FIX

CapacitySanity._from_target() was reusing the passed collector multiple
times, leading to only the last trace being saved.

Instead, use the collector once and do all the work while collecting.

FIX

Ensure that LISA's FtraceCollector provides a reusable context manager.
Currently, the LISA kernel module will only get loaded the first time
the collector is used.

Fix that by not resetting the object state too much.

FIX

The 'self' in WACollectorBase refers to the WACollectorBase and not the
parent WAOutput, currently causing get_collector to crash because it
can't find the _jobs property.
This looks like an omission from the recent wa.py changes so this commit
just fixes the property being accessed.

FIX

Ensure compatibilty with older versions of devlib, which includes what
is currently published on PyPI.

FEATURE

Avoid breakage of published package at the next major pandas release,
since pandas more or less follows semantic versionning.

DataFrame.pivot(index=None) seems to have changed behavior:
https://github.com/pandas-dev/pandas/issues/52436

Remove index=None so that it works across pandas versions.

BREAKING CHANGE

Use the more descriptive "power" column name than "value".

FIX

FIX

Pandas 2.0.0 has changed the behavior of iterating over groupby() when
passed a list with a single item in it: it is now returning 1-tuple for
the key, instead of the value directly.

Patch all the sites where this is done to work with both pandas 1.5 and
2.0

FIX

Ensure we get the expected behavior now that pandas 2.0.0 is out and
group_keys default has changed to True.

Mismatching split BTF loading issue:

https://bugzilla.opensuse.org/show_bug.cgi?id=1194501

has been fixed in:
https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next.git/commit/?id=5e214f2e43e4

When that config is enabled: MODULE_ALLOW_BTF_MISMATCH=y

Unfortunately, that is not the default so keep LISA's current behavior.

FIX

When FtraceCollector.get_data() is called after the kernel module
unload, the event format is missing and the trace is therefore broken
(appears to not contain that event).

Close that gap by raising an explicit error in that scenario.

FIX

FtraceCollector.get_data() yields a broken trace when some events are
coming from the kernel modules, since the trace is extracted from the
kernel after the module has been unloaded so the event format is
unknown.

FEATURE

from_sysfs_headers() uses both /proc/config.gz and
/sys/kernel/kheaders.tar.xz to patch the user-provided tree. If that
results in a build failure, the fallback is from_user_tree() that just
asssumes the tree is ready.

If the tree is almost ready but the config is wrong, the module build
using from_user_tree() might error if e.g. a config option such as
CONFIG_SCHED_AUTOGROUP is enabled in the .config but not on the board,
leading to trying to access to a non-existant struct member that will
still be defined from BTF blob.

Instead of falling back to from_user_tree() straight away, fall back
first to from_proc_config() that will use /proc/config.gz, which is very
likely to be successful and has much higher chances of producing a
working module.

FIX

Module building fails with modpost error due to undefined symbols unless
KBUILD_MODPOST_WARN=1 is enabled, which turns the errors into warnings.
This is because modpost cannot know the list of symbols if
Module.symvers is missing, which is the case since we don't have a built
Image to work with.

FIX

Using named ring buffer in ftrace makes trace-cmd report display the
name of the buffer at the beginning of each event. Adjust the parsing
regex to ignore it.

FEATURE

Add a file for Pixel 6-specific analysis.
Include methods df_power_meter() for getting power meter readings in mW
and plot_power_meter() for plotting out the meter readings from
different channels.

FEATURE

Add a vdims (value dimensions) parameter to plot_signal.
Additionally, set the unit of the preexisting Time dimension to seconds.

Revert "Merge pull request #1953 from mrkajetanp/gb6"

This reverts commit 2eeca38b, reversing
changes made to 72e4d039.

FEATURE

Report kernel module build error reporting in FtraceCollector: it will
always raise a MissingTraceEventError() along with an error-level log
stating that the module build was attempted because of unavailable
events.

Currently, WAOutput objects can be created by passing a directory
containing multiple different runs, each potentially with many
iterations. Those runs will then be concatenated in the df.

The same functionality can be easily replicated by creating the objects
separately and concatenating their dfs as needed while avoiding
potential issues with mixing different runs inside one object.

Kajetan Puchalski authored Feb 13, 2023 and Douglas Raillard committed Mar 13, 2023

FEATURE

This commit allows acessing a list of jobs in the WAOutput through
wa_output.jobs along with a LazyMapping of raw Trace objects in
WATraceCollector through wa_output['trace'].traces.

It also adds an 'outputs' property to WAOutput through which a dict of
discovered WAOutputs can be accessed.

Alongside that, a private _jobs property is created to unify job
discovery between the old multi-wa-output approach and the new
sigle-output approach.

It modifies the _needs_params method to ignore parameters that are
VAR_POSITIONAL or VAR_KEYWORD. This is so that the
trace collector can be accessed with ['trace'] instead of just through
get_collector() under this use case.

Kajetan Puchalski authored Feb 28, 2023 and Douglas Raillard committed Mar 13, 2023

FEATURE

Add a LazyMapping class to create dict-like objects the elements of
which can be evaluated on the fly.

FIX

Fix typo in the parser detection that made it default to trace.dat
parser when extension is .html.

FIX

Uses the appropriate constructor for HTML trace files.

* Add details on expectations of docstrings.
* State pylint expectations (or lack of).
* Cleanup the self test section.
* Add section on how to update binary tools.
