sdma_v5_2_r...it_hdp_flush(9)

💖 NAME 💖

okay so bestie, this is the sdma_v5_2_ring_emit_hdp_flush(9) page from the Kernel API Manual, and the whole assignment is: sdma_v5_2_ring_emit_hdp_flush — emit an hdp flush on the DMA ring. That's it. That's the main character. ✨

✨ SYNOPSIS ✨

void sdma_v5_2_ring_emit_hdp_flush (struct amdgpu_ring *ring );

Literally the signature, no cap. The return type is void, and it takes a struct amdgpu_ring *ring.

🎀 ARGUMENTS 🎀

• ring — amdgpu ring pointer. That's the one (1) argument, bestie. She's a pointer to an amdgpu ring, and that's the whole story. 💅

🦋 DESCRIPTION 🦋

Emit an hdp flush packet on the requested DMA ring. That's the assignment, and it ate. 🔥 No extra lore on this page — just a packet, a DMA ring, and a dream. 🫶
