okay bestie, welcome to the Linux Programmer's Manual 🎀 this one's short and sweet, ngl, but it's important. Sit down, grab a boba, let's talk about the ARM Cortex A8 PMU support in libpfm. 🦋

✨ NAME ✨

libpfm_arm_ac8 — support for ARM Cortex A8 PMU 🧚

yes that's the whole name section, she's lowkey a one-line icon, periodt.

🌸 SYNOPSIS 🌸

#include <perfmon/pfmlib.h>

And then the two little identity cards you gotta know about:

• PMU name: arm_ac8
• PMU desc: ARM Cortex A8

that's it, that's the whole incantation, no extra flags, no secret handshake. 💅

💫 DESCRIPTION 💫

So basically: the library supports the ARM Cortex A8 core PMU. slay. 🌈

Here's the tea tho, and it's genuinely useful tea:

• This PMU supports 2 counters — just two, bestie. Two. That's your whole budget. Spend them wisely. ✌️
• It has no privilege levels filtering. Nope, none, not a thing here. 🙈
• No event modifiers are available. Zero. Not one. Don't go looking for them, they are not in the building. 💀

fr fr, this is the "simple and honest" era of PMU support and we respect her for it. 👑
