In commit 9b6586ae9f6b ("drm/i915: Keep a global seqno per-engine"), we
moved from a global inflight counter to per-engine counters in the
hope that will be easy to run concurrently in future. However, with the
advent of the desire to move requests between engines, we do need a
global counter to preserve the semantics that no engine wraps in the
middle of a submit. (Although this semantic is now only required for gen7
semaphore support, which only supports greater-then comparisons!)
v2: Keep a global counter of all requests ever submitted and force the
reset when it wraps.

In the next patch, rings are the central timeline as requests may jump
between engines. Therefore in the future as we retire in order along the
engine timeline, we may retire out-of-order within a ring (as the ring now
occurs along multiple engines), leading to much hilarity in miscomputing
the position of ring->head.
As an added bonus, retiring along the ring reduces the penalty of having
one execlists client do cleanup for another (old legacy submission
shares a ring between all clients). The downside is that slow and
irregular (off the critical path) process of cleaning up stale requests
after userspace becomes a modicum less efficient.
In the long run, it will become apparent that the ordered
ring->request_list matches the ring->timeline, a fun challenge for the
future will be unifying the two lists to avoid duplication!
v2: We need both engine-order and ring-order processing to maintain our
knowledge of where individual rings have completed upto as well as
knowing what was last executing on any engine. And finally by decoupling
retiring the contexts on the engine and the timelines along the rings,
we do have to keep a reference to the context on each request
(previously it was guaranteed by the context being pinned).

We don't need to track every ring for its lifetime as they are managed
by the contexts/engines. What we do want to track are the live rings so
that we can sporadically clean up requests if userspace falls behind. We
can simply restrict the gt->rings list to being only gt->live_rings.
v2: s/live/active/ for consistency with gt.active_requests

To: intel-gfx
In the future, we want to move a request between engines. To achieve
this, we first realise that we have two timelines in effect here. The
first runs through the GTT is required for ordering vma access, which is
tracked currently by engine. The second is implied by sequential
execution of commands inside the ringbuffer. This timeline is one that
maps to userspace's expectations when submitting requests (i.e. given the
same context, batch A is executed before batch B). As the rings's
timelines map to userspace and the GTT timeline an implementation
detail, move the timeline from the GTT into the ring itself (per-context
in logical-ring-contexts/execlists, or a global per-engine timeline for
the shared ringbuffers in legacy submission.
The two timelines are still assumed to be equivalent at the moment (no
migrating requests between engines yet) and so we can simply move from
one to the other without adding extra ordering.
v2: Reinforce that one isn't allowed to mix the engine execution
timeline with the client timeline from userspace (on the ring).

From: Chris Wilson @ 2018-04-23 18:08 UTC (permalink / raw)
To: intel-gfx
We need to move to a more flexible timeline that doesn't assume one
fence context per engine, and so allow for a single timeline to be used
across a combination of engines. This means that preallocating a fence
context per engine is now a hindrance, and so we want to introduce the
singular timeline. From the code perspective, this has the notable
advantage of clearing up a lot of mirky semantics and some clumsy
pointer chasing.
By splitting the timeline up into a single entity rather than an array
of per-engine timelines, we can realise the goal of the previous patch
of tracking the timeline alongside the ring.

From: Chris Wilson @ 2018-04-23 18:08 UTC (permalink / raw)
To: intel-gfx
When userspace is passing around swapbuffers using DRI, we frequently
have to open and close the same object in the foreign address space.
This shows itself as the same object being rebound at roughly 30fps
(with a second object also being rebound at 30fps), which involves us
having to rewrite the page tables and maintain the drm_mm range manager
every time.
However, since the object still exists and it is only the local handle
that disappears, if we are lazy and do not unbind the VMA immediately
when the local user closes the object but defer it until the GPU is
idle, then we can reuse the same VMA binding. We still have to be
careful to mark the handle and lookup tables as closed to maintain the
uABI, just allowing the underlying VMA to be resurrected if the user is
able to access the same object from the same context again.
If the object itself is destroyed (neither userspace keeping a handle to
it), the VMA will be reaped immediately as usual.
In the future, this will be even more useful as instantiating a new VMA
for use on the GPU will become heavier. A nuisance indeed, so nip it in
the bud.
v2: s/__i915_vma_final_close/i915_vma_destroy/ etc.

* [PATCH] drm/i915: Split i915_gem_timeline into individual timelines
2018-04-23 18:08 ` [PATCH v2 5/6] drm/i915: Split i915_gem_timeline into individual timelines Chris Wilson

From: Chris Wilson @ 2018-04-23 23:11 UTC (permalink / raw)
To: intel-gfx
We need to move to a more flexible timeline that doesn't assume one
fence context per engine, and so allow for a single timeline to be used
across a combination of engines. This means that preallocating a fence
context per engine is now a hindrance, and so we want to introduce the
singular timeline. From the code perspective, this has the notable
advantage of clearing up a lot of mirky semantics and some clumsy
pointer chasing.
By splitting the timeline up into a single entity rather than an array
of per-engine timelines, we can realise the goal of the previous patch
of tracking the timeline alongside the ring.
v2: Tweak wait_for_idle to stop the compiling thinking that ret may be
uninitialised.

I agree that checking both simultaneously would be useful, but we do
check both for cross-consistency already, just not in the same place.
It's just doing so in a readable fashion.
After this we aren't using active_requests as more than a boolean; so
I'm wondering if not just replacing it with list_empty(&active_rings)
for the infrequent uses.

I didn't really figure out what was wrong with v1? Neither could handle
more than four billion of simultaneously active requests - but I thought
that should not concern us. :)
I don't quite get wrapping based on otherwise unused counter.
v1 made sense to wrap then any engine timeline couldn't handle all
active requests without wrapping.

It was still using the local engine->timeline.seqno as it's base. If we
swapped from one at 0 to another at U32_MAX, we would overflow much
later in submission; after the point of no return.

Emphasis on *any*, not just the current engine.

By swapped you already refer to engine change? Ok, I can see that yes.
In this case global counter does prevent that.
In the light of that, what is your current thinking with regards to
mixing engine classes?
If the thinking is still to only allow within a class then per-class
seqno counter would be an option.

That classes are a hw limitation that doesn't impact on balancing itself,
just which engines the user is allowed to put into the same group.

> seqno counter would be an option.
The goal of localising the seqno here was to try and reduce the locking
requirements (or at least make it easier to reduce them in future).
Whether it's one u32 across all engines, or one u32 across a few isn't
enough for me to worry. The breadcrumb tracking should be happy enough
(sorted by i915_seqno_passed rather than absolute u32) so the only
limitation in wrapping should be gen7 HW semaphores. Hmm, with a bit of
thought, I believe we can reduce the wrap logic to simply skip semaphore
sync inside the danger zone. Would be worth the effort.

I was thinking about reducing the number of global seqno resets as much
as we can in general. For instance would it be possible to keep using
the gt.active_requests together with a new gt.max_engine_seqno? The
latter would be the maximum last allocated seqno from the engine
timelines. This way reset would be much less frequent if the load is
distributed over engines (divided by num engines less frequent).

Tvrtko

I win with a divide by 0 with removing the global seqno and wrap. :-p
The frequency we are talking about is a short wrap (will take as long as
the active request takes to sync) approximately every 47 days divided by
N engines. The cost of contention on struct_mutex must surely outweigh
that during those 47/N days...

You may be right, but where did 47 days come from? :)
