x86/boot/Documentation: Fix htmldocs build warning due to malformed table in boot.rst

2025-12-10T07:34:38Z

Sphinx reports htmldocs warnings: Documentation/arch/x86/boot.rst:437: ERROR: Malformed table. Text in column margin in table line 2. The table header defined the first column width as 2 characters ("=="), which is too narrow for entries like "0x10" and "0x13". This caused the text to spill into the margin, triggering a docutils parsing failure. Fix it by extending the first column of assigned boot loader ID to 4 characters ("====") to fit the widest entries.

x86/boot/Documentation: Prefix hexadecimal literals with 0x

2025-12-03T17:49:09Z

The x86 bootloader ID specification text uses hexadecimal values without a 0x prefix: D kexec-tools E Extended (see ext_loader_type) F Special (0xFF = undefined) 10 Reserved 11 Minimal Linux Bootloader 12 OVMF UEFI virtualization stack 13 barebox Which beyond the ambiguity of '13' in isolation, also made me fail a grep -wi '0xd' when I was looking for the kexec bootloader ID definition and caused quite a bit of head-scratching before I found out why it didn't show up. Furthermore, the actual explanatory text uses the 0x prefix: For boot loader IDs above T = 0xD, write T = 0xE to this field and write the extended ID minus 0x10 to the ext_loader_type field. Similarly, the ext_loader_ver field can be used to provide more than four bits for the bootloader version. So make it all both unambiguous, easy to grep and consistent across the entire documentation by prefixing the IDs with 0x. Signed-off-by: Ingo Molnar Cc: "H.

x86/boot/Documentation: Spell 'ID' consistently

Documentation/x86: explain LINUX_EFI_INITRD_MEDIA_GUID

2025-10-14T13:53:40Z

Since the Handover Protocol was deprecated, the recommended approach is to provide an initrd using a UEFI boot service with the LINUX_EFI_INITRD_MEDIA_GUID device path. Documentation for the new approach has been no more than an admonition with a link to an existing implementation. Provide a short explanation of this functionality, to ease future implementations without having to reverse engineer existing ones.

Pull x86 TDX updates from Dave Hansen: "The biggest change here is making TDX and kexec play nicely together. Before this, the memory encryption hardware (which doesn't respect cache coherency) could write back old cachelines on top of data in the new kernel, so kexec and TDX were made mutually exclusive. This removes the limitation. There is also some work to tighten up a hardware bug workaround and some MAINTAINERS updates. - Make TDX and kexec work together - Skip TDX bug workaround when the bug is not present - Update maintainers entries" * tag 'x86_tdx_for_6.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/virt/tdx: Use precalculated TDVPR page physical address KVM/TDX: Explicitly do WBINVD when no more TDX SEAMCALLs x86/virt/tdx: Update the kexec section in the TDX documentation x86/virt/tdx: Remove the !KEXEC_CORE dependency x86/kexec: Disable kexec/kdump on platforms with TDX partial write erratum x86/virt/tdx: Mark memory cache state incoherent when making SEAMCALL x86/sme: Use percpu boolean to control WBINVD during kexec x86/kexec: Consolidate relocate_kernel() function parameters x86/tdx: Skip clearing reclaimed pages unless X86_BUG_TDX_PW_MCE is present x86/tdx: Tidy reset_pamt functions x86/tdx: Eliminate duplicate code in tdx_clear_page() MAINTAINERS: Add KVM mail list to the TDX entry MAINTAINERS: Add Rick Edgecombe as a TDX reviewer MAINTAINERS: Update the file list in the TDX entry.
