Hi,
Im working on an iMX6 based board with NXP kernel 4.1.15.
I would like to understand why latency max returned by cyclictest
increases from 20µs to 100µs when dohell accesses to USB.
Since i-pipe tracer refuses to work, I used ftrace to record cobalt,
scheduling and irq events. Here is what
Hi,
Im working on an iMX6 based board with NXP kernel 4.1.15.
Using cyclictest and dohell, I benched latency on my Xenomai + Preempt-rt
kernel. To understand the results, I wanted to activate ftrace and
ipipe-tracer.
While ftrace activation was not a big deal, when "I-pipe debugging" is
Hi Philippe,
Thank's for your answere.
Replacing spin lock calls by equivalent raw spin lock in gpio_generic did
the trick.
Thank's a lot.

Hi,
Im working on an iMX6 based board with NXP kernel 4.1.15.
I made a Xenomai 3.0.5/ipipe bsp that works well and I also made a
preempt-rt bsp that works well too.
However, now I would like to make a Xenomai/ipipe + preempt_rt bsp.
I adapted preempt_rt patch to fit to ipipe patched

xenomai nor ipipe logs into kernel boot logs, and no /proc/xenomai at all.
I must have missed something or doing something wrong, but I dont see.

now a correct training center for this ?
=> Is there anyone experienced in Xenomai on i.MX6 (tricks, classical
traps
) ?
