💖 sysfb_disable(9) 💖

okay bestie, this one is from the Kernel API Manual and it's literally the glow-up guide for turning off Generic System Framebuffers support ✨ don't worry, it's short and iconic.

🌸 NAME 🌸

sysfb_disable — disable the Generic System Framebuffers support

✨ SYNOPSIS ✨

void sysfb_disable (struct device *dev );

🎀 ARGUMENTS 🎀

• dev — the device to check if non-NULL 👀 that's the whole vibe.

🦋 DESCRIPTION 🦋

So this function disables the registration of system framebuffer devices that match the generic drivers which make use of the system framebuffer set up by firmware. slay 💅

It also unregisters a device if this was already registered by sysfb_init. not me being thorough 😭✨

💅 CONTEXT 💅

Heads up, bestie: the function can sleep 😴 and a disable_lock mutex is acquired to serialize against sysfb_init, that registers a system framebuffer device. iykyk 🔒
