1) go to your xeno-patched kernel tree 2) make menuconfig 3) navigate to Real-time sub-system ---> Drivers ---> Testing Drivers 4) enable 'Timer benchmark driver' 5) a new options pops up: 'Kernel-only latency measurement module' 6) enable this option 7) rebuild kernel & install kernel & reboot 8) try again, if you enabled it as a module (M) and not built-in (*) use modprobe to load to module kisda > The dmesg | grep Xenomai gave the following output: > [ 4.353912] I-pipe: Domain Xenomai registered. > [ 4.353949] Xenomai: hal/i386 started. > [ 4.354530] Xenomai: real-time nucleus v2.4.8 (Lords Of Karma) > loaded. > [ 4.354612] Xenomai: SMI-enabled chipset found > [ 4.354623] Xenomai: SMI workaround enabled > [ 4.354647] Xenomai: starting native API services. > [ 4.354650] Xenomai: starting POSIX services. > [ 4.354693] Xenomai: starting RTDM services. > > > > Thanks in advance > > > ------------------------------------- > Hi-Tech Gears Limited, Gurgaon, India > > > > > > _______________________________________________ > Xenomai-core mailing list > Xenomai-core@gna.org > https://mail.gna.org/listinfo/xenomai-core >
