When looking at the pwrite/pread/wc performance, it is useful to judge
that against the performance of an ordinary CPU mmap.

Assures that signals interrupting the wait works properly. Because of
the scheduling around signals, interrupted waits will *seem* faster as
the GPU continues to work while all the CPU scheduling stuff happens.

We should get more kms tests soon, and not needing to copy-paste a
nice test pattern should be useful.
That establishes a firm depency of i-g-t on cairo over everything, but
I don't care so much about that.

The path isn't properly autodetected and it yells stupid stuff into
stderr. Which causes spurious failures.
And really, these are automated tests. If you need to look at the output,
something is wrong.

It optimized away the read loops ;-)
Also fix up the size to not be 1/4th of the one we want for tiled
buffer tests.

Unfortunately this requires slab poisoning to catch anything :(
Also add a new helper to drmtest to get the available fence count.

Now with more tiling transition tests. Changes:
- refactoring to reuse the tiling transition functions.
- add a tiled->untiled transition
- add a tiled->tiled transition with different stride
- add a check at the end to ensure that the tiling has indeed changed
on the test_bo

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
