💅 sdma_v4_4_2...it_hdp_flush(9)

okay bestie, welcome to the Kernel API Manual, section 9 — yes, the big-league kernel function pages, we love her 💖. This one's about sdma_v4_4_2_ring_emit_hdp_flush, and honestly? her name is longer than my attention span but she's lowkey iconic.

✨ NAME ✨

sdma_v4_4_2_ring_emit_hdp_flush — emit an hdp flush on the DMA ring 🌀

like, that's literally the whole job. she emits. she flushes. she goes home. periodt.

🌸 SYNOPSIS 🌸

void sdma_v4_4_2_ring_emit_hdp_flush (struct amdgpu_ring *ring );

no return value, no drama — she's a void girlie, she just does the thing and dips 🫶

🎀 ARGUMENTS 🎀

  • ring — amdgpu ring pointer 💫 (this is the ring bestie, the actual one you want flushed. keep her safe, keep her valid, don't be weird about it)

🦋 DESCRIPTION 🦋

So the vibe is: you hand her a DMA ring, and she emits an hdp flush packet on the requested DMA ring ✨. That's it. That's the whole function. She shows up, drops the packet on the ring you asked for, and leaves. main character energy, zero small talk 💅

not me being obsessed with a function that's two sentences long — but honestly? same 🍓

this lil cutie lives in ./drivers/gpu/drm/amd/amdgpu, she's stamped October 2026, and she reps the Kernel API Manual at section 9 — catch her there whenever, she's not going anywhere 🎀✨
