Gilles Chanteperdrix wrote: Richard Cochran wrote: I have been trying to bring my IXP425 based system up to date, and I have found an apparent regression. Everything worked fine with ipipe 2.6.30 and Xenomai 2.4. With 2.6.31 an ipipe kernel still boots, but starting with 2.6.33 the trouble begins (see below). I see that Gilles refactored the TSC emulation starting with 2.6.33. I wonder whether this could be the cause? What this modification does is that: - there is only one clocksource, which is now xenomai tsc, with a very high rating; - the tsc read code is written in assembly, and copied in the vectors page, the one at 0x. I think the ixp is a 32 bits free-running counter with match register, wich is a configuration I tested. So, I would tend to think that the issue is rather in the clock_events implementation. Just to explain a little further about this modification. The reasons for this refactoring are: - the TSC emulation code is factored, so that when porting to a new port, we avoid copy-pasting the TSC emulation; - it is written in assembly, because even for such a simple thing, I was unable to get gcc to generate optimal code without useless register moves; - it is ready for multi-SOCs kernels (all the TSC emulations are compiled-in, the one chosen is copied to the vectors page when the ipipe_tsc_register function is called). This is the direction ARM linux is going, if you followed the ARM wrestling on the linux-arm-kernel mailing list. - the Linux clocksource code also uses this TSC, this keeps it in cache, and gets us ready for hostrt (actually, hostrt is already there on ARM, what is missing is just the equivalent of the code that was sent to the ARM mailing list for x86_32). - and most of all, this implementation is in the vector page, so is available to user-space applications. This means that Xenomai user-space support can be compiled without any knowledge of the actual TSC involved. IOW, it means that Xenomai user-space support compiled with --enable-arm-mach=generic (which is going to be the default) can use TSC emulation.. -- Gilles. ___ Xenomai-core mailing list Xenomai-core@gna.org https://mail.gna.org/listinfo/xenomai-core

[Xenomai-core] kernel threads crash
Hi I'm trying to implement some gateway functionality in the kernel on a emerson CPCI6200 board, but have run into some strange errors. The kernel module is made up of two threads that run every 1 ms. I have also made use of the rtpc dispatcher in rtnet to dispatch control messages from a netlink socket to the RT part of my kernel module. The problem is that when loaded the threads get suspended due to exceptions: Xenomai: suspending kernel thread b929cbc0 ('tt_upgw_0') at 0xb929cbc0 after exception #1792 or Xenomai: suspending kernel thread b929cbc0 ('tt_upgw_0') at 0x0 after exception #1025 or Xenomai: suspending kernel thread b911f518 ('rtnet-rtpc') at 0xb911f940 after exception #1792 I have ported the gianfar driver from linux to rtnet. The versions and hardware are listed below. The errors are most likely due to faulty software on my part, but i would like to ask if there are any known issues with the versions or hardware i'm using. I would also like to ask if there are any ways of further debugging the errors as i am not getting very far with the above messages.
