mv_interrupt(9)

💅 NAME 💅

mv_interrupt(9) — from the Kernel API Manual, bestie, and this is the Main interrupt event handler. She's the one checking the interrupt vibe and making sure the pending stuff gets handled. 👑

✨ SYNOPSIS ✨

irqreturn_t mv_interrupt (int irq , void *dev_instance );

🎀 ARGUMENTS 🎀

• irq — unused. Not me looking at an argument that's literally just chilling. 💀
• dev_instance — private data; in this case, the host structure. Slay, context. 🫶

🦋 DESCRIPTION 🦋

Okay so the move here is: read the read only register to determine if any host controllers have pending interrupts. If so, call the lower level routine to handle them. Also check for PCI errors, because those are only reported here — highkey important, don't skip that vibe check. 🔥

LOCKING: This routine holds the host lock while processing pending interrupts. So yeah, she's locked in while she works. 🔒
