| H A D | perf_event_attr_fprintf.c | 930e16ac Thu Mar 07 18:19:15 CST 2024 Ian Rogers <irogers@google.com> perf tools: Add/use PMU reverse lookup from config to name
[ Upstream commit 67ee8e71daabb8632931b7559e5c8a4b69a427f8 ]
Add perf_pmu__name_from_config that does a reverse lookup from a
config number to an alias name. The lookup is expensive as the config
is computed for every alias by filling in a perf_event_attr, but this
is only done when verbose output is enabled. The lookup also only
considers config, and not config1, config2 or config3.
An example of the output:
$ perf stat -vv -e data_read true
...
perf_event_attr:
type 24 (uncore_imc_free_running_0)
size 136
config 0x20ff (data_read)
sample_type IDENTIFIER

Committer notes:
Fix the python binding build by adding dummies for not strictly
needed perf_pmu__name_from_config() and perf_pmus__find_by_type().

930e16ac Thu Mar 07 18:19:15 CST 2024 Ian Rogers <irogers@google.com> perf tools: Add/use PMU reverse lookup from config to name
[ Upstream commit 67ee8e71daabb8632931b7559e5c8a4b69a427f8 ]
Add perf_pmu__name_from_config that does a reverse lookup from a
config number to an alias name. The lookup is expensive as the config
is computed for every alias by filling in a perf_event_attr, but this
is only done when verbose output is enabled. The lookup also only
considers config, and not config1, config2 or config3.
An example of the output:
$ perf stat -vv -e data_read true
...
perf_event_attr:
type 24 (uncore_imc_free_running_0)
size 136
config 0x20ff (data_read)
sample_type IDENTIFIER

Committer notes:
Fix the python binding build by adding dummies for not strictly
needed perf_pmu__name_from_config() and perf_pmus__find_by_type().

930e16ac Thu Mar 07 18:19:15 CST 2024 Ian Rogers <irogers@google.com> perf tools: Add/use PMU reverse lookup from config to name
[ Upstream commit 67ee8e71daabb8632931b7559e5c8a4b69a427f8 ]
Add perf_pmu__name_from_config that does a reverse lookup from a
config number to an alias name. The lookup is expensive as the config
is computed for every alias by filling in a perf_event_attr, but this
is only done when verbose output is enabled. The lookup also only
considers config, and not config1, config2 or config3.
An example of the output:
$ perf stat -vv -e data_read true
...
perf_event_attr:
type 24 (uncore_imc_free_running_0)
size 136
config 0x20ff (data_read)
sample_type IDENTIFIER
read_format TOTAL_TIME_ENABLED|TOTAL_TIME_RUNNING
disabled 1
inherit 1
exclude_guest 1
...
Committer notes:
Fix the python binding build by adding dummies for not strictly
needed perf_pmu__name_from_config() and perf_pmus__find_by_type().
