lpfc_hdw_show(9)

✨ NAME ✨

okay bestie, welcome to the lpfc_hdw_show(9) page from the Kernel API Manual 🫶 this one is simple and iconic: lpfc_hdw_show returns the jedec information about the hba. that's the vibe, no cap 💖

🌸 SYNOPSIS 🌸

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

🎀 ARGUMENTS 🎀

• dev — the class, converted to a Scsi_host structure.
• attr — the device attribute, not used. literally just vibing in the parameter list 🙈
• buf — on return, this contains the scsi vpd program type.

💫 RETURN 💫

returns the size of the formatted string. that's the whole return value, bestie ✨
