* i965: Restyle brw_disasm.c.Kenneth Graunke2014-06-301-1234/+1231
| | | | | | | | | | | | | | | | | | | | brw_disasm.c basically wasn't following the Mesa coding style at all. It used 4-space indent instead of 3-space, didn't cuddle braces, didn't put function return types on a separate line, put extra spaces in function calls (between the name and parenthesis), and a number of other things. This made it fairly obnoxious to work on, since my editor is configured to follow Mesa style in the Mesa source repository. Fixing it to follow a consistent style now should save time dealing with it later. These modifications were originally generated by: $ indent -br -i3 -npcs -ce -cs -l80 --no-tabs with some manual changes afterwards to fit our style better.

* meta: Use AMD_vertex_shader_layer instead of a GS for layered clears.Kenneth Graunke2014-06-301-37/+16
| | | | | | | | | | | | | | | | | | | | | | | On i965, enabling and disabling the GS is not free: you have to do a full pipeline stall, reconfigure the URB and push constant space, and emit a bunch of state. Most clears aren't layered, so the GS isn't needed in the common case. But we turned it on universally. Using AMD_vertex_shader_layer allows us to skip setting up the GS altogether, while achieving the same effect. According to Ilia, current nVidia GPUs can't do AMD_vertex_shader_layer. However, since nouveau is Gallium-based, they're unlikely to ever care about this path. Intel and AMD GPUs both support the extension. Since i965 is the only driver using this path which does layered rendering, we may as well target it at that. v2: Improve commit message. No code changes.

* i965: Implement GL_PRIMITIVES_GENERATED with non-zero streams.Iago Toral Quiroga2014-06-302-7/+26
| | | | | | | | | | | | | | | | | So far we have been using CL_INVOCATION_COUNT to resolve this query but this is no good with streams, as only stream 0 reaches the clipping stage. Instead we will use SO_PRIM_STORAGE_NEEDED which can keep track of the primitives sent to each individual stream. Since SO_PRIM_STORAGE_NEEDED is related to the SOL stage and according to ARB_transform_feedback3 we need to be able to query primitives generated in each stream whether transform feedback is active or not what we do is to enable the SOL unit even if transform feedback is not active but disable all output buffers in that case. This effectively disables transform feedback but permits activation of statistics enabling SO_PRIM_STORAGE_NEEDED even when transform feedback is not active.
