drm_fb_helper_gem_is_fb(9)

📦 version 7.3.1, in nixpkgs unstable

💅 drm_fb_helper_gem_is_fb 💅

okay so bestie, welcome to the drm_fb_helper_gem_is_fb(9) page — that's the Kernel API Manual, and this is literally the whole vibe check for one tiny question: does fbdev emulation use this GEM object as its framebuffer? Let's get into it 🫶

✨ NAME ✨

drm_fb_helper_gem_is_fb — Tests if GEM object is framebuffer 👑

🦋 SYNOPSIS 🦋

bool drm_fb_helper_gem_is_fb (const struct drm_fb_helper *fb_helper ,
const struct drm_gem_object *obj );

🎀 ARGUMENTS 🎀

  • fb_helper — your fb_helper instance, and bestie… it can be NULL. No pressure. 🙈
  • obj — the GEM object you're testing, and yeah, this can be NULL too. Very forgiving energy. ✨

🔥 DESCRIPTION 🔥

Call drm_fb_helper_gem_is_fb to test if a DRM device's fbdev emulation uses the specified GEM object for its framebuffer. That's it, that's the whole job — it's giving very focused main character energy. 💅

Heads up though: the result is always false if either pointer is NULL. Like, zero drama, zero surprises — NULL in, false out, periodt. 💀

🌈 RETURN 🌈

True if fbdev emulation uses the provided GEM object, or false otherwise. Simple as that, no cap. ⭐
