Hello Avi, thank you for chiming in. Neither iomem runtime parameter or allowing mmap on 0 page helped me. As for the latter, DPDK correctly maps to PCI region, so that is not the problem. Looking at the mmap source, there are basically only two points that result in EPERM error. First one is related to incorrect flag combination (not a DPDK case) the second is related to the file descriptor of the resource being locked (should not be, but it is the only possibility). That lock may have to do something with Secure boot being on, as almost the same system without secure boot is working ok. I built a custom kernel with CONFIG_STRICT_DEVMEM turned off, but it's going to take me some time to hammer it into the system, mainly because I am leaving for a vacation today. But it would be great if anyone, who has experience running DPDK on secure booted systems, could share their experience. Cheers, Martin
