Better VGA in QEMU/KVM-HV/pSeries?
« on: January 11, 2022, 08:40:17 am »
Hello,

Inspired by the post from powerpc-notebook project, where they managed to bring KVM support into Linux kernel 5.16 for the Book3e NXP T2080 CPU, I tried to actually use the QEMU with KVM-HV on my Blackbird. It works well with the pseries machine type, I managed to install FreeBSD both ppc64 and ppc64le versions, but the problem is with the graphics. QEMU says that just std and virtio -vga values are supported and both types can do only 800x600, not more.

Does anyone use KVM-HV with better resolution and if so, then how?

Thanks.

Do I get it right, that nobody here uses QEMU-KVM on Power9 with better resolution than 800x600?

I haven't played with this myself, but that does seem abnormally low. If you boot, say, Void or some other Live CD Linux distro, do you get the same limits?

I need to update my QEMU, so I can't test it just this moment.
