x86, efi: Add EFI boot stub documentation

2012-06-01T16:11:41+00:00

Since we can't expect every user to read the EFI boot stub code it seems prudent to have a couple of paragraphs explaining what it is and how it works. The "initrd=" option in particular is tricky because it only understands absolute EFI-style paths (backslashes as directory separators), and until now this hasn't been documented anywhere. This has tripped up a couple of users.

Commit 3ae36655b97a03fa1decf72f04078ef945647c1a (x86-64: Rework vsyscall emulation and add vsyscall= parameter) removed the special use of the 0xcc IDT vector. Remove it from Documentation/x86/entry_64.txt also.

x86, doc only: Correct real-mode kernel header offset for init_size

2011-07-13T03:39:11+00:00

The real-mode kernel header init_size field is located at 0x260 per the field listing in th e"REAL-MODE KERNEL HEADER" section. It is listed as 0x25c in the "DETAILS OF HEADER FIELDS" section, which overlaps with pref_address. Correct the details listing to 0x260.

x86: support XZ-compressed kernel

2011-01-13T16:03:25+00:00

This integrates the XZ decompression code to the x86 pre-boot code. mkpiggy.c is updated to reserve about 32 KiB more buffer safety margin for kernel decompression. It is done unconditionally for all decompressors to keep the code simpler. The XZ decompressor needs around 30 KiB of heap, so the heap size is increased to 32 KiB on both x86-32 and x86-64. Documentation/x86/boot.txt is updated to list the XZ magic number. With the x86 BCJ filter in XZ, XZ-compressed x86 kernel tends to be a few percent smaller than the equivalent LZMA-compressed kernel. Signed-off-by: Lasse Collin Cc: "H.
