[GIT PULL 00/22] KVM: s390: Changes for 6.6

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello Paolo,

please pull the following changes for 6.6.

Please note that Heiko and I both merged Heiko's vfio-ap feature
branch. We had to do that since vfio-ap patches go through his s390
repository but Steffen's KVM cpumodel patches are based on Tony's
vfio-ap changes.

In the long run we're considering putting vfio-ap patches into their
own repository but for 6.6 we didn't find the time to speak with all
affected maintainers.

- PV crypto passthrough enablement (Tony, Steffen, Viktor, Janosch)
  Allows a PV guest to use crypto cards. Card access is governed by
  the firmware and once a crypto queue is "bound" to a PV VM every
  other entity (PV or not) looses access until it is not bound
  anymore. Enablement is done via flags when creating the PV VM.

- Guest debug fixes (Ilya)
