...ies implements a new IOCTL to submit push buffers that can optionally return a sync FD or sync object to userspace. This is useful in cases where userspace wants to synchronize operations between the GPU and another driver (such as KMS for display). Among other things this allows extensions such as eglDupNativeFenceFDANDROID to be implemented. Note that patch 4 modifies the ABI introduced in patch 3 by allowing DRM sync objects to be passed rather than only sync FDs. It also allows any number of sync FDs/objects to be passed in or emitted. I think those are useful features, but I left them in a separate patch in case...
