hi, Please find attached latency test result. Iam facing latency problem in my real time application.I have 4 real time task exucting in user space at 10ms & one kernel module task which is executing at 1ms. my application is randomly stuck for 2-3 sec. sometimes greater than this also. simulataneously i run latency test it also shows overruns count more than 200.it is not deterministic behaviour. my current machine has below configuration 1.Ubunbtu-12.04 2.RTAI-4.0 3.kernel 3.5.7 4.Cpu core -Intel Pentium 4. 5.Timer-tsc. 6.No. of core-1. The same applications work deterministic in my older system which has kernel 2.6.23 & rtai-3.9 & centos distro with same PC. Is there any problem with kernel or rtai or ubuntu or kernel configuaration? Please let me know any solution for this problem. -- Thanks & Regards, *Sameer Zungare* +91 9021918228 */iASYS/* *Product Development Center* 401 A/2, Nano Space Baner-Pashan link road, Baner Pune 411045, India Ph. +91 96234 47255 ext. xxx www.iasys.co.in _______________________________________________ Rtai mailing list [email protected] https://mail.rtai.org/cgi-bin/mailman/listinfo/rtai
