linux-stable.git/arch/x86/include/uapi/asm/bootparam.h, branch v3.8 Linux kernel stable tree x86, boot: Define the 2.12 bzImage boot protocol 2013-01-27T23:56:37+00:00 H. Peter Anvin hpa@linux.intel.com 2013-01-27T18:43:28+00:00 09c205afde70c15f20ca76ba0a57409dad175fd0 Define the 2.12 bzImage boot protocol: add xloadflags and additional fields to allow the command line, initramfs and struct boot_params to live above the 4 GiB mark. The xloadflags now communicates if this is a 64-bit kernel with the legacy 64-bit entry point and which of the EFI handover entry points are supported. Avoid adding new read flags to loadflags because of claimed bootloaders testing the whole byte for == 1 to determine bzImageness at least until the issue can be researched further. This is based on patches by Yinghai Lu and David Woodhouse.

Define the 2.12 bzImage boot protocol: add xloadflags and additional
fields to allow the command line, initramfs and struct boot_params to
live above the 4 GiB mark.

The xloadflags now communicates if this is a 64-bit kernel with the
legacy 64-bit entry point and which of the EFI handover entry points
are supported.

Avoid adding new read flags to loadflags because of claimed
bootloaders testing the whole byte for == 1 to determine bzImageness
at least until the issue can be researched further.

This is based on patches by Yinghai Lu and David Woodhouse.
