lpfc_option_...version_show(9)

📦 version 7.3.1, in nixpkgs unstable

okay so real talk — this one's lpfc_option_rom_version_show(9), and it lives in the Kernel API Manual (yes bestie, that manual 💅). She's a tiny little sysfs show function and honestly? she ate. let's get into it 🫶

✨ NAME ✨

lpfc_option_rom_version_show — Return the adapter ROM FCode version 🎀

that's it. that's the whole job. she reads the ROM + FCode version strings and hands them over. iconic, no notes 💖

🌸 SYNOPSIS 🌸

ssize_t lpfc_option_rom_version_show (struct device *dev , struct
device_attribute *attr , char *buf );

okay so the return type is ssize_t (a size, bestie, remember that, it comes back later 👀), and she takes three things. literally only three. we love a low-maintenance queen ✨

🦋 ARGUMENTS 🦋

  • dev — class converted to a Scsi_host structure. so like, it shows up looking like a struct device * but she gets converted into a Scsi_host on the inside. glow-up moment 💫
  • attr — the device attribute. not used. ma'am is simply here for the vibes, she contributes nothing and we respect her for it 🙈
  • buf — on return, this is where the ROM and FCode ascii strings end up. so the actual tea gets poured in here 🍓

🔥 RETURN 🔥

size of formatted string. that's the ssize_t from earlier making her grand entrance, no cap 👑

💜 SEE ALSO 💜

okay this list is long long, like a group chat with everyone in it, but every single one of them is getting named because we don't do exclusion here 💅
