Use NULL tests of the form `if (ptr)' or `if (!ptr)'.
They do not depend on the definition of the symbol NULL.
Further, they provide the opportunity for the accidental
assignment, are clear and succinct.

Include what you want, rather than relying on a header foo.h N levels
down the include chain, to provide something that you need.

The only two remaining cases of (struct virgl_resource *) require a
closer look. Either the error checking is missing or the arguments
provided feel wrong.

The screen already has a pointer to the (base) winsys object.
With the latter of which implemented/sub-classed as either drm or sw
based one, depending on the target.

Strictly speaking virgl_hw.h should reside in the driver folder, as
it describes the hardware. Moving it allows us to nuke the following
strange dependency
winsys/vtest > driver > winsys/drm

Use the relevant GALLIUM_foo_CFLAGS which has all the requirements
(not to mention VISIBITY_CFLAGS) and keep ../ out of the include
directives.

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.
consolidate mapping and waiting code for transfers.
use u_range for dirt tracking.
handle larger shaders in protocol.
include virtgpu_drm.h in mesa for now.
add translation layer for gallium tgsi to virgl tgsi.
