_scsih_is_boot_device(9)

💖 _scsih_is_boot_device(9) 💖

okay so bestie, this is the Kernel API Manual page for _scsih_is_boot_device, and it is literally doing a search for a matching boot device. no cap. 🫶

---

✨ NAME ✨

_scsih_is_boot_device — search for matching boot device.

---

🌸 SYNOPSIS 🌸

the signature is giving “kernel C function with a whole lot of u64s”:

int _scsih_is_boot_device (u64 sas_address , u64 device_name , u64
       enclosure_logical_id , u16 slot , u8 form , Mpi2BiosPage2BootDevice_t
       *boot_device );

---

🎀 ARGUMENTS 🎀

• sas_address — sas address.
• device_name — device name specified in INDENTIFY fram. (their spelling, not mine 😭)
• enclosure_logical_id — enclosure logical id.
• slot — slot number.
• form — specifies boot device form.
• boot_device — boot device object from bios page 2.

---

🔥 RETURN 🔥

1 when there’s a match, 0 means no match. periodt. that’s the whole vibe check. 💅
