sstfb_check_var(9)

okay bestie, welcome to sstfb_check_var(9) from the Kernel API Manual — this is the page where we check a var and keep the vibe valid. 💅✨

🌸 NAME 🌸

sstfb_check_var — optional function. Validates a var passed in. That’s the whole name, no cap. 💖

✨ SYNOPSIS ✨

okay so here’s the exact signature, bestie — literally this:

int sstfb_check_var (struct fb_var_screeninfo *var , struct fb_info
       *info );

🎀 ARGUMENTS 🎀

• var — frame buffer variable screen structure. This is the thing being validated, iykyk. 🫶
• info — frame buffer structure that represents a single frame buffer. One buffer, one info, you got this. 🌈

💅 DESCRIPTION 💅

So the whole point, bestie: this function limits stuff to the abilities of a single chip. Why? Because SLI is not supported by this driver — not a vibe this driver is on, periodt. 💀 So it keeps things within what one chip can actually handle. ✨
