bart: grow your own listify
|
|
bart imports listify from trappy.plotter.utils. trappy.plotter requires
matplotlib, which makes bart require matplotlib. For listify. Get your
own version of listify to avoid the cross-import.

sched: fix documentation

c9211760aa45 ("sched: SchedMultiAssert: Add missing pids argument")
called the pids argument "pids". Fix the documentation accordingly.

sched: SchedMultiAssert: Add missing pids argument

The class should accept either pids or execnames as specified in
the API reference. This fixes issue #23.

trappy has changed the API of stats.SchedConf in 0fce01a7dad8 ("stats:
SchedConf: Fix for period calculation"), the return value of period() is
changed. This is fixed in bart in 0e83faeeee8a ("sched: Use Median for
calculation of the period of a task").
|
|
We aim to maintain compatibility with Ubuntu 14.04 LTS which ships an
ipython that can only open notebooks with format 3.
|
|
sched: Use Median for calculation of the period of a task
|
|
Here is what I do for calculating the period of the task:
Let's say a task started execution at the following times
T_1, T_2, ...T_n
Currently for align = "start" the period is
Average of:
(T_2 - T_1), (T_4 - T_3), ....(T_n - T_{n-1})
In this method we have an edge condition when a task does not run
for a particular time or when it migrates between CPUs causing the
average to end up significantly higher than the actual period of
the task. However, as periodicity is statistical in nature
and can vary during the lifetime of the task, we can have a
good understanding of the periodicity by getting the median period
of the deltas above.

trappy has changed the API for EventPlot in f4eefc02239a ("plotter:
EventPlot: Allow specification of lane names") which will be released
in trappy 2.0. This is fixed in 5b1275f59fec ("sched: Update usage of
EventPlot API") in bart. Make sure bart the next version of bart
depends on the appropriate version of trappy.
