sdma_v7_1_emit_fill_buffer(9)

📦 version 7.3.1, in nixpkgs unstable

🎀 NAME 🎀

So sdma_v7_1_emit_fill_buffer — straight outta the Kernel API Manual, bestie — is literally fill buffer using the sDMA engine. That's the whole assignment. Iconic.

✨ SYNOPSIS ✨

Here's the exact signature, no edits, no cap:

void sdma_v7_1_emit_fill_buffer (struct amdgpu_ib *ib , uint32_t
       src_data , uint64_t dst_offset , uint32_t byte_count );

It's void, so there's no return value to catch. Periodt.

🫶 ARGUMENTS 🫶

  • ib — indirect buffer to fill. Like, this is the buffer we're messing with, lowkey the main character.
  • src_data — value to write to buffer. The actual data bestie, the thing going in.
  • dst_offset — dst GPU address. That's the destination GPU address, fr fr.
  • byte_count — number of bytes to xfer. Yes, xfer. We're being fancy. 💅

💅 DESCRIPTION 💅

Fill GPU buffers using the DMA engine. That's the tea. That's the vibe. The sDMA engine is doing the fill-buffer thing, and this function is the call that makes it happen. Ngl, it's giving "short and powerful."
