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 kernel but during
compilation Im facing issues concerning spinlocks:
drivers/gpio/gpio-generic.c:496:2: note: in expansion of macro
'spin_lock_init'
spin_lock_init(&bgc->lock);
^
include/linux/spinlock_rt.h:17:24: error: '__ipipe_spinlock_t {aka struct
<anonymous>}' has no member named 'lock'
rt_mutex_init(&(slock)->lock); \
Searching some help on internet, I realized that only a few people tried
to use both Xenomai and Preempt-rt.
=> Is it an heresy ? if so, Why ?
I thought it was the best way to limit preemption for the tasks that
switched temporarily to secondary mode.
=> If it is not a stupid idea, did somebody already resolve this kind of
conflict ? and how ?
Regards,
Cédric.
