Subject: zink: change pipeline hashes to index based on vk primitive type
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=ced9e6e3e5c14a0f9b7e6d20d01a337227fcf40a;p=mesa.git

zink: change pipeline hashes to index based on vk primitive type

this is a bit more convenient since we always support vk types but not
necessarily gallium types
