfloat.toml | 4 +- .../build-aarch64-unknown-none-softfloat.toml | 2 -

Implement the Slice 1 minimum cgroup2 root filesystem: explicit cgroup2 mount support, root cgroup.procs, empty cgroup.controllers, empty cgroup.subtree_control, and errno-preserving write failures for unsupported operations. Keep cgroup v1 mounts unsupported with ENODEV and avoid hierarchy, controller, procfs cgroup, and clone cgroup semantics. --- os/StarryOS/kernel/src/cgroup/mod.rs | 39 ++++ os/StarryOS/kernel/src/lib.rs | 1 + os/StarryOS/kernel/src/pseudofs/cgroup.rs | 84 +++++++++ os/StarryOS/kernel/src/pseudofs/mod.rs | 1 + os/StarryOS/kernel/src/syscall/fs/mount.rs | 8 + .../qemu-smp1/cgroup-basic/c/CMakeLists.txt | 10 ++ .../qemu-smp1/cgroup-basic/c/src/main.c | 166 ++++++++++++++++++ .../qemu-smp1/cgroup-basic/qemu-aarch64.toml | 22 +++ .../cgroup-basic/qemu-loongarch64.toml | 24 +++ .../qemu-smp1/cgroup-basic/qemu-riscv64.toml | 22 +++ .../qemu-smp1/cgroup-basic/qemu-x86_64.toml | 14 ++ 11 files changed, 391 insertions(+) create mode 100644 os/StarryOS/kernel/src/cgroup/mod.rs create mode 100644 os/StarryOS/kernel/src/pseudofs/cgroup.rs create mode 100644 test-suit/starryos/normal/qemu-smp1/cgroup-basic/c/CMakeLists.txt create mode 100644 test-suit/starryos/normal/qemu-smp1/cgroup-basic/c/src/main.c create mode 100644 test-suit/starryos/normal/qemu-smp1/cgroup-basic/qemu-aarch64.toml create mode 100644 test-suit/starryos/normal/qemu-smp1/cgroup-basic/qemu-loongarch64.toml create mode 100644 test-suit/starryos/normal/qemu-smp1/cgroup-basic/qemu-riscv64.toml create mode 100644 test-suit/starryos/normal/qemu-smp1/cgroup-basic/qemu-x86_64.toml diff --git a/os/StarryOS/kernel/src/cgroup/mod.rs b/os/StarryOS/kernel/src/cgroup/mod.rs new file mode 100644 index 0000000000..9b5fd77275 --- /dev/null +++ b/os/StarryOS/kernel/src/cgroup/mod.rs @@ -0,0 +1,39 @@ +use alloc::{string::String, vec::Vec}; +use core::fmt::Write; + +use ax_errno::{AxError, AxResult, LinuxError}; + +/// Returns the process list for the root cgroup. +pub fn root_procs_text() -> String { + let mut pids: Vec<_> = crate::task::processes() + .into_iter() + .map(|proc_data| proc_data.proc.pid()) + .collect(); + pids.sort_unstable(); + + let mut text = String::new(); + for pid in pids { + let _ = writeln!(text, "{pid}"); + } + text +} + +/// Returns the controllers visible at the root cgroup. +pub fn root_controllers_text() -> &'static str { + "" +} + +/// Returns enabled subtree controllers at the root cgroup. +pub fn root_subtree_control_text() -> &'static str { + "" +} + +/// Writes to cgroup.procs are not implemented in this slice. +pub fn write_root_procs(_data: &[u8]) -> AxResult<()> { + Err(AxError::from(LinuxError::EOPNOTSUPP)) +} + +/// Writes to cgroup.subtree_control cannot enable unavailable controllers. +pub fn write_root_subtree_control(_data: &[u8]) -> AxResult<()> { + Err(AxError::from(LinuxError::EINVAL)) +} diff --git a/os/StarryOS/kernel/src/lib.rs b/os/StarryOS/kernel/src/lib.rs index 7010d5b688..cf4324314a 100644 --- a/os/StarryOS/kernel/src/lib.rs +++ b/os/StarryOS/kernel/src/lib.rs @@ -17,6 +17,7 @@ pub mod dyn_debug; // Re-export debug macros for use in other modules.

