Dear RT users, I am working on a simulation system. This system uses several simulation modules for generating of video, navigation, motion, digital and analog signals. The data must be generated deterministically to assert proper synchronization with peripherals. These external instruments are accessed via PCI HSD interface. This is outdated technology but it must be used, because this is what these specialized instruments use and replacing the link is not the case, this must be HSD. I have driver for PCIHSD but for 2.4 - 2.6 kernels, this must be ported. It is said that simulation software would ideally run on Ubuntu and motherboard with Intel Core i7-6700 is proposed (very likely with SSD and DDR 4 RAM). I have patched recent version of Ubuntu - Ubuntu 16.04 LTS with recent rt preempt patch patch-4.4.27-rt37 and I can boot to new kernel. In the next step I will measure the worst case latency using cyclictest utility and I will check overall system's performance. Results will be reported. What is your experience with Ubuntu (16.04) and rt preempt. What is your experience with rt preempt and Intel Core i7-6700? Is there any definite "no" for Ubuntu as a real-time operating system? Would it be better to start from Debian? I would appreciate if you could share related information. cheers, Piotr -- To unsubscribe from this list: send the line "unsubscribe linux-rt-users" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
