πŸ’… drm_atomic_g...olorop_state β€” a Kernel API Manual moment

okay so bestie, welcome to the Kernel API Manual page for drm_atomic_g...olorop_state(9) β€” yes the name is doing a little ellipsis thing, we love an abbreviated icon ✨


🌸 NAME 🌸

drm_atomic_get_colorop_state β€” literally just get the colorop state, that's the whole job, no cap πŸ’–


πŸ¦‹ SYNOPSIS πŸ¦‹

struct drm_colorop_state * drm_atomic_get_colorop_state (struct
drm_atomic_commit *state , struct drm_colorop *colorop );

like, that's the whole signature, copy it exactly bestie 🫢


πŸŽ€ ARGUMENTS πŸŽ€

  • state β€” the global atomic state object. yes global, she's the main character of this whole operation πŸ‘‘
  • colorop β€” the colorop you want the state object for. that's the one. that's your girl πŸ’œ

πŸ”₯ DESCRIPTION πŸ”₯

So what does this function do?? It returns the colorop state for the given colorop β€” and if that state doesn't exist yet? it allocates it, because it's an icon and it handles things πŸ’…βœ¨

It also grabs the relevant plane lock to make sure that the state is consistent. gotta protect the vibe check, y'know? πŸ”’

What you get back is either:

  • the allocated state, or
  • the error code encoded into the pointer
⚠️ okay this part matters bestie: when the error is EDEADLK, the w/w mutex code has detected a deadlock and the entire atomic sequence must be restarted. like, the whole thing. start over. no shortcuts 😭

All other errors are fatal. not cute. not recoverable. fatal fr fr πŸ’€
