Any update on that one?
No, reverting that will cause just another bug elsewhere. I need to work out how the gpu is not being flushed with a non-pipelined fence change.
There's that whole "return -EINVAL for I915_PARAM_HAS_RELAXED_FENCING" patch thing?
As it turns out this is a bug in the userspace components of the stack for gen2 hardware, with lax kernel side enforcement. Daniel has a fix for both.
Chris, could you point us at the patch? I ask because Daniel left a comment in bug discussion that we should ignore some patch from him, and there was no mention of anything else.
I'll gladly test a better fix.
