Detailed Description

GOP (Graphics Output Protocol) driver.

This module provides a framebuffer device for the GOP framebuffer provided by the bootloader.

static void *	gop_mmap (fb_t *fb, void *addr, size_t length, size_t *offset, pml_flags_t flags)
static uint64_t	gop_init (void)

Variables
static boot_gop_t	gop
