okay so bestie, welcome to the Kernel API Manual β¨ β this is the page for sdma_v7_0_r...ipeline_sync(9) (yes the title got cut off mid-word, that's just how the header rolls, no cap π«Ά). Sit down, hydrate, and let's get into it.
πΈ NAME πΈ
sdma_v7_0_ring_emit_pipeline_sync β literally just sync the pipeline π
β¨ SYNOPSIS β¨
void sdma_v7_0_ring_emit_pipeline_sync (struct amdgpu_ring *ring );
that's it. that's the whole vibe. one function, one arg, returns nothing (void, she doesn't give anything back, main character energy only π).
π¦ ARGUMENTS π¦
ringβ anamdgpu_ringpointer π«. that's the whole description, and honestly? iconic. she knows what she is.
π₯ DESCRIPTION π₯
Make sure all previous operations are completed (CIK) π β like, all of them, not just the ones you remembered to check. this is the "okay everybody stop, we're not moving until everyone's done" moment of the ring. it's giving group-chat-roll-call-before-we-leave. no cap.
ngl the (CIK) in there is doing a lot of heavy lifting β it's just part of the description as written, so we keep it exactly as-is, bestie. don't come for me π
π SEE ALSO π
the whole friend group π«Ά β plus the source file, which is the actual main character:
