Intel graphics drm errors only with iommu enabled

Hi all,

I have been using arch for a few months now I wanted to switch from dual booting to pure arch. In preparation for GPU pass through I have had some major issue with using the onboard graphics of my intel i7-3770. I first tried to boot with no intel drivers as it is recommended on the wiki to use the modesetting drivers but it fails to boot into the graphical session, looking at the log there we not any obvious errors but no matter what I did I could not get it to run, I can post the log if required. By installing the xf86-video-intel package I managed to boot succesfully into KDE, but the display connected to onboard graphics did not show up in xrandr. After some research I found these commands and these initialized the display how I wanted to.

xrandr --setprovideroutputsource 1 0 # enables intel outputs to be shown
xrandr --output HDMI1 --auto
xrandr --output HDMI1 --right-of DisplayPort-3

I thought I had everything ready for GPU pass through, but upon enabling IOMMU with the intel_iommu=on argument I get the following error on boot:

12.057198] [drm:intel_set_cpu_fifo_underrun_reporting [i915]] *ERROR* uncleared fifo underrun on pipe A
[   12.057310] [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe A FIFO underrun

[   12.057494] [drm:intel_pch_fifo_underrun_irq_handler [i915]] *ERROR* PCH transcoder A FIFO underrun

I have looked through various threads with this error but none seem to correspond with the issue I am having.

My kernel args:

Now when I tried to use those xrandr commands the system freezes. I have tried with the current kernel: 4.9.11-1-ARCH, linux-vfio-lts and linux-vfio. All of which contain the same issue.

Any ideas? Any more information required just ask!

Re: Intel graphics drm errors only with iommu enabled

You could try with 'intel_iommu=on,igfx_off'. I can also see this problem and all I can say is it got harder to trigger with either kernel 4.8 or 4.9 (don't recall exactly). See this long bug report upstream[1] from which came some bug fixes and improvements. I know it's not the same generation cpu/gpu as yours but the reported problem runs along the same lines.

I have the iommu on in my machine (i7-6500U) not because I'm doing any passthrough but because I've read somewhere that it should increase security and resilience against driver/hardware missbehaving and corrupting/accessing memory it shouldn't. If I use 'intel_iommu=on,igfx_off' I can't trigger the problem, if I use only 'intel_iommu=on' I can manage to trigger the problem, although I haven't found any sure fire way to trigger it, all I know is if I use kvm I manage to trigger the problem after a while.

Currently I don't have enough time to pursue this upstream with a bug report(1) but if you have the time and motivation you should submit a bug upstream.

(1) This means one has to compile the kernel with any proposed patches and report the results. You should be committed about solving the problem and see it through, reporting the problem and later abandoning it after a few iterations is not nice.
