Subject: [Xenomai] Linux scheduling is hijacked from xenomai scheduling
Date: Tue, 27 Jan 2015 10:56:12 +0100 [thread overview]
Message-ID: <54C760BC.7040301@colgp.it> (raw)
Hi to all,
we are using kernel 2.6.34 with the corresponding ADEOS patch
(2.6.34-powerpc-2.10-03.patch ) and Xenomai on a PowerPC MPC5200b.
We are facing on a strange behavior when mixing Linux SysCalls with
Xenomai tasks . The effect of the above mix is that the "pure" (without
linux syscall) xenomai task continues to run , the remaining "mixed"
task (for example we have one with a posix socket server) and moreover
the linux os itself are not scheduled anymore. Specifically, to test
this behavior, we connected an oscilloscope to a cpu pin , the result is
that the xenomai task is moving the pin up and down (as it was
programmed) but the linux machine is neither accessible via ping or via SSH.
Do you have some suggestions, or some tests we can do ?
Thanks
Regards
