[igt-dev] [PATCH i-g-t 01/11] trace.pl: Fix no context colouring mode

[Tvrtko Ursulin]

From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>

Commit 87d2affc380da96ba66c258c5337c363fe8651ef ("trace.pl: Add support
for colouring context execution"), due some dodgy attempts at patch
splitting broke the legacy colouring mode.

Fix it by passing in the request stage into the helper so all stages can
be correctly coloured in both modes.

[igt-dev] [PATCH i-g-t 02/11] trace.pl: Improve readability of graphical timeline representation

[Tvrtko Ursulin]

From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>

We add stripes for different stages of request execution so it is easier
to follow one context in the multi-colour mode.

Vertical stripe pattern indicates pipeline "blockages" - requests waiting
for dependencies before they are runnable.

Diagonal stripes indicate runnable requests waiting for GPU time.

Horizontal strips are requests executing on the GPU.

Also use this new multi-coloured mode from media-bench.pl.

v2:
 John Harrison:
 * Mention media-bench.pl in the commit.
 * Fix HTML for single colour mode.

v3:
 * Rebase.
 * Apply stripes to legacy colouring as well.

v4:
 John Harrison:
 * Use per context colours for ctxsave and incomplete boxes.
 * Clearer timeline legend.

In context colouring mode, the legend is not especially useful as it is 
only coloured for one particular context (which at least for all of my 
traces, is the system context that only appears at the very end as a 
flush) and has no indication that other contexts will be significantly 
different. Also, I find the black text is really hard to read against 
the dark colour backgrounds. Plus the boxes are too small to actually 
work out what the shading is (for 'ready' and 'incomplete' if not all of 
them).

See attached patch for some tweaks. Basically, add all contexts to the 
key in colour mode, make the boxes bigger and use white text for most of 
it. Although the thought occurs that it might be worth limiting the 
legend to only four or five contexts and just putting an 'etc' at the 
end if there are more. Otherwise a trace with hundreds of contexts could 
be a problem! I'm guessing in that case, the difference in colour from 
one context to the next will be pretty minimal anyway.

In context colouring mode, the legend is not especially useful as it is 
only coloured for one particular context (which at least for all of my 
traces, is the system context that only appears at the very end as a 
flush) and has no indication that other contexts will be significantly 
different. Also, I find the black text is really hard to read against 
the dark colour backgrounds. Plus the boxes are too small to actually 
work out what the shading is (for 'ready' and 'incomplete' if not all of 
them).

See attached patch for some tweaks. Basically, add all contexts to the 
key in colour mode, make the boxes bigger and use white text for most of 
it. Although the thought occurs that it might be worth limiting the 
legend to only four or five contexts and just putting an 'etc' at the 
end if there are more. Otherwise a trace with hundreds of contexts could 
be a problem! I'm guessing in that case, the difference in colour from 
one context to the next will be pretty minimal anyway.

[igt-dev] [PATCH i-g-t 03/11] trace.pl: Scale timeline for better precision

[Tvrtko Ursulin]

From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>

vis library has a limited precision compared to our trace data which
prevents zooming into the timeline and seeing the fine detail.

Scale the HTML view by a thousand to work around it.

Shouldn't there be some clue in the HTML as to the time scale?
Although it's quite easy to tally the numbers against the details to
work it out.

One clue is that each box contains it's duration. If that is not enough 
I can look into whether the timeline axis can be custom formatted. It 
would be useful in general to get rid of the annoying date based 
display, but no promises that it is possible.

Regards,

Tvrtko

Maybe add a comment to the HTML page's description text when scaling is 
enabled to say that the timeline units are not entirely accurate? 
Although, I guess the date was never actually correct in the first 
place! Either way...

[igt-dev] [PATCH i-g-t 04/11] trace.pl: Put single context at single vertical slot

[Tvrtko Ursulin]

From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>

Turn off timeline stacking in favour of putting all the boxes belonging to
a single context at the same vertical slot.

Also remove the custom sorting function in favour of correctly assigning
the subgroup id's and order which greatly speeds up the library operations.

And finally remove the 'Toggle stacking' button which never worked.

There is no chance that this will cause a problem due to sparse subgroup 
values? E.g. min_ctx is 5 and ctx is 500-510? This change certainly 
makes the charts a lot easier to understand, so it doesn't seem to be an 
issue. But it might be worth checking in the vis documentation if that 
is possible?

Otherwise...

[Tvrtko Ursulin]

From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>

Now that we scale timestamps to get better timeline granularity, the hacky
hand rolled micro-second time to HTML date conversion does no longer cut
it.

