[webkit-help] Automatic Layout Test Execution for Cross Compiled Platforms

[Arunprasad Rajkumar]

Dirk, Thank you very much for giving more information.

I understood like, once the completion of build, from host we can trigger
the target device(a remote embedded device) to pick up the compiled DRT &
other relevant files to start layout test. Upon completion of each result
it has to be notified to the host which hosts the buildbot slave. Another
way would be having two buildbot slaves, one for cross compiling the webkit
which runs on host machine(x86_64+Linux) and another would be running on
embedded device(ARM/MIPS/SH4 + Linux) which only runs layout tests. Final
result would be based on these two bots.

I will investigate further about what are all the run-time(perl,python)
need for the things to run. If you found some time, please comment whether
my approach is good or too bad.

Kind Regards,
Arun.
