💅 atmel_lcdfb_set_par(9) — the kernel API glow-up

okay bestie, so this page lives in the Kernel API Manual, and it's literally all about one little function that changes up your hardware state. let's get into it 🎀

✨ NAME ✨

atmel_lcdfb_set_par — alters the hardware state. that's it, that's the whole vibe. it changes the hardware state. slay 💅

🦋 SYNOPSIS 🦋

int atmel_lcdfb_set_par (struct fb_info *info );

no cap, that's the signature. int goes in, struct fb_info *info goes in, and you get an int back. iconic.

🌸 ARGUMENTS 🌸

  • info — the frame buffer structure that represents a single frame buffer 🫶 like, one struct, one framebuffer, that's the whole deal. it's giving main character energy for exactly one screen.

👑 DESCRIPTION 👑

okay so here's the tea ☕ — using the fb_var_screeninfo inside fb_info, we set the resolution of this particular framebuffer. that's the whole job. 🎯

this function alters the par AND the fb_fix_screeninfo stored in fb_info. two things, both changed, no crumbs left behind ✨

but here's the important bit, bestie, don't miss it — it does not alter var in fb_info, because we're literally using that data already 🙈 so what that means is: we depend on the data in var inside fb_info being supported by the hardware. so if your hardware doesn't back it, that's a whole situation. 💀

and that's exactly why atmel_lcdfb_check_var is always called before atmel_lcdfb_set_par — to ensure that. it's the vibe check that happens before the glow-up, iykyk. 💖

again (yes, saying it twice, because it matters ✌️): if you can't change the resolution, you don't need this function. periodt.

🔥 SEE ALSO 🔥

fr fr though — check your var data first. this function trusts it completely, and the hardware has to actually support it. no take-backs. 😭

and that's the page, bestie!! brought to you straight from ./drivers/video/fbdev, dated October 2026, filed under the very iconic name atmel_lcdfb_set_par(9). go change some hardware state, you absolute icon 👑💖✨
