dpaa2_io_irq(9)
π dpaa2_io_irq β like, the whole vibe
okay so bestie, welcome to the Kernel API Manual π β yes, we're doing kernel internals today, and yes, you're gonna slay it. This page is literally all about dpaa2_io_irq(9), an ISR for DPIO interrupts. Interrupt Service Routine. Very main character energy. β¨
πΈ NAME
dpaaa2_io_irq β no wait, dpaa2_io_irq π β it's the ISR for DPIO interrupts, fr fr. That's it, that's the whole name section. Short, iconic, to the point. π
β¨ SYNOPSIS
here's the signature bestie, presenting it exactly as-is, no edits, no cap:
irqreturn_t dpaa2_io_irq (struct dpaa2_io *obj );
like, that's the whole thing. she's cute, she's compact, she returns an irqreturn_t. π¦
π«Ά ARGUMENTS
objβ the given DPIO object. that's your one (1) input, bestie. the DPIO object in question. give her a little kiss on the forehead for me π
π DESCRIPTION
so what does she do? literally this:
Return IRQ_HANDLED for success, or IRQ_NONE if there were no pending interrupts.
that's the entire deal. two outcomes, no drama:
- stuff happened β
IRQ_HANDLEDβ slay - nothing was pending β
IRQ_NONEπ and that's totally fine
