This patch series follows the previously-merged series which added support for
transient mediated devices. This series expands mdev support to include
persistent device definitions. Again, it relies on mdevctl as the backend.
It follows the common libvirt pattern of APIs by adding the following new APIs
for node devices:
- virNodeDeviceDefineXML() - defines a persistent device
- virNodeDeviceUndefine() - undefines a persistent device
- virNodeDeviceCreate() - starts a previously-defined device
It also adds virsh commands mapping to these new APIs: nodedev-define,
nodedev-undefine, and nodedev-start.
The method of staying up-to-date with devices defined by mdevctl is currently=
a
little bit crude due to the fact that mdevctl does not emit any events when n=
ew
devices are added or removed. As a workaround, we create a file monitor for t=
he
mdevctl config directory and re-query mdevctl when we detect changes within
that directory. In the future, mdevctl may introduce a more elegant solution.
Changes in v2:
- rebase to latest git master
Jonathon Jongsma (16):
tests: remove extra trailing semicolon
nodedev: introduce concept of 'active' node devices
nodedev: Add ability to filter by active state
virsh: Add --active, --inactive, --all to nodedev-list
nodedev: add ability to list and parse defined mdevs
nodedev: add STOPPED/STARTED lifecycle events
nodedev: add mdevctl devices to node device list
nodedev: handle mdevs that disappear from mdevctl
nodedev: add an mdevctl thread
api: add virNodeDeviceDefineXML()
virsh: add nodedev-define command
api: add virNodeDeviceUndefine()
virsh: Factor out function to find node device
virsh: add nodedev-undefine command
api: add virNodeDeviceCreate()
virsh: add "nodedev-start" command
