Hardware-realized virtio_pci devices can implement SR-IOV, so this
patch enables its use. The device in question is an upcoming Intel
NIC that implements both a virtio_net PF and virtio_net VFs. These
are hardware realizations of what has been up to now been a software
inter
From: Alexander Duyck
This patch is meant to allow assignment of an SR-IOV enabled PF, as in VFs
have been generated, with vfio-pci. My understanding is the primary use
case for this is something like DPDK running the PF while the VFs are all
assigned to guests.
A secondary effect of this is tha
This series is meant to add support for SR-IOV on devices when the VFs are
not managed by the kernel. Examples of recent patches attempting to do this
include:

pci-stub - https://patchwork.kernel.org/patch/10109935/
vfio - https://patchwork.kerne
From: Alexander Duyck
This patch is meant to add some basic functionality to support for SR-IOV
on devices when the VFs are not managed by the kernel. The functions
provided here can be used by drivers such as vfio-pci and virtio to enable
SR-IOV on devices that are either managed by userspace, o

The new feature enables the virtio-balloon device to receive hints of
guest free pages from the free page vq. Callers call the
free_page_start API to start the reporting, which creates a thread to
poll for free page hints. The free_page_stop API stops the reporting and
makes the thread exit.

This patch adds an API to clear bits corresponding to guest free pages
from the dirty bitmap. Spilt the free page block if it crosses the QEMU
RAMBlock boundary.

This is the deivce part implementation to add a new feature,
VIRTIO_BALLOON_F_FREE_PAGE_HINT to the virtio-balloon device. The device
receives the guest free page hints from the driver and clears the
corresponding bits in the dirty bitmap, so that those free pages are
not transferred by the migrati
Start the free page optimization when the bulk stage starts. In case the
guest is slow in reporting, actively stops it when the bulk stage ends.
The optimization avoids sending guest free pages during the bulk stage.
Currently, the optimization is added to precopy only.
