💅 kvm_arm_pmu_...max_counters(9) — bestie's guide to the Kernel API Manual ✨

okay so this is a page from the Kernel API Manual, and the function it's hyping up is genuinely so simple you're gonna be like "wait that's it?" — but it's a useful little guy, so let's give it the respect it deserves. 🫶

✨ NAME ✨

kvm_arm_pmu_get_max_counters — literally just returns the max number of PMU counters. that's the whole job. icon behaviour honestly. 👑

🌸 SYNOPSIS 🌸

u8 kvm_arm_pmu_get_max_counters (struct kvm *kvm );

so it hands you back a u8 (yes, a tiny unsigned byte, it's giving minimalism 💅) and it wants exactly one thing from you — a struct kvm * pointer. slay.

🎀 ARGUMENTS 🎀

  • kvm — the kvm pointer. that's it. that's the whole argument list. no cap, one (1) parameter, and it's just the kvm pointer, bestie. 🦋

🔥 SEE ALSO 🔥

the kernel file in question lives at ./arch/arm64/kvm/pmu-emul.c — that's where the whole PMU emulation situation happens, iykyk. and if you're the type to go down a rabbit hole (main character energy tbh), here's the whole friend group of related bits:

go read 'em, they're all part of the same little PMU family and they ate. 💖

real talk: this whole page is literally short and sweet, so there are no danger warnings, no undefined behaviour, no deprecated flags to tiptoe around. it's just a getter. breathe. 🌈

and that's the whole page, bestie — short, iconic, and to the point. this lil' doc came straight out of ./arch/arm64/kvm and it's stamped October 2026, so like… screenshot it for the group chat and go forth and query those counters. 🧚⭐💜
