* mesa: Add color renderable/texture filterable format info for ES 3.x.Kenneth Graunke2016-03-181-0/+7
| | | | | | | | | | | | OpenGL ES 3.x contains a table of sized internal formats and their required properties. In particular, each format is marked as "Color Renderable" or "Texture Filterable". This patch introduces two functions that can be used to query the information from that table.

* mesa: Move _mesa_base_tex_format() from teximage to glformats filesEduardo Lima Mitev2015-09-281-0/+2
| | | | | | | | | | | | | | | | | This function will be needed as part of validating the combination of format, type and internal format of texture pixel operations, which happens in glformats files. Specifically, we want to be able to obtain the base format of a resolved effective internal format, to compare it with the original internal format passed. Also, since this function deals solely with GL formats, it fits better in glformats where the rest of similar format functionality rests. The function is moved as-is, without any modification.

* Remove _mesa_is_type_integer and _mesa_is_enum_format_or_type_integerNeil Roberts2014-06-131-6/+0
| | | | | | | | | | | | | | | | | | | | | | | The comment for _mesa_is_type_integer is confusing because it says that it returns whether the type is an “integer (non-normalized)” format. I don't think it makes sense to say whether a type is normalized or not because it depends on what format it is used with. For example, GL_RGBA+GL_UNSIGNED_BYTE is normalized but GL_RGBA_INTEGER+GL_UNSIGNED_BYTE isn't. If the normalized comment is just a mistake then it still doesn't make much sense because it is missing the packed-pixel types such as GL_UNSIGNED_INT_5_6_5. If those were added then it effectively just returns type != GL_FLOAT. That function was only used in _mesa_is_enum_format_or_type_integer. This function effectively checks whether the format is non-normalized or the type is an integer. I can't think of any situation where that check would make sense. As far as I can tell neither of these functions have ever been used anywhere so we should just remove them to avoid confusion. These functions were added in 9ad8f431b2a47060bf05517246ab0fa8d249c800.

* mesa: Fix computation of default vertex attrib stride for 2_10_10_10 formats.Paul Berry2012-12-131-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, if the client program didn't specify a stride when setting up a vertex attribute, we used _mesa_sizeof_type() to compute the size of the type, and multiplied it by the number of components. This didn't work for the 2_10_10_10 formats, since _mesa_sizeof_type() returns -1 for those types, resulting in all kinds of havoc, since it was causing the hardware to be programmed with a negative stride value. This patch adds a new function _mesa_bytes_per_vertex_attrib(), which is similar to the existing function _mesa_bytes_per_pixel(), but which computes the size of a vertex attribute based on the type and the number of formats. For packed formats (currently only the 2_10_10_10 formats), it verifies that the number of components is correct and returns the size of the packed format. For unpacked formats, it returns the size of the type times the number of components. In addition, this patch adds an assertion so that if we ever forget to update _mesa_bytes_per_vertex_attrib() when adding a new vertex format, we'll see the problem quickly rather than having to debug a subtle conformance test failure. Fixes GLES3 conformance tests vertex_type_2_10_10_10_rev_{conversion,divisor,stride_pointer}.test. Reviewed-by: Brian Paul <brianp@vmware.com>
