* 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 <[email protected]>

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.

| | | | | | | | | | | | | | | | | | | | | | | From arb_internalformat_query2 spec: "IMAGE_FORMAT_COMPATIBILITY_TYPE: The matching criteria use for the resource when used as an image textures is returned in <params>. 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. That doesn't seems really scalable though. v2: use _mesa_has## instead of direct ctx->Extensions access (Nanley Chery) Reviewed-by: Dave Airlie <[email protected]>
* 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.

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 <[email protected]>
