pdc_interrupts_init(9)

💅 pdc_interrupts_init(9) 💅

okay so welcome to the Kernel API Manual, bestie — this is literally the page for pdc_interrupts_init(9), and it's giving “set up interrupts for a PDC” energy. No cap.

🌸 NAME 🌸

pdc_interrupts_init — Initialize the interrupt configuration for a PDC and specify a threaded IRQ handler for deferred handling of interrupts outside of interrupt context.

✨ SYNOPSIS ✨

int pdc_interrupts_init (struct pdc_state *pdcs );

🎀 ARGUMENTS 🎀

• pdcs — PDC state. That's it, bestie; it's the PDC state.

🦋 DESCRIPTION 🦋

okay so here's the vibe: Set the interrupt mask for transmit and receive done. Then Set the lazy interrupt frame count to generate an interrupt for just one pkt. Periodt. That's the whole description, and yes it's iconic.

🔥 RETURN 🔥

The page says: PDC_SUCCESS <0 if threaded irq request fails.
