X-Git-Tag: upstream/21.0.0~4703
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=9a8539206f98111314e4295736e790eae20f2c2c;p=platform%2Fupstream%2Fmesa.git

zink: fix shader buffer size caps to use 65536

using max(Uniform|Storage)BufferRange yields some insane values that aren't
consistent with reality

affects PIPE_CAP_MAX_SHADER_BUFFER_SIZE and PIPE_SHADER_CAP_MAX_CONST_BUFFER_SIZE
