💅 i915_driver_mmio_probe(9) — the Kernel API Manual glow-up ✨

okay so bestie, welcome to the Kernel API Manual page for i915_driver_mmio_probe, and honestly? this one's a little baddie with a very specific job. let's get into it 🎀

🌸 NAME 🌸

i915_driver_mmio_probe — setup device MMIO. that's it, that's the whole vibe. MMIO setup era 💅

✨ SYNOPSIS ✨

int i915_driver_mmio_probe (struct drm_i915_private *dev_priv );

like yes, that's the signature, copy it exactly, don't be cute with it 🫶

🦋 ARGUMENTS 🦋

  • dev_priv — device private. that's the parameter, that's what it is, it's the device private struct and it's literally the main character here 👑

💖 DESCRIPTION 💖

okay so here's the tea ☕ — this function sets up the minimal device state that you need so that MMIO accesses actually work later on in the initialization sequence. it's the groundwork, the pre-game, the getting ready montage of driver init 🌈

and the way that it stays in its lane? iconic. the setup here should avoid any other device-wide side effects — no cap, none — and it should also avoid exposing the driver via kernel internal interfaces or user space interfaces. like, do your little MMIO thing and don't make it everyone's business 🙈

ngl the restraint is the whole point: minimal state, no extra side effects, no surfacing the driver anywhere yet. periodt ✨

🎀 SEE ALSO 🎀

the friend group ofc 💜 — and yes, the kernel file is right here:

and that's the page!! 🦋 sign-off time: this lil beauty lives under ./drivers/gpu/drm/i915 and it's dated October 2026 — so go forth, set up that MMIO, and slay 💅💖✨
