This is meant to test the sysfs entry for showing rc6 residency in
milliseconds. Remember, sysfs is a permanent interface.
v2: use new get_card interface to try "all" devices
check rc6p and rc6pp in addition to rc6
v3: rename rc6_residency.c to sysfs_rc6_residency.c
print better error messages
skip test if rc6 isn't enabled
v4: update to new sysfs names

By exercising the conditions whereby should either of the checks be missed
an error is detected.
Used to check that i915_error_state works. Unfortunately this
kills the gpu because wedging is permanent.
Base on a patch by Ben Widawsky.

MI_MEM_VIRTUAL actually means use global gtt now, not setting the bit
means use ppgtt. On previous gens, not setting the bits ment 'use
physical memory'. So what, the usual confusion.
Note that for some odd reasong this is broken on gen6, but only on the
bsd ring. Unexpected.

... but actually run the test with reduced memory requirements,
as the messages claims. Additional print it to stdout, stderr
seems to imply FAIL in our QA's testing rig.

Without enabling largefile support the prototype for mmap64() is broken
on Linux/x86_64 with the result being a 32-bit integer sign-extended
to fill a 64-bit pointer. Hilarity ensues.
Astonishing how dense I sometimes am ...
- increase the bo size so that we don't have any round-up to next tile
size areas (which the 2d blit go over, but the 1d pread/pwrite calls
will notice).
- correctly set tiling bits when copying back to a linear buffer.
- read back through a tiled bo to avoid messing with swizzling.

Double-include ftl and local variable shadowing. While fixing the
later I've noticed that we mix up width and height in the blt copy
function.

On SandyBridge, the BLT commands were split from the RENDER commands as
well as the BSD split inherited from Ironlake. So we need to make sure
we do exercise each ring, and in order to do so we also need to make
sure each batch takes longer to execute than it takes for us to
submit it.
v2: Exercise each ring sequentially.

We need to use _INSTRUCTION as the reloc domain because otherwise the
ppgtt pipe_control w/a for snb won't kick in and the test fails.
The storedw tests for blt and bsd are still disabled because the
corresponding patch to flag ppgtt support isn't merged upstream yet.
Without ppgtt these hang my snb here.

Replace the 8 globe force mode variables with a struct drmModeInfo variable.
Next step, we could reduce the number of globe veriables, to be convenient to call the functions.

Not testing modesetting should not be an option.
Also this hopefully prevents testdisplay build-breakage from lingering
on for days like it has in the past.
And we want to eventually test the gem/kms cross-section, i.e.
pageflips.
