💅 cik_sdma_ring_ib_execute — from the Kernel API Manual, bestie ✨

Okay so picture this: you're deep in the kernel, the vibes are immaculate, and you need to schedule an IB on the DMA engine. That's literally this function. Welcome to the group chat 👑

🌸 NAME 🌸

cik_sdma_ring_ib_execute — the one that schedules an IB on the DMA engine. No cap, that's the whole personality.

✨ SYNOPSIS ✨

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

It's giving void, it's giving two struct pointers, it's giving zero return value because it doesn't need one 💁‍♀️

🎀 ARGUMENTS 🎀

  • rdev — a radeon_device pointer 🫶 your whole GPU situation lives in here
  • ib — the IB object you wanna schedule 🌈 like, the actual thing getting queued up

🦋 DESCRIPTION 🦋

Schedule an IB in the DMA ring (CIK). That's it. That's the function. Short queen behavior, honestly 💜

Think of it as the hand-off moment: the IB walks in, the DMA ring says "hey bestie", and the scheduling happens. Main character energy for real 🔥

Lowkey the whole CIK SDMA squad is here and they all ate 💅 go read them, iykyk.

Okay that's the page, bestie — this little manual moment came out of ./drivers/gpu/drm/radeon, dated October 2026, and it goes by cik_sdma_ring_ib_execute(9). Periodt. 🍓💖
