Which processors support the RDPID instruction?
How do I programmatically check if there is support for RDPID?
This is a standard feature bit supported by the CPUID instruction, as described in Volume 2 of the Intel Architectures SW Developer's Manual (document 325383).
Execute CPUID with eax=0x07 and ecx=0x00. After this, bit 22 of ecx is 1 if the RDPID instruction is supported.
Thanks for your reply. Any idea which processor family first introduced this instruction?
