* i965: Request lowering gl_VertexIDIan Romanick2014-09-101-0/+1
| | | | | | | | | | | | | Fixes the (new) piglit tests gles-3.0-drawarrays-vertexid, gl-3.0-multidrawarrays-vertexid, and gl-3.2-basevertex-vertexid.

* i965: Expose gl_BaseVertex via a vertex attribute.Kenneth Graunke2014-09-103-20/+65
| | | | | | | | | | | | | | | | | | | Now that we have the data available, we need to expose it to the shaders. We can reuse the same vertex element that we use for gl_VertexID, but we need to back it by an actual vertex buffer. A hardware restriction requires that vertex attributes coming from a buffer (STORE_SRC) must come before any other types (i.e. STORE_0). So, we have to make gl_BaseVertex be the .x component of the vertex attribute. This means moving gl_VertexID to a different component. I chose to move gl_VertexID and gl_InstanceID to the .z and .w components, respectively, to make room for gl_BaseInstance in the .y component (which would also come from a buffer, and therefore be STORE_SRC).

* i965: Refactor Gen4-7 VERTEX_BUFFER_STATE emission into a helper.Kenneth Graunke2014-09-101-30/+47
| | | | | | | | | We'll need to emit another VERTEX_BUFFER_STATE for gl_BaseVertex; pulling this into a helper function will save us from having to deal with cross-generation differences in that code. Signed-off-by: Kenneth Graunke <[email protected]> Reviewed-by: Ian Romanick <[email protected]>

| | | | | | | | | | | This will be used for GL_ARB_shader_draw_parameters, as well as fixing gl_VertexID, which is supposed to include gl_BaseVertex's value. For indirect draws, we simply point at the indirect buffer; for normal draws, we upload the value via the upload buffer.

* mesa: Fix glGetActiveAttribute for gl_VertexID when lowered.Kenneth Graunke2014-09-101-1/+13
| | | | | | | | | | | | | The lower_vertex_id pass converts uses of the gl_VertexID system value to the gl_BaseVertex and gl_VertexIDMESA system values. Since gl_VertexID is no longer accessed, it would not be considered active. Of course, it should be, since the shader uses gl_VertexID. v2: Move the var->name dereference past the var != NULL check.

Fix suggested by Marek. v3: Reabase on Matt's foreach_in_list changes (was using foreach_list). v4 (Ken): Use a systemvalue instead of a uniform because STATE_BASE_VERTEX has been removed. v5: Use a boolean to select lowering, and only allow one lowering method. Suggested by Ken. v6 (Ken): Replace strcmp against literal "gl_BaseVertex"/"gl_VertexID" with SYSTEM_VALUE enum checks, for efficiency. v7: Rebase on context constant initialization work.

* freedreno: don't overflow cmdstream buffer so muchRob Clark2014-09-091-0/+15
| | | | | | | | | | | | | | We currently aren't too clever about dealing with running out of cmdstream buffer space. Since we use a single buffer for both drawing and tiling commands, we need to ensure there is enough space at the tail of the cmdstream buffer to fit the tiling commands. Until we get more clever, the easy solution is a threshold to trigger flushing rendering even if the application does not trigger flush (swap, changing render target, etc). This way we at least don't crash for apps that do several thousand draw calls (like some piglit tests do). Signed-off-by: Rob Clark <[email protected]>

But without the cp stage, the shaders the new compiler produces are still better (perf and correctness) than the old compiler. So a simple thing to do until I have more time to work on it is first trying falling back to new compiler without cp, before finally falling back to old compiler.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Excess conversions considered harmful. Recently Matt reworked the boolean uniform handling to use the value of UniformBooleanTrue, rather than integer 1, when uploading uniforms: mesa: Upload boolean uniforms using UniformBooleanTrue. glsl: Use UniformBooleanTrue value for uniform initializers. Marek then set the default to 1.0f for drivers without native integer support: mesa: set UniformBooleanTrue = 1.0f by default However, ir_to_mesa was assuming a value of integer 1, and arranging for it to be converted to 1.0f on upload. Since Marek's commit, we were uploading 1.0f = 0x3f800000 which was being interpreted as the integer value 1065353216 and converted to float as 1.06535322E9, which broke assumptions in ir_to_mesa that "true" was exactly 1.0f. +13 Piglits on classic swrast (fs-bool-less-compare-true, {vs,fs}-op-not-bool-using-if, glsl-1.20/execution/uniform-initializer).
