X-Git-Tag: upstream/23.3.3~7056
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=d032de726ae0900c17d1d07f5c20fc901ba0c43f;p=platform%2Fupstream%2Fmesa.git

zink: massively shrink qbo size for timestamp queries

timestamp queries can only ever record a single value, so
the qbo only needs to be large enough for that single value

fixes #9092
