cpu(9v)
NAME
  cpu - Global Variable: Provides a unique logical processor-type family
  identifier

SYNOPSIS
  extern int cpu;

DESCRIPTION
  The cpu global variable provides a unique logical family identifier of the
  processor type of the running system. The logical system name can represent
  a single processor or a family of processor types.  For example, the
  constant DEC_3000_500 represents the	DEC 3000 Model 500 Alpha Workstation.
  The defined processor names appear in the following file:
  /usr/sys/include/arch/alpha/hal/cpuconf.h.

  You use the cpu global variable to conditionally execute processor-specific
  code. For example, the following code fragment calls a system-specific
  initialization interface for the DEC 3000 Model 500 Alpha Workstation:

	.
	.
	.
       if (cpu == DEC_3000_500) {
	       init_3000_500();
       }
	.
	.
	.
