π NAME π
sdma_v6_0_ring_emit_hdp_flush β bestie, this is the one that emits an hdp flush on the DMA ring β¨
So like, the manual page name got all squished in the header (sdma_v6_0_r...it_hdp_flush(9)) because terminal widths are rude, but we move π
β it's from the Kernel API Manual, and yes it's a whole kernel thing, don't worry, I got you π«Ά
β¨ SYNOPSIS β¨
void sdma_v6_0_ring_emit_hdp_flush (struct amdgpu_ring *ring );
Lowkey the whole vibe of this function in one line: it returns void (so no return value to obsess over), it's called sdma_v6_0_ring_emit_hdp_flush, and it takes exactly one thing: a struct amdgpu_ring * named ring π
π¦ ARGUMENTS π¦
ringβ amdgpu ring pointer. That's it. That's the whole argument. One (1) ring pointer, main character energy, no notes π
πΈ DESCRIPTION πΈ
Emit an hdp flush packet on the requested DMA ring π«
That's literally the assignment, fr fr β you hand it the ring you want, and it emits the hdp flush packet on that DMA ring. Nothing sketchy, nothing extra, no cap π
π SEE ALSO π
Kernel file ./drivers/gpu/drm/amd/amdgpu/sdma_v6_0.c β that's the actual home of this whole family, go say hi π

That's the whole page, babe. Source/version lives at ./drivers/gpu/drm/amd/amdgpu, it's dated October 2026, and this cutie was brought to you by the kernel docs β mwah, go emit some flushes responsibly π
