hi, to create hard realtime linux programs with freepascal and xenomai [1] in userspace I'm installing a custom ThreadManager and a MemoryMutexManager on program init like this: SetThreadManager( XenoThreadManager ); SetMemoryMutexManager( XenoMemoryMutexManager );
This worked until 2.2.4. With fpc 2.4.0, TMemoryMutexManager was removed with commit "r7407 20.5.2007 + heap manager now per thread, reduce heap lock contention" Looking at rtl/inc/heap.inc from 2.4.0 it seems that the locking is now done using "CriticalSections", is that true ? To adapt my ThreadManager for 2.4.0 I think I have to: - remove the SetMemoryMutexManager() call - implement the *CriticalSection() calls in my XenoThreadManager Has someone any hints, comments or concerns about the approach ? Anyone else interested in building hard realtime programs using fpc and xenomai ? thank you kisda [1] Xenomai Real-Time Framework for Linux - www.xenomai.org
