Hi all, This is a bit a mixed pile, but I've used all the earlier patches to test the gen6+ swizzling patch and I like to send out patch series somewhat resembling the setup I've tested them in.
Patches 1-2 refactor our debugfs code a bit. Patches 3-5 implement a debugfs interface to simulate a gpu hang Patch 6 fixes the swizzle detection on i915G/i945G. This one is for stable and independent of the previous patches. Patches 7-8 add a debugfs file with information to debug swizzle issues Patch 9 implements swizzle support for snb/ivb when in dual-channel mode Benchmarking on my snb is notoriously difficult, but swizzling seems to yield a few percent in some workloads, topping out at 5% for padman. Review highly welcome.
