lpfc_modeldesc_show(9)

💅 NAME ✨

okay so bestie, say it with me: lpfc_modeldesc_show — that's it, that's the whole function — and what it does is return the model description of the hba. literally its entire personality 🎀 (and yes, we're in the Kernel API Manual, welcome, come on in 🫶)

🌸 SYNOPSIS 🌸

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

🦋 ARGUMENTS 🦋

• dev — class converted to a Scsi_host structure. that's the main character of this parameter list tbh 👑
• attr — device attribute, not used. not me showing up to the function call just to vibe 😭💀
• buf — on return contains the scsi vpd model description. the actual payload, the moment, the reason we're all here 💖

🔥 RETURN 🔥

size of formatted string. that's the answer, no cap — it's giving "yes, and here's how many bytes I wrote" ✨

okay that's literally everyone 💀 take a breath, hydrate, then go read one 🍓

so yeah, that's the whole page bestie — sourced straight from ./drivers/scsi/lpfc, dated October 2026, filed under lpfc_modeldesc_show(9). slay, go read your hba's model description, and remember: the vibe check was passed, the docs were read, periodt 💜🧚‍♀️
