Dear All,
I am pleased to announce rtnptl-2.3 is out.
Changes from 2.2
================
* The requeue feature of robust condvar has been enabled.
* The relative timeout timespec in timed functions has been replaced
with absolute timeout timespec with the fusyn support.
* The default mutex unlocking mode can be selected automatically by the
fusyn kernel.
* The arch-independent codes in lowlevellock.h have been moved to
lowlevelrtlock.h at upper directory.
* Some bug fixes.
Rtnpl is based on the latest GLIBC and the following Real-time features
have been implemented:
- Robust Mutexes
- Priority Inheritance
- Priority Protection
- Robust Condvar
Currently it works on both x86, ia64 and powerpc.
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/fusyn/INSTALL-rtnptl-upon-fu
syn.
You could find our CVS repository with the following steps:
# To get the latest fusyn codes
$ export CVSROOT=:pserver:cvsanon@developer.osdl.org/repos
$ cvs login #(no password, just hit enter)
$ cvs co -r fusyn___branch robustmutexes/fusyn
# To get the latest rtnptl codes + the latest glibc code
$ cvs co -r rtnptl___branch robustmutexes/rtnptl
You'll need the latest glibc cvs sources, if you'd like to apply the
patch by yourself (NOTE: The parameter "-E" of patch command is required
to remove some empty files.).
All the rtnptl patches can be found at
http://developer.osdl.org/dev/robustmutexes/rtnptl/.
Any feedback, bug reports, and bug fixes are highly appreciated. Thanks.
