💖 ilk_update_display_irq(9) 💖

okay so bestie, welcome to the Kernel API Manual, section 9 — this is the page for ilk_update_display_irq, and yes it's a whole vibe. it lives in the kernel docs, it's a function, and its entire personality is: update DEIMR. that's it. that's the name. iconic of it honestly 🎀

✨ NAME ✨

ilk_update_display_irq — updates DEIMR 💅

like, that's the whole job description. one (1) task. and she does it.

---

🌸 SYNOPSIS 🌸

void ilk_update_display_irq (struct intel_display *display , u32
       interrupt_mask , u32 enabled_irq_mask );

so it returns void (nothing back, she's not a gossip 💀), takes a struct intel_display *display, and then two u32 masks: interrupt_mask and enabled_irq_mask. three args, no drama, no cap 🫶

---

🦋 ARGUMENTS 🦋

• display — the display device, aka the main character of this whole operation 👑 this is the display you're messing with.
• interrupt_mask — mask of interrupt bits to update. lowkey the "which ones are we touching" list 💅
• enabled_irq_mask — mask of interrupt bits to enable. this is the "and which ones do we want actually on" list ⭐

two masks, one display, and the DEIMR gets updated. periodt.
