πŸ’– NAME πŸ’–

sdma_v6_0_ring_emit_hdp_flush β€” bestie, this is the one that emits an hdp flush on the DMA ring ✨

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 πŸ’… β€” it's from the Kernel API Manual, and yes it's a whole kernel thing, don't worry, I got you 🫢


✨ SYNOPSIS ✨

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 πŸŽ€


πŸ¦‹ ARGUMENTS πŸ¦‹

  • ring β€” amdgpu ring pointer. That's it. That's the whole argument. One (1) ring pointer, main character energy, no notes πŸ‘‘

🌸 DESCRIPTION 🌸

Emit an hdp flush packet on the requested DMA ring πŸ’«

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 🌈
