ACPI 5.0 defines a method _CPC for "Continuous Performance Control" (CPPC).
Linux has a driver that enables features like speed shift without
consulting ACPI. Other OSes instead rely on this information and need a
_CPC present. Prior to this change performance in Win10 never exceeds
80% and MSR 0x770 is 0, while with this change (and enabling eist) higher
speeds can be achieved and the MSR value is now 1.

This requirements are intended to support platform security

coreboot has to change its execution order to meet those

capability and PRM (processor reserved memory) of desired size (needs to
be configured through PrmrrSize) are provisioned for later software
stack to use SGX (i.e., run SGX enclaves).
One issue is still puzzling and needs to be addressed: by calling
configure_sgx() in cpu_core_init() which is the per-thread function, SGX
is always failing for thread 0 but is successful for other 3 threads.
I had to call configure_sgx() again from soc_init_cpus() which is the

Another pending work is the implementation for the Owner Epoch update
which shall be added later.

As per ME BWG, there are two mechanism to generate a Global
Reset (resets both host and Intel ME), one is through CF9h
IO write of 6h or Eh with "CF9h Global Reset" (CF9GR) bit set,
PMC PCI offset ACh[20]. Another is to issue the Global Reset
MEI message. Because any attempts to cause global reset without
synchronizing the two sides might cause unwanted side effects,
such as unwritten flash data that will get destroyed if the
host were to cause a global reset without informing Intel ME
firmware, the recommended method is to send a Global Reset MEI
message when the following conditions are met:
The PCH chipset firmware just needs to complete the Intel ME
Interface #1 initialization and check the Intel ME HFSTS state
if Intel ME is not in ERROR state and is accepting MEI commands
then firmware should be able to use Global Reset MEI message to
trigger global reset.
Furthermore, if Intel ME is in ERROR state, BIOS can use I/O 0xCF9
write of 0x06 or 0x0E command with PCH ETR3 register bit [20]
to perform the global reset.
BUG=none
