From 71258e9462c9cfb4c8b567713af5018928ef744d Mon Sep 17 00:00:00 2001 From: Kevin Strasser Date: Fri, 12 Aug 2016 14:17:20 -0700 Subject: [PATCH] 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.
