| | | | | | | | | | Use NULL tests of the form `if (ptr)' or `if (!ptr)'. They do not depend on the definition of the symbol NULL. Further, they provide the opportunity for the accidental assignment, are clear and succinct. Signed-off-by: Edward O'Callaghan <[email protected]> Signed-off-by: Marek Olšák <[email protected]>
* softpipe: use provoking vertex for layerRoland Scheidegger2015-12-041-2/+2

* softpipe/llvmpipe: don't advertize support for ASTCRoland Scheidegger2015-11-241-1/+2
| | | | | | | | | 33339775565154040e0c4ea2e196217dccc08cdf added support for ASTC textures to gallium. They don't have any helpers hooked up for software decoding, however, so cannot support them in drivers relying on util code for decoding.

* gallium/swrast: fix front buffer blitting. (v2)Dave Airlie2015-10-311-4/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | So I've known this was broken before, cogl has a workaround for it from what I know, but with the gallium based swrast drivers BlitFramebuffer from back to front or vice-versa was pretty broken. The legacy swrast driver tracks when a front buffer is used and does the get/put images when it is mapped/unmapped, so this patch attempts to add the same functionality to the gallium drivers. It creates a new context interface to denote when a front buffer is being created, and passes a private pointer to it, this pointer is then used to decide on map/unmap if the contents should be updated from the real frontbuffer using get/put image. This is primarily to make gtk's gl code work, the only thing I've tested so far is the glarea test from https://github.com/ebassi/glarea-example.git v2: bump extension version, check extension version before calling get image.

* softpipe: fix using non-zero layer in non-array view from array resourceRoland Scheidegger2015-10-242-9/+31
| | | | | | | | | | | | For vertex/geometry shader sampling, this is the same as for llvmpipe - just use the original resource target. For fragment shader sampling though (which does not use first-layer based mip offsets) adjust the sampling code to use first_layer in the non-array cases. While here also fix up some code which looked wrong wrt buffer texel fetch (no piglit change). Reviewed-by: Dave Airlie <[email protected]> Reviewed-by: Jose Fonseca <[email protected]>

* softpipe: Constify variablesKrzesimir Nowak2015-09-111-242/+199
| | | | | | | | | This commit makes a lot of variables constant - this is basically done by moving the computation to variable definition.

| | | | | | | | | | | Add a small inline function doing the casting - this is to make sure we don't do a cast from some completely unrelated type. This commit does not make tgsi_sampler parameters const in vfuncs themselves for now - probably llvmpipe would need looking at before making such a change.

* softpipe: Split 3D to 2D coords conversion into separate functionKrzesimir Nowak2015-09-102-51/+45
| | | | | | | | | | | | | | | | | | | This is to avoid tying the conversion to the sampling - textureQueryLod will need to do the conversion too, but it does not do any sampling. So instead of a "get_samples" vfunc, there is just a bool saying whether the conversion is needed or not. This solution keeps a nice property of not adding any overhead for the common case (2D textures). v2: - replaced the "convert_coords" vfunc with a "need_cube_convert" boolean to avoid overhead of copying arrays in common case - removed an unused typedef - splitted too long lines in convert_cube - const fixes in convert_cube Reviewed-by: Brian Paul <[email protected]>

* softpipe: Put mip_filter_func inside a structKrzesimir Nowak2015-09-102-12/+38
| | | | | | | | | | | | | | | | | Putting this function pointer into a struct enables grouping of several related functions in a single place. For now it is just a single function, but the struct will be later extended with a mip_level_func for returning relative mip level. v2: - renamed sp_mip struct to sp_filter_funcs - renamed sp_filter_funcs instances from mip_foo to funcs_foo - splitted too long lines - sp_sampler now holds a pointer to sp_filter_funcs instead of an instance of it - some const fixes Reviewed-by: Brian Paul <[email protected]>

This fixes the offset calculations in a number of areas by adding the offset first, it also fixes the fastpaths, which I forgot to address in the previous commit. v2: try and avoid divides in most paths, the repeat mirror path really was ugly no matter which way I went, so I left it having the divide.

* softpipe: enable ARB_texture_viewRoland Scheidegger2015-05-135-124/+179
| | | | | | | | | | | | | | | | | | | | | | Some bits were already there for texture views but some were missing. In particular for cube map views things needed to change a bit. For simplicity I ended up removing the separate face addr bit (just use the z bit) - cube arrays didn't use it already, so just follow the same logic there. (In theory using separate bits could allow for better hash function but I don't think anyone ever did some measurements of that so probably not worth the trouble, if we'd reintroduce it we'd certainly wanted to use the same logic for cube arrays and cube maps.) Also extend the seamless cube sampling to cube arrays - as there were no piglit failures before this is apparently untested, but things now generally work quite the same for cube textures and cube array textures so there hopefully shouldn't be any trouble... 49 new piglits, 47 pass, 2 fail (both due to fake multisampling). v2: incorporate Brian's feedback, add sampler view validation, function rename, formatting fixes.
