Please try the default setting for SMI (only detection), you are supposed to be only try disabling SMIs if you have unexplained latency issues with Xenomai, so, it is premature to enable it while Xenomai is not even starting. > > The difference between the later ones is: > Before, I disabled all ACPI. Now, I just disabled that ones at the FAQ. That is precisely the thing that I found was wrong in your configuration, and I had hope that enabling the ACPI would allow the cpu frequency to be detected correctly. Note that I do not even know how cpu frequency is detected on x86. > CONFIG_CPU_FREQ was disabled. > > So, when I boot the new kernel, the /proc/cpuinfo returns 0.00 of CPU > Frequency again... > > The problem is the error at identifying the processor. > The new /proc/cpuinfo returns only one processor... not the both nucleus, > like that one up here. You mean the two cores? That is probably because you disabled CONFIG_SMP. If CONFIG_SMP is not disabled, please post the full kernel log. What you can try is with exactly the same configuration which fails with Xenomai (if it still fails when not disabling SMIs), is use this same configuration, only disable CONFIG_XENOMAI and CONFIG_IPIPE and tell us whether the frequency is right. NB: on Xenomai mailing lists, we are more used to the traditional usenet way of quoting the relevant part of the mail we answer and answering under, than the MS-outlook style top-posting. -- Gilles.