TLSF now uses rlsf directly as a single-level allocator. buddy-slab remains unchanged. - Remove ax-allocator dependency, add rlsf directly - Remove slab/buddy/page-alloc-4g/page-alloc-64g features - tlsf and buddy-slab are mutually exclusive, neither enabled by default - Add build.rs for cfg(tlsf)/cfg(buddy_slab) generation - Add stub_impl.rs with unimplemented!() when no backend is selected - Clean up downstream Cargo.toml feature propagation * fix(starry): separate allocator feature selection from static features Remove hardcoded `alloc-tlsf` from starry-kernel's static ax-feat features to avoid conflicting with buddy-slab. Add `tlsf` feature to starry-kernel and starryos crates. Add `starryos/tlsf` to all non-buddy-slab StarryOS test configurations. * Refactor memory allocator configuration and implementation - Updated `Cargo.toml` files to remove unused allocator features and streamline dependencies. - Replaced `alloc-slab` and `alloc-buddy` with `alloc-tlsf` in the kernel and API configurations. - Removed the default implementation of the memory allocator and introduced a stub implementation for cases where no backend is enabled. - Implemented a TLSF (Two-Level Segregate Fit) memory allocator using the `rlsf` crate, providing efficient memory management. - Added a build script to enforce mutually exclusive feature selection between `tlsf` and `buddy-slab`. - Cleaned up the allocator's API to ensure proper usage statistics tracking and memory management. * fix(ax-alloc): select allocator backend from platforms * fix(starryos): give x86 dhcp test enough memory * refactor: remove optional dependency on axklib for paging feature --- Cargo.lock | 9 +- components/axklib/Cargo.toml | 6 + drivers/ax-driver/Cargo.toml | 2 +- os/StarryOS/kernel/Cargo.toml | 6 +- os/StarryOS/starryos/Cargo.toml | 1 -

feat(starry-kernel): x86_64 ptrace register r/w and PTRACE_SINGLESTEP support MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 补齐 x86_64 ptrace 主干功能： ## Kernel changes (os/StarryOS/kernel) ### ptrace.rs: x86_64 register read/write + singlestep - 新增 `X8664UserRegs` 结构体 (repr(C))，对应 Linux `user_regs_struct`，含 r15..rsp/ss/fs_base/gs_base 全部 27 个字段 - 实现 `From for X8664UserRegs` 和 `write_to()` - 补齐 x86_64 上之前缺失的 ptrace opcode： GETREGS / SETREGS / GETREGSET(NT_PRSTATUS) / SETREGSET(NT_PRSTATUS) / GETSIGINFO / SETSIGINFO - 将 `ptrace_getregset_prstatus` 中 `regs` 局部变量从内部 block 提升到 函数级作用域，修复 reg_bytes slice 的 use-after-free bug（regs 出 block 后被栈复用覆盖，导致用户态读到随机值，表现为 RSP=0x1） - 新增 `ptrace_setup_singlestep` for x86_64：设置 RFLAGS 的 TF (bit 8) 触发 CPU 单步执行 ### user.rs: SINGLESTEP + #DB 异常路由 - 为 x86_64 添加 singlestep setup 调用（之前仅 riscv64） - 新增 `ExceptionKind::Debug` 处理分支：命中 traced task 的 #DB 异常时，清除 TF 并调用 ptrace_stop_current(SIGTRAP) - Intel SDM 规定 CPU 在交付 TF 诱导的 #DB 时会清除 pushed RFLAGS 中的 TF，但 QEMU 不完全遵守，故显式清除防止 resume 后再次单步 ## Test cases (test-suit/starryos/normal/qemu-smp1) | 测试 | 验证内容 | |------|----------| | test-ptrace-x86-regs | TRACEME ->
