Hi Chris, Arnaldo, Jiri,
We observe the parsing error for "software/xxx/" on some platforms.
For example,
# perf stat -e software/r1a/ -a -- sleep 1
event syntax error: 'software/r1a/'
\___ parser error
Run 'perf list' for a list of valid events
Usage: perf stat [<options>] [<command>]
-e, --event <event> event selector. use 'perf list' to list available
events
And perf test is failed too.
# perf test 6 -vv
...
running test 4 'software/r1a/'failed to parse event 'software/r1a/', err 1, str
'parser error'
event syntax error: 'software/r1a/'
\___ parser error
running test 4 'software/r0x1a/'failed to parse event 'software/r0x1a/', err 1,
str 'parser error'
event syntax error: 'software/r0x1a/'
\___ parser error
...
The issue should be the conflict between event "i915/software-gt-awake-time/" and pmu
"software".
# perf list | grep i915/software
i915/software-gt-awake-time/ [Kernel PMU event]
Perf supports the event format as "prefix-xxx-suffix", so the "software" string in
"software-gt-awake-time" is added to perf_pmu_events_list as PMU_EVENT_SYMBOL_PREFIX. When parsing
the string such as "software/xxx/", it’s parsed as PMU_EVENT_SYMBOL_PREFIX for "software", then it
would error out in next processing.
So the easy way is to rename "software-gt-awake-time" to "gt-awake-time", right? Otherwise we have
to hardcode something in perf tool.
What do you think of this issue and the solution?
BTW, as the robot reported, it's related to the commit 8c3b1ba0e7ea ("drm/i915/gt: Track the overall
awake/busy time").
Thanks
