πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ’… radeon_ring_commit(9) β€” the Kernel API Manual era ✨

okay so bestie, welcome to the radeon_ring_commit(9) page from the Kernel API Manual, and honestly? it's short, it's sweet, it's giving "one job and she does it." let's get into it πŸŽ€


🌸 NAME 🌸

radeon_ring_commit β€” literally the function that tells the GPU to go execute the new commands sitting on the ring buffer. that's it, that's the whole vibe. she's the messenger πŸ¦‹


✨ SYNOPSIS ✨

void radeon_ring_commit (struct radeon_device *rdev , struct radeon_ring
*ring , bool hdp_flush );

copy it exactly like that if you're writing it out, okay? no cap, the commas and the spacing are on purpose πŸ™ˆ


πŸ’– ARGUMENTS πŸ’–

  • rdev β€” a radeon_device pointer, aka the "which radeon device are we even talking about" handshake πŸ‘‘
  • ring β€” the radeon_ring structure that's holding all the ring information. she's the one carrying the gossip πŸ“₯
  • hdp_flush β€” a bool that says whether or not to perform an HDP cache flush. yes or no bestie, pick one πŸ’…

πŸ”₯ DESCRIPTION πŸ”₯

okay so here's the whole plot: you update the wptr (the write pointer) to tell the GPU to execute the new commands on the ring buffer. that's the entire main character moment 🀩

and the little parenthetical at the end? "(all asics)" β€” meaning this works on every asic, no exceptions, no "well actually." periodt πŸ’€
