-.Dt PMC.MIPS24K 3
-.Os
-.Sh NAME
-.Nm pmc.mips24k
-.Nd measurement events for
-.Tn MIPS24K
-family CPUs
-.Sh LIBRARY
-.Lb libpmc
-.Sh SYNOPSIS
-.In pmc.h
-.Sh DESCRIPTION
-MIPS PMCs are present in MIPS
-.Tn "24k"
-and other processors in the MIPS family.
-.Pp
-There are two counters supported by the hardware and each is 32 bits
-wide.
-.Pp
-MIPS PMCs are documented in
-.Rs
-.%B "MIPS32 24K Processor Core Family Software User's Manual"
-.%D December 2008
-.%Q "MIPS Technologies Inc."
-.Re
-.Ss Event Specifiers (Programmable PMCs)
-MIPS programmable PMCs support the following events:
-.Bl -tag -width indent
-.It Li CYCLE
-.Pq Event 0, Counter 0/1
-Total number of cycles.
-The performance counters are clocked by the
-top-level gated clock.
-If the core is built with that clock gater
-present, none of the counters will increment while the clock is
-stopped - due to a WAIT instruction.
-.It Li INSTR_EXECUTED
-.Pq Event 1, Counter 0/1
-Total number of instructions completed.
-.It Li BRANCH_COMPLETED
-.Pq Event 2, Counter 0
-Total number of branch instructions completed.
-.It Li BRANCH_MISPRED
-.Pq Event 2, Counter 1
-Counts all branch instructions which completed, but were mispredicted.
-.It Li RETURN
-.Pq Event 3, Counter 0
-Counts all JR R31 instructions completed.
-.It Li RETURN_MISPRED
-.Pq Event 3, Counter 1
-Counts all JR $31 instructions which completed, used the RPS for a prediction, but were mispredicted.
-.It Li RETURN_NOT_31
-.Pq Event 4, Counter 0
-Counts all JR $xx (not $31) and JALR instructions (indirect jumps).
-.It Li RETURN_NOTPRED
-.Pq Event 4, Counter 1
-If RPS use is disabled, JR $31 will not be predicted.
-.It Li ITLB_ACCESS
-.Pq Event 5, Counter 0
-Counts ITLB accesses that are due to fetches showing up in the
-instruction fetch stage of the pipeline and which do not use a fixed
-mapping or are not in unmapped space.
-If an address is fetched twice from the pipe (as in the case of a
-cache miss), that instruction willcount as 2 ITLB accesses.
-Since each fetch gets us 2 instructions,there is one access marked per double
-word.
-.It Li ITLB_MISS
-.Pq Event 5, Counter 1
-Counts all misses in the ITLB except ones that are on the back of another
-miss.
-We cannot process back to back misses and thus those are
-ignored.
-They are also ignored if there is some form of address error.
-.It Li DTLB_ACCESS
-.Pq Event 6, Counter 0
-Counts DTLB access including those in unmapped address spaces.
-.It Li DTLB_MISS
-.Pq Event 6, Counter 1
-Counts DTLB misses.
-Back to back misses that result in only one DTLB
-entry getting refilled are counted as a single miss.
-.It Li JTLB_IACCESS
-.Pq Event 7, Counter 0
-Instruction JTLB accesses are counted exactly the same as ITLB misses.
-.It Li JTLB_IMISS
-.Pq Event 7, Counter 1
-Counts instruction JTLB accesses that result in no match or a match on
-an invalid translation.
-.It Li JTLB_DACCESS
-.Pq Event 8, Counter 0
-Data JTLB accesses.
-.It Li JTLB_DMISS
-.Pq Event 8, Counter 1
-Counts data JTLB accesses that result in no match or a match on an invalid translation.
-.It Li IC_FETCH
-.Pq Event 9, Counter 0
-Counts every time the instruction cache is accessed.
-All replays,
-wasted fetches etc. are counted.
-For example, following a branch, even though the prediction is taken,
-the fall through access is counted.
-.It Li IC_MISS
-.Pq Event 9, Counter 1
-Counts all instruction cache misses that result in a bus request.
-.It Li DC_LOADSTORE
-.Pq Event 10, Counter 0
-Counts cached loads and stores.
-.It Li DC_WRITEBACK
-.Pq Event 10, Counter 1
-Counts cache lines written back to memory due to replacement or cacheops.
-.It Li DC_MISS
-.Pq Event 11, Counter 0/1
-Counts loads and stores that miss in the cache
-.It Li LOAD_MISS
-.Pq Event 13, Counter 0
-Counts number of cacheable loads that miss in the cache.
-.It Li STORE_MISS
-.Pq Event 13, Counter 1
-Counts number of cacheable stores that miss in the cache.
-.It Li INTEGER_COMPLETED
-.Pq Event 14, Counter 0
-Non-floating point, non-Coprocessor 2 instructions.
-.It Li FP_COMPLETED
-.Pq Event 14, Counter 1
-Floating point instructions completed.
-.It Li LOAD_COMPLETED
-.Pq Event 15, Counter 0
-Integer and co-processor loads completed.
-.It Li STORE_COMPLETED
-.Pq Event 15, Counter 1
-Integer and co-processor stores completed.
-.It Li BARRIER_COMPLETED
-.Pq Event 16, Counter 0
-Direct jump (and link) instructions completed.
-.It Li MIPS16_COMPLETED
-.Pq Event 16, Counter 1
-MIPS16c instructions completed.
-.It Li NOP_COMPLETED
-.Pq Event 17, Counter 0
-NOPs completed.
-This includes all instructions that normally write to a general
-purpose register, but where the destination register was set to r0.
-.It Li INTEGER_MULDIV_COMPLETED
-.Pq Event 17, Counter 1
-Integer multiply and divide instructions completed. (MULxx, DIVx, MADDx, MSUBx).
-.It Li RF_STALL
-.Pq Event 18, Counter 0
-Counts the total number of cycles where no instructions are issued
-from the IFU to ALU (the RF stage does not advance) which includes
-both of the previous two events.
-The RT_STALL is different than the sum of them though because cycles
-when both stalls are active will only be counted once.
-.It Li INSTR_REFETCH
-.Pq Event 18, Counter 1
-replay traps (other than uTLB)
-.It Li STORE_COND_COMPLETED
-.Pq Event 19, Counter 0
-Conditional stores completed.
-Counts all events, including failed stores.
-.It Li STORE_COND_FAILED
-.Pq Event 19, Counter 1
-Conditional store instruction that did not update memory.
-Note: While this event and the SC instruction count event can be configured to
-count in specific operating modes, the timing of the events is much
-different and the observed operating mode could change between them,
-causing some inaccuracy in the measured ratio.
-.It Li ICACHE_REQUESTS
-.Pq Event 20, Counter 0
-Note that this only counts PREFs that are actually attempted.
-PREFs to uncached addresses or ones with translation errors are not counted
-.It Li ICACHE_HIT
-.Pq Event 20, Counter 1
-Counts PREF instructions that hit in the cache
-.It Li L2_WRITEBACK
-.Pq Event 21, Counter 0
-Counts cache lines written back to memory due to replacement or cacheops.
-.It Li L2_ACCESS
-.Pq Event 21, Counter 1
-Number of accesses to L2 Cache.
-.It Li L2_MISS
-.Pq Event 22, Counter 0
-Number of accesses that missed in the L2 cache.
-.It Li L2_ERR_CORRECTED
-.Pq Event 22, Counter 1
-Single bit errors in L2 Cache that were detected and corrected.
-.It Li EXCEPTIONS
-.Pq Event 23, Counter 0
-Any type of exception taken.
-.It Li RF_CYCLES_STALLED
-.Pq Event 24, Counter 0
-Counts cycles where the LSU is in fixup and cannot accept a new
-instruction from the ALU.
-Fixups are replays within the LSU that occur when an instruction needs
-to re-access the cache or the DTLB.
-.It Li IFU_CYCLES_STALLED
-.Pq Event 25, Counter 0
-Counts the number of cycles where the fetch unit is not providing a
-valid instruction to the ALU.

