Preempt-RT on OMAP3?

Hi everyone,

I'm trying to get the realtime patch set to work on OMAP3 (Gumstix
Overo). Linux-omap 2.6.29 with the RT patches -rt1 or -rt2 work mostly
as is (MUSB and the usb-gadget layer have quite a few problems, and
the realtime self-test stuff picks up a few problems to do with
spinlock usage etc, but most things seem to mostly work correctly for
my needs). Running cyclictest with various types of loads gives an
average latency of ~30-50 usec and worst case up around 300 usec.

Is anyone working on RT on omap3? Is there a more suitable mailing
list for this? Is there a git repo somewhere tracking the work on
2.6.39-rtX for OMAP?

Thanks,
Hugo Vincent
