From: Duncan Hopkins Date: Thu, 11 Jul 2019 10:51:08 +0000 (+0100) Subject: zink: respect ubo buffer alignment requirement X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=5cf93985a00b80b27ea19a8dae0d77e6dae3331a;p=mesa.git zink: respect ubo buffer alignment requirement The driver can report a minimum alignment for UBOs, and that can be larger than 64, which we've currently been using. Let's play ball, and use the reported value instead.
