Subject: [Xenomai] GPIO in Xenomai

Message-ID: <50B5B966.4080506@gmail.com> (raw)

Hi,

I'm looking for a way to use the SoC GPIO's (MPC5200) in an RT thread.
Accessing them via the sysfs (the Linux userspace way) is not an option
since we need to access the GPIO's at a quite high frequency.

How could the Linux gpiolib infrastructure best be exposed to RT
threads? Has this been discussed before? Any ideas about the "best"
approach here?

Thanks,
Stefan
