* main: allow NEAREST_MIPMAP_NEAREST for stencil texturingRoland Scheidegger2016-12-061-15/+8
| | | | | | | | | | | | As per GL 4.5 rules, which fixed a spec mistake in GL_ARB_stencil_texturing. The extension spec wasn't updated, but just allow it with older GL versions as well, hoping there aren't any crazy tests which want to see an error there... (Compile tested only.)

* main: Nameless texture creation and deletion. Does not affect normal ↵Laura Ekstrand2015-01-081-0/+7
| | | | | | | | | | | | | | | | | | | | creation and deletion paths. In implementing ARB_DIRECT_STATE_ACCESS functions, it is often necessary to abstract the functionality of a traditional GL API function into a backend that both the traditional and dsa API functions can share. For instance, glTexParameteri and glTextureParameteri both call _mesa_texture_parameteri, which takes a context object and a texture object as arguments. The existance of such backend functions provides the opportunity for driver internals (such as meta) to pass around the actual texture object rather than its ID or target, saving on texture object storage and look-up overhead. This patch provides nameless texture creation and deletion for meta. This will be used in an upcoming refactor of meta. Reviewed-by: Anuj Phogat <[email protected]>

| | | | | | | | | Most ARB_DIRECT_STATE_ACCESS functions take an object's ID and use it to look up the object in its hash table. If the user passes a fake object ID (ie. a non-generated name), the implementation should throw INVALID_OPERATION. This is a convenience function for texture objects.

* mesa: Add core API support for GL_ARB_stencil_texturing (from 4.3).Kenneth Graunke2014-03-041-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | While the GL_ARB_stencil_texturing extension does not allow the creation of stencil textures, it does allow shaders to sample stencil values stored in packed depth/stencil textures. Specifically, applications can call glTexParameter* with a pname of GL_DEPTH_STENCIL_TEXTURE_MODE and value of either GL_DEPTH_COMPONENT or GL_STENCIL_INDEX to select which component they wish to sample. The default value is GL_DEPTH_COMPONENT (for traditional depth sampling). Shaders should use an unsigned integer sampler (presumably usampler2D) to access stencil data. Otherwise, results are undefined. Using shadow samplers with GL_STENCIL_INDEX selected also is undefined behavior. This patch creates a new gl_texture_object field, StencilSampling, to indicate that stencil should be sampled rather than depth. (I chose to use a boolean since I figured it would be more convenient for drivers.) It also introduces the [Get]TexParameter code to get and set the value, and of course the extension plumbing. v2: Also consider textures incomplete when sampling stencil with non-NEAREST min/mag filters (caught by Eric Anholt).

* mesa: rework texture completeness testingBrian Paul2012-03-201-0/+13
| | | | | | | | | | | | | | | | | | | Instead of gl_texture_object::_Complete there are now two fields: _BaseComplete and _MipmapComplete. The former indicates whether the base texture level is valid. The later indicates whether the whole mipmap is valid. With sampler objects, a single texture can appear to be both complete and incomplete at the same time. See the GL_ARB_sampler_objects spec for more details. To implement this we now check if the texture is complete with respect to a sampler state. Another benefit of this is we no longer need to invalidate a texture's completeness state when we change the minification/magnification filters with glTexParameter().

* mesa: create/use a fallback texture when bound texture is incompleteBrian Paul2009-05-011-0/+3
| | | | | | | | | | | | | | When a GLSL sampler reads from an incomplete texture it should return (0,0,0,1). Instead of jumping through hoops in all the drivers to make this happen, just create/install a fallback texture with those texel values. Fixes piglit/fp-incomplete-tex on i965 and more importantly, fixes some GPU lockups when trying to sample from missing surfaces. If a binding table entry is NULL, it seems that sampling sometimes works, but not always (lockup). Todo: create a fallback texture for each type of texture target?
