Subject: radv: change base aligmment for allocated memory.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=06ffd299252311f57feac4474551bd5b44d3d4d4;p=mesa.git

radv: change base aligmment for allocated memory.

On some CIK (Hawaii) this needs to be at least 64k, I'm not 100% sure
it doesn't need to be 128k.

This was causing fast clear eliminate to overwrite the previous buffer,
which since my gfx init code, was the indirect buffer.
