Hello, In reviewing the documentation for the PREEMPT_RT patch, it's made pretty clear that performing file I/O (or page faults in general) will degrade realtime performance. The "HOWTO: Build an RT-application" on the wiki also states that page faults from one application will not interfere with the realtime performance of an application. Based on this understanding, if a system utilizing the PREEMPT_RT patch had requirements to perform file I/O, would it be required to have a separate non-realtime process that performs this task or would it be possible to use a low priority thread in the realtime process?
