X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=24765c58bd7b041f92ff51ec354f5d6b0ce35daa;p=mesa.git i965/gen6+: Support 128 varying components. GL 3.2 requires us to support 128 varying components for geometry shader outputs and fragment shader inputs, and 64 varying components otherwise. But there's no hardware limitation that restricts us to 64 varying components, and core Mesa doesn't currently allow different stages to have different maximum values, so just go ahead and enable 128 varying components for all stages. This gets us better test coverage anyway. Even though we are only working on GL 3.2 support for gen7 right now, gen6 also supports 128 varying components, so go ahead and switch it on there too.
