cik_sdma_sem...re_ring_emit(9)

📦 version 7.3.1, in nixpkgs unstable

💖 NAME 💖

cik_sdma_semaphore_ring_emit — emit a semaphore on the dma ring. Yes bestie, this is the Kernel API Manual page cik_sdma_sem...re_ring_emit(9), and it's literally about putting a semaphore packet on the dma ring. ✨

🦋 SYNOPSIS 🦋

bool cik_sdma_semaphore_ring_emit (struct radeon_device *rdev , struct
       radeon_ring *ring , struct radeon_semaphore *semaphore , bool emit_wait
       );

🎀 ARGUMENTS 🎀

  • rdev — a radeon_device pointer. That's the device pointer, bestie.
  • ring — the radeon_ring structure holding ring information. It's giving ring-info holder energy.
  • semaphore — a radeon semaphore object. 🌸
  • emit_wait — wait or signal semaphore. Yep, that's the bool's whole job.

✨ DESCRIPTION ✨

Okay so this one adds a DMA semaphore packet to the ring, and it waits on or signals other rings (CIK). That's the vibe: ring packet goes in, semaphore does its wait-or-signal thing. 💅
