PR2 indigo kernel with RT_PREEMPT

[Shingo Kitagawa]

Hi everyone,

I'm Shingo Kitagawa at JSK Lab, the University of Tokyo.

I want to know the information about the PR2 indigo kernel with RT_PREEMPT patch.

pr2-kernel is now linux-image-3.19.0-49-lowlatency, but PR2 c1 uses RT_PREEMPT patched kernel in the previous distro.

Does anyone use the RT_PREEMPT kernel in PR2 with ROS indigo?

Or does anyone compare the performance between lowlatency and RT_PREEMPT kernel in PR2?

We want information about this for the further PR2 upgrade.

Thank you.
