gpu_metrics(9)

💖 gpu_metrics 💖

okay so bestie, welcome to the gpu_metrics page — it lives in the Kernel API Manual, and it's basically the group chat of your GPU's vitals. 🩺✨

🌸 NAME 🌸

gpu_metrics — the sysfs hookup the amdgpu driver gives you for pulling current gpu metrics data. no cap. 💅

✨ DESCRIPTION ✨

so here's the vibe: the amdgpu driver ships a sysfs API for grabbing the current gpu metrics data, and the file gpu_metrics is the one that does it. 🎀

literally just read the file and it dumps all the current gpu metrics data at you. that's the whole trick, iykyk. 🦋

and what's actually in that dump? bestie, hold on:

• 🌡️ temperature
• ⚡ frequency
• 🔥 engines utilization
• 🔌 power consume
• 💀 throttler status
• 🌀 fan speed
• 🧠 cpu core statistics — available for APU only, so don't come for me if they're missing, it's not me it's your hardware 🙈

the way that it gives you a snapshot of all sensors at the same time — iconic. one read, everything at once, periodt. 👑
