perf_pmu__m...num_mem_pmus(9)

✨ NAME ✨

okay bestie so this is the Kernel API Manual entry for perf_pmu__mem_events_num_mem_pmus — and what it does is literally right there in the name: it gets you the number of mem PMUs since the given pmu 💅 (yes, "since" — that's the vibe, that's the wording, we're keeping it fr fr)

🫶 SYNOPSIS 🫶

int perf_pmu__mem_events_num_mem_pmus (struct perf_pmu *pmu );

like… the return type is int, the argument is a struct perf_pmu * called pmu, and that's the whole entire signature, no cap 💖

🌸 ARGUMENTS 🌸

• pmu — your start pmu 👑 this is where the counting begins. and here's the iconic part: if it's NULL, it searches the entire PMU list instead 🦋 so NULL = no starting point = the whole list gets the vibe check, iykyk ✨

💜 SEE ALSO 💜

• Kernel file ./tools/perf/util/mem-events.c — go read it, that's where the actual source lives 🎀

ngl bestie, this one is short and sweet — one arg, one return, one file. lowkey obsessed 😭💖

mwah 💋 that's a wrap — brought to you by the source over in <code>./tools/perf/util</code>, dated October 2026, and yes the header says perf_pmu__m...num_mem_pmus(9) because even manpage titles get truncated, we don't gatekeep 🙈