Use perl built-in gmtime to handle things properly.

Maybe not bother with the +1970 in the scaling case given that the whole 
date thing is meaningless when microseconds become milliseconds? 
Actually, even in the non-scaling case the epoch is actually whenever 
the traced system was last booted and not some specific calendar date.

Maybe not bother with the +1970 in the scaling case given that the whole 
date thing is meaningless when microseconds become milliseconds? 
Actually, even in the non-scaling case the epoch is actually whenever 
the traced system was last booted and not some specific calendar date. 
So maybe leaving out the offset regardless would make sense?

Again, a minor point so...

[igt-dev] [PATCH i-g-t 06/11] trace.pl: Improve context colouring for large context id's

[Tvrtko Ursulin]

From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>

John reports that on a long runnning systems the huge disparity between
kernel context and user context id's causes all interesting colours to be
clustered too close together.

Fix this by assigning colours to seen contexts instead of basing purely
on context id's.

Oops, I think I had already squashed this patch into patch #2 in my 
brain. So some of my comments (and certainly the legend tweak patch) 
probably apply to here instead. So I guess you might need to either 
split my comments/tweaks up across the two patches or possibly just 
squash this one into the other for real :).

[igt-dev] [PATCH i-g-t 08/11] trace.pl: Context save only applies to last request of a bunch

[Tvrtko Ursulin]

From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>

Skip accounting the context save time for anything but the last request of
the coalesced bunch, and also skip drawing those boxes on the timeline.

[igt-dev] [PATCH i-g-t 09/11] trace.pl: Fix incomplete request handling

[Tvrtko Ursulin]

From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>

Incomplete requests (no notify, no context complete) have to be corrected
by looking at the engine timeline, and not the sorted-by-start-time view
as was previously used.

Per-engine timelines are generated on demand and cached for later use.

v2: Find end of current context on the engine timeline instead of just
    using the next request for adjusting the incomplete start time.

v3: Improve scaling with large datasets by only walking each engine
    timeline once and some caching. (John Harrison)

v4:
 * Fix logic fail from v3.
 * Refactor the code a bit to separate the stages better.
 * Do not account batches with unknown duration in avg stats.
 * Handle two user interrupts with the same seqno.
 * Handle user interrupt arriving after request_out.

v5:
 * Update for class:instance.

[igt-dev] [PATCH i-g-t 11/11] trace.pl: Fix request split mode

[Tvrtko Ursulin]

From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>

Request split mode had several bugs, both in the original version and also
after the recent refactorings.

One big one was that it wasn't considering different submit ports as a
reason to split execution, and also that it was too time based instead of
looking at relevant timelines.

In this refactoring we address the former by using the engine timelines
introduced in the previous patch. Secondary port submissions are moved
to follow the preceding submission as a first step in the correction
process.

In the second step, we add context timelines and use then in a similar
fashion to separate start and end time of coalesced requests. For each
coalesced request we know its boundaries by looking at the engine
timeline (via global seqnos), and we know the previous request it should
only start after, by looking at the context timeline.

v2:
 * Remove some dead code.
 * Fix !port0 shifting logic.

v3:
 * Refactor for less list walking as with incomplete handling.

v4:
 * Database of context timelines should not contain duplicates!
   (Converted from array into a hash.)

v5:
 * Avoid over-accounting runnable time for a coalesced group by recording
   the time first request entered the GPU and ending the execute delay at
   that point for the whole group.

v6:
 * Update for engine class:instance.

[PATCH i-g-t 11/11] trace.pl: Fix request split mode

[Tvrtko Ursulin]

From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>

Request split mode had several bugs, both in the original version and also
after the recent refactorings.

One big one was that it wasn't considering different submit ports as a
reason to split execution, and also that it was too time based instead of
looking at relevant timelines.

In this refactoring we address the former by using the engine timelines
introduced in the previous patch. Secondary port submissions are moved
to follow the preceding submission as a first step in the correction
process.

In the second step, we add context timelines and use then in a similar
fashion to separate start and end time of coalesced requests. For each
coalesced request we know its boundaries by looking at the engine
timeline (via global seqnos), and we know the previous request it should
only start after, by looking at the context timeline.

v2:
 * Remove some dead code.
 * Fix !port0 shifting logic.

v3:
 * Refactor for less list walking as with incomplete handling.

v4:
 * Database of context timelines should not contain duplicates!
   (Converted from array into a hash.)

v5:
 * Avoid over-accounting runnable time for a coalesced group by recording
   the time first request entered the GPU and ending the execute delay at
   that point for the whole group.

v6:
 * Update for engine class:instance.
