* mesa: Make glGetIntegerv(GL_*_ARRAY_SIZE) return GL_BGRA.José Fonseca2014-06-031-0/+10
| | | | | | | | | | | | | | | | | | | | | Same as b026b6bbfe3f15c8a7296ac107dc3d31f74e401e, but COLOR_ARRAY_SIZE/SECONDARY_COLOR_ARRAY_SIZE. Ideally we wouldn't munge the incoming state, so that we wouldn't need to unmunge it back on glGet*. But the array size state is copied and referred in many places, many of which couldn't take an GLenum like GL_BGRA instead of a plain integer. So just hack around on glGet*, to ensure there is no risk of introducing regressions elsewhere. This bug causes problems to Apitrace, resulting in wrong traces. See https://github.com/apitrace/apitrace/issues/261 for details. Tested with piglit arb_vertex_array_bgra-get, which was created for this purpose.

* mesa: Add core support for the GL_INTEL_performance_query extension.Petri Latvala2014-05-021-0/+1
| | | | | | | | | | | | | | | | | | | | | Like AMD_performance_monitor, this extension provides an interface for applications (and OpenGL-based tools) to access GPU performance counters. Since the exact performance counters available vary between vendors and hardware generations, the extension provides an API the application can use to get the names, types, and minimum/maximum values of all available counters. Applications create performance queries based on available query types, and begin/end measurement collection. Multiple queries can be measuring simultaneously. v2: Whitespace changes v3: src/mapi/glapi/gen/gl_API.xml: Also expose the functions to GLES2. v4: Whitespace changes, static_dispatch="false" for all functions, fix dispatch_sanity test for GLES2 functions Signed-off-by: Petri Latvala <[email protected]> Reviewed-by: Ian Romanick <[email protected]>

* mesa: use accessors for struct gl_debug_stateChia-I Wu2014-04-271-15/+1
| | | | | | | | | | | | | | | | When GL_DEBUG_OUTPUT_SYNCHRONOUS is GL_TRUE, drivers are allowed to log debug messages from other threads. That requires gl_debug_state to be protected by a mutex, even when it is a context state. While we do not spawn threads in Mesa yet, this commit makes it easier to do when we want to. Since the definition of struct gl_debug_state is no longer needed by the rest of the driver, move it to main/errors.c. This should make it even harder to use the struct incorrectly. v2: add comments for the accessors Signed-off-by: Chia-I Wu <[email protected]> Reviewed-by: Brian Paul <[email protected]>

The sizeof(gl_debug_state) is huge (~285KB on 64-bit systems), not even counting the 54(!) hash tables and lists that it contains.

* mesa: Rename ElementArrayBufferObj to IndexBufferObj.Kenneth Graunke2014-02-031-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | DirectX and most hardware documentation use the term "Index Buffer" to refer to a buffer containing indexes into arrays of vertex data, which allows random access to vertex data, rather than sequential access. OpenGL uses a different term for this concept: "Element Array Buffer". However, "Index Buffer" has become much more widespread. A quick Google search shows 29,300 hits for "Element Array Buffer" vs. 82,300 hits for "Index Buffer." Arguably, "Index Buffer" is clearer: an "element of an array" (or list) usually refers to an actual item stored in the array, not the index used to refer to it. The terminology is also already used in Mesa: some VBO module code for dealing with ElementArrayBufferObj names local variables "ib".

| | | | | | | | | | | | | | | | | | | | | | | | | | | | When reading through the Mesa drawing code, it's not immediately obvious to me that "ArrayObj" (gl_array_object) is the Vertex Array Object (VAO) state. The comment above the structure explains this, but readers still have to remember this and translate accordingly. Out of context, "array object" is a fairly vague. Even in context, "array" has a lot of meanings: glDrawArrays, vertex data stored in user arrays, gl_client_arrays, gl_vertex_attrib_arrays, and so on. Using the term "VAO" immediately associates these fields with the OpenGL concept, clarifying the situation and aiding programmer sanity.

| | | | | | | | | | | | | | | | | | | | | | Previously, we assumed that the only way Mesa would expose geometry shader support was via the ARB_geometry_shader4 extension. But this extension has some extra complications over GL 3.2 (interactions with compatibility-only features, and link-time initialization of the constant gl_VerticesIn). So we want to allow for the possibility of supporting GL 3.2 (with GLSL 1.50 style geometry shaders) even if ctx->Extensions.ARB_geometry_shader4 is false. This patch adds a new function, _mesa_has_geometry_shaders(), which returns true if either ARB_geometry_shader4 is supported or the GL version is at least 3.2 desktop. Since compute_version() only enables GL 3.2 functionality when GLSL 1.50 support is present, a sufficient way for a back-end to advertise geometry shader support is to set ctx->Const.GLSLVersion >= 150. v2: Remove unnecessary ctx->Const.GeometryShaders150 constant.
