ngl this page is short but she ate 💅 every detail's here, nothing dropped, we don't do that here 🙈

okay and before you go — cute little sign-off time 🎀 this whole thing comes from ./drivers/gpu/drm/i915, dated October 2026, and it's the i915_perf_ioctl_version(9) page, mwah 💋 go read some kernel source, ily, bye 🦋✨🌈
