Subject: [PATCH 0/2] x86/microcode/amd: early loading fixes
Date: Wed, 5 Jun 2013 15:13:54 -0500 [thread overview]
Message-ID: <1370463236-2115-1-git-send-email-jacob.shin@amd.com> (raw)
This patchset addreses two problems with early loading on AMD.
First, feedback from Yinghai that find_ucode_in_initrd() should be
marked __init:
https://lkml.org/lkml/2013/6/4/695
And second, feedback from Henrique that Intel early loading supports
multiple microcode firmware concatenated together, whereas the current
AMD implementation lacks this support:
https://lkml.org/lkml/2013/5/31/4
Jacob Shin (2):
x86/microcode/amd: make find_ucode_in_initrd() __init
x86/microcode/amd: allow multiple families' bin files appended
together
