intel_displ...spend_access(9)

💖 NAME 💖

intel_display_driver_suspend_access — bestie, this one suspends display HW access for all threads, no cap 🫶

also hi, welcome to the Kernel API Manual, section 9, the page literally titled intel_displ...spend_access(9) (yes the title is truncated, she's a little mysterious like that 💅)

---

✨ SYNOPSIS ✨

void intel_display_driver_suspend_access (struct intel_display *display );

---

🎀 ARGUMENTS 🎀

• display — the display device instance. that's the vibe check right there 🦋

---

🌸 DESCRIPTION 🌸

okay so the whole point: this function disables the display HW access for all threads. all of them. everybody. collectively ✨

examples of the kinds of accesses we're talking about are modeset commits and connector probing 🔥

the way this works: this call should be either followed by calling intel_display_driver_resume_access, or the driver should be unloaded/shutdown. like, pick a lane, bestie 😭 don't just leave it hanging.

fr fr, this function should be called during driver unloading and system suspend/shutdown, and specifically after completing the HW deinit programming 👑 so like, order matters, do not skip ahead bestie
