This extension allows to control the subgroup size by allowing a varying subgroup size and also specifying a required subgroup size. This implementation only allows to specify a required subgroup size for compute shaders because there is some caveats with other shader stages (eg. NGG with geometry shader). This basically allows apps to use Wave32 for compute shaders. This extension is enabled for all chips but only GFX10 supports Wave32. ACO doesn't support it.
