IOMMU & UMA - Steam Deck Virtualisation

[kilésengati]

I recently discovered the BIOS/UEFI and couldn't help but being excited to find an "IOMMU" option.

Could this be the way for me to finally run my old StarForce games through an old Windows VM?

Just wondering if anyone has managed to pass the GPU through to a VM and if it performed well.
I'm not talking about particularly hardware hungry games. Most games sporting StarForce and other infamous DRM that works neither on modern Windows nor through WINE are old enough to barely need GPU power, but new enough to require one. And even if it shouldn't work, any results on running games in software mode on a VM?

It would be kind of weird to have IOMMU there, but no way to use it.

Cheers!

iam wondering too but may be possible through qemu/virt-manager if u switch to bazzite cuz all i know is pacman is wont work because it will remove everything not in the /home/deck directory after an update.

I did a silly thing where I left my steam deck off and unplugged for a while and it died bad, and when I charged it up for a day and turned it on the touchscreen didn’t work. I tried updating which failed, so I did a system reset and then updates worked but still no touchscreen. Tried the battery protect method but still no go. Then I turned off quick boot and quiet boot and did battery protect again, and that time the touchscreen feature did return. To be honest I think battery protect mode for long term storage should be a button in the power off menu, power off for long term storage. If the battery being above 80% is bad just have a cron job watching for the battery to get low enough THEN turn off into battery protect mode.

Surprised the bios update to fix this hasn’t happened yet.
