This little series adds support for the VK_KHR_external_fence family of extensions. Most of the real work in implementing these extensions is actually in the kernel. Once we have a DRM_SYNCOBJ_IOCTL_WAIT that does what we need, the userspace bits are fairly straightforward. This series can be found as a branch here:
