gpu display in uefi bios phase

上图相信你似曾相识吧,这是在bios阶段,我们可以看到的界面。但是,你有没有想过这样一个问题,在bios阶段,gpu的驱动并未加载,为什么我们可以看到这样的图像界面?此时,是谁在驱动gpu呢?

Introduction to qemu

1. qemu的history

QEMU was originally written by Fabrice Bellard as a very general emulator based on binary-translation. In 2008, Avi Kivity introduced the kvm module in Linux and forked the project into qemu-kvm to use the new API. The KVM support was later backported into the original QEMU, where we can find it today.
