sdma_v5_0_emit_fill_buffer(9)

📦 version 7.3.1, in nixpkgs unstable

💅 sdma_v5_0_emit_fill_buffer — like, the kernel API manual page, bestie

okay so this is sdma_v5_0_emit_fill_buffer(9) from the Kernel API Manual and honestly? she's a small page but she SERVES. sit down, grab a strawberry drink 🍓, and lemme walk you through it.

✨ NAME ✨

sdma_v5_0_emit_fill_buffer — fill buffer using the sDMA engine 🫶

🎀 SYNOPSIS 🎀

void sdma_v5_0_emit_fill_buffer (struct amdgpu_ib *ib , uint32_t
src_data , uint64_t dst_offset , uint32_t byte_count );

that's it. that's the whole vibe. returns void, so no if (ret) energy here, she just does the thing 💅

🌸 ARGUMENTS 🌸

  • ib — indirect buffer to fill. yes bestie, the buffer that's doing the filling is itself a buffer. it's giving inception, it's giving main character energy 🌀
  • src_data — value to write to buffer. the actual juice 💖
  • dst_offset — dst GPU address. where on the GPU this whole thing lands 📍
  • byte_count — number of bytes to xfer. how much we're moving, no cap 📏

🦋 DESCRIPTION 🦋

Fill GPU buffers using the DMA engine (NAVI10). that's the whole description fr fr — she's concise, she's iconic, she doesn't over-explain herself 👑

ngl the manpage gives us exactly one line here and I'm not about to invent lore. NAVI10. DMA engine. buffers get filled. periodt. ✨

the whole friend group, in order, no one left out 🫶:

that's the whole page, bestie, you ate that 💅✨

sign-off era: this lil beauty lives in ./drivers/gpu/drm/amd/amdgpu, dated October 2026, and the header/footer keep it stamped as sdma_v5_0_emit_fill_buffer(9) — version 9, kernel API manual, iconic behavior only 🎀🌈💖
