[igt-dev] [PATCH i-g-t] scripts/trace.pl: Remove the tool
Tvrtko Ursulin
tvrtko.ursulin at linux.intel.com
Mon Mar 22 14:11:50 UTC 2021
From: Tvrtko Ursulin <tvrtko.ursulin at intel.com>
Tool has been broken for a while after changes to tracepoint format an
behaviour. Although I have patches somewhere to mostly fix it, it seems
that it has outlived its usefulness and could be deleted just as well.

-Notes:
-
- The tool parse the output generated by the 'perf script' command after the
- correct set of i915 tracepoints have been collected via perf record.
-
- To collect the data:
-
- ./trace.pl --trace [command-to-be-profiled]
-
- The above will invoke perf record, or alternatively it can be done directly:
-
- perf record -a -c 1 -e i915:intel_gpu_freq_change, \
- i915:i915_request_add, \
- i915:i915_request_submit, \
- i915:i915_request_in, \
- i915:i915_request_out, \
- dma_fence:dma_fence_signaled, \
- i915:i915_request_wait_begin, \
- i915:i915_request_wait_end \
- [command-to-be-profiled]
-
- Then create the log file with:
-
- perf script >trace.log
-
- This file in turn should be piped into this tool which will generate some
- statistics out of it, or if --html was given HTML output.
-
- HTML can be viewed from a directory containing the 'vis' JavaScript module.
- On Ubuntu this can be installed like this:
-
- apt-get install npm
- npm install vis
-
-Usage:
- trace.pl <options> <input-file >output-file
-
- --help / -h This help text
- --max-items=num / -m num Maximum number of boxes to put on the
- timeline. More boxes means more work for
- the JavaScript engine in the browser.
- --zoom-width-ms=ms / -z ms Width of the initial timeline zoom
- --split-requests / -s Try to split out request which were
- submitted together due coalescing in the
- driver. May not be 100% accurate and may
- influence the per-engine statistics so
- use with care.
- --ignore-ring=id / -i id Ignore ring with the numerical id when
- parsing the log (enum intel_engine_id).
- Can be given multiple times.
- --skip-box=name / -x name Do not put a certain type of a box on
- the timeline. One of: queue, ready,
- execute and ctxsave.
- Can be given multiple times.
- --html Generate HTML output.
- --trace cmd Trace the following command.
- --avg-delay-stats Print average delay stats.
- --gpu-timeline Draw overall GPU busy timeline.
- --colour-contexts / -c Use different colours for different
- context execution boxes.
