Subject: [Qemu-devel] [RFC PATCH v4 0/3] Add Mediated device support[was: Add vGPU support]
Date: Wed, 25 May 2016 01:28:14 +0530 [thread overview]
Message-ID: <1464119897-10844-1-git-send-email-kwankhede@nvidia.com> (raw)
This series adds Mediated device support to v4.6 Linux host kernel. Purpose
of this series is to provide a common interface for mediated device
management that can be used by different devices. This series introduces
Mdev core module that create and manage mediated devices, VFIO based driver
for mediated PCI devices that are created by Mdev core module and update
VFIO type1 IOMMU module to support mediated devices.
What's new in v4?
- Renamed 'vgpu' module to 'mdev' module that represent generic term
'Mediated device'.
- Moved mdev directory to drivers/vfio directory as this is the extension
of VFIO APIs for mediated devices.
- Updated mdev driver to be flexible to register multiple types of drivers
to mdev_bus_type bus.
- Updated mdev core driver with mdev_put_device() and mdev_get_device() for
mediated devices.
What's left to do?
VFIO driver for vGPU device doesn't support devices with MSI-X enabled.
Please review.
