When binding the devices used by DPDK to the "uio-pci" kernel module,
the IOMMU should be disabled in order not to break the IO transmission
because of the virtual / physical address mapping.
The patch clarifies the IOMMU configuration on both x86_64 and arm64
systems.

Without any specific Rx offload flag, default behavior by PMDs is to
strip CRC.
PMDs that support keeping CRC should advertise DEV_RX_OFFLOAD_KEEP_CRC

Now that we can retrieve page fd's internally, we can expose it
as an external API. This will add two flavors of API - thread-safe
and non-thread-safe. Fix up internal API's to return values we need

This patchset further improves DPDK support for running
without hugetlbfs mountpoints.
First of all, it enables using memfd-created hugepages in
in-memory mode. This way, instead of anonymous hugepages, we
can get proper fd's for each page (or for the entire segment,

Enable setting and retrieving segment fd's internally.
For now, retrieving fd's will not be used anywhere until we
get an external API, but it will be useful for things like
virtio, where we wish to share segment fd's.
Setting segment fd's will not be available as a public API
at this time, but i

Previously, we were only tracking lock file fd's in single-file
segments mode, but did not track fd's in non-single file mode
because we didn't need to (mmap() call still kept the lock). Now

Enable using memfd-created segments if supported by the system.
This will allow having real fd's for pages but without hugetlbfs
mounts, which will enable in-memory mode to be used with virtio.
The implementation is mostly piggy-backing on existing real-fd
code, except that we no longer need to u
Previously, when we allocated hugepages, we closed the fd's corresponding
to them after we've done our mappings. Since we did mmap(), we didn't
actually lose the reference, but file descriptors used for mmap() do not
count against the fd limit. Since we are going to store all of our fd's,
we will h
In-memory mode was never meant to support legacy mode, because we
cannot sort anonymous pages anyway.

In a few cases, user may need to query offset into fd for a
particular memory segment (for example, to selectively map

This commit adds rte_table_hash_func.h and rte_table_hash_func_arm64.h to
librte_table. This will replace hash_func.h and hash_func_arm64.h in the IP

As we are now using the new header files, we can remove the old ones from

Thanks for the patch.
Do we need both of the state and istate struct? struct rte_hash_iterator_state
seems not doing much.
How about we only have one "state" struct and just not expose the internals to
the public API, similar to the
rte_hash struct or rte_member_setsum struct.
And in _init fun
Hmm, I guess my comment is for code readability. If we don’t need the extra
state that would be great.
I think "rte_hash" is defined as an internal data structure but expose the type
to the public header. Would this work?
I propose to malloc inside function mostly because I think it is cleaner
Hi Tone,
>if the devices for used DPDK bound to the ``uio-pci`` kernel module,
please make
The three kernel modules which can be used for DPDK binding are vfio-pci,
uio_pci_generic and igb_uio. Don't you mean here uio_pci_generic ?
