REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2040 Below code is current implementation: if (MsrRegister[ProcessorNumber].Bits.Lock == 0) { CPU_REGISTER_TABLE_WRITE_FIELD ( ProcessorNumber, Msr, MSR_IA32_FEATURE_CONTROL, MSR_IA32_FEATURE_CONTROL_REGISTER, Bits.Lock, 1 ); } 1. In first normal boot, the Bits.Lock is 0, 1 will be added into the register table and then will set to the MSR. 2. Trig warm reboot, MSR value preserves. After normal boot phase, the Bits.Lock is 1, so it will not be added into the register table during the warm reboot phase. 3. Trig S3 then resume, the Bits.Lock change to 0 and Bits.Lock is not added in register table, so it's still 0 after resume. This is not an expect behavior. The expect value is the value should always 1 after booting or resuming from S3. The root cause for this issue is 1. driver bases on current value to insert the "set value action" to the register table. 2. Some MSRs may reserve their value during warm reboot. The solution for this issue is using new added macros for the MSRs which preserve value during warm reboot.
