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>
2018-11-16soc/intel/braswell: add vmx support via CPU_INTEL_COMMONMatt DeVillier
Braswell allready supported vmx, but offered no mechanism to unset it, nor to set the lock bit required for Windows to recognize virtualization. Enable this functionality by adding CPU_INTEL_COMMON config. Test: build/boot Windows 10 on Braswell ChromeOS device, verify Windows shows virtualization as enabled.

2017-09-11cpu/x86/mp_init: remove adjust_cpu_apic_entry()Aaron Durbin
The original purpose of adjust_cpu_apic_entry() was to set up an APIC map. That map was effectively only used for mapping *default* APIC id to CPU number in the SMM handler. The normal AP startup path didn't need this mapping because it was whoever won the race got the next cpu number. Instead of statically calculating (and wrong) just initialize the default APIC id map when the APs come online. Once the APs are online the SMM handler is loaded and the mapping is utilized.

2015-08-29intel/braswell: allow dirty cache line evictions for SMRAM to stickChiranjeevi Rapolu
The BUNIT controls the policy for read/write access to physical memory. For the SMRAM range the policy was not allowing dirty evictions to the SMRAM when the core causing the eviction was not in SMM mode. This could happen when the SMM handler dirtied a line and then RSM'd back into non-SMM mode. The cache line was dirtied while in SMM mode, but when that particular cache line was evicted it would be silently dropped. Fix this by allowing the BUNIT to honor writes to the SMRAM range while the evicting core is not in SMM mode. The core SMRR msr provides the mechanism for disallowing general access to the SMRAM region while it is not in SMM mode.
