📦 version 7.3.1, in nixpkgs unstable

💅 amdgpu_multi_ring_reset_helper_end — a Kernel API Manual page, bestie edition 🎀

okay so this is from the Kernel API Manual, section 9, and we're talking about amdgpu_multi_ring_reset_helper_end. yes the name is a mouthful, no we're not changing it, it's iconic actually. ✨

🌸 NAME 🌸

amdgpu_multi_ring_reset_helper_end — get multiple rings ready for a reset. that's the whole vibe. 🔥

🦋 SYNOPSIS 🦋

int amdgpu_multi_ring_reset_helper_end (const u32 ring_type_mask ,
struct amdgpu_ring *guilty_ring , int ret );

that's the whole signature, copy it exactly, do not freestyle it, i'm begging 🫶

⭐ ARGUMENTS ⭐

  • ring_type_mask — a const u32 bitmask of the ring types that are affected. it's giving "which ones, specifically". 👑
  • guilty_ring — a struct amdgpu_ring * pointing at the ring that's guilty of causing the reset. yes, guilty, the kernel is calling it out by name, no cap 💀
  • ret — the return code from the reset function. just hand over whatever you got. 🙈

💖 DESCRIPTION 💖

so here's the tea: after you've called amdgpu_multi_ring_reset_helper_begin and you've actually executed the real reset method, you call this function to restore normal operation. it's the "ok we're done, everybody back to your seats" moment. 🌈

and listen — if the reset failed, you should still call this function. yes, even then. it restores the preemption state regardless, but it will not attempt to fully restore the ring contents. the way that's literally the whole distinction, iykyk. ⚠️

so fr fr: failed reset = still call it. it just won't go all the way on the ring contents. don't skip it. 🚨

🧚 SEE ALSO 🧚

the kernel file lives at ./drivers/gpu/drm/amd/amdgpu/amdgpu_ring.c, and here's the whole squad, all of them, no skipping:

like, the whole friend group showed up. obsessed. 💜

and that's the page!! 💅 shoutout to ./drivers/gpu/drm/amd/amdgpu, dated October 2026, out here serving amdgpu_multi...t_helper_end(9) realness. mwah, slay, go reset those rings responsibly. 🍓🎀🦋
