🎀 NAME 🎀

okay so bestie, this is the manual page for hbm_ver_drv_show(9) in the Kernel API Manual, and its whole job is display HBM protocol version advertised by driver. That’s it, that’s the function, and honestly? iconic. 💅

✨ SYNOPSIS ✨

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

No cap, that’s the signature. Copy it exactly, don’t freestyle. 🫶

💖 ARGUMENTS 💖

• device — device pointer. Yup, a device pointer, living its best pointer life.
• attr — attribute pointer. The attribute pointer is here to vibe.
• buf — char out buffer. This is the char out buffer, the place the output hangs out. 🍓

🌸 RETURN 🌸

It returns the number of the bytes printed into buf — or an error. That’s the whole return tea. 😭
