💅 intel_displa..._user_access(9) 💅

okay bestie so you're in the Kernel API Manual and we're about to talk about intel_display_driver_disable_user_access — yes that's a long name, yes she's iconic, we move 💖

✨ NAME ✨

intel_display_driver_disable_user_access — literally just turns off display HW access for user threads. that's it. that's the girlie.

🦋 SYNOPSIS 🦋

void intel_display_driver_disable_user_access(struct intel_display *display);

🌸 ARGUMENTS 🌸

  • display — the display device instance 🫶 like, the actual display thing you're working on

👑 DESCRIPTION 👑

so what she does is disable the display HW access for user threads. user threads, bestie — the normal ones. examples of the kind of access we're talking about are modeset commits and connector probing. iykyk 🔥

but here's the twist: for the current thread, the access is still enabled. and that's on purpose — the current thread should only perform HW init/deinit programming. think the initial modeset during driver loading, or the disabling modeset during driver unloading and system suspend/shutdown. no cap, that's the whole vibe ✨

so this function should be followed by calling either:

  • intel_display_driver_enable_user_access after you finish the HW init programming, or
  • intel_display_driver_suspend_access after you finish the HW deinit programming

pick one, bestie, don't leave her hanging 💀

💜 also important: call this function during driver loading/unloading and system suspend/shutdown, and do it before you start the HW init/deinit programming. order matters, fr fr.
