6:29 a.m.
This first version of this series was reviewed quite a while ago and all
patches were ACKed except the second one. I posted a second series with changes
noted below but it was never ACKed and I dropped the ball for a little while.
Subsequently there were questions about whether physical devices (e.g. pci,
usb, etc) should return 'true' or 'false' for the
GetAutostart()/IsPersistent()
calls. I had initially marked them as persistent=true and autostart=true
because they superficially act a bit like persistently-defined devices. But
Boris convinced me that this is not a very accurate classification since if the
physical device is unplugged, there will be no record of it left behind. So
I've switched all non-mdev devices to be persistent=false and autostart=false.
This is also imperfect, but it seems relatively harmless. Comments welcome.
A reminder of what is included in this series:
- new API consistent with existing libvirt objects:
- virNodeDeviceGetAutostart()
- virNodeDeviceSetAutostart()
- virNodeDeviceIsPersistent()
- virNodeDeviceIsActive
- new virsh commands
- nodedev-info
- nodedev-autostart
Changes in version 2:
- Parse the autostart property from mdevctl output.
Changes in version 3:
- switch physical devices to autostart=false, persistent=false
- rebase to upstream
- update version numbers for new API, etc
- fix accidental copy-paste error in virsh command descriptions
Jonathon Jongsma (7):
api: add virNodeDevice(Get|Set)Autostart()
nodedev: implement virNodeDevice(Get|Set)Autostart()
nodedev: Add tests for mdevctl autostart command
virsh: add nodedev-autostart
api: add virNodeDeviceIsPersistent()/IsActive()
nodedev: Implement virNodeDeviceIsPersistent()/IsActive()
virsh: add nodedev-info

New subject: [libvirt PATCH v3 1/7] api: add virNodeDevice(Get|Set)Autostart()
This will allow persistent mediated devices to be configured to be
restarted automatically when the host reboots.

New subject: [libvirt PATCH v3 5/7] api: add virNodeDeviceIsPersistent()/IsActive()
These two public APIs are implemented for almost all other objects that
have a concept of persistent definition and activatability. Now that we
have node devices (mdevs) that can be defined and inactive, it will be
useful to query the persistent/active state of node devices as well.

Ping
Can I get a review on this? As I mentioned in the cover letter, the
only patch that was not initially ACKed in the last version was the
second one. However, the non-mdev devices were also switched to to
persistent=false and autostart=false.

Subsequently there were questions about whether physical devices (e.g. pci,
usb, etc) should return 'true' or 'false' for the
GetAutostart()/IsPersistent()
calls. I had initially marked them as persistent=true and autostart=true
because they superficially act a bit like persistently-defined devices. But
Boris convinced me that this is not a very accurate classification since if the
physical device is unplugged, there will be no record of it left behind. So
I've switched all non-mdev devices to be persistent=false and autostart=false.
This is also imperfect, but it seems relatively harmless. Comments welcome.
A reminder of what is included in this series:
- new API consistent with existing libvirt objects:
- virNodeDeviceGetAutostart()
- virNodeDeviceSetAutostart()
- virNodeDeviceIsPersistent()
- virNodeDeviceIsActive
- new virsh commands
- nodedev-info
- nodedev-autostart
Changes in version 2:
- Parse the autostart property from mdevctl output.
Changes in version 3:
- switch physical devices to autostart=false, persistent=false
- rebase to upstream
- update version numbers for new API, etc
- fix accidental copy-paste error in virsh command descriptions

Sorry for the delay.
