* | x86, microcode_intel_early: Mark apply_microcode_early() as cpuinit | H. Peter Anvin | 2013-03-21 |
| | | | | | | | | | Add missing __cpuinit annotation to apply_microcode_early(). Reported-by: Shaun Ruffell <sruffell@digium.com> Cc: Fenghua Yu <fenghua.yu@intel.com> Link: http://lkml.kernel.org/r/20130320170310.GA23362@digium.com Signed-off-by: H. Peter Anvin <hpa@linux.intel.com> | ||
* | x86-32, microcode_intel_early: Fix crash with CONFIG_DEBUG_VIRTUAL | Fenghua Yu | 2013-03-19 |
| | | | | | | | | | | | | | | | In 32-bit, __pa_symbol() in CONFIG_DEBUG_VIRTUAL accesses kernel data (e.g. max_low_pfn) that not only hasn't been setup yet in such early boot phase, but since we are in linear mode, cannot even be detected as uninitialized. Thus, use __pa_nodebug() rather than __pa_symbol() to get a global symbol's physical address.

* | x86/microcode_intel_early.c: Early update ucode on Intel's CPU | Fenghua Yu | 2013-01-31 |
Implementation of early update ucode on Intel's CPU. load_ucode_intel_bsp() scans ucode in initrd image file which is a cpio format ucode followed by ordinary initrd image file. The binary ucode file is stored in kernel/x86/microcode/GenuineIntel.bin in the cpio data. All ucode patches with the same model as BSP are saved in memory. A matching ucode patch is updated on BSP. load_ucode_intel_ap() reads saved ucoded patches and updates ucode on AP.
