As one of those fences is the master submit fence, + * there is a delay on all secondary fences as the HW may be + * currently busy. Equally, as all the requests are independent, + * they may have other fences that delay individual request + * submission to HW. Ergo, we do not guarantee that all requests are + * immediately submitted to HW at the same time, just that if the + * rules are abided by, they are ready at the same time as the + * first is submitted. Userspace can embed semaphores in its batch + * to ensure parallel execution of its phases as it requires. + * Though naturally it gets requested that perhaps the scheduler should + * take care of parallel execution, even across preemption events on + * different HW. (The proper answer is of course "lalalala".) + * + * With the submit-fence, we have identified three possible phases + * of synchronisation depending on the master fence: queued (not + * ready), executing, and signaled. The first two are quite simple + * and checked below. However, the signaled master fence handling is + * contentious. Currently we do not distinguish between a signaled + * fence and an expired fence, as once signaled it does not convey + * any information about the previous execution. It may even be freed + * and hence checking later it may not exist at all. Ergo we currently + * do not apply the bonding constraint for an already signaled fence, + * as our expectation is that it should not constrain the secondaries + * and is outside of the scope of the bonded request API (i.e. all + * userspace requests are meant to be running in parallel).
