ARM is supporting maximum 4 hugepage sizes (64K, 2M, 32M and 1G) when granule is 4KB since very long and DPDK support maximum 3 hugepage sizes. With all 4 hugepage sizes enabled, applications and some stacks like VPP which are working over DPDK and using "in-memory" eal option, or using separate mount points on ARM based platform, fails at huge page initialization, reporting error messages from eal: EAL: FATAL: Cannot get hugepage information. EAL: Cannot get hugepage information. EAL: Error - exiting with code: 1 This issue is originated from Linux 5.0 (a21b0b78eaf7 "arm64: hugetlb: Register hugepages during arch init") where kernel is by default creating directories for each supported hugepage size in /sys/kernel/mm/hugepages/ On earlier Stable Kernel LTR's, the directories visible in /sys/kernel/mm/hugepages/ were dependent upon what hugepage sizes are configured at boot time. This change increases the maximum supported hugepage sizes to 4 for ARM based platforms.
