[Intel-gfx] [PATCH 0/9] gpu hang and swizzle patches

[Daniel Vetter]

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.

Cheers, Daniel
