mpt3sas_bas...re_processor(9)

💅 `mpt3sas_base_scsi_enclosure_processor` 💅

okay bestie, welcome to the Kernel API Manual, mpt3sas edition ✨ this one's a lil function that talks to your enclosure. it's giving "middle management for LEDs" and honestly? iconic.

✨ NAME ✨

mpt3sas_base_scsi_enclosure_processor — sending request to sep device 🎀

("sep" = SCSI Enclosure Processor, iykyk)

🌸 SYNOPSIS 🌸

int mpt3sas_base_scsi_enclosure_processor (struct MPT3SAS_ADAPTER *ioc ,
Mpi2SepReply_t *mpi_reply , Mpi2SepRequest_t *mpi_request );

three params, one int out the door. slay 💅

🎀 ARGUMENTS 🎀

ioc — per adapter object 🫶 this is your controller's whole personality, the adapter handle you're working with.
mpi_reply — the reply payload from FW 📬 the firmware hands you back its answer in here.
mpi_request — the request payload sent to FW 📨 this is what you're sending out to the firmware.

💖 DESCRIPTION 💖

so here's the vibe: the SCSI Enclosure Processor request message makes the IOC go chat with SES devices, specifically so it can control LED status signals 💡🔴🟢

that's it. that's the whole job. LED duty. main character energy for a tiny light, no cap.

ngl it's a small function but somebody's gotta do it, and today that somebody is you, bestie 💜

⭐ RETURN ⭐

0 for success, non-zero for failure 🫡 (the classic "zero means we ate, anything else means we did not" situation)

🦋 SEE ALSO 🦋

first up, the actual source file this thing lives in, no cap:

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