perf list: Remove unused 'sep' variable

2025-12-17T12:30:37+00:00

It is just being set to the return of strchr() but never used, just ditch it and with it get rid of a warning about it not being const on fedora 44. Reviewed-by: Ian Rogers Link: https://lore.kernel.org/r/20251211221756.96294-2-acme@kernel.org Signed-off-by: Arnaldo Carvalho de Melo

perf list: Support filtering in JSON output

2025-11-20T19:11:48+00:00

Like regular output mode, it should honor command line arguments to limit to a certain type of PMUs or events. $ perf list -j hw [ { "Unit": "cpu", "Topic": "legacy hardware", "EventName": "branch-instructions", "EventType": "Kernel PMU event", "BriefDescription": "Retired branch instructions [This event is an alias of branches]", "Encoding": "cpu/event=0xc4\n/" }, { "Unit": "cpu", "Topic": "legacy hardware", "EventName": "branch-misses", "EventType": "Kernel PMU event", "BriefDescription": "Mispredicted branch instructions", "Encoding": "cpu/event=0xc5\n/" }, ...

perf list: Share print state with JSON output

2025-11-20T19:11:48+00:00

The JSON print state has only one different field (need_sep). Let's add the default print state to the json state and use it. Then we can use the 'ps' variable to update the state properly. This is a preparation for the next commit. Reviewed-by: Ian Rogers Signed-off-by: Namhyung Kim

perf list: Print matching PMU events for --unit

2025-11-20T19:11:48+00:00

When --unit option is used, pmu_glob is set to the argument. It should match with event PMU and display the matching ones only. But it also shows raw events and metrics after that. $ perf list --unit tool List of pre-defined events (to be used in -e or -M): tool: core_wide [1 if not SMT,if SMT are events being gathered on all SMT threads 1 otherwise 0. Unit: tool] duration_time [Wall clock interval time in nanoseconds. Unit: tool] has_pmem [1 if persistent memory installed otherwise 0. Unit: tool] num_cores [Number of cores. A core consists of 1 or more thread,with each thread being associated with a logical Linux CPU. Unit: tool] num_cpus [Number of logical Linux CPUs. There may be multiple such CPUs on a core. Unit: tool] ... rNNN [Raw event descriptor] cpu/event=0..255,pc,edge,.../modifier [Raw event descriptor] [(see 'man perf-list' or 'man perf-record' on how to encode it)] breakpoint//modifier [Raw event descriptor] cstate_core/event=0..0xffffffffffffffff/modifier [Raw event descriptor] cstate_pkg/event=0..0xffffffffffffffff/modifier [Raw event descriptor] drm_i915//modifier [Raw event descriptor] hwmon_acpitz//modifier [Raw event descriptor] hwmon_ac//modifier [Raw event descriptor] hwmon_bat0//modifier [Raw event descriptor] hwmon_coretemp//modifier [Raw event descriptor] ...

perf print-events: Remove print_symbol_events

2025-10-15T14:59:11+00:00

Now legacy hardware events are in json there's no need for a specific printing routine that previously served for both hardware and software events. The associated event_symbols_hw is also removed. To support the previous filtered version use an event glob of "legacy hardware" which matches the topic of the json events.

perf list: Remove tracepoint printing code

Now that the tp_pmu can iterate and describe events remove the custom tracepoint printing logic, this avoids perf list showing the tracepoint events twice.
