To have a more accurate idea about any suspend/resume issues we can
perform the s/r until various phases in the s/r sequence. This way we
can isolate the given problem as being a device driver, kernel core or
BIOS related issue. Actual subtests using these new s/r phases will be
added as follow-up.
While at it also add the freeze suspend target, it's something we also
would need to test.

- Give __ prefix to internal funcstion and structs, only
igt_interruptible is used by tests.
- Move docs to igt_interruptible and adjust.
- Explain more clearly how the timeout is getting doubled each
iteration until no more interruptions happen. Also rename the
argument to give it a more meaningful name in the docs.
- Link from other functions to this one for cross-referencing.
- Rename to igt_do_interruptible to make it clearer it's a loop,
inspired by do {} while () loops.
v2: Rename instead to igt_while_interruptible and fix typos (Chris).
And add gtk-doc for igt_ioctl, too.

Convert the fixed time interruptible tests to igt_interruptible() for a

For the long running tests probing error conditions, throwing in the
signal interruptions is a good idea.

A few other tests I have updated recently to use MI_STORE_DWORD also need
the magic bit for gen4/5.

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,
s/48b/64b (Chris)
v3: rebase

If we don't close the handle from the last pass, we don't free up the
previous pass's vma immediately, changing the hole allocation.

snooped objects are not allowed to abutt uncached objects on older gen
(!llc and global GTT) or else the GPU may hang if it prefetches across a
page boundary into a different memory type (i.e. CS reading from snoop).
The kernel should be checking the alignment rules as normal.

For softpinning, we do not require either userptr or extended ppgtt, so
remove those requirements and make the tests work universally. (Certain
ABI tests require large GTT, or per-process GTT.)
In the process, make the tests more extensive - validate overlapping
handling more careful, explicitly test no-relocation support, validate
more ABI handling. And for fun, cause a kernel GPF.

i915 validates that requested offset is in canonical form, so tests need
to convert the offsets as required.
Also add test to verify non-canonical 48-bit address will be rejected.
v2: Use sign_extend64 for converting to canonical form (Tvrtko)

We get build error as we try to cast from ptr to integer
of different size on 32 bit platforms. Use unsigned long
as the cast, it will work with both 32 and 64 bit
systems.

These tests exercise the userptr ioctl to create shared buffers
between CPU and GPU. They contain error and normal usage scenarios.
They also contain a couple of stress tests which copy buffers between
CPU and GPU. These tests rely on the softpin patch in order to pin buffers
to a certain VA.
Caveat: These tests were designed to run on 64-bit system. Future work
includes adding logic to ensure these tests can run on 32-bit systems with
PPGTT support. Some tests are currently disabled for 32-bit systems for that
reason.
v2: Added cc and signed-off-by fields
v3: Fixed review comments, added helper functions. Removed userptr error
scenarios covered by existing userptr tests. Modified stress test to have
100K buffers, it now runs for ~30 mins, checks every element has been written
to correctly, and pins buffers at different VMAs.
v4: Changed name to gem_softpin
v5: More fixes. Removed the file based tests, will move them to userptr tests.
Added a function that validates appropriate PPGTT support before running tests.
Optimized stack space and memory footprint in stress test. Removed the eviction
test, will add it back after verifying proper functionality.
v6: Split basic test into userptr and bo
Fixed some coding style issues.
v7: Enhanced invalid vma pinning test to verify 32-bit PPGTT functionality.
Enabled the test for 32-bit PPGTT systems, and verify pinning fails above
32-bit addresses. Enhanced the high adress pinning test to ensure pinning
fails when EXEC_OBJECT_PINNED flag is not used. Some more cosmetic fixes to
close buffer handles. Changed userptr function to used synchronized operations.
v8: Minor change to high address pinning test as per comment.
v9: Skip the tests if softpin support is not present.
v10: Removed trailing white spaces.
v11: Keep alphabetical order in Makefile and gitignore; update error code
returned while trying to pin above the max vm size (EINVAL); test attempt
to pin above 4GB without the support 48b flag.
