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 bi=
nd
the hugepage(pagesize is 16M) to the corresponding virtual address, but bec=
ause
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().
