💖 sdma_v6_0_emit_fill_buffer(9) 💖

okay bestie, welcome to the Kernel API Manual page for sdma_v6_0_emit_fill_buffer — yes, the title is a whole mouthful, but we’re gonna slay it. This is the function that fills buffers using the sDMA engine. ✨

🌸 NAME 🌸

sdma_v6_0_emit_fill_buffer — fill buffer using the sDMA engine

✨ SYNOPSIS ✨

void sdma_v6_0_emit_fill_buffer (struct amdgpu_ib *ib , uint32_t
       src_data , uint64_t dst_offset , uint32_t byte_count );

🎀 ARGUMENTS 🎀

• ib — the indirect buffer to fill 💅
• src_data — the value to write to buffer ✨
• dst_offset — dst GPU address 🎯
• byte_count — number of bytes to xfer 🚚

🦋 DESCRIPTION 🦋

Fill GPU buffers using the DMA engine. That’s the whole vibe: DMA engine goes brrr and the GPU buffer gets filled. no cap. 💖
