-.Sh LIBRARY
-.Lb libpmc
-.Sh SYNOPSIS
-.In pmc.h
-.Sh DESCRIPTION
-.Tn Intel XScale
-CPUs are ARM CPUs based on the ARMv5e core.
-.Pp
-Second generation cores have 2 counters, while third generation cores
-have 4 counters.
-Third generation cores also have an increased number of PMC events.
-.Pp
-.Tn Intel XScale
-PMCs are documented in
-.Rs
-.%B "3rd Generation Intel XScale Microarchitecture Developer's Manual"
-.%D May 2007
-.Re
-.Ss Event Specifiers (Programmable PMCs)
-.Tn Intel XScale
-programmable PMCs support the following events:
-.Bl -tag -width indent
-.It Li IC_FETCH
-External memory fetch due to L1 instruction cache miss.
-.It Li IC_MISS
-Instruction cache or TLB miss.
-.It Li DATA_DEPENDENCY_STALLED
-A data dependency stalled
-.It Li ITLB_MISS
-Instruction TLB miss.
-.It Li DTLB_MISS
-Data TLB miss.
-.It Li BRANCH_RETIRED
-Branch instruction retired (executed).
-.It Li BRANCH_MISPRED
-Branch mispredicted.
-.It Li INSTR_RETIRED
-Instructions retired (executed).
-.It Li DC_FULL_CYCLE
-L1 data cache buffer full stall.
-Event occurs on every cycle the
-condition is present.
-.It Li DC_FULL_CONTIG
-L1 data cache buffer full stall.
-Event occurs once for each contiguous sequence of this type of stall.
-.It Li DC_ACCESS
-L1 data cache access, not including cache operations.
-.It Li DC_MISS
-L1 data cache miss, not including cache operations.
-.It Li DC_WRITEBACK
-L1 data cache write-back.
-Occurs for each cache line that's written back from the cache.
-.It Li PC_CHANGE
-Software changed the program counter.
-.It Li BRANCH_RETIRED_ALL
-Branch instruction retired (executed).
-This event counts all branch instructions, indirect or direct.
-.It Li INSTR_CYCLE
-Count the number of microarchitecture cycles each instruction requires
-to issue.
-.It Li CP_STALL
-Coprocessor stalled the instruction pipeline.
-.It Li PC_CHANGE_ALL
-Software changed the program counter (includes exceptions).
-.It Li PIPELINE_FLUSH
-Pipeline flushes due to mispredictions or exceptions.
-.It Li BACKEND_STALL
-Backend stalled the instruction pipeline.
-.It Li MULTIPLIER_USE
-Multiplier used.
-.It Li MULTIPLIER_STALLED
-Multiplier stalled the instruction pipeline.
-.It Li DATA_CACHE_STALLED
-Data cache stalled the instruction pipeline.
-.It Li L2_CACHE_REQ
-L2 cache request, not including cache operations.
-.It Li L2_CACHE_MISS
-L2 cache miss, not including cache operations.
-.It Li ADDRESS_BUS_TRANS
-Address bus transaction.
-.It Li SELF_ADDRESS_BUS_TRANS
-Self initiated address bus transaction.
-.It Li DATA_BUS_TRANS
-Data bus transaction.

-.Ss Event Name Aliases
-The following table shows the mapping between the PMC-independent
-aliases supported by
-.Lb libpmc
-and the underlying hardware events used.
