💅 framebuffer_alloc(9) — Kernel API Manual 🎀

✨ NAME ✨

framebuffer_alloc — creates a new frame buffer info structure. Bestie, that’s literally the whole assignment 💖

🦋 SYNOPSIS 🦋

struct fb_info * framebuffer_alloc (size_t size , struct device *dev );

🌸 ARGUMENTS 🌸

• size — size of driver private data, can be zero.
• dev — pointer to the device for this fb, this can be NULL.

🔥 DESCRIPTION 🔥

Okay so this function creates a new frame buffer info structure. It also reserves size bytes for driver private data (info->par) 👑

info->par (if any) will be aligned to sizeof(long). Not me being picky about alignment, but yes, that’s the vibe check ✨

The new instances of struct fb_info and the driver private data are both cleared to zero. Clean slate energy fr fr 🫶

Returns the new structure, or NULL if an error occurred. Periodt 💅
