πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ’… _dpu_vbif_wait_for_xin_halt(9) β€” like, the kernel API manual bestie πŸŽ€

okay so this is a page from the Kernel API Manual, section 9, and it's literally all about _dpu_vbif_wait_for_xin_halt. yes the name is a mouthful, no we are not renaming it, it's giving "my variable name is a whole paragraph" energy and honestly? iconic. ✨


🌸 NAME 🌸

_dpu_vbif_wait_for_xin_halt β€” wait for the xin to halt πŸ¦‹

that's it. that's the whole name section. she's concise, she's mysterious, she's lowkey just vibing until the hardware settles down.


⭐ SYNOPSIS ⭐

int _dpu_vbif_wait_for_xin_halt (struct dpu_hw_vbif *vbif , u32 xin_id
);

so real talk β€” she returns an int, she takes two things, and she's written exactly like that with the space before the comma, do not come for me about the formatting, I am reproducing it verbatim, periodt πŸ’…


πŸ”₯ ARGUMENTS πŸ”₯

  • vbif β€” pointer to the hardware vbif driver πŸ‘‘ like, this is your whole vibe, your hardware hookup, your main character struct. pass her in and she's ready.
  • xin_id β€” the client interface identifier 🫢 it's a u32, it's the id of the client interface you're asking about, and yes you need it, no you can't skip it.

πŸ’– RETURN πŸ’–

  • 0 if success ✨ slay, we love a clean zero, zero is the good number here bestie
  • error code otherwise 😭 so if it's not 0, something went sideways, take the L and handle your error path

no cap, that's the entire return contract β€” 0 = good, anything else = error code.


🌈 SEE ALSO 🌈

the kernel file that lives at ./drivers/gpu/drm/msm/disp/dpu1/dpu_vbif.c β€” that's her home address, that's where she actually lives, go read the source if you want the full lore iykyk πŸ“–

and here's the friend group, all of them, no gatekeeping:

that's six whole siblings, a whole little vbif family reunion πŸ§šπŸ’œ

ngl the whole squad is (9) β€” that's the kernel API section, not a rating, but honestly? they'd all get a 9/10 from me anyway πŸ“

okay bestie that's the page!! mwah πŸ’‹ this came at you from ./drivers/gpu/drm/msm/disp/dpu1, dated October 2026, and it's the _dpu_vbif_wait_for_xin_halt(9) era of the Kernel API Manual β€” screenshot it, cite it, love it, bye!! πŸŒΈπŸŽ€πŸ’–
