To pass through a GPU - you'd need an extra GPU then..?
- hedora 10mo agoAlso, the last time I checked, many GPUs explicitly detect + block this because they want you to pay for more expensive datacenter versions of the hardware. Did something change?
- taskforcegemini 10mo agowhen did you check last time? I've been using gpu passthrough for more than the last ten years with different gpus from amd to nvidia to onboard intels. last few years I went back to native windows, because some games refused to run in a vm.
- cgfjtynzdrfht 10mo agoI think you are confusing PCI passthrough with enterprise IOMMU GPU support that's nowhere to be found in consumer GPU:s.
- mhio 10mo agoA number of intel consumer CPUs support SR-IOV. The iGPU splits out to 7 "virtual functions" or pci devices to map to a VM. On latest Core Ultra's you need a 2x5 model. - https://www.intel.com/content/www/us/en/support/articles/000093216/graphics/processor-graphics.html https://www.intel.com/content/www/us/en/support/articles/000... - https://github.com/strongtz/i915-sriov-dkms https://github.com/strongtz/i915-sriov-dkms
- Nextgrid 10mo agoMy understanding is that it's trivially defeatable by configuring the hypervisor to hide itself (passthrough the real CPUID strings from the processor, ACPI/SMBIOS data/etc), and graphics drivers didn't really put any more effort into detecting beyond that. It's been years since I've been on this scene though, so my info may be out of date.
