Hi Philippe=20
=20
Based on RTSJ (www.rtj.org) proposal, I have recently modified Kaffe for =
real-time applications. The previous implementation has created a =
javax.realtime package and modified the Kaffe VM for real-time purpose =
(jthread) under Linux. The modification of Kaffe VM includes the =
priority inheritance protocol, management of RealtimeThread and =
PeriodicThread, and other modifications.=20
=20
In fact, the previous version was missing the memory modifications and =
some other classes of the RTSJ specification. I also simplified the =
creation of javax.realtime package into Klasses.jar (Klasses.jar =3D =
java.lang.* + javax.realtime.*). =20
Now, Cris is going to complete some lacking parts of my previous =
implementation and separate the javax.realtime package from Klasses.jar. =
Could you please tell us your current achievement of pthreads porting =
for Real-time applications ? When will the ptherad real-time of Kaffe =
be merged into traditional Open Kaffe VM ?=20
Regards,
Erik
