💅 perf_pmu__ma...uffix_uncore(9) 💅

okay bestie, welcome to the Kernel API Manual ✨ this one's a little function with a very long name and a very specific job, and honestly? it ate. let's get into it 🫶

🌸 NAME 🌸

perf_pmu__match_ignoring_suffix_uncore — so like, the whole question this function is asking is: does the pmu_name match tok if we just… ignore any trailing suffix on pmu_name and on tok? 🙈 lowkey genius. and to be clear, that suffix has to be in the form tok_{digits}, or tok{digits}. no other silliness allowed, ok? 💅

---

✨ SYNOPSIS ✨

bool perf_pmu__match_ignoring_suffix_uncore (const char *pmu_name ,
       const char *tok );

it returns a bool, it takes two const char *, and yes that's the whole vibe check 💖

🎀 ARGUMENTS 🎀

• pmu_name — the pmu_name in question, and it might have a suffix on the end. might not. we don't judge, we just check 👑
• tok — the possible match for pmu_name. like, the candidate. the one being compared against. the moment of truth fr fr ⭐
