Hey there,
I noticed a spike in the latency over around 600-800microseconds when
starting an opengl window.
I have the SMI workaround enabled and also included my device id in the
/usr/src/xenomai/ksrc/arch/x86/smi.c
file
lspci -vvv -nn shows a
Intel Corporation 82801JIR (ICH10R) LPC Interface Controller [8086:3a16]
so I added
{PCI_DEVICE(PCI_VENDOR_ID_INTEL, PCI_DEVICE_ID_INTEL_ICH10_1)},
After recompiling the kernel I finally saw
[ 2.443949] Xenomai: SMI-enabled chipset found
( I did not see that line before )
but unfortunately I also saw
[ 2.443957] Xenomai: SMI workaround failed!
Well, the latency test still showed spikes of about 600-800microsends when
for example starting or closing glxgears. I am using a nvidia FxQuadro FX
4800 and I am using the latest nvidia driver which I downloaded from the
nvidia homepage (256.53).
I am running
Linux xeno_machine 2.6.31.4-ipipe #1 SMP Thu Oct 7 18:13:54 PDT 2010 x86_64
GNU/Linux
and Xenomai version is 2.5.2
Thanks for any help,
Peter
