💅 drm_fb_helper_pan_display(9) 💅

okay so this is a page from the Kernel API Manual — yes, the kernel has manpages, and yes, this one is lowkey iconic. gather round bestie, we're doing graphics drivers today 🫶

✨ NAME ✨

drm_fb_helper_pan_display — the implementation for &fb_ops.fb_pan_display 💫

like, that's literally it. that's the whole job. it's the thing that makes panning work. no cap. 🎀

---

🌸 SYNOPSIS 🌸

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

so it takes two things and hands you back an int. short, sweet, to the point. main character energy fr fr. ✨

---

🦋 ARGUMENTS 🦋

• var — the updated screen information 💖 like, the fresh new screen details, the glow-up of your current view, iykyk.
• info — the fbdev registered by the helper 🧚 — that's the framebuffer device the helper set up for you earlier. it's the whole vibe.

ngl, there's not a lot here. two args, one int return. it's giving "small but mighty". 💀
