After the removal of engine global seqnos and the corresponding
intel_engine_notify tracepoints the script needs to be adjusted to cope
with the new state of things.
To keep working it switches over using the dma_fence:dma_fence_signaled:
tracepoint and keeps one extra internal map to connect the ctx-seqno pairs
with engines.
It also needs to key the completion events on the full engine/ctx/seqno
tokens, and adjust correspondingly the timeline sorting logic.
v2:
* Do not use late notifications (received after context complete) when
splitting up coalesced requests. They are now much more likely and can
not be used.
v3:
* Pull a hunk which moved forward during rebases back here.
v4:
* Drop ctxengines approach since it cannot handle requests moving across
engines. ctx/seqno pair is unique anyway so enough.

Eeek.. let's try and not make the request tracing ability even more useless.
Because for trace.pl the decoupled from actual request completion nature
of dma_fence_signaled is depressing enough. I wonder how better tracing
tools view/cope with this.
And I'd also write to Santa to wire me up a real request start, to
distinguish semaphores vs batch execution. In the realm of impossible
wishes yeah.
Persistent breadcrumbs while tracing is another one for which even there
was a patch some time back.
Regards,
Tvrtko

You have the context id, which is supposed to be unique (so long as we don't
run for a few years, should be). Actually, wouldn't that be better here?

* [PATCH i-g-t 04/27] trace.pl: Virtual engine support
2019-05-20 14:47 ` [igt-dev] " Tvrtko Ursulin

From: Tvrtko Ursulin @ 2019-05-20 14:47 UTC (permalink / raw)
To: igt-dev; +Cc: Intel-gfx
From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>
Add virtual/queue timelines to both stdout and HTML output.
A new timeline is created for each queue/virtual engine to display
associated requests in queued and runnable states. Once requests are
submitted to a real engine for executing they show up on the physical
engine timeline.

@ 2019-05-20 14:47 ` Tvrtko Ursulin
0 siblings, 0 replies; 72+ messages in thread
From: Tvrtko Ursulin @ 2019-05-20 14:47 UTC (permalink / raw)
To: igt-dev; +Cc: Intel-gfx, Tvrtko Ursulin
From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>
Add virtual/queue timelines to both stdout and HTML output.
A new timeline is created for each queue/virtual engine to display
associated requests in queued and runnable states. Once requests are
submitted to a real engine for executing they show up on the physical
engine timeline.

From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>
Use the 'completed?' tracepoint field to detect more robustly when a
request has been preempted and remove it from the engine database if so.
Otherwise the script can hit a scenario where the same global seqno will
be mentioned multiple times (on an engine seqno) which aborts processing.

To: igt-dev; +Cc: Intel-gfx
From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>
We are moving towards bumping the uAPI headers more often instead of using
too much local struct/ioctl/param definitions since the latter are more
challenging for rebase and maintenance.

Add support for submit fences in a way similar to how normal input fences
are handled. Eg:
1.RCS.500-1000.0.0
1.VCS1.3000.s-1.0
1.VCS2.3000.s-2.0
Submit fences are signalled when the originating request enters the
submission backend.

+Engine maps
+-----------
+
+Engine maps are a per context feature which changes the way engine selection is
+done in the driver.
+
+Example:
+
+ M.1.VCS1|VCS2
+
+This sets up context 1 with an engine map containing VCS1 and VCS2 engine.
+Submission to this context can now only reference these two engines.
+
+Engine maps can also be defined based on class like VCS.
+
+Example:
+
+M.1.VCS
+
+This sets up the engine map to all available VCS class engines.

+-----------

+Engine maps are a per context feature which changes the way engine selection is

+This sets up context 1 with an engine map containing VCS1 and VCS2 engine.

+Engine maps can also be defined based on class like VCS.

+Example:

+M.1.VCS
+
+This sets up the engine map to all available VCS class engines.

We can improve the parsing loop readability a bit more by avoiding some
line breaks caused by explicit NULL checks.

