mpt3sas_get_sdev_by_addr(9)

📦 version 7.3.1, in nixpkgs unstable

omg hi bestie!! okay so this is a page from the Kernel API Manual (section 9, the kernel functions era 🧚) and it's all about one lil function called mpt3sas_get_sdev_by_addr. it's short, it's sweet, it's giving "I just wanna find a device" energy. let's get into it 💅

✨ NAME ✨

mpt3sas_get_sdev_by_addr — sas device search

like, literally a sas device search. that's the whole vibe. no cap.

🦋 SYNOPSIS 🦋

struct _sas_device * mpt3sas_get_sdev_by_addr (struct MPT3SAS_ADAPTER
*ioc , u64 sas_address , struct hba_port *port );

so it hands you back a struct _sas_device * — a pointer to a sas device object — and it takes three things to do it. iconic signature, honestly 🎀

🌸 ARGUMENTS 🌸

  • ioc — the per adapter object 💜 like, the whole controller's main character. everything lives under here.
  • sas_address — the sas address 👑 this is the u64 baddie you're searching for, it's literally the address, that's the whole point.
  • port — the hba port entry 🫶 a struct hba_port *, the port situation you're matching against.

⭐ CONTEXT ⭐

okay bestie this part is important, don't skip it!! the calling function should acquire ioc->sas_device_lock 🔒 like, you gotta hold that lock before you call this. this is not optional-coded, this is a real requirement. lock it up fr fr.

🔥 DESCRIPTION 🔥

so what does it actually do? it searches for a sas_device based on the sas_address & the port number, and then returns the sas_device object. that's it. that's the whole function. it's a lookup girlie. she finds, she returns, she leaves 💅✨

🌈 SEE ALSO 🌈

okay this list is LONG and honestly kind of a serve — it's the kernel file ./drivers/scsi/mpt3sas/mpt3sas_scsih.c and everyone it hangs out with. every single one, in order, because nobody gets left out 💖:

like… that's the whole friend group 😭💖 every single one of them showed up to the party.

and that's the page!! shoutout to the source path ./drivers/scsi/mpt3sas and the date stamp October 2026 — that's the footer energy, we're just folding it in at the end like a little signature at the bottom of a note 🎀✨ ily, go lock your mutex, bye!! 🌸🦋💜
