[PATCH v9 00/15] V4L2 Explicit Synchronization
Hi all, Gustavo has asked to me to take care of the final issues with this series. I'm working on adding some fences tests to v4l2-compliance, which I'll be posting shortly. So, here's a new version of the "video4linux meet fences" series. This new round hopefully addresses all the feedback received in v8. There are some additional changes: * Removed the vb2_ops_is_unordered callback, and instead use a simpler unordered bitfield. After inspecting the code, I really saw no reason for having a callback. Please correct me if I missed anything. * Reworked the out-fence setup in vb2_core_qbuf, which results in getting rid of the sync_file state. After inspecting the code, it became apparent that the sync_file wasn't meant to be part of the buffer state. The resulting code is simpler. * Avoid returning fence file descriptors anywhere but in the QBUF result. Also, fixed the documentation to be clear about this. Worth mentioning, I've decided to drop the is-signaled flag suggested by Hans. It'll be easier to review and merge if we keep this simple. We can always add stuff later.
