[cgl_discussion] [RFC/PATCH] RT-NPTL-2.0

[Hu, Boris]

Dear All,

I am pleased to announce rtnptl-2.0 is out. 

Rtnpl-2.0 is based on the latest NPTL(Native POSIX Thread Library) (http://people.redhat.com/drepper/nptl-design.pdf) and the following Realtime features have been added: 
   - Robust Mutex
   - Priority Inheritance
   - Priority Protection
   - Robust Condvar
* The macro USE_FUSYN_ROBUST_MUTEX is used to enable or disable the RT feathers. 

Currently it works on both x86 and ia64.
 
It is required FUSYN(Fast User SYNChronization) kernel:
http://developer.osdl.org/dev/robustmutexes/fusyn/.

The installation manual can be found at: 
http://developer.osdl.org/dev/robustmutexes/rtnptl/.

You'll need the glibc cvs sources.  Use them as of
2003-11-22 02:27.

All the rtnptl patches can be found at http://developer.osdl.org/dev/robustmutexes/rtnptl/.
