πŸ¦‹ ARGUMENTS πŸ¦‹

  • ring β€” an amdgpu ring pointer. that's your one (1) input, bestie. the whole function runs on this. πŸ‘‘

πŸ’œ DESCRIPTION πŸ’œ

that's the whole page, no crumbs left πŸ’– this one lives in ./drivers/gpu/drm/amd/amdgpu, dated October 2026, in the Kernel API Manual β€” and yeah, the footer literally spells the function name all truncated like sdma_v4_0_pa...ing_get_wptr(9) because even the manpage header needs its beauty filter. periodt. πŸŽ€βœ¨πŸ’€
