I configured the 82599 ports to work in multi-queue mode and flow director to
assign different TCP connections to different queues. A multi-process
application receive packets from queues and each?process reads a queue. When I

By the way, the?pci_map_resource will check the mapaddr ==?requested_addr. So
you must provide a usable?requested_addr. It's a reason I modified
the?pci_map_resource().--From:??

It is a default value when the requested_addr isn't exist, not an overide. When
the?pci_map_resource is called at the primary process, the?requested_addr is
NULL. The default value will be provided by?default_map_addr.
When the?pci_map_resource is called at the secondery process,

Ah, yes, sorry about that, haven?t quite woke up yet
L You?re right. So it?s removing the dependency on --base-virtaddr, moving the
function to eal_pci.c
?and adding similar VFIO code that?s left then.

How to find the?maximum end virtual address ??I'm not the DPDK expert, but I
will try to do my best.
If the segments isn't overlap, "if(seg->addr > last->addr)?last = seg;"
already find the segment with?maximum end virtual address.

When start a secondary process, we got error message "EAL: pci_map_resource():
cannot mmap(11, 0x77fba000, 0x2, 0x0): Bad file descriptor
(0x77fb9000)"
The secondary process link difference shared libraries, so the 0x77fba000
is used.
We know the --base_virtaddr is designed f
