bdw_update_pipe_irq(9)

💅 bdw_update_pipe_irq(9) — kernel API manual, section 9, bestie

Okay so picture this: you're deep in the i915 display code, section 9 of the kernel API manual, and you need to update a DE pipe interrupt. That's it. That's the whole vibe. This little icon is a void function, so it's not gonna hand you anything back — it just does the thing and dips. No cap. 🫶

✨ NAME ✨

bdw_update_pipe_irq — update DE pipe interrupt 🔥 (yes, "DE" like display engine, and yes, it's giving main character energy)

---

🌸 SYNOPSIS 🌸

void bdw_update_pipe_irq (struct intel_display *display , enum pipe pipe
, u32 interrupt_mask , u32 enabled_irq_mask );

She takes four arguments and returns literally nothing. void queen. 👑

---

🎀 ARGUMENTS 🎀

• display — the display device, bestie. That's the whole struct you're working on.
• pipe — the pipe whose interrupt you're updating. Like, which pipe. Be specific, she's not a mind reader. 💅
• interrupt_mask — mask of the interrupt bits to update. This is the "which ones are we even touching" mask.
• enabled_irq_mask — mask of the interrupt bits to enable. This is the "which ones get to be on" mask. ✨

Two masks, two jobs — don't mix them up, or it's gonna be a whole thing. 😭

🦋 SEE ALSO 🦋

• The kernel file itself, right here: ./drivers/gpu/drm/i915/display/intel_display_irq.c — go read the source, it's literally right there, iykyk 📖
• ilk_update_display_irq(9) — the older sibling
• bdw_update_port_irq(9) — the port-side cousin, same family energy
• ibx_display_interrupt_update(9) — the other interrupt-updating icon in this friend group

🌈 and that's the tea 🌈

Go forth and update those pipe interrupts, bestie. This page lives in ./drivers/gpu/drm/i915/display, it's dated October 2026, and it's chef's kiss — periodt. 💜🎀⭐
