From your error dump, we can see the following error.
ERROR: 0x00000101
TLB page fault error (GTT entry not valid)
Cacheline containing a PD was marked as invalid
in, render ring we have
FAULT_REG: 0x000000c5
Valid
Unloaded PD Fault (PPGTT)

This is not happening in batch (checked in the render ring section).
Chris, do you think this could an issue with hw memory? Any direction to look for?
Hello Rob, Yann, This haven't been update in a long time, is this problem still valid? Rob, could you confirm if is still reproducible in latest kernels and sorry for the long delay. Thanks. Closing as no new occurrences of this problem have been reported since July 2016. If problem arise again, please file a new bug with HW and SW information and relevant logs. Thanks. |
