Tegra K1 and later use a GPU that can be driven by the Nouveau driver.
But the GPU is a pure render node and has no display engine, hence the
scanout needs to happen on the Tegra display hardware. The GPU and the
display engine each have a separate DRM device node exposed by the
kernel.
To make the setup appear as a single device, this driver instantiates
a Nouveau screen with each instance of a Tegra screen and forwards GPU
requests to the Nouveau screen. For purposes of scanout it will import
buffers created on the GPU into the display driver. Handles that
userspace requests are those of the display driver so that they can be
used to create framebuffers.
This has been tested with some GBM test programs, as well as kmscube and
weston. All of those run without modifications, but I'm sure there is a
lot that can be improved.
Some fixes contributed by Hector Martin <marcan@marcan.st>.

Changes in v3:
- properly unwrap resources in ->resource_copy_region()
- support vertex buffers passed by user pointer
- allocate custom stream and const uploader
- silence error message on pre-Tegra124
- support X without explicit PRIME
Changes in v4:

Part 1 of 2 (part 1 is autoconf changes, part 2 is C++ changes)
When only a single SWR architecture is being used, this allows that
architecture to be builtin rather than as a separate libswrARCH.so that
gets loaded via dlopen. Since there are now several different code
paths for each detected CPU architecture, the log output is also
adjusted to convey where the backend is getting loaded from.
This allows SWR to be used for static mesa builds which are still
important for large HPC environments where shared libraries can impose
unacceptable application startup times as hundreds of thousands of copies
of the libs are loaded from a shared parallel filesystem.
Based on an initial implementation by Tim Rowley.

Currently the versions are set in the header, and then sed is used to
extract them, so that autotools can use them elsewhere.
This is odd. Autotools is perfectly capable of configuring the header
with the versions, and then they don't need to be extracted from the
the header. This is cleaner and more obvious.

While modern pthread mutexes are very fast, they still incur a call to an
external DSO and overhead of the generality and features of pthread mutexes.
Most mutexes in mesa only needs lock/unlock, and the idea here is that we can
inline the atomic operation and make the fast case just two intructions.
Mutexes are subtle and finicky to implement, so we carefully copy the
implementation from Ulrich Dreppers well-written and well-reviewed paper:
"Futexes Are Tricky"
http://www.akkadia.org/drepper/futex.pdf
We implement "mutex3", which gives us a mutex that has no syscalls on
uncontended lock or unlock. Further, the uncontended case boils down to a
cmpxchg and an untaken branch and the uncontended unlock is just a locked decr
and an untaken branch. We use __builtin_expect() to indicate that contention
is unlikely so that gcc will put the contention code out of the main code
flow.
A fast mutex only supports lock/unlock, can't be recursive or used with
condition variables. We keep the pthread mutex implementation around as
for the few places where we use condition variables or recursive locking.
For platforms or compilers where futex and atomics aren't available,
simple_mtx_t falls back to the pthread mutex.
The pthread mutex lock/unlock overhead shows up on benchmarks for CPU bound
applications. Most CPU bound cases are helped and some of our internal
bind_buffer_object heavy benchmarks gain up to 10%.

So far clover based its test for compiler support on the version of gcc,
while in reality support for c++11 is required. This patch replaces the
version check by the check unified for all modules that require c++11.
Reviewed-by: Emil Velikov <emil.velikov@collabora.com>
Add a check that tests whether the c++ compiler supports c++11, either
by default, by adding the compiler flag -std=c++11, or by adding a
compiler flag that the user has specified via the environment variable
CXX11_CXXFLAGS.
The test only does a very shallow check of c++11 support, i.e. it tests
whether the define __cplusplus >= 201103L to confirm language support
by the compiler, and it checks whether the header <tuple> is available
to test the availability of the c++11 standard library.
A make file conditional HAVE_STD_CXX11 is provided that is used in this
patch to enable the test in st/mesa if C++11 support is available.

Earlier versions need different quirks, but as of LLVM 3.9 llvm-config

The output of which seems to be reliable - looking at LLVM 3.9, 4.0 and
5.0.
Note that there are earlier code will be used for pre LLVM 3.9 and is
unchanged.
This effectively fixes LLVM static linking, while providing a clearer
and more robust solution for future versions.
Mildly interesting side notes:
- build-mode (introduced with 3.8) was buggy with 3.8
It shows "static" when build with -DLLVM_LINK_LLVM_DYLIB=ON, yet it was
consistent with --libs. The latter shows the static libraries.
- libnames and libfiles are broken with LVM 3.9

There is a handful of dead code that we could remove, which will be

Note: this drops the LLVM 3.6 build from the Travis build. LLVM 3.9 (and
