💅 qla4xxx_interrupt_service_routine(9) 💅

okay so bestie, welcome to the Kernel API Manual, section 9 — this is the lil page about qla4xxx_interrupt_service_routine, and honestly? it's kind of a big deal. let's get into it 🎀

✨ NAME ✨

qla4xxx_interrupt_service_routine — the isr. that's it, that's the whole name. short, sweet, iconic. 👑

🦋 SYNOPSIS 🦋

void qla4xxx_interrupt_service_routine (struct scsi_qla_host * ha ,
       uint32_t intr_status );

like, look at that signature. she's serving. no return value because she doesn't need one, she just does things. 💅

🌸 ARGUMENTS 🌸

  • ha — a pointer to the host adapter structure. yes bestie, the whole adapter, right there in your hands 🫶
  • intr_status — the local interrupt status/type. it's telling you what kind of interrupt situation we're in, so pay attention fr fr ⭐

💖 DESCRIPTION 💖

so here's the tea: this is the main interrupt service routine. the headliner. main character energy, no cap. 🔥

two things you literally cannot forget, bestie:

  • hardware_lock is already locked upon entry — so don't you dare go grabbing it again, it's handled 🙈
  • it runs in interrupt context — like, you are in the interrupt right now. act accordingly. no sleeping, no nonsense, just vibes and speed 💀
ngl this is not the place to be doing slow, cute, leisurely work. interrupt context is a vibe check and you gotta pass it. ⚡

🌈 SEE ALSO 🌈
