When start a secondary process, we got error message "EAL: pci_map_resource(): cannot mmap(11, 0x7ffff7fba000, 0x20000, 0x0): Bad file descriptor (0x7ffff7fb9000)"
The secondary process link difference shared libraries, so the 0x7ffff7fba000 is used.
We know the --base_virtaddr is designed for this situation for hugepages.
This patch map the device resouce into address that is after hugepages when --base_virtaddr is configured.
