- 保护集合 = 当前运行内核 release ∪ 最新 2 个内核 release ∪ proxmox-boot-tool 已固定的内核 - 版本判定改为以 kernel release 为单位，signed / unsigned 视为同一内核版本 - 无法解析包名或运行内核无法对应到已安装包时放弃自动清理（fail-safe） - 删除前逐条列出待删内核包；部分失败不再谎报「旧内核清理完成」 - 新增 tests/kernel-cleanup-test.sh（21 项，纯逻辑 + mock）
- 上游 2026.09.16 起 Xe_LP 平台不再默认启用 CCS0，新增按需配置： 仅 i915 路线写入 i915.xelp_enable_ccs=1，不叠加 xe 参数 - DKMS 版本询问前移到 GRUB 写入之前，并按上游 release 声明的内核范围核对兼容性 - 识别核显平台与引导方式；systemd-boot 主机明确提示 GRUB 参数不生效并给出手动步骤 - CCS0 参数归属标记：仅清理本工具写入的参数，切换 GVT-g / 移除配置时不误删用户自建参数 - grub_* 写入失败不再谎报成功；SR-IOV 配置仅在参数确有变化时执行 update-grub - 核显虚拟化状态检查新增 CCS0 是否真正生效的校验 - 新增 tests/intel-sriov-ccs-test.sh（66 项）
Reviewer's GuideThis release hardens kernel cleanup with fail-safe, release-aware selection and adds a compatibility-driven Intel SR-IOV CCS0 workflow, while improving GRUB write error handling, bootloader guidance, parameter ownership, and local regression coverage.

**Manual boot instructions risk root arguments**
When a systemd-boot user follows the displayed list by replacing the existing cmdline contents, the systemd-boot instructions list only SR-IOV parameters for `/etc/kernel/cmdline` and do not say to preserve the existing line. Replacing the file with the displayed list drops required arguments such as `root=`, and the host can fail to boot.
Explicitly instruct users to append the options to the existing single-line cmdline and preserve all existing boot-critical arguments.

**Scheduled kernel can be purged**
When a one-time next-boot pin targets an older kernel and cleanup runs before that boot, `kernel_pinned_releases` checks `/etc/kernel/next-boot-pin` instead of Proxmox’s `/etc/kernel/next-boot`, so it misses the pinned release. `kernel_cleanup_select_removals` can then select its package for removal before the scheduled boot.
Read the one-time next-boot pin from `/etc/kernel/next-boot`.

**Existing CCS0 setting is lost**
When the user enables CCS0 while GRUB already contains `i915.xelp_enable_ccs`, `grub_add_param` replaces the existing value, and `sriov_mark_ccs_param_owned` records the replacement without preserving the prior setting. Later cleanup deletes the key, losing the user’s configuration.
Preserve and restore any pre-existing `i915.xelp_enable_ccs` value instead of claiming it as tool-owned.

**CCS0 ownership becomes inconsistent**
When writing the ownership marker fails, removing the GRUB parameter fails, or the process stops between the GRUB edit and marker update, `sriov_mark_ccs_param_owned` suppresses marker-write errors, while `sriov_remove_ccs_param_if_owned` can clear the marker and return success after `grub_remove_param` fails. The parameter and marker can therefore disagree, so later cleanup treats a tool-written CCS0 setting as user-owned and leaves it active without reporting the failure.
Make marker updates and GRUB edits report failures and preserve or recover ownership state unless the corresponding parameter change succeeds.

**systemd-boot setup stops early**
When the host uses systemd-boot and `/etc/default/grub` is absent, unwritable, or lacks `GRUB_CMDLINE_LINUX_DEFAULT`, the setup still treats GRUB parameter edits as fatal, and the failure check returns before driver and module configuration. This contradicts the prompt that offers to continue with manual kernel-parameter setup.
For systemd-boot hosts, skip fatal GRUB edits and continue with driver and module configuration as the prompt promises.

</code_context>
<issue_to_address>
**Concurrent edits drop GRUB parameters**
When two tool processes concurrently modify `/etc/default/grub` (for example, one configures SR-IOV while another edits IOMMU parameters), both `grub_add_param`/`grub_remove_param` callers read the same command line before either writes; the later `sed -i` replaces the earlier caller’s update. Concurrent GPU or security configuration operations therefore silently lose kernel parameters, which can leave the next boot misconfigured.
Serialize GRUB read-modify-write operations with a shared lock and perform each mutation against the latest file contents while holding it.
Also at `lib/core.sh:448`.

**Held running kernel skips cleanup**
When the running kernel package is held and appears as `hi` in dpkg, `remove_old_kernels` requests only `ii` packages, so the held running kernel is absent from the installed list. `kernel_cleanup_select_removals` cannot match the current release and fails safe, skipping cleanup of older kernels.

Needs a human reviewer. 8 findings to address first, and this changes production boot configuration and can permanently remove installed kernel packages; a wrong selection or GRUB update could cause a reboot outage, and reverting the code would not restore deleted packages or undo that outage. The consequences are bounded and potentially repairable by reinstalling kernels and restoring boot configuration.
