πŸ’… intel_display_driver_resume_access ✨

okay so bestie, this is intel_display_driver_resume_access(9) β€” a kernel API manual page from the intel_display girlies, and she's literally the bouncer for display hardware access during resume. let's get into it πŸ’–


πŸŽ€ NAME πŸŽ€

intel_display_driver_resume_access β€” resume display HW access for the resume thread 🫢


✨ SYNOPSIS ✨

void intel_display_driver_resume_access (struct intel_display *display);

🌸 ARGUMENTS 🌸

  • display β€” the display device instance. that's your girl, the whole vibe check of a display device πŸ’…

πŸ¦‹ DESCRIPTION πŸ¦‹

okay so what this does is, it enables display HW access for the current resume thread β€” and like, only the current resume thread. every other (user) thread stays locked out, access disabled, not invited to the party πŸ™ˆ

examples of the kind of accesses we're talking about are modeset commits and connector probing. so like, real main-character hardware work.

the resume thread should only perform HW init programming (as in, the restoring modeset). that's the assignment, bestie, nothing else πŸ”₯

this function should be followed by calling intel_display_driver_enable_user_access, after you finish the HW init programming steps. like, you don't just leave it hanging, that's rude πŸ’€

✨ also important: this function should be called during system resume, before starting the HW init steps. timing matters, no cap.

πŸ’œ SEE ALSO πŸ’œ

like the whole access-control friend group, honestly. icons only πŸ‘‘
