💖 radeon_fence_emit(9) 💖

okay so bestie, welcome to the kernel API manual for radeon_fence_emit(9) — yes it's a section 9 page, yes it's a function, no you don't have to be scared of it. it's literally just "put a fence on a ring" energy and honestly? iconic. 🎀

✨ NAME ✨

radeon_fence_emit — emit a fence on the requested ring 🦋

like that's it. that's the whole job. it puts a fence down on whichever ring you point at. slay.

🌸 SYNOPSIS 🌸

int radeon_fence_emit (struct radeon_device *rdev , struct radeon_fence
**fence , int ring );

copy it exactly like that, no cap, don't @ me about the spacing. 💅

🎀 ARGUMENTS 🎀

  • rdev — a radeon_device pointer. it's the radeon device, your main character of the operation 👑
  • fence — a radeon fence object. this is the fence we're talking about, the whole point of the function, the moment 💫
  • ring — the ring index that the fence is associated with. which ring? that ring. you tell it. 🌀

🔥 DESCRIPTION 🔥

so, what does it do? it emits a fence command on the requested ring — and yeah, that goes for all asics, so no weird per-generation exceptions to worry about, periodt. 🫶

return value check, because we love a clear contract:

  • returns 0 on success — you ate, no notes ✨
  • returns -ENOMEM on failure — the memory said "not today bestie" 😭
no cap: that's literally the entire documented behaviour. anything else you think it does is a rumour, and we don't do rumours here 🙈
