-Xen Dom0 support without hugetbls
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The existing memory management implementation is based on the Linux kernel hugepage mechanism.
-However, Xen Dom0 does not support hugepages, so a new Linux kernel module rte_dom0_mm is added to workaround this limitation.
-
-The EAL uses IOCTL interface to notify the Linux kernel module rte_dom0_mm to allocate memory of specified size,
-and get all memory segments information from the module,
-and the EAL uses MMAP interface to map the allocated memory.
-For each memory segment, the physical addresses are contiguous within it but actual hardware addresses are contiguous within 2MB.
