[libvirt PATCH 0/4] increase locked memory limit when a vDPA device is present

Posted by Laine Stump 3 years ago

We recently learned that vDPA devices may/will need to pin/lock all of
guest memory, and so just as we do for VFIO devices, we need to
increase the locked memory limit when a vDPA device is present.

  conf: new function virDomainDefHasVDPANet()
  qemu: simplify qemuDomainGetMemLockLimitBytes()
  qemu: account for mdev devices in getPPC64MemLockLimitBytes()
  qemu: increase locked memory limit when a vDPA device is present
