pmc.tsc

PMC.TSC(3)						   BSD Library Functions Manual 						PMC.TSC(3)

NAME

     pmc.tsc -- measurements using the i386 timestamp counter

LIBRARY

     Performance Counters Library (libpmc, -lpmc)

SYNOPSIS

     #include <pmc.h>

DESCRIPTION

     In the i386 architecture, the timestamp counter is a monotonically non-decreasing counter that counts processor cycles.

     This counter may be selected specifying an event specifier ``tsc'' to pmc_allocate(3).  The TSC is a read-only counter that may only be allo-
     cated in system-wide counting mode.  The ``tsc'' event does not support further event qualifiers.

     Multiple processes are allowed to allocate the TSC.  Once allocated, the TSC may be read using the pmc_read() function, or by using the RDTSC
     instruction.

   Event Name Aliases
     The alias ``cycles'' maps to the TSC.
