s1d13xxxfb_set_par(9)

💅 NAME 💅

okay so bestie, welcome to s1d13xxxfb_set_par(9) from the Kernel API Manual ✨ this one's whole personality is s1d13xxxfb_set_par — alters the hardware state. periodt. 💅

🌸 SYNOPSIS 🌸

int s1d13xxxfb_set_par (struct fb_info *info );

🎀 ARGUMENTS 🎀

• info — the frame buffer structure 🫶 she's the main character here, ngl.

🦋 DESCRIPTION 🦋

So, using the fb_var_screeninfo in fb_info, we set the depth of the framebuffer. lowkey iconic. ✨

This function alters the par AND the fb_fix_screeninfo stored in fb_info. It doesn't not alter var in fb_info since we are using that data — and yes, bestie, that's the original's exact "doesn't not" double-negative, I'm not fixing it 😭. This means we depend on the data in var inside fb_info to be supported by the hardware. xxxfb_check_var is always called before xxxfb_set_par to ensure this. fr fr.

XXX TODO: write proper s1d13xxxfb_check_var, without which that function is quite useless. 💀 not the TODO calling itself useless... 🙈
