drm/i915: Remove bitmap tracking for used-ptes
*** This bug has been marked as a duplicate of bug 99295 ***
Since dd19674bacba227ae5d3ce680cbc5668198894dc is for 4.12-rc, I have back-ported the fix to version 4.11 of the kernel.
Built Fedora RPMs for it: https://copr.fedorainfracloud.org/coprs/alonid/kernel-4.11-drmfix/, and currently running it on my laptop.
Can we review and get this into 'drm-intel-fixes'?
Thanks a lot ! I'm testing your custom kernel with drm fix right now, I'll report how it goes.
Seems to run fine until now, will test for a few more days to be sure.
I got an i915 related error though in the logs:
[drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe A FIFO underrun
Not sure if due to this patch or not.
One full day without any freeze, haven't happen in a long time, really happy with the fix so far ! Thanks a lot !
Good to hear!
For me the problem is less frequent, so I was not sure yet if it is effective. I have some issues resuming from suspend but I am not sure they are related.

New stack trace after fix
Worked well for a few days, but I had a new freeze this morning.
So I agree with you, the fix only seems to make it much less frequent.
See attached stacktrace.
