Linux support for Xe2 and power management will take time to mature, https://www.phoronix.com/forums/forum/linux-graphics-x-org-drivers/intel-linux/1494926-intel-xe2-lunar-lake-graphics-performance-disappoints-on-linux/ https://www.phoronix.com/forums/forum/linux-graphics-x-org-d...
Xe SR-IOV improves VM graphics performance. Intel dropped Xe1 SR-IOV graphics virtualization in the upstream i915 driver, but the OSS community has continued improvement in an LTS fork, making steady progress, https://github.com/strongtz/i915-sriov-dkms/commits/master/ https://github.com/strongtz/i915-sriov-dkms/commits/master/ & https://github.com/Upinel/PVE-Intel-vGPU?tab=readme-ov-file https://github.com/Upinel/PVE-Intel-vGPU?tab=readme-ov-file.
- iforgotpassword 2y agoAww man this is so disappointing. Intel has a pretty good track record with their Linux drivers. Too bad cost-cutting seems to have reached driver development too.
- transpute 2y agoIntel has been developing a new graphics driver stack for Xe, which will officially support SR-IOV from Xe2 onward, https://www.phoronix.com/news/Intel-New-Xe-Linux-Driver https://www.phoronix.com/news/Intel-New-Xe-Linux-Driver. It makes sense to focus Intel resources on the new hardware and driver architecture, but thanks to OSS, the existing stable driver can also be improved by community contributions.

- shadeslayer 2y agoThe issue that phoronix is facing might be due to a power management bug that is not related to the driver at all.
- teruakohatu 2y ago> Intel dropped Xe1 SR-IOV graphics virtualization in the upstream i915 driver, I missed this. Wow this is disappointing.
- reginald78 2y agoI remember being somewhat excited for Intel dGPUs since I had a real interest in a card that could do GVT-g and also might have super low idle power consumption like their iGPUs that would fit well with my VM server. We ended up with GVT-g canceled and promising of SR-IOV coming eventually and dGPUs with atrocious idle power consumption!
- shadeslayer 2y agoNot sure if we need to support SRIOV on the HW. VirtIO GPU native contexts should be good enough for most consumers. I imagine SRIOV would be useful for more advanced usecases
- transpute 2y agoSR-IOV is a rare competitive advantage of Intel GPUs over Nvidia/AMD. Why would Intel give up that advantage by directing customers to software GPU virtualization that works on AMD and Nvidia GPUs?
- shadeslayer 2y agoBecause implementing designing/manufacturing/validating SR-IOV HW is expensive. It's not something that would be useful as a differentiating feature for most consumer grade HW.
- transpute 2y agoIntel vPro CPUs with iGPUs are used by the Fortune 500 enterprise industrial base. Intel hardware is already segmented for enterprise markets and they enable/disable features for specific markets. There's lots of hardware competition for consumers, including upcoming Arm laptops from Mediatek and Nvidia. Intel can use feature-limited SKUs in both CPUs and GPUs to target specific markets with cheaper hardware and reduced functionality.
- cassepipe 2y agoSo the state of Xe support on Linux is pretty good ? Is it worth it to run Linux on Alder Lake, can it take advantage of the full power of the iGPU ?
