💅 mpt3sas_config_get_number_hba_phys — Kernel API Manual, bestie edition ✨

okay so picture this: you're deep in the kernel, specifically the mpt3sas corner of it, and you just need to know how many phys your host has. That's literally the whole vibe of this page. It's from the Kernel API Manual, and it is, no cap, so straightforward. 🦋

---

✨ NAME ✨

mpt3sas_config_get_number_hba_phys — obtain number of phys on the host 💫

like yes, that's it, that's the function. she's here to count phys. periodt.

---

🌸 SYNOPSIS 🌸

int mpt3sas_config_get_number_hba_phys (struct MPT3SAS_ADAPTER *ioc , u8
*num_phys );

copy it exactly, bestie, don't get creative with the signature 🙈

---

🎀 ARGUMENTS 🎀

• ioc — the per adapter object, i.e. the little passport for your adapter. main character energy, honestly.
• num_phys — a pointer that gets returned with the number of phys. so you pass in the address and it hands you back the count 💖

---

🧚 CONTEXT 🧚

sleep.

yep. that's the whole section. it sleeps. sleep. as in, you can sleep during this one — it's not one of those "must not sleep" panic situations, so breathe 😮‍💨✨

---

🔥 RETURN 🔥

• 0 for success 🎉
• non-zero for failure 💀

that's the whole deal. 0 = slay, anything else = not slay.

💜 that's the whole page, bestie. short, sweet, extremely functional. now go count those phys. 🫶

this little love letter lives in ./drivers/scsi/mpt3sas, dated October 2026, and it's signed off on the mpt3sas_conf...ber_hba_phys(9) page itself 💅✨ (yes the title is truncated with ..., no I will not be fixing it, that's what the original says 🎀)
