Dear All;I've recently come to notice that the real-time performance of Linux kernel is incredibly improving (against my expectations).http://www.osadl.org/Single-View.111+M5b96e97f67b.0.htmlI'd like to know if the implementation of OSD-library is implemented in such a manner that the kernel-level threads can reflect the priority given by the user to the scheduling of epicsThreads?In other words, can I benefit from the improvement of Linux kernel without making any changes in EPICS source codes?
in file base/configure/CONFIG_SITE change USE_POSIX_THREAD_PRIORITY_SCHEDULING = NO to USE_POSIX_THREAD_PRIORITY_SCHEDULING = YES Also you must start the IOC as root. Marty
