NAME
     pmc.octeon - measurement events for Octeon family CPUs

LIBRARY
     Performance Counters Library (libpmc, -lpmc)

SYNOPSIS
     #include <pmc.h>

DESCRIPTION
     There are two counters per core supported by the hardware and each is 64
     bits wide.

   Event Specifiers (Programmable PMCs)
     MIPS programmable PMCs support the following events:

     CLK     (Event 1) Conditionally clocked cycles (as opposed to
             count/cvm_count which count even with no clocks)

     ISSUE   (Event 2) Instructions issued but not retired

     RET     (Event 3) Instructions retired

     NISSUE  (Event 4) Cycles no issue

     SISSUE  (Event 5) Cycles single issue

     DISSUE  (Event 6) Cycles dual issue

     IFI     (Event 7) Cycle ifetch issued (but not necessarily commit to
             pp_mem)

     BR      (Event 8) Branches retired

     BRMIS   (Event 9) Branch mispredicts

     J       (Event 10) Jumps retired

     JMIS    (Event 11) Jumps mispredicted

     REPLAY  (Event 12) Mem Replays

     IUNA    (Event 13) Cycles idle due to unaligned_replays

     TRAP    (Event 14) trap_6a signal

     UULOAD  (Event 16) Unexpected unaligned loads (REPUN=1)

     UUSTORE
             (Event 17) Unexpected unaligned store (REPUN=1)

     ULOAD   (Event 18) Unaligned loads (REPUN=1 or USEUN=1)

     USTORE  (Event 19) Unaligned store (REPUN=1 or USEUN=1)

     EC      (Event 20) Exec clocks(must set CvmCtl[DISCE] for accurate
             timing)

     MC      (Event 21) Mul clocks(must set CvmCtl[DISCE] for accurate timing)

     CC      (Event 22) Crypto clocks(must set CvmCtl[DISCE] for accurate
             timing)

     CSRC    (Event 23) Issue_csr clocks(must set CvmCtl[DISCE] for accurate
             timing)

     CFETCH  (Event 24) Icache committed fetches (demand+prefetch)

     CPREF   (Event 25) Icache committed prefetches

     ICA     (Event 26) Icache aliases

     II      (Event 27) Icache invalidates

     IP      (Event 28) Icache parity error

     CIMISS  (Event 29) Cycles idle due to imiss (must set CvmCtl[DISCE] for
             accurate timing)

     WBUF    (Event 32) Number of write buffer entries created

     WDAT    (Event 33) Number of write buffer data cycles used (may need to
             set CvmCtl[DISCE] for accurate counts)

     WBUFLD  (Event 34) Number of write buffer entries forced out by loads

     WBUFFL  (Event 35) Number of cycles that there was no available write
             buffer entry (may need to set CvmCtl[DISCE] and CvmMemCtl[MCLK]
             for accurate counts)

     WBUFTR  (Event 36) Number of stores that found no available write buffer
             entries

     BADD    (Event 37) Number of address bus cycles used (may need to set
             CvmCtl[DISCE] for accurate counts)

     BADDL2  (Event 38) Number of address bus cycles not reflected (i.e.
             destined for L2) (may need to set CvmCtl[DISCE] for accurate
             counts)

     BFILL   (Event 39) Number of fill bus cycles used (may need to set

     IDIDS   (Event 41) Number of Istream DIDs created

     DIDNA   (Event 42) Number of cycles that no DIDs were available (may need
             to set CvmCtl[DISCE] and CvmMemCtl[MCLK] for accurate counts)

     LDS     (Event 43) Number of load issues

     LMLDS   (Event 44) Number of local memory load

     IOLDS   (Event 45) Number of I/O load issues

     DMLDS   (Event 46) Number of loads that were not prefetches and missed in
             the cache

     STS     (Event 48) Number of store issues

     LMSTS   (Event 49) Number of local memory store issues

     IOSTS   (Event 50) Number of I/O store issues

     IOBDMA  (Event 51) Number of IOBDMAs
