Hi
I have captured the boot etl events using xperf command
Now i want to know the BIOS time.
For that iam using osloaderstart time as the time when BIOS finished
and gave control to OS.
Is it ok to assume this?
Also osloaderstart is given in terms of raw count which needs to be
resolved to time in sec.
For that is it fine to do below calculations:
osloaderstart_time_in_sec = osloaderstart_count/cpu_freq
Also just want to know whether OS make use of __rdtsc processor
counter for logging timer count in xperf logs?
thanks
