UEFI Graphics Output Protocol in assembly

Posted 11 May 2021 - 06:38 AM

Hello! I'm trying to make a simple UEFI bootloader game and I'm struggling with using the graphics output protocol. Could you please tell me how can I draw some pixels on the screen?

Of all the places to launch a game, why in the bootloader? Seems that would have a large chance to destabilize the machine or box trying to actually boot.

I need to do this project for an university class.. I wouldn't complicate my life so much on purpose. I'm using the QEMU virtual machine to launch the bootloader.

Hello! I'm new to uefi progamming and I don't understand how to use the Graphics Output Protocol in order to draw something on the screen. Can anyone show me a basic example using this protocol? I need to do a project using this and I would really appreciate it if you could give me a hint.
