What are usages of GPU in Qubes OS?

Except you use SR-IOV in the 11th and newest gen or Intel gvt in the oldest, but there was some problems with xen at least with qubes supporting that

**The problem you're addressing (if any)** GPU acceleration for HVMs, including… Windows. **Describe the solution you'd like** Enabling Intel GVT-g support (in i915) and assorted components would allow us to run HVMs with accelerated graphics. This is especially relevant to Windows HVMs. It is not clear whether this could be used to accelerate other VMs or AppVMs without compromising the security model. Because of the rendering mechanism (RGB buffer, AFAIK), it might be necessary to optimize that side of things to avoid bottlenecks between the VM and host display. **Where is the value to a user, and who might that user be?** Users with HVMs that could benefit from accelerated graphics, at near native performance. **Describe alternatives you've considered** There aren't any other alternatives for iGPUs from Intel. **Additional context** https://github.com/intel/Igvtg-xen **Relevant [documentation](https://www.qubes-os.org/doc/) you've consulted** https://github.com/intel/Igvtg-xen https://github.com/intel/gvt-linux https://wiki.archlinux.org/index.php/Intel_GVT-g **Related, [non-duplicate](https://www.qubes-os.org/doc/reporting-bugs/#new-issues-should-not-be-duplicates-of-existing-issues) issues** None found, will update in comments.

If this get fixed, for the igpu at least all VM can use it’s power

Ps… Take a closer look into this one
