Hi,
I'm observing high latencies when running the latency test on a
Core2Duo. They appear sporadically and are mostly between 100 and 300
us. Sometimes they are about 800 us. I have attached two I-pipe trace
outputs.
Kernel is 2.6.25, Xenomai is 2.4.4, I-pipe is 2.0-08. ACPI, APM and CPU
frequency scaling are all of, SMI workaround is enabled.
Any idea anyone?

Enable ACPI, only disable ACPI processor module. Enable USB. You
should also look in the kernel log if the SMI workaround actually
worked or not.

OK.

OK. Additionally, legacy USB support was disabled in the BIOS.

Thanks. Is the latency spot regularly happening at the same place after a few runs,
or rather randomly?

I can for sure activate it with a kernel compilation with make -j2.
Without load, it is more or less random and more seldom.

I have the same problem. The chipset is Q35 (ICH9). I have add a line in
smi.c
{PCI_DEVICE(PCI_VENDOR_ID_INTEL, PCI_DEVICE_ID_INTEL_ICH9_4)}
This line can enable the SMI (can be verified by dmesg). But high latency
still can be found, in my case, latency always happens in default_idle. See
the attached i-pipe tracer data.

Could you try booting with idle=poll just to make sure that we don't get trapped
into long wakeup latency from some idling instruction? We explicitly avoid mwait
unless forced to use it by a bootparam, but maybe something goes wrong with the
default idle code as well.
FYI, I have latency spots of the same magnitude on a Dell precision m65 laptop
here too, but I also have latency figures < 5 us under extreme load on a
four-way Opteron-based workstation (Fujitsu Siemens) with the very same
pipeline+Xenomai combo, so there is a significant risk that a hw issue (possibly
chipset) bites us here.
TIA,

Philippe.

Maybe the chipsets evolved and our SMI disabling code is no longer
working... Someone probably needs to read a recent chipset documentation.

Attached is a new trace, I've booted with idle=poll. The latency spots
are still there. Maybe Gilles is right and the SMI disabling code needs
an adaption to new chipsets.
