Log Message:
Revert "i915: Reduce diff in fault routine."
Evidently this had more side effects than I thought:
warning: ../../../../external/bsd/drm2/dist/drm/i915/intel_uncore.c:1197:
Unclaimed read from register 0x61204
...
{drm:netbsd:wait_panel_status+0x74} *ERROR* PPS state mismatch
...
warning: ../../../../external/bsd/drm2/dist/drm/i915/display/intel_dp.c:1175:
eDP powered off while attempting aux channel communication.
...
warning: ../../../../external/bsd/drm2/dist/drm/i915/display/intel_dp.c:5616:
Missing case (((&(dev_priv)->__info)->gen) == 9)
So let's roll it back until I have a better understanding of what
changed.
Between making the change and writing the commit message, I forgot
that the change affected the errno values returned by the fault
routine, which may affect how uvm handles the fault failure --
whether to retry, wait for memory and retry, or fail, or what.
Perhaps that explains the issue.
