With the new engine query method engines are reachable through
an index and context they are combined with.
The 'gem_has_ring()' becomes 'gem_context_has_engine()' that
requires the index that the engine is mapped within the driver.
The function has been moved from lib/ioctl_wappers to
lib/i915/gem_context where it is more appropriate.
The previous 'gem_has_ring()' function becomes a wrapper to the
new 'gem_context_has_engine()'.

One significant usecase for intel_reg/etc. is to be able to examine
the hardware state *before* loading the driver. If the tool forces
the driver to load we've totally lost that capability.

vmwgfx and amdgpu doesn't support fb modifiers, yet kms_addfb() requires
modifier support. Since many tests don't need this to run, the
requirement can be made less broad.
Therefore, tighten the requirement to cases where modifiers are actually
needed.
v2:
* In create_fb() calls to kms_addfb(), remove the modifier flag iff the
driver doesn't support modifiers and the modifer is 0
* Don't modify the flag in kms_addfb().

Pollable spin batch exports a spin->running pointer which can be checked
by dereferencing it to see if the spinner is actually executing on the
GPU.
This is useful for tests which want to make sure they do not proceed with
their next step whilst the spinner is potentially only being processed by
the driver and not actually executing.
Pollable spinner can be created with igt_spin_batch_new_poll or
__igt_spin_batch_new_poll, after which igt_spin_busywait_until_running can
be used to busy wait until it is executing.

clean slate to work with, and avoids left-over state from previous tests
impacting on the next. In particular, somes tests may be setting up long

checking on behalf of the caller (to avoid having lots of repetitious

for the test, we also expose a double underscore version. Fix up
__gem_create() to follow this pattern and report the negative error code

igt_require_gem() checks whether we can use the i915 fd for submitting
requests by detecting a wedged driver. It was intended to be used just
after opening DRIVER_INTEL for a gem test to provide an early skip if
the device was unusable. However, it is also used at the start of
library functions like igt_spin_batch_new() which may be called after
the test has setup some state, and importantly submitted some batches.
igt_require_gem() has the risk of then waiting on those batches, unless
we tell it to use a clean fd.

The MOCS registers were added in Gen9 and define the caching policy.
The registers are split into two sets. The first set controls the
EDRAM policy and have a set for each engine, the second set controls
the L3 policy. The two sets use the same index.
The RCS registers and the L3CC registers are stored in the RCS context.
The test checks that the registers are correct by checking the values by
directly reading them via MMIO, then again it tests them by reading them
from within a batch buffer. RCS engine is tested last as it programs the
registers via a batch buffer and this will invalidate the test for
workloads that don't use the render ring or don't run a render batch
