* mesa: Fix performance query id checkRobert Bragg2017-03-011-2/+6
| | | | | | | | | | | | | | | | | | | | The queryid_valid() function asserts that an ID given by an application isn't zero since the spec explicitly reserves an ID of zero as invalid. The implementation was written as if the ID was a signed integer and based on the assumption that queryid_to_index() is simply subtracting one from the ID. It was broken because in fact the ID was stored in an unsigned int and testing for an index >= 0 would always succeed. This adds a spec quote to clarify why zero is considered invalid and checks for zero before even passing the ID to queryid_to_index() for then checking the upper bound.

* st/mesa: inform the driver of framebuffer changes before compute dispatchesNicolai Hähnle2017-03-011-1/+9
| | | | | | | | | | | | | | | | | | | Even though compute shaders cannot access the framebuffer, there is a synchronization issue when a compute dispatch accesses a texture that was previously bound and drawn to as a framebuffer. Section 9.3 (Feedback Loops Between Textures and the Framebuffer) of the OpenGL 4.5 spec rather implicitly clarifies that undefined behavior results if the texture is still attached to the currently bound framebuffer. However, the feedback loop is broken when the application changes the framebuffer binding before a compute dispatch, and the state tracker needs to let the driver known about this.

However, this is going to change in a later patch, so we need to explicitly set the proper source type. brw_vec8_grf() creates an float type's fs_reg by default, when the ICP handle is actually unsigned.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of using the same backend interface as AMD_performance_monitor this defines a dedicated INTEL_performance_query interface that is modelled more on the ARB_query_buffer_object interface (considering the similarity of the extensions) with the addition of vfuncs for initializing and enumerating query and counter info. Compared to the previous backend, some notable differences are: - The backend is free to represent counters using whatever data structures are optimal/convenient since queries and counters are enumerated via an iterator api instead of declaring them using structures directly shared with the frontend. This is also done to help us support the full range of data and semantic types available with INTEL_performance_query which is awkward while using a structure shared with the AMD_performance_monitor backend since neither extension's types are a subset of the other. - The backend must support waiting for a query instead of the frontend simply using glFinish(). - Objects go through 'Active' and 'Ready' states consistent with the query object backend (hopefully making them more familiar). There is no 'Ended' state (which used to show that a query has ended at least once for a given object). There is a new 'Used' state, set when a query is first begun which implies that we are expecting to get results back for the object at some point. There's no equivalent to the 'EverBound' state since the spec doesn't require there to be a limbo state between generating IDs and associating them with an object on query Begin. The INTEL_performance_query and AMD_performance_monitor extensions are now completely orthogonal within Mesa main (though a driver could optionally choose to implement both extensions within a unified backend if that were convenient for the sake of sharing state/code). v2: (Samuel Pitoiset) - init PerfQuery.NumQueries in frontend - s/return_string/output_clipped_string/ - s/backed/backend/ typo - remove redundant *bytesWritten = 0 v3: - Add InitPerfQueryInfo for lazy probing of available queries v4: - Clean up some internal usage of GL typedefs (Ken) Signed-off-by: Robert Bragg <[email protected]> Reviewed-by: Lionel Landwerlin <[email protected]> Reviewed-by: Kenneth Graunke <[email protected]>

| | | | | | | | | | | | | | | | | To allow the backend interfaces for AMD_performance_monitor and INTEL_performance_query to evolve independently based on the more specific requirements of each extension this starts by separating the frontends of these extensions.

| | | | | | | | | | | | | | | | | | | | | | The only feature over and above ES 3.0 is DrawTransformFeedback(). We already have to do the whole SOL_NUM_PRIMS_WRITTEN counter dance in order to compute the SVBI value for ResumeTransformFeedback(), at which point our existing GetTransformFeedbackVertexCount() implementation will do the trick (though with a stall to CPU map the buffer). Someday, we could probably implement DrawTransformFeedback() more efficiently, using the "Load Internal Vertex Count" feature of 3DSTATE_SVB_INDEX and the 3DPRIMITIVE indirect vertex count bit. Rumor has it this allows people to use WebGL 2.0 on Sandybridge. Note that we don't need pipelined register writes like Gen7+ because we use the 3DSTATE_SVB_INDEX command rather than MI_LOAD_REGISTER_MEM.

| | | | | | | | | | | | | | | | | | | | | | | This fixes Piglit's ARB_transform_feedback2/change-objects-while-paused GLES 3.0 test. When resuming the transform feedback object, we need to reset the SVBI counters so we continue writing at the correct point in the buffer. Instead of SO_WRITE_OFFSET counters (with a DWord offset), we have the Streamed Vertex Buffer Index (SVBI) counters, which contain a count of vertices emitted. Unfortunately, there's no straightforward way to store the current SVBI counter values to a buffer. They're not available in a register. You can use a bit in the 3DSTATE_SVB_INDEX packet to copy them to another internal counter which 3DPRIMITIVE can use...but there's no good way to extract that either. So, once again, we use SO_NUM_PRIMS_WRITTEN to calculate the vertex numbers. Thankfully, we can reuse most of the existing Gen7+ code.
