In context tests, we may create thousands of contexts, the noise from
each requirement passing drowning out the real information. Let's only
do the requirement test (to detect if contexts are meant to be supported
or plain broken) only on the error path.

We can move it from softpin test into lib, and since softpin support is
highly unlikely to go away in-between getparam ioctl calls, let's just
do a single call and store the value.

No functional changes.
While I'm here, let's also rename gem_uses_aliasing_ppgtt (since it's
being used to indicate if we are using ANY kind of ppgtt) and introduce
gem_uses_full_ppgtt to drop some unnecessary code from tests that were
previously calling getparam directly instead of using ioctl wrapper.
v2: drop gem_uses_full_48b_ppgtt since it's no longer used anywhere,

Some potential callers want to inject a hang into a particular context,
some want to trigger an actual ban and others may or may not want to
capture the associated error state. Expand the hang injection interface
to suit all.
v2: Disable the new kernel API, but push to provide a missing piece of
infrastucture to unbreak compilation.

If we move the igt_require() into the hang injector, this makes simple
test cases even more convenient. More complex test cases can always do
their own precursory check before settting up the test.
However, this does embed the assumption that the first context we are
called from is safe (i.e no i915.enable_hangcheck/i915.reset
interferrence).
v2: A couple of environment variables to skip hang testing or to force
hang injection even if the GPU cannot be reset.

This patch adds the testcases for verifying the new extended
gem_create ioctl. By means of this extended ioctl, memory
placement of the GEM object can be specified, i.e. either
shmem or stolen memory.
These testcases include functional tests and interface tests for
testing the gem_create ioctl call for stolen memory placement
v2: Testing pread/pwrite functionality for stolen backed objects,
added local struct for extended gem_create and gem_get_aperture,
until headers catch up (Chris)
v3: Removed get_aperture related functions, extended gem_pread
to compare speeds for user pages with and without page faults,
unexposed local_gem_create struct, changed gem_create_stolen
usage (Chris)
v4: Splitting patch to remove changes from gem_pread/gem_pwrite
to another patch (Ankit)
v5: Fixed Rebase conflicts (Ankit)
Added IGT_TEST_DESCRIPTION (Thomas Wood)
v6: Added __gem_create_stolen for user to handle error, updated
gem_create_stolen to align with gem_create function, corrected
fill_purge test (out of bound access), added testcase to validate
allocating of more than 32 bit sized buffers (Tvrtko)
v7: Removed unused variables, Corrected comments & formatting (Tvrtko)

gem_set_caching() tries to be clever and detect when the ioctl isn't
supported (thereby skipping the test). However, it forget that we may be
acting on active objects and be subject to the usual EAGAIN/EINTR
errors. We can use the drmIoctl() to wrap the raw ioctl() in order to
get the automatic restart on the interrupted syscall.

Rename the current gem_mmap__{cpu,gtt,wc}() functions into
__gem_mmap__{cpu,gtt,wc}(), and add back wrappers with the original name
that assert that the pointer is valid. Most callers will expect a valid
pointer and shouldn't have to bother with failures.
To avoid changing anything (yet), sed 's/gem_mmap__/__gem_mmap__/g'

We frequently check for device capabilities, for which we can safely
assume that there is but one on a system and so cache the first query
value and return it for all future queries. The benefit is to reduce
dmesg debug spam which helps when either bringing up a test or trying to
track down why a test fails.

When synchronising to rendering, we only want to wait for it to complete
and avoid the cache-domain side-effects of SET_DOMAIN if possible. This
has the advantage of speeding up a few tests (and thereby making the
actual test more explicit in terms of kernel operations). Of course some
tests may be reliant on the side-effects...

Just a few basic tests to make sure fb modifiers can be used and
behave sanely when mixed with the old set_tiling API.
v2:
* Review feedback from Daniel Vetter:
1. Move cap detection into the subtest so skipping works.
2. Added some gtkdoc comments.
3. Two more test cases.
4. Removed unused parts for now.
v3:
* Removed two tests which do not make sense any more after the
fb modifier rewrite.
v4:
* Moved gtkdoc comments into .c file.
* Moved all initialization into fixtures.
* Rebased for fb modifier changes.
v5:
* Added bad modifier subtest.

After setting up the copy operations, add a hanging batch. This should
mean that we complete the copy and the compare then races against the
GEM reset. Hopefully, this will catch driver bugs where the target
object is no longer accessible after the hang.
Note: hang injection is disabled until the required kernel interface is
completed. But there are useful additional tests here...
