From: Jason Ekstrand Date: Sat, 12 Nov 2016 16:43:54 +0000 (-0800) Subject: anv/pipeline: Unify 3DSTATE_VS emission X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=4a48d19d936baacaaf49ffb3ed8b152f59213564;p=mesa.git anv/pipeline: Unify 3DSTATE_VS emission With this commit, a few fields are now specified on gen7 which weren't before. However, the values specified are zero which is the default so the final hardware packet remains the same. Reviewed-by: Timothy Arceri Reviewed-by: Kristian H.
