Please test the kernel, which adds the affected GFX to IOMMU quirk list: https://people.canonical.com/~khfeng/gfx-no-dmar/ -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1971146 Title:

Looking at the code though, I notice that igfx=off actually filters all GFX. Maybe it's just badly named: #define IS_GFX_DEVICE(pdev) ((pdev->class >> 16) == PCI_BASE_CLASS_DISPLAY) So yeah; have a try with "intel_iommu=igfx_off" on kernel command line. -- You received this bug notification

> intel_iommu=igfx_off should be enough to resolve issues with GPUs. Maybe this design dGPU should have IOMMU off. > @Mario, would you please have some comment in this? thanks Maybe a new parameter is needed for Intel IOMMU driver to allow filtering dGPU from IOMMU too? But this type of error
