Hi All,

 

Can I retrieve the time stamp count like RDTSC command?

There is a EfiReadTsc() function in the EDK, but I don’t know how to use it.

Also I can not add __asm{ rdtsc } call in my EFI driver (nmake efi64).

    ‘__asm’ keyword not supported on this architecture

 

Thanks,

 

 

Best regards,

Ming
