This makes the xshmfence stuff only used if the driver specifies it, allowing drivers to specify other FD-passing based fences, and also avoiding errors if a driver doesn't initialize any FD-passing based fences.
Without these changes, the X server will crash when an application creates an xshmfence object and passes that to the X server to a driver that has no DRI3 FD passing support. -keith _______________________________________________ xorg-devel@lists.x.org: X.Org development Archives: http://lists.x.org/archives/xorg-devel Info: http://lists.x.org/mailman/listinfo/xorg-devel
