Re: [Xen-users] Nvidia GeForce Passthrough Without Modifying to Quadro
Hi Gordan, Jacek,

Perhaps, but in reality primary passthrough / vga=none
isn't really all that useful. It's not like SeaBIOS has
a configuration menu of any sort to view/use.
On Windows domU all you miss is the POST and splash screen.
On Linux you only miss the POST and the initial kernel boot
log until the GPU frame buffer driver loads.
It might be handy for things like seeing the grub menu
on the domU's physical monitor, but that's about it.
What is the actual use-case for primary passthrough?
Video output during boot of an operating system is a very critical piece of feedback for the user. ÂGetting stuck in Windows startup repair is maddening, too ;)
It's tempting to think of everything prior to kernel initialization as unimportant, but some hardware is really picky, and users even more so. ÂThe closer that Xen comes to completelyÂshimming every type of firmware there is with maximum compatibility, the more fun virtualization is going to get :)
