Do you get a bug with I-pipe alone ? Or with Xenomai ? If with Xenomai, you should probably change Xenomai context switch routine to match Linux context switch routine (adding a call to set_pid, if I understood your patch correctly). > > Anyhow, perhaps the ARM people might take a look at combining > ipipe with FCSE... I hope that others can test it: the machine with which I work at home is an AT91RM9200, without FCSE support, and the IXP465 I have at work runs more than 96 pids. There is something I did not understand in your patch: do you reserve PIDs for shared libraries ? How do you handle threads stacks ? The old FASS patch had problems with this. Also, it is completely unrelated, did you see the recent post about write buffer coalescence on the Linux arm kernel mailing list ? From my test on IXP465 it seems that these machines are affected as well. -- Gilles Chanteperdrix _______________________________________________ Adeos-main mailing list [email protected] https://mail.gna.org/listinfo/adeos-main
