Subject: radv: add support for using addrlib max alignment.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=edf2acbeb16112fe002d3f7208018273d413f25c;p=mesa.git

radv: add support for using addrlib max alignment.

Rather than using 64k, use what addrlib returns as the base
alignment for vulkan allocations.
