i91u_biosparam(9)

💖 i91u_biosparam 💖

okay bestie, welcome to the i91u_biosparam(9) page from the Kernel API Manual ✨ this one's a tiny little function but it's lowkey doing important work, ngl.

---

🌸 NAME 🌸

i91u_biosparam — return the "logical geometry

(yes, the quote is literally open-ended like that in the original, and no, we do not close it. we respect the lore 🫶)

---

✨ SYNOPSIS ✨

int i91u_biosparam (struct scsi_device *sdev , struct gendisk *unused ,
sector_t capacity , int *info_array );

---

🎀 ARGUMENTS 🎀

• sdev — the SCSI device, our main character 💅
• unused — the matching gendisk. it's literally named unused, so like… do not expect it to do anything, it's just here for the vibes 🙈
• capacity — sector size of the drive, the numbers part of the story 🔢
• info_array — the return space where the BIOS geometry gets dropped off 🎁

---

🦋 DESCRIPTION 🦋

so what does it do? it maps the device geometry in a way that's compatible with the host controller BIOS behaviour. that's the whole assignment, and it ate 🔥

💀 FIXME: limited to 2^32 sector devices. that's a real cap, bestie — don't come crying to me when you hit it, it's literally written in the source.
