Rather than the rings, which weren't shared between userspace and kernel space in Zephyr like they are in Linux with io_uring, use atomic mpsc queues for submission and completion queues. Most importantly this removes a potential head of line blocker in the submission queue as the sqe would be held until a task is completed. As additional bonuses this avoids some additional locks and restrictions about what can be submitted and where. It also removes the need for two executors as all chains/transactions are done concurrently. Lastly this opens up the possibility for a common pool of sqe's to allocate from potentially saving lots of memory. Signed-off-by: Tom Burdick <thomas.burdick@intel.com> |
