💅 qla4_82xx_interrupt_service_routine — NAME

ok so this is a page from the Kernel API Manual, and it's all about qla4_82xx_interrupt_service_routine — aka the isr 🎀 (that's short for interrupt service routine, iykyk).

✨ SYNOPSIS ✨

void qla4_82xx_interrupt_service_routine (struct scsi_qla_host *ha ,
       uint32_t intr_status );

like... that's the whole signature bestie, isn't it gorgeous 🫶

🧚 ARGUMENTS 🧚

• ha — pointer to the host adapter structure. literally just a pointer to your host adapter, no biggie 💖
• intr_status — Local interrupt status/type. it's the local interrupt status slash type, both vibes in one field 😌

🔥 DESCRIPTION 🔥

okay so listen. this is the main interrupt service routine, the headliner, the main character energy of the interrupt world 👑

the hardware_lock is locked upon entry — so by the time you're in here, that lock is already held. noted. locked. slay.

and it runs in interrupt context. yes bestie, that interrupt context. be normal about it, don't go doing sleepy-blocking things in there 🙈

ngl, interrupt context is not the place for a nap — no cap, keep it snappy.
