Hi Dominik,

do you want to create some kind of pool of pci devices in your ""add cluster-wide hardware device mapping" patches series ?

Maybe in hardwaremap, allow to define multiple pci address on same node ?

Then, for mdev, look if a mdev already exist in 1 of the device.
If not, try to create the mdev if 1 device, if it's failing (max number of mdev reached), try to create mdev on the other device,...

if not mdev, choose a pci device in the pool not yet detached from host.
