* mesa/formatquery: limit ES target support, fix core context supportIlia Mirkin2016-09-061-7/+8
| | | | | | | | | | | | | | | | | First off, as late as ES 3.2, GetInternalformat only supports RENDERBUFFER and 2DMS(_ARRAY) targets. Secondly, the _mesa_has_ext helpers are very accurate... a little too accurate, some might say. If we only show an extension in compat profiles because core profiles have the functionality guaranteed, they will return false. Fix these to either check for a core profile explicitly, or to a different-but-identical extension available in core profile.

* mesa/formatquery: expand NUM_SAMPLE_COUNTS OpenGL ES commentAlejandro Piñeiro2016-06-031-0/+3
| | | | | | | | | | | | | | | For ES 3.0 NUM_SAMPLE_COUNTS spec points that some formats will be always zero. But on ES 3.1 can be different to zero. The current code is correctly checking exactly against version 3.0, but the comment only mentions 3.0 spec.

* mesa/formatquery: added FILTER pname supportAlejandro Piñeiro2016-03-031-1/+19
| | | | | | | | | | | | | | | | | | | | | It discards out the targets and internalformats that explicitly mention (per-spec) that doesn't support filter types other than NEAREST or NEAREST_MIPMAP_NEAREST. Those are: * Texture buffers target * Multisample targets * Any integer internalformat For the case of multisample targets, it was used the existing method _mesa_target_allows_setting_sampler_parameter. This would scalate better in the future if new targets appear that doesn't allow to set sampler parameters. We consider RENDERBUFFER to support LINEAR filters, because although it doesn't support this filter for sampling, you can set LINEAR on a blit operation using glBlitFramebuffer.

* mesa/formatquery: support for MAX_COMBINED_DIMENSIONSAlejandro Piñeiro2016-03-031-9/+81
| | | | | | | | | | | | | | | | | | | | It is implemented combining the values returned by calls to the 32-bit query _mesa_GetInternalformati32v. The main reason is simplicity. The other option would be C&P how we implemented the support of GL_MAX_{WIDTH/HEIGHT/DEPTH} and GL_SAMPLES. Additionally, doing this way, we avoid adding checks on the code, as are done by the call to the query itself. MAX_COMBINED_DIMENSIONS is the only pname pointed on the spec of needing a 64-bit query. We handle that possibility by packing the returning value on the two first 32-bit integers of params. This would work on the 32-bit query as far as the value is not greater that INT_MAX. On the 64-bit query wrapper we unpack those values in order to get the final value. Reviewed-by: Dave Airlie <airlied@redhat.com>

All those pnames are used to get the maximum value for each dimension of the given target. The only difference between this calls and calling GetInteger with pnames like GL_MAX_TEXTURE_SIZE, GL_MAX_3D_TEXTURE_SIZE, etc is that GetInternalformat allows to specify a internalformat. But at this moment, there is no reason to think that the values would be different based on the internalformat. The spec already take that into account, using these specific pnames as example on Issue 7 of arb_internalformat_query2 spec. So this seems like a hook to allow to return different values based on the internalformat in the future. It is worth to note that the piglit test associated to those pnames are checking the returned values of GetInternalformat against the values returned by GetInteger, and the test is passing with NVIDIA proprietary drivers. main/formatquery: support for MAX_{WIDTH/HEIGHT/DEPTH/LAYERS} Implemented by calling GetIntegerv with the equivalent pname and handling individually the exceptions related to dimensions.

This is equivalent to calling GetTexParameter with <value> set to IMAGE_FORMAT_COMPATIBILITY_TYPE." Current implementation of GetTexParameter for this case returns a field of a texture object, so the support of this pname was implemented creating a temporal texture object and returning that value. It is worth to mention that right now that field is not reassigned after initialization. So it is somehow hardcoded. An alternative option would be return that value.

* mesa/formatquery: handle unmodified buffer for SAMPLES on the 64-bit queryAlejandro Piñeiro2016-03-031-3/+14
| | | | | | | | | | | | | | | | | | | | From arb_internalformat_query2 spec: " If <internalformat> is not color-renderable, depth-renderable, or stencil-renderable (as defined in section 4.4.4), or if <target> does not support multiple samples (ie other than TEXTURE_2D_MULTISAMPLE, TEXTURE_2D_MULTISAMPLE_ARRAY, or RENDERBUFFER), <params> is not modified." So there are cases where the buffer should not be modified. As the 64-bit query is a wrapper over the 32-bit query, we can't just copy the values to the equivalent 32-bit buffer, as that would fail if the original params contained values greater that INT_MAX. So we need to copy-back only the values that got modified by the 32-bit query. We do that by filling the temporal buffer by negatives, as the 32-bit query should not return negative values ever.

* mesa/formatquery: Remove tracking of number of elements in the responseEduardo Lima Mitev2016-03-031-6/+5
| | | | | | | | | | | | | | | | | Currently, the number of integers returned in the response to GetInternalFormativ is being tracked by a 'count' variable. This is so only the modified elements from the temporary buffer are copied into the original user buffer. However, with the introduction of ARB_internalformat_query2, keeping track of 'count' would complicate the code a lot, considering the high number of queries. So, we propose to forget about tracking count, and move all the 16 elements in the temporary buffer, back to the user buffer (clamped to user buffer size of course). This is basically a trade-off between performance and code clarity. Reviewed-by: Dave Airlie <airlied@redhat.com>

This fixes a slew of dEQP-GLES31.functional.state_query.internal_format.* tests, which now all pass.
