From: Kevin Strasser Date: Fri, 12 Aug 2016 21:17:20 +0000 (-0700) Subject: anv/x11: Add support for Xlib platform X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=71258e9462c9cfb4c8b567713af5018928ef744d;p=mesa.git anv/x11: Add support for Xlib platform Some applications continue to use the Xlib client library and expect that VK_KHR_xlib_surface will be available in the driver. Service these applications by converting the Display pointer to xcb_connection_t and use the existing xcb code in the driver.