Parsing an integer workload descriptor field is a common pattern which we
can extract to a helper macro and by doing so further improve the
readability of the main parsing loop.

From: Tvrtko Ursulin @ 2019-05-20 14:47 UTC (permalink / raw)
To: igt-dev; +Cc: Intel-gfx
From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>
A new workload command for enabling a load balanced context map (aka
Virtual Engine). Example usage:
B.1
This turns on load balancing for context one, assuming it has already been
configured with an engine map. Only DEFAULT engine specifier can be used
with load balanced engine maps.
v2:
* Lift restriction to only use load balancer when enabled in context map.
(Chris)

From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>
A new workload command for enabling a load balanced context map (aka
Virtual Engine). Example usage:
B.1
This turns on load balancing for context one, assuming it has already been
configured with an engine map. Only DEFAULT engine specifier can be used
with load balanced engine maps.
v2:
* Lift restriction to only use load balancer when enabled in context map.

This enables load balancing for context number one.
+
+Engine bonds
+------------
+
+Engine bonds are extensions on load balanced contexts. They allow expressing
+rules of engine selection between two co-operating contexts tied with submit
+fences. In other words, the rule expression is telling the driver: "If you pick
+this engine for context one, then you have to pick that engine for context two".
+
+Syntax is:
+ b.<context>.<engine_list>.<master_engine>
+
+Engine list is a list of one or more sibling engines separated by a pipe
+character (eg. "VCS1|VCS2").
+
+There can be multiple bonds tied to the same context.
+
+Example:
+
+ M.1.RCS|VECS
+ B.1
+ M.2.VCS1|VCS2
+ B.2
+ b.2.VCS1.RCS
+ b.2.VCS2.VECS
+
+This tells the driver that if it picked RCS for context one, it has to pick VCS1
+for context two. And if it picked VECS for context one, it has to pick VCS1 for
+context two.
+
+If we extend the above example with more workload directives:
+
+ 1.DEFAULT.1000.0.0
+ 2.DEFAULT.1000.s-1.0
+
+We get to a fully functional example where two batch buffers are submitted in a
+load balanced fashion, telling the driver they should run simultaneously and
+that valid engine pairs are either RCS + VCS1 (for two contexts respectively),
+or VECS + VCS2.
+
+This can also be extended using sync fences to improve chances of the first
+submission not getting on the hardware after the second one. Second block would
+then look like:
+
+ f
+ 1.DEFAULT.1000.f-1.0
+ 2.DEFAULT.1000.s-1.0

This enables load balancing for context number one.
+
+Engine bonds
+------------
+
+Engine bonds are extensions on load balanced contexts. They allow expressing
+rules of engine selection between two co-operating contexts tied with submit
+fences. In other words, the rule expression is telling the driver: "If you pick
+this engine for context one, then you have to pick that engine for context two".
+
+Syntax is:
+ b.<context>.<engine_list>.<master_engine>
+
+Engine list is a list of one or more sibling engines separated by a pipe
+character (eg. "VCS1|VCS2").
+
+There can be multiple bonds tied to the same context.
+
+Example:
+
+ M.1.RCS|VECS
+ B.1
+ M.2.VCS1|VCS2
+ B.2
+ b.2.VCS1.RCS
+ b.2.VCS2.VECS
+
+This tells the driver that if it picked RCS for context one, it has to pick VCS1
+for context two. And if it picked VECS for context one, it has to pick VCS1 for
+context two.
+
+If we extend the above example with more workload directives:
+
+ 1.DEFAULT.1000.0.0
+ 2.DEFAULT.1000.s-1.0
+
+We get to a fully functional example where two batch buffers are submitted in a
+load balanced fashion, telling the driver they should run simultaneously and
+that valid engine pairs are either RCS + VCS1 (for two contexts respectively),
+or VECS + VCS2.
+
+This can also be extended using sync fences to improve chances of the first
+submission not getting on the hardware after the second one. Second block would
+then look like:
+
+ f
+ 1.DEFAULT.1000.f-1.0
+ 2.DEFAULT.1000.s-1.0

