This provides most of the implementation, but there are some things we cannot enable until we improve of kernel submit interface, namely: We don't expose capacity to export SYNC_FD, although we do have the implementation in place. This requires that we improve our kernel interface and event wait implementation first so we can cover the corner case where the application submits a command buffer that includes a VkCmdWaitForEvents and tries to export a SYNC_FD from its signal semaphores or fence before it the event is signaled and the command buffer is sent to the kernel for execution in full. Likewise, we can't currently import semaphores. This is because our current kernel submit interface can only take one syncobj. We have been working around this so far by waiting on the last syncobj produced from the device whenever we had to wait on any semaphores (which is obviously suboptimal already), but this won't work as soon as we allow importing external semaphores, as those could (and would typically) be produced from a different device. Once we address the kernel bits, we should come back and enable SYNC_FD exports as well as semaphore imports. Relevant CTS tests: dEQP-VK.api.external.fence.* dEQP-VK.api.external.semaphore.* dEQP-VK.synchronization.cross_instance.* Reviewed-by: Alejandro Piñeiro <apinheiro@igalia.com> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/11105> |
