💖 cayman_dma_ring_ib_execute(9) 💖

okay so bestie, we're in the Kernel API Manual today and this page is literally about cayman_dma_ring_ib_execute — say it with me, it's a mouthful, but she's iconic. This is the one that schedules an IB on the DMA engine. No cap. 🎀

✨ NAME ✨

cayman_dma_ring_ib_execute — schedule an IB on the DMA engine 🦋

🌸 SYNOPSIS 🌸

void cayman_dma_ring_ib_execute (struct radeon_device *rdev , struct
radeon_ib *ib );

like, that's the whole signature. void in, void out, no return value, she just does the thing. periodt. 💅

🫶 ARGUMENTS 🫶

  • rdev — a radeon_device pointer, i.e. your whole entire GPU situation in one struct. main character energy fr. ⭐
  • ib — the IB object you want to schedule. this is the actual thing getting queued up, so don't lose her. 💀

🔥 DESCRIPTION 🔥

Schedule an IB in the DMA ring (cayman-SI). 🎀

that's it, that's the vibe — you hand her the rdev and the ib, and she puts that IB in the DMA ring for cayman-SI hardware. lowkey elegant, highkey doing a lot of work behind the scenes. no extra caveats, no warnings, no drama — just scheduling. slay. ✨

like, the way they all showed up for each other 😭💜

and that's the page!! 🧚 it lives in ./drivers/gpu/drm/radeon, dated October 2026, and it's page cayman_dma_ring_ib_execute(9) of the Kernel API Manual — go forth and schedule those IBs, bestie, iykyk 💖🌸🎀
