NAME

       perf-mem - Profile memory accesses

SYNOPSIS

       perf mem [<options>] (record [<command>] | report)

DESCRIPTION

       "perf mem -t <TYPE> record" runs a command and gathers memory operation data from it, into perf.data. Perf record options are accepted and
       are passed through.

       "perf mem -t <TYPE> report" displays the result. It invokes perf report with the right set of options to display a memory access profile.

OPTIONS

       <command>...
	   Any command you can specify in a shell.

       -t, --type=
	   Select the memory operation type: load or store (default: load)

       -D, --dump-raw-samples=
	   Dump the raw decoded samples on the screen in a format that is easy to parse with one sample per line.

       -x, --field-separator
	   Specify the field separator used when dump raw samples (-D option). By default, The separator is the space character.

       -C, --cpu-list
	   Restrict dump of raw samples to those provided via this option. Note that the same option can be passed in record mode. It will be
	   interpreted the same way as perf record.

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
