vbo: Readd the arrays argument to the legacy draw methods.

The legacy draw paths from back before 2012 contained a gl_vertex_array
array for the inputs to be used for draw. So all draw methods from legacy
drivers and everything that goes through tnl are originally written
for this calling convention. The same goes for tools like t_rebase or
vbo_split*, that even partly still have the original calling convention
with a currently unused such pointer.
Back in 2012 patch 50f7e75

mesa: move gl_client_array*[] from vbo_draw_func into gl_context

introduced Array._DrawArrays, which was something that was IMO aiming for
a similar direction than Array._DrawVAO introduced recently.
Now several tools like t_rebase and vbo_split*, which are mostly used by
tnl based drivers, would need to be converted to use the internal
Array._DrawVAO instead of Array._DrawArrays. The same goes for the driver
backends that use any of these tools.
Alternatively we can reintroduce the gl_vertex_array array in its call
argument list and put these tools finally into the tnl directory.
So this change reintroduces this gl_vertex_array array for the legacy
draw paths that are still required for the tools t_rebase and vbo_split*.
A followup will move vbo_split also into tnl.

Note that none of the affected drivers use the DriverFlags.NewArray
driver bit. So it should be safe to remove this also for the legacy
draw path.

6 years agoi965: initialize SPIR-V capabilities
Alejandro Piñeiro [Sat, 14 Oct 2017 07:23:24 +0000 (09:23 +0200)]
i965: initialize SPIR-V capabilities

Needed for ARB_gl_spirv. Those are not the same that the Intel vulkan
driver. From the ARB_spirv_extensions spec:

   "3. If a new GL extension is added that includes SPIR-V support via
   a new SPIR-V extension does it's SPIR-V extension also get
   enumerated by the SPIR_V_EXTENSIONS_ARB query?.

   RESOLVED. Yes. It's good to include it for consistency. Any SPIR-V
   functionality supported beyond the SPIR-V version that is required
   for the GL API version should be enumerated."

So in addition to the core SPIR-V support, there is the possibility of
specific GL extensions enabling specific SPIR-V extensions (so
capabilities). That would mean that it is possible that OpenGL and
Vulkan not having the same capabilities supported, even for the same
driver. For this reason it is better to keep them separated.

As an example: at the time of this patch writing Intel vulkan driver
support multiview, but there isn't any OpenGL multiview GL extension
supported.

Note: we initialize SPIR-V capabilities at brwCreateContext instead of
the usual brw_initialize_context_constants because we want to do that
only if the extension is enabled.

   * Rebase update (SpirVCapabilities not a pointer anymore)
   * Fill spirv capabilities for OpenGL >= 3.3 (Ian Romanick)

v3:
