Linux Involvement stats

Used internally for BayLibre to meter the linux involvement.

Taken from : https://github.com/gregkh/kernel-history

And added :

• "-a" option to grep into emails to show in the summary
• "-A" option to grep authors in the "git log"
• "-G" option to grep into commit message in the "git log"
• "-T" option to output a CSV table
• "-F" option to handle only emails instead of Full or Short name to avoid duplications

The script linux_stats.sh computes all BayLibre members Linux involvement stats since Linux 2.6.11 :

$ /path/to/linux_stats.sh

And will generate a bunch of stats-v3.10-v3.11.svg, ... available in this baylibre-stats directory.

Optionnally, you can specify a range of tags or branches to speed up the generation :

$ /path/to/linux_stats.sh "v4.10 v4.11"

Examples :

Find all contributions and involvement of BayLibre in Linux 4.10

$ /path/to/gitstat -N -a baylibre -o v4.9..v4.10

Sample output : https://gist.github.com/superna9999/57b58b80b2519b8a0ce0b82b3c4d09f3

Find all contributions and involvement on Amlogic patches in Linux 4.10

$ /path/to/gitstat -G amlogic -G meson -o v4.9..v4.10

Sample output : https://gist.github.com/superna9999/0ea3fedaaf30f0928225f66f8189a031

Show all contributions and involvement on BayLibre only patches in Linux 4.10

$ /path/to/gitstat -N -A baylibre -o v4.9..v4.10

Sample output : https://gist.github.com/superna9999/444ffe6c96555f93b640b2a90baf7f52

Export CSV of contributions and involvement on BayLibre only patches in Linux 4.10

$ /path/to/gitstat -A baylibre -o v4.9..v4.10 -T > out.csv
$ gnuplot /path/to/csv.plot

The gnuplot csv.plot scripts takes the out.csv file as input and outputs a out.svg file.

Here is the corresponding sample :
