Re: [Intel-gfx] question about i915 GPU driver in VM

[Zhang, Xiong Y] Please check whether intel_iommu is enabled on host or not. If it isn't , please add intel_iommu=on to host grub. is the dmesg from host or guest ?

Hi all, Trying to fetch the drm-intel-fixes tree today gives me this error: - fatal: Could not read from remote repository. Please make sure you have the correct access rights and the repository exists. - The same for drm-misc-fixes, drm-intel and drm-misc.

Re: [PATCH 2/2] drm/i915: Skip object locking around a no-op set-domain ioctl
Hi! > This patch causes lockups in firefox. They appear like non-fatal hangs > of the webpage contents, "fixable" with alt-tab or a background system > load. I have verified that reverting the commit 754a254427 on top of > current Linus tree fixes the problem. This is still broken in v5.2-rc3. I have also verified that the particular commit, if backported to v5.1 release, breaks firefox there too in the same way.
