mpi3mr_create_tgtdev(9)

📦 version 7.3.1, in nixpkgs unstable

💖 NAME 💖

ok so like — mpi3mr_create_tgtdev — bestie, this is the one that creates a target device and adds it to the list. the whole "make it exist and then put it in the group chat" vibe 💅

this page lives in the Kernel API Manual, and it's for all you driver girlies out there 🫶

✨ SYNOPSIS ✨

int mpi3mr_create_tgtdev (struct mpi3mr_ioc *mrioc , struct
mpi3_device_page0 *dev_pg0 );

like, that's the whole signature. no cap. 🎀

🌸 ARGUMENTS 🌸

  • mrioc — the Adapter instance reference, aka your little handle to the controller. you know her, you love her 💖
  • dev_pg0 — the Device Page 0 data. this is the actual info about the device, iykyk 🦋

🦋 DESCRIPTION 🦋

okay so here's the tea ☕ — this function does a little vibe check first:

  • if the device (the one specified by the device page 0 data) is not present in the driver's internal list → it allocates the memory for the device, populates the data, and adds it to the list. boom, she's iconic, she's on the list 👑✨
  • else → it just updates the device data. no new entry, just a glow-up 💅

and the key for all of this? the persistent ID 🔑 like, that's how she's identified, periodt.

🔥 RETURN 🔥

  • 0 on success — slay 💯
  • -ENOMEM on memory allocation failure — 😭 the allocator said no, fr fr

🎀 SEE ALSO 🎀

girl, buckle in, because the reference list here is long and honestly kind of iconic for it 💀

and all of these besties:

like, that's a lot of cross-references but we don't gatekeep here 💜 read them all, bestie, they're all part of the family 🫶

and that's the whole page, babes 🌈 this little gem comes from ./drivers/scsi/mpi3mr and it's dated October 2026 — so go forth, create those target devices, and remember: persistent ID is the key 🔑✨💖
