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)

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'
over the entire codebase.

Get rid of the gem_mmap() alias of gem_mmap__gtt(). I don't see any
point in having it.

On gen8, we should check that the full 64bit relocation value is
correct, and we should be sure to poison the relocation offset between
runs.

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.

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.

Just spotted while driving around. gtkdoc needs the full parameter
list otherwise it doesn't recognize it as a function. So add them.

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...

Also some tiny polish to function interface:
- @caching in gem_set_tiling should be uint32_t to match the ioctl
struct.
- s/size/length/ for gem_write/read.
- move gem_get_num_rings to the other ring feature helpers.
v2: Also demote gem_require_ring from static inline and move it, too.
v3: Also move gem_handle_to_libdrm_bo.

I want to group the ioctl wrappers and related functions into their
own documentation section.
Apparently gtkdoc refuses to obey this wish without a corespdonding
header. So appease it. Also gtkdoc seems to struggle with rebuilding a
bit ...
