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 v2:
- duplicate file descriptor in winsys to avoid potential issues
- require nouveau when building the tegra driver
- check for nouveau driver name on render node
- remove unneeded dependency on libdrm_tegra
- remove zombie references to libudev
- add missing headers to C_SOURCES variable
- drop unneeded tegra/ prefix for includes
- open device files with O_CLOEXEC
- update copyrights
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:
- ship Meson build files in distribution tarball
- drop duplicate driver_tegra dependency

It should be possible to build EGL without GLX, but the meson build
currently doesn't allow that because it too tightly couples glx and dri.
This patch eases dri and glx apart, so that EGL without GLX can be
built.

those building a driver that doesn't support the OMX state tracker to

The disk cache implementation uses 64-bit atomic operations. For some
architectures, such as 32-bit ARM, GCC will not be able to translate
these operations into atomic, lock-free instructions and will instead
rely on the external atomics library to provide these operations.
Check at configuration time whether or not linking against libatomic
is necessary and if so, create a dependency that can be used while
linking the mesautil library.
This is the meson equivalent of 2ef7f23820 ("configure: check if
-latomic is needed for __atomic_*").
For some background information on this, see:
https://gcc.gnu.org/wiki/Atomic/GCCMM

- clarify meaning of lock-free in commit message

3 digits versions in LLVM only started from 3.4.1 on.
Hence, even if you can perfectly build with an old LLVM (< 3.4.1) in
the system while not needing LLVM at all (auto), when passing through
the LLVM version detection code, meson will fail when accessing
"_llvm_version[2]" due to:
"Index 2 out of bounds of array of size 2."

Currently there is not a separate option for setting the search path of

`dri-search-path`, which will default to the value of
