💾 radeon_ring_backup(9) — the kernel API manual, bestie edition 🎀

okay so picture this: it's radeon_ring_backup, straight out of the Kernel API Manual, and she is literally the "save your progress before the boss fight" of the Radeon driver. no cap. let's get into it 💅

✨ NAME ✨

radeon_ring_backup — Back up the content of a ring

like, the whole ring. all of it. she's a backup girlie 🫶

✨ SYNOPSIS ✨

unsigned radeon_ring_backup (struct radeon_device *rdev , struct
radeon_ring *ring , uint32_t **data );

three args in, one unsigned out. that's the whole vibe check 👑

✨ ARGUMENTS ✨

  • rdev — a radeon_device pointer. the main character, fr 👑
  • ring — the ring we want to back up. yes, that ring 💫
  • data — placeholder for returned commit data. she's holding a spot for the data to come back to, iconic behavior 🎀

✨ DESCRIPTION ✨

Saves all unprocessed commits from a ring, and returns the number of dwords saved.

that's it. that's the whole thing. she scoops up every commit that hasn't been processed yet, tucks them somewhere safe, and hands you back a count of dwords like "here's how much I just saved bestie, ur welcome" 😭💖

ngl this is the "not me saving the state of the universe before anything goes sideways" function and honestly? obsessed. lowkey essential. highkey underrated. periodt.

🌈 SEE ALSO 🌈

lowkey reminder: radeon_ring_backup(9) saves unprocessed commits and returns the dword count — that's the entire contract, don't go inventing extra lore for her 💀
