Allow multiple requests to be queued unto a virtual engine, whereas
before we only allowed a single request to be queued at a time. The
advantage of keeping just one request in the queue was to ensure that we

of the virtual

Now that we no longer switch back and forth between guc and execlists,
we no longer need to restore the backend's vfunc and can leave them set
after initialisation. The only catch is that we lose the submission on
wedging and still need to reset the submit_request vfunc on unwedging.
The core of the scheduling algorithm is that we compute the topological
order of the fence DAG. Knowing that we have a DAG, we should be able to
use a DFS to compute the topological sort in linear time. However,
during the conversion of the recursive algorithm into an iterative one,

For a modeset/pageflip, there is a very precise deadline by which the

A key prolem with legacy ring buffer submission is that it is an inheret
FIFO queue across all clients; if one blocks, they all block. A
scheduler allows us to avoid that limitation, and ensures that all
clients can submit in parallel, removing the resource contention of the
global ringbuffer.
When we are not using semaphores with a context/engine, we can simply
reuse the same seqno location across wraps, but we still require each
timeline to have its own address. For LRC submission, each context is
prefixed by a per-process HWSP, which provides us with a unique location
for each
The first "scheduler" was a topographical sorting of requests into
priority order. The execution order was deterministic, the earliest
submitted, highest priority request would be executed first. Priority
inheritance ensured that inversions were kept at bay, and allowed us to
dynamically boost
If any engine asks for the tasklet to be kicked from the CS interrupt,
do so. Currently, this is used by the execlists scheduler backends to
feed in the next request to the HW, and similarly could be used by a
ring scheduler, as will be seen in the next patch.
