Subject: [dpdk-dev] [RFC v2 0/5] Add mdev (Mediated device) support in DPDK
Date: Mon, 15 Jul 2019 15:52:09 +0800 [thread overview]
Message-ID: <20190715075214.16616-1-tiwei.bie@intel.com> (raw)
In-Reply-To: <20190403071844.21126-1-tiwei.bie@intel.com>
Hi everyone,
This is a draft implementation of the mdev (Mediated device [1])
support in DPDK PCI bus driver. Mdev is a way to virtualize devices
in Linux kernel. Based on the device-api (mdev_type/device_api),
there could be different types of mdev devices (e.g. vfio-pci).
In this RFCv2, the PCI bus driver is extended to support scanning
and probing the mdev devices whose device-api is "vfio-pci".
+---------+
| PCI bus |

+--------+-------+-------+--------+
| | | |
Physical PCI devices ... Mediated PCI devices ...
RFCv2:
- Let PCI bus scan mediated PCI devices directly
- Address Keith's comments
- Merge below patch into this series (David)
http://patches.dpdk.org/patch/55927/
- Add internal representation of PCI device (David)
- Minor fixes and improvements

Thanks,

Tiwei Bie (5):
bus/pci: introduce an internal representation of PCI device
bus/pci: avoid depending on private value in kernel source
bus/pci: introduce helper for MMIO read and write
eal: add a helper for reading string from sysfs
bus/pci: add mdev support
