In drivers/net/virtio/virtio_ethdev.c, I see that that drv_flags is set to

done. Is the value set to 0 to avoid mapping two times?

This patch adds multi-process support for testpmd.
The test cmd example as follows:
the primary cmd:
./testpmd -w xxx --file-prefix=xx -l 0-1 -n 2 -- -i\
--rxq=16 --txq=16 --num-procs=2 --proc-id=0
the secondary cmd:
./testpmd -w xxx --file-prefix=xx -l 2-3 -n 2 -- -i\
--rxq=16 --txq=16 --num-procs
This patch fixes an overhead met with mlx5-vdpa Kernel
driver, where for every page in the mapped area, all the
memory tables gets updated. For example, with 2MB hugepages,
a single IOTLB_UPDATE for a 1GB region causes 512 memory
updates on mlx5-vdpa side.
Using batching mode, the mlx5 driver will
This patch adds missing backend features negotiation for
in Vhost-vDPA. Without it, IOTLB messages v2 could be sent
by Virtio-user PMD while not supported by the backend.

Vhost-vDPA support in Virtio-user PMD was lacking
backend features negotiation and IOTLB batching
support, causing intialization issues with Mellanox
vDPA device managed by Kernel vDPA framework.
Changes in v3:
=
- Fix protocol features negotiation condition (Chenbo)
- Fixup comment in
An example application shows how to use opae ifpga APIs.
You can test each API by running corresponding command.
A guide is also added to show how to run the example.

Cyborg is part of OpenStack, it needs some OPAE type APIs to manage
PACs (Programmable Acceleration Card) with Intel FPGA. Below major
functions are added to meets Cyborg requirements.
1. opae_init_eal() set up EAL environment.
2. opae_cleanup_eal() clean up EAL environment.
3. opae_enumerate() sea
There are three types of property can be got from FPGA, they are
implemented in below functions:
1. ifpga_rawdev_get_fme_property() get property of FME (FPGA
Management Engine).
2. ifpga_rawdev_get_port_property() get property of FPGA port.
3. ifpga_rawdev_get_bmc_property() get property of BMC
RSU (Remote System Update) depends on secure manager which may be
different on various implementations, so a new secure manager device
is implemented for adapting such difference.
There are three major functions added:
1. ifpga_rawdev_update_flash() updates flash with specific image file.
2. ifpga_
Cyborg is part of OpenStack, it needs some OPAE APIs to manage
devices with Intel FPGA. The first three patches implement extra
APIs to meet Cyborg requirement. The last patch add an example
to show how to use these APIs.
Main changes from v7:
- Add guide document for how to run ifpga example
