RTT| 00:00:01 (periodic user-mode task, 100 us period, priority 99) RTH|-----lat min|-----lat avg|-----lat max|-overrun|----lat best|---lat worst RTD| 4.493| 12.861| 25.111| 0| 4.493| 25.111 RTD| 9.057| 13.876| 1152.413| 37| 4.493| 1152.413 RTD| 12.180| 13.755| 640.259| 53| 4.493| 1152.413 RTD| 12.285| 13.924| 618.703| 70| 4.493| 1152.413 ... Please not I use CONFIG_HZ=250 as CONFIG_HZ=1000 freezes at boot time system with "clocksource tsc unstable" message. If I set HPET: CONFIG_HPET_TIMER=y CONFIG_HPET_EMULATE_RTC=y CONFIG_X86_UP_APIC=y CONFIG_X86_UP_IOAPIC=y CONFIG_X86_LOCAL_APIC=y CONFIG_X86_IO_APIC=y I have a very strange message when starting latency: Xenomai: native skin or CONFIG_XENO_OPT_PERVASIVE disabled. (modprobe xeno_native?) Of course native skin is present and CONFIG_XENO_OPT_PERVASIVE enabled CONFIG_XENO_SKIN_NATIVE=y CONFIG_XENO_OPT_PERVASIVE=y Any idea? Thx by advance. -- Pierre FICHEUX -/- CTO OW/OS4I, France -\- pierre.ficheux@domain.hid http://www.os4i.com http://www.ficheux.org I would love to change the world, but they won't give me the source code
