_base_check_enable_msix(9)

📦 version 7.3.1, in nixpkgs unstable

🌸 _base_check_enable_msix (9) — Kernel API Manual, bestie edition 🌸

okay so this page is from the Kernel API Manual, and it's all about one little function in the kernel's SCSI/mpt3sas corner of the world. she's lowkey niche but she MATTERS, iykyk 💅

✨ NAME ✨

_base_check_enable_msix — checks MSIX capabable.

(no that's not a typo on my end bestie, that's literally what it says, and honestly? iconic of it 😭)

🦋 SYNOPSIS 🦋

int _base_check_enable_msix (struct MPT3SAS_ADAPTER *ioc );

like… the whole vibe in literally two lines. she takes one pointer and returns an int, periodt. 💖

🎀 ARGUMENTS 🎀

  • ioc — per adapter object ✨ (that's the struct MPT3SAS_ADAPTER *, aka the whole personality of the adapter you're poking at)

🌈 DESCRIPTION 🌈

okay so what does she actually DO. the manpage says it very plainly and we're not gonna add ✨lore✨ that isn't there: this function checks to see if the card is capable of MSIX, and sets the number of available msix vectors. that's it. that's the assignment, and she ate. 👑

so like — vibe check on the card first (can you do MSI-X, bestie?), then the count of available msix vectors gets set. two little jobs, one function, no cap. 🫶

ngl the manpage is extremely short on this one — there's no return-value section, no error section, no extra notes. so we're not inventing any, fr fr. what you see above is the whole story. 🙈

⭐ SEE ALSO ⭐

this list is a WHOLE group chat and honestly I'm obsessed. every single one of these is in the (9) section of the Kernel API Manual, and the first entry is literally the kernel file it lives in:

Kernel file ./drivers/scsi/mpt3sas/mpt3sas_base.c

also note: _base_wait_on_iocstate(9) and _base_wait_for_iocstate(9) both show up in that list, and no I'm not merging them, they're two whole different besties, look at the names. 💀

and that's the whole page, bestie!! 🧚 this cutie lives under ./drivers/scsi/mpt3sas, the manual is dated October 2026, and that's the Kernel API Manual energy — go read the source file if you want the ✨full lore✨, this page is just the little intro. mwah 💖🎀🦋
