Subject: iris: Increase BATCH_SZ to 64kB
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=382f92a81436a78f059daae86b4dfd2845635f92;p=mesa.git

iris: Increase BATCH_SZ to 64kB

This seems to improve performance by roughly ~1% across the board.
Thanks to Rafael Antognolli and Dan Walsh for their help tuning.
