My experience with these patches is that they make it less likely that the hang is reported to the userspace in a timely fashion (filling the ring full leads to lots of lost rendering) and worse make it much more likely that i915_gem_fault() hits an EIO and goes bang. That is unacceptable and trivial to hit with these patches. I have not yet reproduced that issue using the same broken renderer without these patches.
I do think the patches are a step in the right direction, but with the change in userspace behaviour it has to be a NAK for the time being. -Chris -- Chris Wilson, Intel Open Source Technology Centre _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/intel-gfx
