Greetings,
Following patches are intended to support SR-IOV capability in the
Linux kernel. With these patches, people can turn a PCI device with
the capability into multiple ones from software perspective, which
will benefit KVM and achieve other purposes such as QoS, security,
and etc.
Is there any actual users of this API around yet? How was it tested as
there is no hardware to test on? Which drivers are going to have to be
rewritten to take advantage of this new interface?
Yes, the API is used by Intel, HP, NextIO and some other anonymous
companies as they rise questions and send me feedback. I haven't seen
their works but I guess some of drivers using SR-IOV API are going to be
released soon.
My test was done with Intel 82576 Gigabit Ethernet Controller. The
product brief is at
http://download.intel.com/design/network/ProdBrf/320025.pdf and the spec
is available at
