intel_irq_install(9)

💖 intel_irq_install(9) — NAME 💖

okay so welcome to the Kernel API Manual, bestie, because this page is all about intel_irq_install, and its whole name-brand purpose is that it enables the hardware interrupt. periodt. 💅

✨ SYNOPSIS ✨

int intel_irq_install (struct drm_i915_private *dev_priv );

🫶 ARGUMENTS 🫶

• dev_priv — i915 device instance. that's the whole assignment, bestie 🫶

🔥 DESCRIPTION 🔥

so what it does: it enables the hardware interrupt handling, but it leaves the hotplug handling still disabled. lowkey important. It gets called after intel_irq_init.

here's the vibe: in the driver load and resume code, we need working interrupts in a few places, but we do not want to deal with the hassle of concurrent probe and hotplug workers. hence the split into this two-stage approach. iconic, honestly. ✨
