cpuid
Command
Command
cpuid [-l] [-p]
Check for CPU features. This command is only available on x86 systems.
With the -l
option, return true if the CPU supports long mode (64-bit).
With the -p
option, return true if the CPU supports Physical Address Extension (PAE).
If invoked without options, this command currently behaves as if it had been invoked with -l
. This may change in the future.
