x86: moved microcode.c to microcode_intel.c

2008-09-23T10:21:42+00:00

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. Signed-off-by: Dmitry Adamushko Cc: "Peter Oruba" Signed-off-by: Ingo Molnar

x86, microcode rework, v2

2008-09-12T10:20:27+00:00

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

x86-microcode: generic interface refactoring

2008-08-20T10:18:57+00:00

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 Signed-off-by: Ingo Molnar

x86: major refactoring

2008-07-28T17:57:57+00:00

Refactored code by introducing a two-module solution. There is one general module in which vendor specific modules can hook into. However, that is exclusive, there is only one vendor specific module allowed at a time. A CPU vendor check makes sure only the correct module for the underlying system gets called. Functinally in terms of patch loading itself there are no changes. This refactoring provides a basis for future implementations of other vendors' patch loaders.
