In some environments, we don't really want to loop 100000 times or
allocate 152352621 buffers because it makes the tests too long to run.
This adds a way to specify "quick" values to reduce the time taken by
certain tests.

Everywhere else we search for a match based on an Intel display
device, so if the quick check of the fixed slot fails, fallback to
walking the PCI bus looking for a match.

To make these helpers as least invasive as possible simply initialize
the options with a getopt parser and let the control flow be steered
with a simple helper which gets the subtest name as an argument.
The only tricky part for using it is that the subtest check helper
doubles up as the conduit to enumerate tests (and in that mode
prevents any test from being run). It is therefore important that
nothing gets printed to stdout outside of these checks.

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.

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.

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

When looking at the pwrite/pread/wc performance, it is useful to judge
that against the performance of an ordinary CPU mmap.

Using BEGIN_BATCH can lead to a nice inf recursion through require_space
-> flush_batch -> BEGIN_BATCH.
Also fix things up to always require BATCH_RESERVED. We need 2 dwords
for the gen5 workaround and 2 dwords for MI_BB_END.
We should get more kms tests soon, and not needing to copy-paste a
nice test pattern should be useful.
That establishes a firm depency of i-g-t on cairo over everything, but
I don't care so much about that.

Although the address space for GTT mappings may only be 32-bits, we need
to use the explicit 64-bit mmap interface so that on a 32-bit platform
the offset we pass is not truncated to 31-bits.
Fixes gem_mmap_offset_exhaustion on 32-bit platforms.

This is meant to test the sysfs entry for showing rc6 residency in
milliseconds. Remember, sysfs is a permanent interface.
v2: use new get_card interface to try "all" devices
check rc6p and rc6pp in addition to rc6
v3: rename rc6_residency.c to sysfs_rc6_residency.c
print better error messages
skip test if rc6 isn't enabled
v4: update to new sysfs names

MI_MEM_VIRTUAL actually means use global gtt now, not setting the bit
means use ppgtt. On previous gens, not setting the bits ment 'use
physical memory'. So what, the usual confusion.
Note that for some odd reasong this is broken on gen6, but only on the
bsd ring. Unexpected.
