#### 16.3.17 cpuid

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.
