[Xenomai] Power management frame work in RTDM xenomai

[JAY KOTHARI]

Hello,
        I am using power management frame work with RTDM. If my
process is in suspended state and am requesting irq in RTDM or open
call from rt_dev_open then will it resume the device????
My user api rt_dev_open is unable to find the RTDM for it. Is there
any other approach of power management in RTDM???

Thank you

Jay Kothari

There is absolutely no support for PM in Xenomai, including with RTDM.

Yes, because there is no need, at least for typical use cases (like this
one). Just invoke the related Linux service calls during device
activation like a normal Linux driver would do. That's fine as the
device is opened in Linux context.
