perf script python: Fix export-to-postgresql.py occasional failure

2018-10-20T07:52:34+00:00

commit 25e11700b54c7b6b5ebfc4361981dae12299557b upstream.

Occasional export failures were found to be caused by truncating 64-bit
pointers to 32-bits. Fix by explicitly setting types for all ctype
arguments and results.

cs-etm: associating output packet with CPU they executed on

2016-06-20T17:16:09+00:00

This patch adds the required mechanic to quickly lookup the CPU number
associated with a traceID.  That way the CPU that executed the code
conveyed by a decoded packet can be identified, without having to
do unecessary translations.

Using this new functionality the "cs-trace-disasm.py" script is
enhanced to output the file and CPU number the code has been
executed on:

perf scripts python: Add new compaction-times script

2015-08-28T17:53:40+00:00

This patch creates a new script (compaction-times) to report time
spent in mm compaction. It is possible to report times in nanoseconds
(default) or microseconds (-u).

The option -p will break down results by process id, -pv will further
decompose by each compaction entry/exit.

For each compaction entry/exit what is reported is controlled by the
options:

  -t   report only timing
  -m   report migration stats
  -ms  report migration scanner stats
  -fs  report free scanner stats

The default is to report all.

Entries may be further filtered by pid, pid-range or comm (regex).

The script is useful when analysing workloads that compact memory. The
most common example will be THP allocations on systems with a lot of
uptime that has fragmented memory.

This is an example of using the script to analyse a thpscale from
mmtests which deliberately fragments memory and allocates THP in 4
separate threads

  # Recording step, one of the following;
  $ perf record -e 'compaction:mm_compaction_*' ./workload

perf tools: Add example call-graph script

2015-08-21T15:32:40+00:00

Add a script to produce a call-graph from data exported to a postgresql
database and derived from a processor trace event like intel_pt or intel_bts.

Refer to comments in the scripts call-graph-from-postgresql.py and
export-to-postgresql.py for more details on how to set up the environment,
install the required packages, etc.

Committer note:

From the scripts, for convenience while reading 'git log':

  An example of using this script with Intel PT:
