sdma_v5_0_r...it_hdp_flush(9)

📦 version 7.3.1, in nixpkgs unstable

💅 NAME 💅

ok so bestie, this one is sdma_v5_0_ring_emit_hdp_flush — it emits an hdp flush on the DMA ring. that's the whole vibe. it's a Kernel API Manual page, and like… it's giving "small function, big responsibilities" ✨

🌸 SYNOPSIS 🌸

void sdma_v5_0_ring_emit_hdp_flush (struct amdgpu_ring *ring );

it returns void, so nothing comes back out — it just does the thing to the ring you hand it. no notes. periodt. 🫶

🎀 ARGUMENTS 🎀

  • ring — an amdgpu ring pointer. that's your ring, your main character. you pass it in and the function does its little flush dance on it. 🦋

✨ DESCRIPTION ✨

so what it actually does: it emits an hdp flush packet on the DMA ring you asked for. "requested DMA ring" — meaning the one you handed over in ring. that's it, that's the plot 💖

like, genuinely no cap, this is a one-job function and it does that one job. no extra lore, no secret options, nothing hidden. it slays in the most straightforward way possible 👑

🔥 SEE ALSO 🔥

the kernel file lives right here, bestie:

  • ./drivers/gpu/drm/amd/amdgpu/sdma_v5_0.c

and the whole friend group (iykyk):

and that's the whole page, bestie 🧚 this little icon dropped from ./drivers/gpu/drm/amd/amdgpu in October 2026 — go forth and flush those hdp's, mwah 💜
