Resent, because it bounced the first time. ---------- Forwarded message ---------- From: John Candlish <[email protected]> Date: Tue, May 28, 2013 at 9:08 PM Subject: SMI problems with 2.6.2.1 and last weekends git version To: [email protected]
Hello This was originally about linuxCNC, but was reminded to post my SMI findings here. from the emc-developers list: http://thread.gmane.org/gmane.linux.distributions.emc.devel/9863 <quote> What I found out about RTAI and Xenomai? Xenomai 2.6.2.1 stable or GIT do not handle SMI masking correctly for my ICH7 chipsets. In the case of the stable download the chipset is detected but the SMI workaround fails to apply. --- May 25 07:42:05 sixis kernel: Xenomai: real-time nucleus v2.6.2.1 (Day At The Beach) loaded. May 25 07:42:05 sixis kernel: Xenomai: debug mode enabled. May 25 07:42:05 sixis kernel: Xenomai: SMI-enabled chipset found May 25 07:42:05 sixis kernel: Xenomai: SMI workaround failed! --- In the case of the GIT version the kernel command line parameter 'xeno_hal.smi=1' is not respected. --- May 26 08:31:48 sixis kernel: Xenomai: real-time nucleus v2.6.2.1 (Day At The Beach) loaded. May 26 08:31:48 sixis kernel: Xenomai: debug mode enabled. May 26 08:31:48 sixis kernel: Xenomai: SMI-enabled chipset found, but SMI workaround disabled May 26 08:31:48 sixis kernel: (see xeno_hal.smi parameter). You may encounter May 26 08:31:48 sixis kernel: high interrupt latencies! --- I was seeing latency as high as 100us with Xenomai, so it is currently not working for me. </quote> This is on a Dell gx620, Pentium D 820, ICH7 chipset machine. I could do more testing if it is a help. I would very much like to get Xenomai working for me, but both the stable version or the git version have SMI problems. Thanksyou jCandlish . _______________________________________________ Xenomai mailing list [email protected] http://www.xenomai.org/mailman/listinfo/xenomai
