lkstat is simple tool to figure out where Linaro has maintainer in Linux kernel and it will also give an indication of the activitiy in the different subsystems. The tool will generate "mindmap" trees that can be imported by a tool called Freeplane.

There are a couple of different parameters to tweak the query.

usage: lkstat.py [-h] [--disable-altname] [--assignee] [-a] [-p PATH]
                 [-s SINCE] [-o OUTPUT] [-v]

Script used to generate Freeplane mindmap files

optional arguments:
  -h, --help            show this help message and exit
  --disable-altname     Use alternative names (from cfg.yaml) to the tree
  --assignee            Add assignees (from cfg.yaml) to the tree
  -a, --author          If set, git statistic only count the commit from the
                        author
  -p PATH, --path PATH  Full path to the kernel tree
  -s SINCE, --since SINCE
                        Used with the git log --since command
  -o OUTPUT, --output OUTPUT
                        Output filename
  -v                    Output some verbose debugging info

$ git clone https://github.com/jbech-linaro/lkstat.git
$ pip install -r requirements.txt

The script by default look at the script authors kernel tree (hardcoded), hence other users of lkstat must at least use the -p parameter to give the absolute path to a kernel tree that is up-to-date. Then by calling just the script, it will:

• find all Linaro maintainers and also the ones who aren't using their Linaro email address (see cfg.yaml).
• not include assignees (again see cfg.yaml).
• look a year back from todays date.
• show activity based on all patches in that subsystem. I.e., not only the ones from the maintainer itself (see Maintainer activity below for more information regarding that).

First ensure that the cfg cfg.yaml contains the correct information. Then after that run the script as usual, but also append the --assignee parameter. Now, the mindmap tree will contain the assignees as well.

If you want to generate a graph to get an idea of the contributions from the maintainer itself in the subsystem, then you should append -a as a parameter when running the script.

Note! The script is currently unable to gather correct statics is there are more than a single Linaro maintainer for a subsystem. To avoid confusion, subsystems is colored in blue and overstike when there are more than one Linaro maintainer (i.e., result isn't usable).

By default lkstat looks a year back. If you want to check another period, then you can do that by providing a -s yyyy-nn-dd parameter.

With the -o another-name.mm parameter you tell lkstat to create a mindmap tree with another filename than the default linux-kernel.mm.

The nodes in the mindmap tree have different colors.

• Green: indicates more than a patch per week.
• Orange: indicates more than a patch per month.
• Red: Less than a patch per month.
• Blue: More than a single Maintainer, node statistic information isn't usable.
• Grey: File in MAINTAINERS doesn't actually exist (patch should be sent to LKML to fix it).
