To: xenomai
I have successfully got xenomai 3.0.3 running on the Freescale/NXP
4.1.15-2.0.0 kernel. Using Mesa graphics I was able too run the xeno-test
-l dohell and other tests.
When I reconfigured the system to use the native graphics (galcore.ko
kernel module) and EGLS2.0, get a kernel bug. I was wondering if anyone had
experience with using the imx6q with the native GPU and Xenomai?
I am sure the galcore.ko kernel module is not playing nice with xenomai. It
is built separately and has no patches in it. Below is the kernel trace as
well as some of the spam messages coming out afterwards.
Thanks for you time,
Jackson Jones

To: Jackson Jones; +Cc: xenomai
Dear Jackson,
I have the same problem in i.mx6q (Linux 3.14.38 + xenomai 2.6.5).
Crash message appears at the same part when using the xenomai api in a Qt5
application.
I had debugging a GPU driver.
GPU driver had too much virtual memory and physical memory mapping and
memory allocation.
I think this was the main cause of the GPU driver crash with xenomai.
I agree your opinion that with xenomai and galcore module does not work
fine.
I attach the my crash message (as below).
Regards, Daesik Kwak
