Also I just noticed that you used:

Code: Select all

uint32_t vbe_buff_size = vbe_height * vbe_width * (vbe_bpp / 8) * vbe_pitch;

to calculate the framebuffer size, but you should do it like this:

Code: Select all

uint32_t vbe_buff_size = vbe_height * vbe_pitch;

because vbe_pitch is a replacement for width * bbp / 8.

for(uint32_t i = vbe_first_page; i < vbe_first_page + vbe_page_count; i++)
		page_table[0][i] = i * PAGE_SIZE | PAGE_PRESENT | PAGE_RW | PAGE_USER;
