x86/microcode/amd: Tone down printk(), don't treat a missing firmware file as an error

2014-01-03T04:33:20Z

commit 11f918d3e2d3861b6931e97b3aa778e4984935aa upstream. Do it the same way as done in microcode_intel.c: use pr_debug() for missing firmware files. There seem to be CPUs out there for which no microcode update has been submitted to kernel-firmware repo yet resulting in scary sounding error messages in dmesg: microcode: failed to load file amd-ucode/microcode_amd_fam16h.bin Signed-off-by: Thomas Renninger Acked-by: Borislav Petkov Link: http://lkml.kernel.org/r/1384274383-43510-1-git-send-email-trenn@suse.de Signed-off-by: Ingo Molnar Signed-off-by: Ben Hutchings

x86, microcode, AMD: Add support for family 16h processors

2012-12-06T11:20:31Z

commit 36c46ca4f322a7bf89aad5462a3a1f61713edce7 upstream. Add valid patch size for family 16h processors.

x86/microcode_amd: Add support for CPU family specific container files

2012-02-03T17:21:38Z

commit 5b68edc91cdc972c46f76f85eded7ffddc3ff5c2 upstream. We've decided to provide CPU family specific container files (starting with CPU family 15h). E.g. for family 15h we have to load microcode_amd_fam15h.bin instead of microcode_amd.bin Rationale is that starting with family 15h patch size is larger than 2KB which was hard coded as maximum patch size in various microcode loaders (not just Linux). Container files which include patches larger than 2KB cause different kinds of trouble with such old patch loaders. Thus we have to ensure that the default container file provides only patches with size less than 2KB.

x86, microcode, AMD: Add microcode revision to /proc/cpuinfo

2011-10-19T14:07:30Z

Enable microcode revision output for AMD after 506ed6b53e00 ("x86, intel: Output microcode revision in /proc/cpuinfo") did it for Intel. Signed-off-by: Borislav Petkov

x86, microcode, AMD: Fix section header size check

2011-06-16T15:23:54Z

The ucode size check has to take the section header size into account too when sanity checking the section length. Shorten and clarify define names, while at it. Caught-by: Ben Hutchings Link: http://lkml.kernel.org/r/1302752223.5282.674.camel@localhost Signed-off-by: Borislav Petkov

x86, microcode, AMD: Correct buf references

Both the equivalence table and the microcode patch types are u32. Access them properly through the buf-ptr. Signed-off-by: Borislav Petkov

x86, microcode, AMD: Fix signedness bug in generic_load_microcode()

2011-02-20T13:01:32Z

install_equiv_cpu_table() returns type int. It uses negative error codes so using an unsigned type breaks the error handling.

x86, microcode, AMD: Extend ucode size verification

2011-02-10T11:24:03Z

The different families have a different max size for the ucode patch, adjust size checking to the family we're running on. Also, do not vzalloc the max size of the ucode but only the actual size that is passed on from the firmware loader. Signed-off-by: Borislav Petkov

x86, microcode, AMD: Remove unneeded memset call

2011-02-09T15:05:35Z

collect_cpu_info_amd() clears its csig arg but this is done in the microcode_core's collect_cpu_info() by clearing the embedding struct ucode_cpu_info. Drop it. Signed-off-by: Borislav Petkov Acked-by: Andreas Herrmann
