NAME

       perf-annotate - Read perf.data (created by perf record) and display annotated code

SYNOPSIS

       perf annotate [-i <file> | --input=file] [symbol_name]

DESCRIPTION

       This command reads the input file and displays an annotated version of the code. If the object file has debug symbols then the source code
       will be displayed alongside assembly code.

       If there is no debug info in the object, then annotated assembly is displayed.

OPTIONS

       -i, --input=
	   Input file name. (default: perf.data unless stdin is a fifo)

       -d, --dsos=<dso[,dso...]>
	   Only consider symbols in these dsos.

       -s, --symbol=<symbol>
	   Symbol to annotate.

       -f, --force
	   Don't complain, do it.

       -v, --verbose
	   Be more verbose. (Show symbol address, etc)

       -D, --dump-raw-trace
	   Dump raw trace in ASCII.

       -k, --vmlinux=<file>
	   vmlinux pathname.

       -m, --modules
	   Load module symbols. WARNING: use only with -k and LIVE kernel.

       -l, --print-line
	   Print matching source lines (may be slow).

       -P, --full-paths
	   Don't shorten the displayed pathnames.

       --stdio
	   Use the stdio interface.

       --tui
	   Use the TUI interface. Use of --tui requires a tty, if one is not present, as when piping to other commands, the stdio interface is
	   used. This interfaces starts by centering on the line with more samples, TAB/UNTAB cycles through the lines with more samples.

       --gtk
	   Use the GTK interface.

       -C, --cpu
	   Only report samples for the list of CPUs provided. Multiple CPUs can be provided as a comma-separated list with no space: 0,1. Ranges
	   of CPUs are specified with -: 0-2. Default is to report samples on all CPUs.

       --asm-raw
	   Show raw instruction encoding of assembly instructions.

       --source
	   Interleave source code with assembly code. Enabled by default, disable with --no-source.

       --symfs=<directory>
	   Look for files with symbols relative to this directory.

       -M, --disassembler-style=
	   Set disassembler style for objdump.

       --objdump=<path>
	   Path to objdump binary.

       --skip-missing
	   Skip symbols that cannot be annotated.

       --group
	   Show event group information together

NAME

       tapset::perf - systemtap perf probe points

DESCRIPTION

       This  family  of probe points is used to probe "perf events" on suitably configured kernels (2.6.33+).  It contains a number of aliases for
       the ABI-specified event type/config tuples.

       The default sampling interval of the translator(1000000) is not overridden, so some of these probe points may fire very infrequently.  Use
       the lower level perf.type(AA).config(BB).sample(CC) probe point if this is a problem.

       perf.hw.*
	      A  variety of hardware events, as generalized by the kernel.  These generally require running on bare hardware with selected proces-
	      sors.
	      probe perf.hw.cpu_cycles
	      probe perf.hw.instructions
	      probe perf.hw.cache_references
	      probe perf.hw.cache_misses
	      probe perf.hw.branch_instructions
	      probe perf.hw.branch_misses
	      probe perf.hw.bus_cycles

       perf.sw.*
	      Special "software" events provided by the kernel.  These sometimes work in virtualized environments and with more  processor  archi-
	      tectures.
	      probe perf.sw.cpu_clock
	      probe perf.sw.task_clock
	      probe perf.sw.page_faults
	      probe perf.sw.context_switches
	      probe perf.sw.cpu_migrations
	      probe perf.sw.page_faults_min
	      probe perf.sw.page_faults_maj
	      probe perf.sw.alignment_faults
	      probe perf.sw.emulation_faults

       perf.hw_cache.TYPE.ACCESS.RESULT
	      Hardware cache events, where available.  A subset of the following cartesian product may be available:
	      probe perf.hw_cache.l1d.*.*
	      probe perf.hw_cache.l1i.*.*
	      probe perf.hw_cache.ll.*.*
	      probe perf.hw_cache.dtlb.*.*
	      probe perf.hw_cache.itlb.*.*
	      probe perf.hw_cache.bpu.*.*

	      probe perf.hw_cache.*.read.*
	      probe perf.hw_cache.*.write.*
	      probe perf.hw_cache.*.prefetch.*

	      probe perf.hw_cache.*.*.access
	      probe perf.hw_cache.*.*.miss
