Wu Zhou c5d019b836 hv: emulate cpuids and MSRs for VHWP ... Changes made by this patch includes: 1. Emulate HWP and pstate MSRs/CPUIDs. Those are exposed to guest when the GUEST_FLAG_VHWP is set: - CPUID[6].EAX[7,9,10]: MSR_IA32_PM_ENABLE(enabled by hv, always read 1), MSR_IA32_HWP_CAPABILITIES, MSR_IA32_HWP_REQUEST, MSR_IA32_HWP_STATUS, - CPUID[6].ECX[0]: MSR_IA32_MPERF, MSR_IA32_APERF - MSR_IA32_PERF_STATUS(read as base frequency when not owning pCPU) - MSR_IA32_PERF_CTL(ignore writes) 2. Always hide HWP interrupt and package control MSRs/CPUIDs: - CPUID[6].EAX[8]: MSR_IA32_HWP_INTERRUPT(currently ACRN is not able to deliver thermal LVT virtual interrupt to guests) - CPUID[6].EAX[11,22]: MSR_IA32_HWP_REQUEST_PKG, MSR_IA32_HWP_CTL Tracked-On: #8414 Signed-off-by: Wu Zhou <wu.zhou@intel.com> Reviewed-by: Junjie Mao <junjie.mao@intel.com>		2023-06-09 10:06:42 +08:00
