radeon_fence...r_start_ring(9)

📦 version 7.3.1, in nixpkgs unstable

💖 NAME 💖

radeon_fence_driver_start_ring — bestie, this is the one that makes the fence driver ready for use on the ring you asked for ✨

Quick vibe check first: this page lives in the Kernel API Manual, and it's giving "low-level radeon GPU internals, but make it cute" 🦋

🌸 SYNOPSIS 🌸

int radeon_fence_driver_start_ring (struct radeon_device *rdev , int ring );

🎀 ARGUMENTS 🎀

  • rdev — the radeon device pointer, aka your main character 🫶
  • ring — the ring index you wanna start the fence driver on, no cap 💅

✨ DESCRIPTION ✨

Okay so here's the tea ☕: this function gets the fence driver ready for processing — and like, on all asics, periodt 💯.

But not every asic has every ring, right? So obviously each asic is only gonna start the fence driver on the rings it actually has 🙈 — nobody's out here starting drivers on rings that don't exist, that's not the vibe.

It returns 0 for success, and returns errors for failure 😭 (so like, check your return value, bestie, fr fr).

🔥 SEE ALSO 🔥

The source lives in the kernel file ./drivers/gpu/drm/radeon/radeon_fence.c — go binge it, it's iconic 👑

Also the whole fence friend group 💜:

Lowkey mandatory: read the fence family before you touch anything — iykyk 🧚

And that's the whole page, bestie 🌈. Shoutout to ./drivers/gpu/drm/radeon for the source, October 2026 for the date, and the Kernel API Manual for hosting this absolute gem 💖 Slay, and remember: start the fence driver only on the rings your asic actually has. Periodt. 👑
