2015-04-29Import libxshmfence-1.2 from pkgsrc-wip as x11/libxshmfence.tnn1-0/+14
(needed to build DRI3 support in MesaLib and modular-xorg-server on Linux) This library offers a CPU-based synchronization primitive compatible with the X SyncFence objects that can be shared between processes using file descriptor passing. There are three underlying implementations: 1) On Linux, the library uses futexes 2) On FreeBSD, the library uses umtx 3) On other systems, the library uses posix mutexes and condition variables.
