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 π
π NAME π
intel_display_driver_resume_access β resume display HW access for the resume thread π«Ά
β¨ SYNOPSIS β¨
void intel_display_driver_resume_access (struct intel_display *display);
πΈ ARGUMENTS πΈ
displayβ the display device instance. that's your girl, the whole vibe check of a display device π
π¦ DESCRIPTION π¦
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 π
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 π₯
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 π
β¨ also important: this function should be called during system resume, before starting the HW init steps. timing matters, no cap.

this lil masterpiece lives in ./drivers/gpu/drm/i915/display, dated October 2026, and it's giving kernel documentation but make it cute. mwah π go forth and resume responsibly, bestie π§ββοΈπ
