After the below things happened I added a regular user (nitin) to the allowed_group parameter file in /sys/module/xenomai/parameters/allowed_group
Then executed the latency test to get this message : nitin@intel-corei7-64:/usr/bin$ /usr/xenomai/bin/latency 0"000.000| WARNING: [main] cannot open RTDM device /dev/rtdm/memdev-private: Permission denied 0"000.000| WARNING: [main] cannot map private umm area: Permission denied 0"000.000| BUG in init_bind(): [main] (CONFIG_DEVTMPFS_MOUNT not enabled?) ?I must be doing something wrong. Please let me know. - Nitin ________________________________ From: Nitin Kulkarni Sent: Saturday, March 4, 2017 4:26 AM To: [email protected] Subject: Latency test fails after in a Xenomai patched Ostro XT linux distro Hi, I have patched the Xenomai 3.0.3 to an Ostro XT linux distribution and after flashing the image and booting on the Intel Joule board I installed the Xenomai libraries natively. When I run the Latency test it gives this message and stops. root@intel-corei7-64:~/Xenlib# /usr/xenomai/bin/latency == Sampling period: 100 us == Test mode: periodic user-mode task == All results in microseconds /usr/xenomai/bin/latency: pthread_create(latency): Operation not permitted Although I am running as a root user it gives this error. I have not added any user group through the Kernel command line parameter xenomai.allowed_group?. when I run the command dmesg | grep -i xenomai I get this from the Kernel log [ 0.000000] Command line: rootwait console=tty0 xenomai.sysheap_size=256 xenomai.state=enabled xenomai.smi=detect xenomai.smi_mask=1 console=ttyS2,115200 video=efifb maxcpus=4 noxsave reboot=efi kmemleak=off fsck.mode=skip no-ima ro root=PARTUUID=12345678-9abc-def0-0fed-cba987654321 rootfstype=ext4 installer [ 0.000000] Kernel command line: rootwait console=tty0 xenomai.sysheap_size=256 xenomai.state=enabled xenomai.smi=detect xenomai.smi_mask=1 console=ttyS2,115200 video=efifb maxcpus=4 noxsave reboot=efi kmemleak=off fsck.mode=skip no-ima ro root=PARTUUID=12345678-9abc-def0-0fed-cba987654321 rootfstype=ext4 installer [ 0.668993] [Xenomai] scheduling class idle registered.
