* mesa: Add shader storage buffer support to struct gl_contextIago Toral Quiroga2015-07-141-0/+2
| | | | | | | | | | | This includes the array of bindings, the current buffer bound to the GL_SHADER_STORAGE_BUFFER target and a set of general limits and default values for shader storage buffers. v2: - Use spec values for the new defined constants (Jordan) Reviewed-by: Jordan Justen <[email protected]>
* mesa: remove some MAX_NV_FRAGMENT_PROGRAM_* macrosBrian Paul2015-06-091-11/+2

* mesa: Add support for the ARB_pipeline_statistics_query extensionBen Widawsky2015-02-171-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | This was originally part of a single patch which added the extension, and implemented it for i965 classic. For information about the evolution of the patch, please see the subsequent commit. One difference here as compared to the original mega patch is this does build support for the compute shader query. Since it cannot be tested on any platform, it will always return NULL for now. Jordan has already written a patch to address this, and when that patch lands, this logic can be modified. v2: Fix typo in subject (Brian Paul) Add checks for desktop gl (Ilia) Fail for any callers for now (Ilia) Update QueryCounterBits for new tokens (Ilia) Jordan: Use _mesa_has_compute_shaders Signed-off-by: Ben Widawsky <[email protected]> Reviewed-by: Ilia Mirkin <[email protected]> v3: Rebased on patch which adds the proper information to unstub tessellation shaders.

* mesa: Add core support for the GL_INTEL_performance_query extension.Petri Latvala2014-05-021-0/+8
| | | | | | | | | | | | | | | | | | | | | 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]>

| | | | | | | | | | | | | | | | | | | These limits will be queryable by GL_MAX_VIEWPORTS, GL_VIEWPORT_SUBPIXEL_BITS, and GL_VIEWPORT_BOUNDS_RANGE. Drivers that actually implement the extension must set values for these constants that comply with the minimum-maximums from the spec. Most of these changes were part of other patches. They were separated out because it make reordering of later patches easier. Also, MaxViewports wasn't set by that patch, and I completely overlooked it in review. It's now obvious that it's set. :) v2 (idr): Split these changes out from the original patches. Keep MaxViewportWidth and MaxViewportHeight as GLuint.

It defines the necessary data structures for tracking atomic counter buffer objects (from now on "ABOs") associated with some specific context or shader program, it implements support for binding buffers to an ABO binding point and querying the existing atomic counters and buffers declared by GLSL shaders. v2: Fix extension checks.

| | | | | | | | | | | | | We've never properly supported more than one address register.

| | | | | | | | | | | | This is a cleanup for ARB_transform_feedback3, where GL_MAX_TRANSFORM_FEEDBACK_BUFFERS is introduced for interleaved attribs and has the same meaning as GL_MAX_.._SEPARATE_ATTRIBS for separate attribs. Also, the maximum number of TFB buffers is reduced from 32 to 4, which makes this patch useful even without the extension. I don't know of any hardware which can do more than 4.

| | | | | | | | | | | This allows 16K x 16K 2D textures, for example, but we don't want to allow that for 3D textures. The new gl_constants::MaxTextureMBytes field is used to prevent allocating too large of texture image. This allows a 16K x 32 x 32 3D texture, for example, but prevents 16K^3. Drivers can override this limit. The default is currently 1GB. Apps should use the proxy texture mechanism to determine the actual max texture size.

Note that this may result in DRI drivers that don't set this limit having an improbable return (fragment + vertex < combined), but it seems like it shouldn't cause problems for apps.
* Merge branch 'outputswritten64'Ian Romanick2009-11-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | Add a GLbitfield64 type and several macros to operate on 64-bit fields. The OutputsWritten field of gl_program is changed to use that type. This results in a fair amount of fallout in drivers that use programs. No changes are strictly necessary at this point as all bits used are below the 32-bit boundary. Fairly soon several bits will be added for clip distances written by a vertex shader. This will cause several bits used for varyings to be pushed above the 32-bit boundary. This will affect any drivers that support GLSL. At this point, only the i965 driver has been modified to support this eventuality. I did this as a "squash" merge. There were several places through the outputswritten64 branch where things were broken. I foresee this causing difficulties later for bisecting. The history is still available in the branch.

* ARB prog: Change handling of program parameter limitsIan Romanick2009-08-261-17/+39
| | | | | | | | | | | | | | | | | Several changes are made to program parameter limits. Several of the non-NATIVE limits are set higher. All of the NATIVE limits are set to zero in the core Mesa code. Each driver must set the actual value in its context creation routine. If the NATIVE value remains zero, this indicates that hardware shaders may not be supported. Each of the preceeding changes matches the bahavior of Apple's shader assembler, so it seems safe. Finally, we limit the value of MaxEnvParams to be no greater than MaxNativeAttribs. At least one case has been found where an application does the wrong thing if MaxNativeAttribs < MaxEnvParams. See also bugzilla #23490.
