Hi

I tried simplekms against v5.9, and it built, and it runs, and is pretty neat.

I tried using the qxl, cirrus, and vmware card in QEMU. Weston starts on all
of them. And I did ensure that the simplekms driver was being used

That is, it works after adding GRUB_GFXPAYLOAD_LINUX=keep , to avoid having to
set a VGA option. (although not sure the equivalent in syslinux yet)
 

Thanks.
