* st/mesa: handle failed context creation for core profileBrian Paul2014-09-111-1/+4
| | | | | | | | | | | | If the glx/wgl state tracker requested a core profile but the gallium driver did not support some feature of GL 3.1 or later, we were setting ctx->Version=0 and then failing the assertion in _mesa_initialize_exec_table(). With this change we check for ctx->Version=0 and tear down the context and return NULL from st_create_context(). Reviewed-by: Marek Olšák <[email protected]>
* glsl: Add a lowering pass for gl_VertexIDIan Romanick2014-09-101-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | Converts gl_VertexID to (gl_VertexIDMESA + gl_BaseVertex). gl_VertexIDMESA is backed by SYSTEM_VALUE_VERTEX_ID_ZERO_BASE, and gl_BaseVertex is backed by SYSTEM_VALUE_BASE_VERTEX. v2: Put the enum in struct gl_constants and propoerly resolve the scope in C++ code. 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.

* main/extensions: Add early extension override structuresJordan Justen2014-06-161-0/+2
| | | | | | | | | | | | | | | | | | | | | | | During the early one_time_init phase of context creation, we initialize two global gl_extensions structures. We read the MESA_EXTENSION_OVERRIDE environment variable, and store positive and negative overrides in two structures: * struct gl_extensions _mesa_extension_override_enables * struct gl_extensions _mesa_extension_override_disables These are filled before the driver initializes extensions and constants, therefore the driver can make adjustments based on the desired overrides. This can be useful during development of a new extension where the extension is only partially ready. The driver can't actually advertise support for the extension, but if it sees that the override is set for the extension, then it can expose more supported parts of the extension, such as upgrading context constants.

* Add the EGL_MESA_configless_context extensionNeil Roberts2014-03-121-20/+62
| | | | | | | | | | | | | | | | | | | | This extension provides a way for an application to render to multiple surfaces with different buffer formats without having to use multiple contexts. An EGLContext can be created without an EGLConfig by passing EGL_NO_CONFIG_MESA. In that case there are no restrictions on the surfaces that can be used with the context apart from that they must be using the same EGLDisplay. _mesa_initialze_context can now take a NULL gl_config which will mark the context as ‘configless’. It will memset the visual to zero in that case. Previously the i965 and i915 drivers were explicitly creating a zeroed visual whenever 0 is passed for the EGLConfig. Mesa needs to be aware that the context is configless because it affects the initial value to use for glDrawBuffer. The first time the context is bound it will set the initial value for configless contexts depending on whether the framebuffer used is double-buffered.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This 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. Counters are also organized into groups. Applications create "performance monitor" objects, select the counters they want to track, and Begin/End monitoring, much like OpenGL's query API. Multiple monitors can be in flight simultaneously. v2: Pass ctx to all driver hooks (suggested by Christoph), and attempt to fix overallocation of bitsets (caught by Christoph). Incomplete. v3: Significantly rework core data structures. Store counters in groups rather than in a global list. Use their array index in the group's counter list as the ID rather than trying to store a globally unique counter ID. Use bitsets for active counters within a group, and also track which groups are active so that's easy to query. v4: Remove _mesa_ prefix on static functions; detect out of memory conditions in new_performance_monitor(); make BeginPerfMonitor hook return a boolean rather than setting m->Active or raising an error. Switch to GLuint/unsigned for NumGroups, NumCounters, and MaxActiveCounters (which also means switching a bunch of temporary variable types). All suggested by Brian Paul. Also, remove commented out code at the bottom of the block. Finally, fix the dispatch sanity test (noticed by Ian Romanick).
