fbtft_framebuffer_alloc(9) 💅

Okay bestie, welcome to the Kernel API Manual corner — this is the entry for fbtft_framebuffer_alloc, aka the function that creates a new frame buffer info structure. Main character energy for your display stack, fr fr.

✨ NAME ✨

fbtft_framebuffer_alloc — creates a new frame buffer info structure

✨ SYNOPSIS ✨

struct fb_info * fbtft_framebuffer_alloc (struct fbtft_display *display
, struct device *dev , struct fbtft_platform_data *pdata );

🌸 ARGUMENTS 🌸

• display — pointer to the structure describing the display
• dev — pointer to the device for this fb; this can be NULL
• pdata — platform data for the display in use

💖 DESCRIPTION 💖

Creates a new frame buffer info structure. Slay.

No cap, it also creates and populates these following structures:

• info->fbdefio
• info->pseudo_palette
• par->fbtftops
• par->txbuf

Returns the new structure, or NULL if an error occurred. So if you get NULL, that's the error vibe check — not a mysterious side quest. 😭
