In the future, we may like to enable wc mapping of at least the GATT,
and so causing a conflict if we attempt to map the entire bar as uc-
here. Obviously we need a better fallback plan, but for the moment only
attempt to map the portion of the pci space that we use for register
access.

Rather than use the common mmio segment which will be in future
restricted to just the registers and so exclude the GTT portion on all
architectures, explicitly mmap the GTT ourselves. Repeat this mmapping
with a couple of flags until we matching the existing kernel mapping.

We share these suckers, hence the fd-local libdrn instance does not
have full control over the lifecycle of the object. Prevents the tests
from blowing up with
[drm:i915_gem_mmap_gtt] *ERROR* Attempting to mmap a purgeable buffer
and similar things.

In Valleyview the DPLL and lane control registers are accessible only
through side band fabric called DPIO. Added two tools to read and write
registers residing in this space.
v2: Moved the core read/write functions to lib/intel_dpio.c based on
Ben's feedback

With the option '-r', the testdisplay could paint a 2-D bar code(QR
bar code) on the screen. The word "pass" is hiden in the bar code
image. Further more, with this option, testdisplay will wait until a
system signal 'SIGUSR1' coming after each mode setting. This function
is for another program to control testdisplay.

When running autoreconf, it's possible to give flags to the underlying
aclocal by declaring a ACLOCAL_AMFLAGS variable in the top level
Makefile.am.
Putting ${ACLOCAL_FLAGS} there allows the user to set an environment
variable up before running autogen.sh and pull in the right directories
to look for m4 macros, say an up-to-date version of the xorg-util macros.

This will need to get modified when the ioctl expands, and so is only
here for reference/to make Daniel happy.

By adding another testcase that follows up with a gpu read. This
checks whether the kernel properly tracks the pending write and
doesn't lose it (or sync up to the wrong seqno).
For some odd reason only the cpu mmap variant blows up, the gtt one
works here. I need to look into that some more.

This wraps libdrm functionality to exec with contexts. This patch
shouldn't be applied until libdrm for contexts is updated.
