Subject: [dpdk-dev] [PATCH v2 0/3] ethdev: configure SR-IOV VF from host
Date: Tue, 29 Oct 2019 19:50:48 +0100 [thread overview]
Message-ID: <20191029185051.32203-1-thomas@monjalon.net> (raw)
In-Reply-To: <4165509.5enYigmRGf@xps>
In a virtual environment, the network controller may have to configure
some SR-IOV VF parameters for security reasons.
When the PF (host port) is driven by DPDK (OVS-DPDK case),
we face two different cases:
- driver is bifurcated (Mellanox case),
so the VF can be configured via the kernel.
- driver is on top of UIO or VFIO, so DPDK API is required,
and PMD-specific APIs were used.
This new generic API will avoid vendors fragmentation.
Some PMD-specific API could migrate to this generic model.
As an example, the default MAC address configuration is demonstrated
for a VF mapped to mlx5 representor port.
As it breaks the ABI, I propose to merge this API in DPDK 19.11-rc2.
I am sorry I had not send a patch since proposing a RFC in August.
(I gave priority to the summit and the -rc1 release)
Thomas Monjalon (3):
ethdev: identify SR-IOV VF from host
ethdev: set VF MAC address from host
net/mlx5: set VF MAC address from host
