💅 drm_fb_helper_unregister_info(9) — from the Kernel API Manual, bestie

okay so picture this: it's giving kernel graphics, it's giving fbdev era, and you've got a manual page in front of you that's genuinely the moment. welcome to the Kernel API Manual entry for drm_fb_helper_unregister_info, we're doing this together, no cap ✨

🌸 NAME 🌸

drm_fb_helper_unregister_info — unregister that fb_info framebuffer device, bye bestie 🫶

🎀 SYNOPSIS 🎀

void drm_fb_helper_unregister_info (struct drm_fb_helper *fb_helper );

literally that's it. one function, one argument, void return, she's simple, she's iconic 💅

🦋 ARGUMENTS 🦋

  • fb_helper — the driver-allocated fbdev helper. and bestie, listen to me: must not be NULL. not "probably shouldn't", must not. it's a hard requirement fr fr 🙈

✨ DESCRIPTION ✨

so what does she actually do? she's a wrapper around unregister_framebuffer, and her whole job is releasing the fb_info framebuffer device 🌈

here's the part you cannot skip (and I mean it, this is the main character energy of the whole page): you must call this before you release all the resources for fb_helper by calling drm_fb_helper_fini. before, okay? BEFORE. the way that order matters is genuinely not something you want to find out the hard way 😭🔥
