This test uses debugfs entry to set next_seqno close
to a wrapping point and then creates a load with dependant
buffer objects or with specified command to induce the wrap.
v2: Use new get_rendercpy_func as suggested by Daniel Vetter.

- mulitple write domains
- conflicting write domains
- not-yet-defined gpu domains
Also convert to subtests while at it.

Again required a bit of shuffling to avoid expensive setup and some
logic to properly handling 'skip' when only running a subtest.

Small changes to avoid expensive setup just to print out the subtest
list, and setting up the source buffers such that "early-read" works
without having run "overwrite-soure" right beforehand.

To make the testnames easier to handle in scripts, replace all
spaces with dashes.
The important part is to not print anything to stdout when enumerating
subtests, so protect the timestamp test with the right check.

This is getting in the way of piglit integration. If we want this
functionality again, we should integrate it into the IGT piglit runner
as an option.

Piglit needs a way to grab the latest list of tests to run, so add new
make targets to dump those. Note that for future extendability we'll
dump 2 different lists, one for single-testcase tests and one for
testcases with enumerable subcases. Some support code for the later
will follow in subsequent patches.

[danvet: applied some bikeshed
- changed prefix from drm_ to gem_, it's a kernel gem test
- added autohell magic to link with pthreads
- .gitignore entry

Attempt to stress test performing relocations whilst the batch is in the
CPU domain.
A freshly allocated buffer starts in the CPU domain, and the pwrite
should also be performed whilst in the CPU domain and so we should
execute the relocations within the CPU domain. If for any reason one of
those steps should land it in the GTT domain, we take the secondary
precaution of filling the mappable portion of the GATT.
In order to detect whether a relocation fails, we first fill a target
buffer with a sequence of invalid commands that would cause the GPU to
immediate hang, and then attempt to overwrite them with a legal, if
short, batchbuffer using a BLT. Then we come to execute the bo, if the
relocation fail and we either copy across all zeros or garbage, then the
GPU will hang.

This is based on tests/gem_partial_pwrite_pread which aims to detect
incoherency between CPU reads and writes to a bo whilst using it as a
source and target for GPU writes.

This will need to get modified when the ioctl expands, and so is only
here for reference/to make Daniel happy.

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.

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

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
