Workarounds for BDW are applied using LRIs during render ring initialization.
Only those WA registers that are part of register state are initialized
in this fn, remaining are still in its current place init_clock_gating() which
are not affected by a gpu reset. I can send another patch where they
The workarounds that are applied are exported to a debugfs file;
this is used to verify their state after the test case (reset or
suspend/resume etc). This patch is only required to support i-g-t.

For BDW workarounds are currently initialized in init_clock_gating() but
they are lost during reset, suspend/resume etc; this patch moves the WAs
that are part of register state context to render ring init fn otherwise
default context ends up with incorrect values as they don't get initialized
Some of the workarounds are lost followed by a gpu reset, suspend/resume;
this patch adds a test which compares register state before and after
the test scenario.
This test currently verifies only bdw workarounds.

Hi all,
New -testing cycle with cool stuff:
- basic code for execlist, which is the fancy new cmd submission on gen8. Still
disabled by default (Ben, Oscar Mateo, Thomas Daniel et al)
- remove the useless usage of console_lock for I915_FBDEV=n (Chris)
- clean up relations between ctx and ppgtt