* [PATCH i-g-t 18/27] gem_wsim: Infinite batch support

From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>
For simulating frame split workloads it is useful to express a batch which
ends at the same time as the parallel submission on the respective bonded
engine. For this we add support for infinite batch durations and the batch
terminate command ('T'). Syntax looks like this:
1.RCS.*.0.0
T.-1
First step starts an infinite batch, and second command terminates the
infinite batch with the usual relative workload step addressing.
v2: (Chris)
* Relax the recursive batch with 4096 nops between BB_START.
* Check for at least gen8.
* Simplify relocation entry building.

@ 2019-05-20 14:47 ` Tvrtko Ursulin
0 siblings, 0 replies; 72+ messages in thread
From: Tvrtko Ursulin @ 2019-05-20 14:47 UTC (permalink / raw)
To: igt-dev; +Cc: Intel-gfx, Tvrtko Ursulin
From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>
For simulating frame split workloads it is useful to express a batch which
ends at the same time as the parallel submission on the respective bonded
engine. For this we add support for infinite batch durations and the batch
terminate command ('T'). Syntax looks like this:
1.RCS.*.0.0
T.-1
First step starts an infinite batch, and second command terminates the
infinite batch with the usual relative workload step addressing.
v2: (Chris)
* Relax the recursive batch with 4096 nops between BB_START.
* Check for at least gen8.
* Simplify relocation entry building.

* [PATCH i-g-t 19/27] gem_wsim: Command line switch for specifying low slice count workloads
2019-05-20 14:47 ` [igt-dev] " Tvrtko Ursulin
@ 2019-05-20 14:47 ` Tvrtko Ursulin

From: Tvrtko Ursulin @ 2019-05-20 14:47 UTC (permalink / raw)
To: igt-dev; +Cc: Intel-gfx
From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>
A new command line switch ('-s') is added which toggles the low slice
count mode for workloads following on the command line.
This enables easy benchmarking of the effect of running the existing media
workloads in parallel against another client. For example:
./gem_wsim -n ... -v -r 600 -W master.wsim -s -w media_nn480.wsim
Adding or removing the '-s' switch before the second workload enables
analyzing the cost of dynamic SSEU switching impacted to the first
(master) workload.

@ 2019-05-20 14:47 ` Tvrtko Ursulin

From: Tvrtko Ursulin @ 2019-05-20 14:47 UTC (permalink / raw)
To: igt-dev; +Cc: Intel-gfx
From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>
A new command line switch ('-s') is added which toggles the low slice
count mode for workloads following on the command line.
This enables easy benchmarking of the effect of running the existing media
workloads in parallel against another client. For example:
./gem_wsim -n ... -v -r 600 -W master.wsim -s -w media_nn480.wsim
Adding or removing the '-s' switch before the second workload enables
analyzing the cost of dynamic SSEU switching impacted to the first
(master) workload.

+Context 1 is configured to run with one enabled slice (slice mask 1) and a batch

+This shows the dynamic SSEU reconfiguration cost beween two contexts competing

+Slice mask of -1 has a special meaning of "all slices". Otherwise any integer

To allow exercising the SSEU configuration in combination with Virtual
Engine, allow RCS to be specified in the engine map and use appropriate
index based addressing when applying SSEU configuration to it.

* [PATCH i-g-t 24/27] gem_wsim: Discover engines

Instead of hardcoding the VCS balancing engines, discover, both with the
new engines query, or with the legacy get_param in the fallback case, so
class based addressing always works.
v2:
* Simplify has_engine_query check. (Andi)
* Fix assert on uninitialized variable. (Andi)

Back when gem_wsim used forking it was safe to use the common storage
prng, but after converting to threads it no longer is.
Fix by storing and using a new per workload seed for batch buffer
duration randomness.
