Subject: intel: Sync a synchronized READ_BIT map buffer range with GL drawing to it.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=82313eed01b191320721dab63d353a1634f89231;p=mesa.git

intel: Sync a synchronized READ_BIT map buffer range with GL drawing to it.

It's probably uncommon, but would obviously have gone wrong.
