[Xenomai-core] [PATCH] SMI-doc improvement / RTDM paper
Hi Philippe, this patch tries to clarify where to solve SMI-related latencies. Or should we even mention the kconfig path? Moreover, I would like to upload my RTL-Workshop paper about RTDM to doc/nodist/pdf (~150k) so that it later makes it on the website as well. Ok?

Hi all! Jan Kiszka wrote: [...] +printk(Xenomai: Intel chipset found but SMI workaround not enabled in kernel\n +configuration. You may encounter high interrupt latencies.\n); Speaking of printk. Since 2.1 I don't see any messages in the kernel log. I bet there is a new switch somewhere, but I can't find it. Any hint appreciated. BTW, Jan, the SMI seems to be disabled now, even if I haven't seen the message of disabling SMI in the klog. Thanks best regards, Hannes. ___ Xenomai-core mailing list Xenomai-core@gna.org https://mail.gna.org/listinfo/xenomai-core

I forgot that as of 2.1 everything is compiled into the kernel by default, so when running a testsuite example there are no messages that xeno is loaded or unloaded. Thanks and best regards, Hannes.
