🎀 dpu_core_irq_callback_handler(9) 🎀

okay bestie, welcome to the Kernel API Manual ✨ — yes that's the manual name, we're fancy here 💅 — and today's main character is dpu_core_irq_callback_handler, aka the little function that dispatches core interrupts. That's it, that's the whole gig. Iconic, lowkey, no notes 🫶.
