Currently, we always try to create an OpenGL 3.1 context. Some
dEQP tests require an OpenGL 3.2 context (specifically, ones
that use glGetInteger64v). Let's try to create the highest
version context we can, and iterate to lower versions, i.e:
https://developer.android.com/guide/topics/graphics/opengl.html#version-check
The return code for (*create_gl_context) is a little unclear.
This patch assumes NULL is returned on failure. This should work
for GLX and EGL.
GLX:
"On failure glXCreateContextAttribsARB returns NULL and generates
an X error with extended error information"
https://www.khronos.org/registry/OpenGL/extensions/ARB/GLX_ARB_create_context.txt
EGL:
"#define EGL_NO_CONTEXT ((EGLContext)0)"
https://www.khronos.org/registry/EGL/api/1.1/EGL/egl.h
The semantics of rcbs->create_gl_context may be different, though.

These two formats are required by DRI in the guest and as such
Wayland, X11, GBM or any API built on top if DRI. The format
GL_BGRA_EXT is not supported on Desktop OpenGL.

These are needed for ARB_draw_indirect and GL4.0
This enables support and turns in the cap when
support is present.
This also enhances the draw packets to cover
future features, it doesn't enable or show these
yet, since other work is required in the shaders.

In vrend clear dispatch function, the 'buffers' is read from
guest. A malicious guest can specify a bad 'buffers' to make
a the function call util_format_is_pure_uint() even the
'ctx->sub->surf[i]' is NULL. This can cause a NULL pointer deref.
Make a sanity check to avoid this.

That way an value if (type > PIPE_SHADER_GEOMETRY) guard will actually
work for all values.

Instead of polling the fences regularly, have a thread
that blocks for a single fence using a separate shared
context, then uses eventfd to wake up the main thread
when something happens.
Inside the guest, glmark2 typicially runs twice as fast with the thread
sync. Although in general, the performances seems to be about +30%. The
benefits is mostly for CPU-bounds tasks (when main the thread hits 100%)
A naive perf stat of the vtest renderer with glmark2 "build" test with a
fixed number of frames (500) results in the following stats data:
(do not value timing related informations, since the renderer is ran and
stopped manually)

the protocol failed to handle larger shaders, this allow
the renderer to reassemble large shaders and recombined
the chunks before passing them to the GLSL translation.
This also enhances the renderer protocol to allow
for some more info in the shader object, and removes
the separate vs/gs/fs variants in favour of a type field
in the shader.
This code ended up in the other file and really wasn't necessary
there.
Remove the transfer code from virglrenderer.c, move into main
renderer file, and match it with the corresponding transfer
reader.
This should at least fix the crash in compressed textures
with ARB_get_texture_sub_image
This fixes a number of issues with how transform feedback works
it does requires ARB_transform_feedback3 to work at all, but
hopefully this extension is widespread enough, if not we can
revisit later.
It uses transform feedback objects to store the stream out
state.
This merges the error/bounds checking on the transfer
code, but keeps the same API, it also uses a struct
to pass through the transfer info.
this also passes a return value out to make testing easier.
