* mesa: Add a _mesa_is_format_color_format helperJason Ekstrand2015-01-122-0/+22

* mesa: Let _mesa_get_format_base_format also handle mesa_array_format.Iago Toral Quiroga2015-01-122-4/+74
| | | | | | | | | | | | | | | | | | | | | | If we need the base format for a mesa_array_format we have to find the matching mesa_format first. This is expensive because it requires to loop through all existing mesa formats until we find the right match. We can resolve the base format of an array format directly by looking at its swizzle information. Also, we can have _mesa_get_format_base_format accept an uint32_t which can pack either a mesa_format or a mesa_array_format and resolve the base format for either type. This way clients do not need to check if they have a mesa_format or a mesa_array_format and call different functions depending on the case. Another reason to resolve the base format for array formats directly is that we don't have matching mesa_format enums for every possible array format, so for some GL format/type combinations we can produce array formats that don't have a corresponding mesa format, in which case we would not be able to find the base format. Example format=GL_RGB, type=GL_UNSIGNED_SHORT. This type would map to something like MESA_FORMAT_RGB_UNORM16, but we don't have that. Reviewed-by: Jason Ekstrand <[email protected]>
* main: Add a concept of an array formatJason Ekstrand2015-01-123-1/+209
| | | | | | | | | | | | | | | | | | | | An array format is a 32-bit integer format identifier that can represent any format that can be represented as an array of standard GL datatypes. Whie the MESA_FORMAT enums provide several of these, they don't account for all of them. v2 by Iago Toral Quiroga <[email protected]>: - Implement mesa_array_format as a plain bitfiled uint32_t type instead of using a struct inside a union to access the various components packed in it. This is necessary to support bigendian properly, as pointed out by Ian. - Squashed: Make float types normalized v3 by Iago Toral Quiroga <[email protected]>: - Include compiler.h in formats.h, which is necessary to build in MSVC as indicated by Brian Paul.

* mesa: Fix _mesa_swizzle_and_convert integer conversions to clamp properlySamuel Iglesias Gonsalvez2015-01-122-53/+94
| | | | | | | | | | | | | | | | | | | | | | | | | Fix various conversion paths that involved integer data types of different sizes (uint16_t to uint8_t, int16_t to uint8_t, etc) that were not being clamped properly. Also, one of the paths was incorrectly assigning the value 12, instead of 1, to the constant "one". v2: - Create auxiliary clamping functions and use them in all paths that required clamp because of different source and destination sizes and signed-unsigned conversions. v3: - Create MIN_INT macro and use it. v4: - Add _mesa_float_to_[un]signed() and mesa_half_to_[un]signed() auxiliary functions. - Add clamp for float-to-integer conversions in _mesa_swizzle_and_convert() Signed-off-by: Samuel Iglesias Gonsalvez <[email protected]> Reviewed-by: Jason Ekstrand <[email protected]>

* mesa: Fix incorrect assertion in init_teximage_fields_msIago Toral Quiroga2015-01-121-1/+1
| | | | | | | | | | | | | | | | _BaseFormat is a GLenum (unsigned int) so testing if its value is greater than 0 to detect the cases where _mesa_base_tex_format returns -1 doesn't work. Fixing the assertion breaks the arb_texture_view-lifetime-format piglit test on nouveau, since that test calls _mesa_base_tex_format with GL_R16F with a context that does not have ARB_texture_float, so it returns -1 for the BaseFormat, which was not being caught properly by the ASSERT in init_teximage_fields_ms until now.

| | | | | | | | | | | | | | | | | | | | 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]>
