2023-10-20	cpu/intel/common: Define build time physical address reserved bits	Jeremy Compostella
	According the Intel Software Developer Manual, CPUID.80000008H:EAX[15:8] reports the physical-address width supported by the processor. Unfortunately, it does not necessarily reflect the physical-address space the system can actulally use as some of those bits can be reserved for internal hardware use. It is critical for coreboot to know the actual physical address size. Overestimating this size can lead to device resource overlaps due to the hardware ignoring upper reserved bits. On rex for instance, it creates some reboot hangs due to an overlap between thunderbolt and Input Output Manager (IOM) address space. As some SoCs, such as Meteor Lake, have physical address reserved bits which cannot be probed at runtime, this commit introduces `CPU_INTEL_COMMON_RESERVED_PHYS_ADDR_BITS' Kconfig to set the number of physical address reserved bits at compilation time for those SoCs. A runtime detection by hardware probing will be attempted if the value is 0 (default).

2023-09-29	arch/x86/Kconfig: introduce RESERVED_PHYSICAL_ADDRESS_BITS_SUPPORT	Felix Held
	Since also some AMD CPUs have reserved physical address bits that can't be used as normal address bits, introduce the RESERVED_PHYSICAL_ADDRESS_BITS_SUPPORT Kconfig option which gets selected by CPU_INTEL_COMMON, and use the new common option to configure if the specific SoC/CPU code implements get_reserved_phys_addr_bits or if the default of this returning 0 is used instead.

2020-11-22	cpu/intel/common: Fill cpu voltage in SMBIOS tables	Patrick Rudolph
	Introduce a weak function to let the platform code provide the processor voltage in 100mV units. Implement the function on Intel platforms using the MSR_PERF_STATUS msr. On other platforms the processor voltage still reads as unknown. Tested on Intel CFL. The CPU voltage is correctly advertised.

2018-12-20	cpu/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>
