✨ orc_interrupt(9) ✨

okay so bestie, welcome to the Kernel API Manual entry for orc_interrupt β€” like, the IRQ-processing girlie of the a100u2w world πŸ’… no cap, she's lowkey iconic.


🌸 NAME 🌸

orc_interrupt β€” IRQ processing πŸŽ€


πŸ¦‹ SYNOPSIS πŸ¦‹

irqreturn_t orc_interrupt (struct orc_host * host );

πŸ“ ARGUMENTS πŸ“

  • host β€” the host that's causing the interrupt, aka the main character of this whole situation πŸ‘‘

πŸ’– DESCRIPTION πŸ’–

So this function gets called from the IRQ handler, and she's protected by the host lock 🫢 like, she's safe, she's guarded, she's fine.

While the controller is reporting that there are scb's for processing, we pull them off the controller, turn the index into a host address pointer to the scb, and call the scb handler. The way that whole little pipeline just works?? obsessed ✨

Returns IRQ_HANDLED if any SCBs were processed, IRQ_NONE otherwise πŸ’€ (yeah, if nothing got done, you get the IRQ_NONE, that's just how it is, ngl).
