2020-04-04src/cpu: Use SPDX for GPL-2.0-only filesAngel Pons
Done with sed and God Lines. Only done for C-like code for now. Change-Id: I2adf28d805fe248d55a9514f74c38280c0ad9a78 Signed-off-by: Angel Pons <th3fanbus@gmail.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/40049 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: HAOUAS Elyes <ehaouas@noos.fr>
2019-10-01cpu/intel/common: Move intel_ht_sibling() to common folderPatrick Rudolph
Make intel_ht_sibling() available on all platforms. Will be used in MP init to only write "Core" MSRs from one thread on HyperThreading enabled platforms, to prevent race conditions and resulting #GP if MSRs are written twice or are already locked.

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>
2018-08-20cpu/intel/common: add function to init cppc_configMatt Delco
This change adds a method to init a cppc_config structure in a way that should ideally work across Intel processors that support EIST.

2016-12-27cpu/intel/common: Add/Use common function to set virtualizationMatt DeVillier
Migrate duplicated enable_vmx() method from multiple CPUs to common folder. Add common virtualization option for CPUs which support it. Note that this changes the default to enable virtualization on CPUs that support it.
