💅 amdgpu_fence_driver_start_ring — a Kernel API Manual moment

okay bestie, welcome to the Kernel API Manual ✨ no cap, this is the page for amdgpu_fence_driver_start_ring, and it's literally the glow-up moment where the fence driver gets told to get ready. sit down, hydrate, let's go 🫶

🌸 NAME 🌸

amdgpu_fence_driver_start_ring — make the fence driver ready for use on the requested ring. that's it, that's the whole vibe 💫

✨ SYNOPSIS ✨

int amdgpu_fence_driver_start_ring (struct amdgpu_ring *ring , struct
amdgpu_irq_src *irq_src , unsigned int irq_type );

like, the signature is right there, bestie — copy it exactly, don't @ me 🎀

🦋 ARGUMENTS 🦋

  • ring — ring to start the fence driver on 💍 like yes, this is the ring we're doing the whole thing for
  • irq_src — interrupt source to use for this ring, the little messenger it listens to 👀
  • irq_type — interrupt type to use for this ring, the flavor of that interrupt 🍓

🔥 DESCRIPTION 🔥

Make the fence driver ready for processing (all asics). periodt. that's the entire assignment 💅

the way that this works is — not all asics have all rings, so each asic will only start the fence driver on the rings it has. so it's giving "know your limits, respect your limits," and honestly? iconic. no asic is out here starting ring drivers for rings it doesn't even have, that would be so embarrassing for everyone 😭

Returns 0 for success, errors for failure. so if you get 0, slay, you ate. any other number? that's a failure, bestie, and you should probably look into that 🙈

👑 SEE ALSO 👑

Kernel file ./drivers/gpu/drm/amd/amdgpu/amdgpu_fence.c — that's where the whole fence family lives, iykyk 📁

and here's the whole friend group, all of them, no one left out 🫶

and that's the page, bestie 💖

cute little sign-off: this masterpiece lives in ./drivers/gpu/drm/amd/amdgpu, it's dated October 2026, and it's out here blessing the Kernel API Manual with its presence. go forth and start those rings responsibly, mwah 😘💅
