virgl/vtest is a swrast driver that allows the
virgl acceleration to be tested without having
a virtual machine.
The backend has a unix socket server that
this connects to.
This is run by setting
LIBGL_ALWAYS_SOFTWARE=y
GALLIUM_DRIVER=virpipe
In this mode all renderering is sent over
a socket to the remote renderer, and the
results are readback and copies to the screen
using drisw. This works well enough to develop
new features and to help debug.

virgl is the 3D acceleration backend for the
virtio-gpu shipping with qemu.
The 3D acceleration is designed around gallium
and TGSI as the virtualisation layer. The backend
renderer translates the virgl interface into
OpenGL currently.
This is the initial import of the driver to mesa.
The kernel driver portions are lined up for drm-next.
Currently this driver supports up to GL3.3 and some
misc extensions if the host driver exposes it. It is
planned to iterate the virgl API to new GL levels
as mesa host drivers gain features.
v2: fix resource tracking across flushes to avoid
->bind hack in mapping.

v2: lots of improvements
This is like identity or trace, but simpler. It doesn't wrap most states.
Run with:
GALLIUM_DDEBUG=1000 [executable]
where "executable" is the app and "1000" is in miliseconds, meaning that
the context will be considered hung if a fence fails to signal in 1000 ms.
If that happens, all shaders, context states, bound resources, draw
parameters, and driver debug information (if any) will be dumped into:
/home/$username/dd_dumps/$processname_$pid_$index.
Note that the context is flushed after every draw/clear/copy/blit operation
and then waited for to find the exact call that hangs.
You can also do:
GALLIUM_DDEBUG=always
to do the dumping after every draw/clear/copy/blit operation without
flushing and waiting.
Examples of driver states that can be dumped are:
- Hardware status registers saying which hw block is busy (hung).
- Disassembled shaders in a human-readable form.
- The last submitted command buffer in a human-readable form.

This patch and its description are inspired from Jose Fonseca
explanations and suggestions.
With this patch the following logic applies and only if __APPLE__:
When building mesa, GLhandleARB is defined as unsigned long and
at some point casted to GLuint in gl fuction implementations.
These exact points are where these errors and warnings appear.
When building an application GLhandleARB is defined as void*.
Later when calling a gl function, for example glBindAttribLocationARB,
it will be dispatched to _mesa_BindAttribLocation. So internally
void* will be treated as unsigned long which has the same size.
So the same truncation happens when casting it to GLuint.
Same when GLhandleARB appears as return value.
For mesa it will be GLuint -> unsigned long.
For an application it will be GLuint -> unsigned long -> void*.
Note that the value will be preserved when casting back to GLuint.
When GLhandleARB appears as a pointer there are also separate
entry-points, i.e. _mesa_FuncNameARB. So the same logic can
be applied.
