All of these 'tests' cover UMS functionality which is neither being
worked on or actively maintained.
The only cases where developers touch UMS code is to unwrap it from the
KMS codepaths and ensure that those are secure.
Anyone who feels strong about having these around can revive them, but
in all honestly do consider _seriously_ what you're doing ;-)

Relative to the original version, here one can provide a flags bitmask.
Currently only DRM_DEVICE_IGNORE_PCI_REVISION is supported.
Implementation detail:
If it's set, we will only parse the separate sysfs files and we won't
touch the config one. The latter awakes the device (causing delays)
which is the core reason why this API was introduced.
v2:
- Initialize revision to 0xff if it's unread.
- Change DRM_DEVICE_IGNORE_PCI_REVISION to DRM_DEVICE_GET_PCI_REVISION
- Add explicit note that drmGetDevice[s]2 does not retrieve the
revision by default.
v3:
- Correctly fold drmParsePciDeviceInfo() hunk in this patch.

Up-to recently (patch should land in 4.10) the kernel did not expose the
PCI device revision field as a separate sysfs file.
Thus one needed too parse the config file to retrieve it. This in
itself wakes up the device, which in some cases can be quite slow.
To avoid that, just check for the separate files and fall-back to the
original if kernel is not new enough.
v3: rework alongside drmGetDevice[s]2

The original version considered only card devices, while this will pick
the device/node name regardless - card, control, renderD, other...
Current implementation is "linux" specific, in such that it relies on
sysfs/uevent file. At the same time this gives us the flexibility to
support any nodes even future ones, as long as they're within DRM_MAJOR.

Exposing the u32 context ID makes it possible to define new drm kernel
interfaces based on the same IDs that e.g. execbuf uses to identify a
gem context, that aren't themselves abstracted by libdrm but need to be
used by libdrm/drm_intel_context based clients such as (parts of) i-g-t
or Mesa.
For example this can be used to configure an i915-perf stream to collect
metrics for a specific context.

As well as allowing a hexadecimal PCI ID number, the
INTEL_DEVID_OVERRIDE environment variable can now contain one of a few
short codenames. The codenames are stored in a small table to map them
to a corresponding PCI ID. This makes it easier to use without having
to look up the PCI IDs manually.
The PCI IDs used are the same as those chosen for the -p option of
run.c in shader-db but SKL has been added as well.

Update kernel interface with new I915_GETPARAM ioctl entries for
pooled EU and min no. of eus in a pool. Add a wrapping function
for each parameter. Userspace drivers need these values when decide
the thread count. This kernel enabled pooled eu by default for BXT
and for fused down 2x6 parts it is advised to turn it off.
But there is another HW issue in these parts (fused
down 2x6 parts) before C0 that requires Pooled EU to be enabled as a
workaround. In this case the pool configuration changes depending upon
which subslice is disabled and the no. of eus in a pool is different,
So userspace need to know min no. of eus in a pool.
