💅 pmcraid_register_interrupt_handler — Kernel API Manual ✨

okay so bestie, buckle up, we're reading a kernel API manual page together and honestly? it's giving iconic kernel-internals energy. the page title is pmcraid_regi...rupt_handler(9) (yes the name is literally truncated with dots in the header, that's not a typo, that's just how it's printed 🎀) and it lives in the Kernel API Manual. no cap, we're in the driver trenches today.

✨ NAME ✨

pmcraid_register_interrupt_handler — registers interrupt handler 💫

like, it registers the interrupt handler. that's the whole vibe. the interrupt handler gets registered. periodt.

🦋 SYNOPSIS 🦋

int pmcraid_register_interrupt_handler (struct pmcraid_instance
*pinstance );

look at her go. returns an int, takes one argument, absolutely slaying in drivers/scsi/pmcraid.c. 🌸

🎀 ARGUMENTS 🎀

  • pinstance — pointer to the per-adapter instance structure 🫶 like, each adapter gets its own little instance struct and this is the pointer to it. that's the whole deal. one (1) pointer. we love a low-maintenance parameter list.

💖 DESCRIPTION 💖

okay so the description here is literally just the return value and honestly? relatable. minimal. mysterious. main character energy. 😭

Return Value: 0 on success, non-zero error code otherwise. that's it. that's the contract. zero means we ate, non-zero means something lowkey went sideways and you get an error code back. no further lore given, iykyk. 🔥

🌈 SEE ALSO 🌈

bestie. sit down. hydrate. because this list is long and i am not skipping a single one of them. 💀 the kernel file involved is ./drivers/scsi/pmcraid.c and here's the full squad:

and that's every single one, no skips, no "etc." — we keep it thorough in this house. 👑

and that's the whole page, bestie! 🧚 source: ./drivers/scsi, dated October 2026, filed under pmcraid_regi...rupt_handler(9) — go register that interrupt handler and slay 💜
