* x86: fix warning in arch/x86/kernel/microcode_amd.cIngo Molnar2008-12-18
| | | | | | | | | | | | | this warning: arch/x86/kernel/microcode_amd.c: In function ‘apply_microcode_amd’: arch/x86/kernel/microcode_amd.c:163: warning: cast from pointer to integer of different size arch/x86/kernel/microcode_amd.c:163: warning: cast from pointer to integer of different size triggers because we want to pass the address to the microcode MSR, which is 64-bit even on 32-bit. Cast it explicitly to express this. Signed-off-by: Ingo Molnar <mingo@elte.hu>

* x86: microcode_amd: remove (wrong) chipset deivce ID checksAndreas Herrmann2008-12-16
| | | | | | | | | | | | | Impact: remove dead/incorrect code Currently there is no chipset specific ucode. The checks are incorrect anyway (e.g. pci device IDs are 16 bit and not 8 bit). Thus I remove the stuff for the time being and will reintroduce it if it's foreseeable that it is really needed.

* x86, microcode_amd: cleanup, mark request_microcode_user() as unsupportedDmitry Adamushko2008-09-24
| | | | | | | | | | | | | (1) mark mc_size in generic_load_microcode() as unitialized_var to avoid gcc's (false) warning; (2) mark request_microcode_user() as unsupported. The required changes can be added later. Note, we don't break any user-space interfaces here, as there were no kernels with support for AMD-specific ucode update yet. The ucode has to be updated via 'firmware'. Signed-off-by: Dmitry Adamushko <dmitry.adamushko@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

| | | | | | | | | | | Renaming based on patch from Dmitry Adamushko. Made code more readable by renaming define and variables related to microcode _container_file_ header to make it distinguishable from microcode _patch_ header.

* x86: moved microcode.c to microcode_intel.cDmitry Adamushko2008-09-23
| | | | | | | | | | | | Combine both generic and arch-specific parts of microcode into a single module (arch-specific parts are config-dependent). Also while we are at it, move arch-specific parts from microcode.h into their respective arch-specific .c files.

* x86, microcode rework, v2Dmitry Adamushko2008-09-12
| | | | | | | | | | | this is a rework of the microcode splitup in tip/x86/microcode (1) I think this new interface is cleaner (look at the changes in 'struct microcode_ops' in microcode.h); (2) it's -64 lines of code; Signed-off-by: Ingo Molnar <mingo@elte.hu>

* x86-microcode: generic interface refactoringDmitry Adamushko2008-08-20
| | | | | | | | | | | | | | | | | | This is the 1st patch in the series. Here the aim was to avoid any significant changes, logically-wise. So it's mainly about generic interface refactoring: e.g. make microcode_{intel,amd}.c more about arch-specific details and less about policies like make-sure-we-run-on-a-target-cpu (no more set_cpus_allowed_ptr() here) and generic synchronization (no more microcode_mutex here). All in all, more line have been deleted than added. 4 files changed, 145 insertions(+), 198 deletions(-) Signed-off-by: Dmitry Adamushko <dmitry.adamushko@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

* x86: AMD microcode patch loading supportPeter Oruba2008-07-28
This patch introduces microcode patch loading for AMD processors. It is based on previous corresponding work for Intel processors. It hooks into the general patch loading module. Main difference is that a container file format is used to hold all patch data for multiple processors as well as an equivalent CPU table, which comes seperately, as opposed to Intel's microcode patching solution. Kconfig and Makefile have been changed provice config and build option for new source file.
