From: Jesse Barnes Date: Tue, 10 Nov 2009 21:28:01 +0000 (-0800) Subject: DRI2: add SwapInterval support X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=efc82e7c703f9160cfdbe6d97e166ca6f5e75d86;p=mesa.git DRI2: add SwapInterval support Add support for the DRI2SwapInterval protocol request. This allows direct rendered clients to control their swap interval per the SGI_swap_control extension.
