i915_perf_init(9)

💖 NAME 💖

i915_perf_init(9) from the Kernel API Manual — okay bestie, this one is i915_perf_init: initialize i915-perf state on module bind. that's the whole vibe ✨

🦋 SYNOPSIS 🦋

int i915_perf_init (struct drm_i915_private *i915 );

🎀 ARGUMENTS 🎀

• i915 — i915 device instance. that's the one and only arg, no cap 🫶

🌸 DESCRIPTION 🌸

Lowkey iconic setup moment: this initializes i915-perf state without exposing anything to userspace. It's giving behind-the-scenes main character energy — the state gets initialized, but userspace does not get a peek yet. 💅

📝 NOTE 📝

i915-perf initialization is split into an 'init' and 'register' phase with the i915_perf_register exposing state to userspace. ✨
