Hello everyone, noob here.
I need an accurate timestamp counter for a UEFI_APPLICATION.
currently i'm ussing
MdePkg/Library/SecPeiDxeTimerLibCpu/SecPeiDxeTimerLibCpu.inf for the TimerLib but
GetPerformanceCounter always returns 0.
I read a bit about APIC and it seems that it needs to be initialized to work?
What do I need to do to get GetPerformanceCounter to work?
