2019-01-09cpu/intel/common: Fix generated exception if not supported VMXElyes HAOUAS
Reading rdmsr(IA32_FEATURE_CONTROL) in function set_feature_ctrl_lock() will generate an exception if the CPU do not support this MSR. Tested on pentium4 (CPUID F65).

2019-01-05cpu/intel/common: improve debug outputMatt DeVillier
currently, if the IA32_FEATURE_CONTROL lock bit is already set, VMX status isn't reported. Adjust debug output to provide more useful infomation on both VMX and lock bit statuses. Test: build/boot google/chell, observe useful output in cbmem log regardless of lock bit status.

2018-12-20cpu/intel/common: decouple IA32_FEATURE_CONTROL lock from set_vmx()Matt DeVillier
Newer CPUs/SoCs need to configure other features via the IA32_FEATURE_CONTROL msr, such as SGX, which cannot be done if the msr is already locked. Create separate functions for setting the vmx flag and lock bit, and rename existing function to indicate that the lock bit will be set in addition to vmx flag (per Kconfig). This will allow Skylake/Kabylake (and others?) to use the common VMX code without breaking SGX, while ensuring no change in functionality to existing platforms which current set both together. Test: build/boot each affected platform, ensure no change in functionality Change-Id: Iee772fe87306b4729ca012cef8640d3858e2cb06 Signed-off-by: Matt DeVillier <matt.devillier@gmail.com> Reviewed-on: https://review.coreboot.org/c/30229 Reviewed-by: Nico Huber <nico.h@gmx.de> Reviewed-by: David Guckian Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
2018-12-13cpuid: Add helper function for cpuid(1) functionsSubrata Banik
This patch introduces 3 helper function for cpuid(1) : 1. cpu_get_cpuid() -> to get processor id (from cpuid.eax) 2. cpu_get_feature_flags_ecx -> to get processor feature flag (from cpuid.ecx) 3. cpu_get_feature_flags_edx -> to get processor feature flag (from cpuid.edx) Above 3 helper functions are targeted to replace majority of cpuid(1) references.

2018-01-17cpu/intel/speedstep: Fix the PNOT ACPI methodArthur Heymans
The PNOT method never notifies the CPU to update it's _CST methods due to reliance on inexisting variable (PDCx). Add a method in the speedstep ssdt generator to notify all available CPU nodes and hook this up in this file. The cpu.asl file is moved to cpu/intel/speedstep/acpi since it now relies on code generated in the speedstep ssdt generator. CPUs not using the speedstep code never included this PNOT method so this is a logical place for this code to be.

2015-10-23cpu/intel: Move Power notification ASL code into `common/acpi`Paul Menzel
Commit 24813c14 (i945: Consolidate acpi/platform.asl) creates the file in the directory `src/cpu/intel/model_6dx/acpi`, although the devices can also use different Intel CPU models like, for example, `intel/model_6ex` on the Lenovo T60. Therefore move the file to the directory `src/cpu/intel/common/acpi` so that other devices, like Intel GM45 based devices, can also include it.
