Bug ID: 1221
Summary: PPC64le memory init use mmap return EBUSY
Product: DPDK
Version: 21.11
Hardware: POWER
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: core
Assignee: dev@dpdk.org
Reporter: haibowu@hcdatainc.com
Target Milestone: ---
When dpdk is initializing, it will first use the eal_get_virtual_area() to
obtain the virtual address(pagesize is 64K), and then call the mmap() to bind
the hugepage(pagesize is 16M) to the corresponding virtual address, but because
the pagesize is different, it will report EBUSY in PPC64. Maybe we need use
MAP_HUGETLB in the mmap parameters of eal_get_virtual_area().
