X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=1eb58960bfd30d575cca4fa3c600512751aab467;p=mesa.git i965: Do not store SRC after 0 on component control. The PRM SKL-Vol 2b-05.16 says: "Within a VERTEX_ELEMENT_STATE structure, if a Component Control field is set to something other than VFCOMP_STORE_SRC, no higher-numbered Component Control fields may be set to VFCOMP_STORE_SRC. In other words, only trailing components can be set to something other than VFCOMP_STORE_SRC." Since we set the component 1 to VFCOMP_STORE_0 on gen8+, and VFCOMP_STORE_IID on gen5+, and we are not using components 2 and 3, let's also set them to VFCOMP_STORE_0.
