cik_ring_ib_execute(9)

💅 cik_ring_ib_execute(9) — straight out of the Kernel API Manual ✨

okay bestie, this one's from the Kernel API Manual and it's lowkey a whole vibe — we're emitting an IB on the gfx ring. let me put you on 💖

---

🌸 NAME 🌸

cik_ring_ib_execute — emit an IB (Indirect Buffer) on the gfx ring 🎀

---

✨ SYNOPSIS ✨

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

---

🦋 ARGUMENTS 🦋

• rdev — a radeon_device pointer, bestie. that's the device handle, the main character of the whole story 👑
• ib — a radeon indirect buffer object 🎀

---

💜 DESCRIPTION 💜

so what it does: it emits a DE (drawing engine) or a CE (constant engine) IB on the gfx ring 🔥

and like, where do these IBs even come from? usually userspace acceleration drivers generate them and then submit them to the kernel so the kernel can schedule them on the ring. iykyk ✨

this function's whole job is literally that: it schedules the IB on the gfx ring for execution by the GPU 💅 periodt.