-.Pq Event 25, Counter 1
-Counts the number of cycles where the ALU pipeline cannot advance.
-.It Li UNCACHED_LOAD
-.Pq Event 33, Counter 0
-Counts uncached and uncached accelerated loads.
-.It Li UNCACHED_STORE
-.Pq Event 33, Counter 1
-Counts uncached and uncached accelerated stores.

-Co-processor 2 register to register instructions completed.
-.It Li MFTC_COMPLETED
-.Pq Event 35, Counter 1
-Co-processor 2 move to and from instructions as well as loads and stores.
-.It Li IC_BLOCKED_CYCLES
-.Pq Event 37, Counter 0

-Ignores the stalls due to ITLB misses as well as the 4 cycles
-following a redirect.
-.It Li DC_BLOCKED_CYCLES
-.Pq Event 37, Counter 1
-Counts all cycles where integer pipeline waits on Load return data due
-to a D-cache miss.
-The LSU can signal a "long stall" on a D-cache misses, in which case
-the waiting TC might be rescheduled so other TCs can execute
-instructions till the data returns.
-.It Li L2_IMISS_STALL_CYCLES
-.Pq Event 38, Counter 0
-Cycles where the main pipeline is stalled waiting for a SYNC to complete.
-.It Li L2_DMISS_STALL_CYCLES
-.Pq Event 38, Counter 1
-Cycles where the main pipeline is stalled because of an index conflict
-in the Fill Store Buffer.
-.It Li DMISS_CYCLES
-.Pq Event 39, Counter 0
-Data miss is outstanding, but not necessarily stalling the pipeline.
-The difference between this and D$ miss stall cycles can show the gain
-from non-blocking cache misses.
-.It Li L2_MISS_CYCLES
-.Pq Event 39, Counter 1
-L2 miss is outstanding, but not necessarily stalling the pipeline.
-.It Li UNCACHED_BLOCK_CYCLES
-.Pq Event 40, Counter 0

-.It Li ISPRAM_STALL_CYCLES
-.Pq Event 43, Counter 0
-Count all pipeline bubbles that are a result of multicycle ISPRAM
-access.
-Pipeline bubbles are defined as all cycles that IFU doesn't present an
-instruction to ALU.
-The four cycles after a redirect are not counted.
-.It Li DSPRAM_STALL_CYCLES
-.Pq Event 43, Counter 1
-Counts stall cycles created by an instruction waiting for access to DSPRAM.
-.It Li CACHE_STALL_CYCLES
-.Pq Event 44, Counter 0
