mpi3mr_trans..._smp_handler(9)

💅 mpi3mr_transport_smp_handler(9) ✨

okay so bestie, welcome to the Kernel API Manual 🎀 — yes we're in kernel-land, yes it's giving "I read C for fun," and honestly? slay. this one's a tiny little function with a big job and a huge friend group, so buckle up 🦋

---

✨ NAME ✨

mpi3mr_transport_smp_handler — the handler for smp passthru 💫

like, it handles the SMP passthru. that's the whole vibe. short king. 👑

---

🩷 SYNOPSIS 🩷

void mpi3mr_transport_smp_handler (struct bsg_job *job , struct
Scsi_Host *shost , struct sas_rphy *rphy );

returns void bc it doesn't owe you a status code, periodt 💅

---

🌸 ARGUMENTS 🌸

• job — the BSG job reference 🫶 this is the actual work order being handed over, no cap
• shost — the SCSI host object reference 🌈 your SCSI host, right there, referenced
• rphy — the SAS transport rphy object pointing the expander 🧚 this is the one that's pointing at the expander

---

💖 DESCRIPTION 💖

so here's the tea ☕ — this bad boy is used primarily by smp utils to send SMP commands to the expanders attached to the controller. that's it. that's the function. it's the little messenger fairy 🧚‍♀️ carrying your SMP commands over to the expanders, lowkey iconic, highkey essential.

not me being obsessed with a passthru handler 😭 but here we are.
