HI, For SRIOV support, currently in the KVM environment, mpt3sas driver can use the API pci_vfs_assigned() to know the number of VFs that are currently assigned to the running VMs. So that during the PF driver unload time, if the return value of this API is greater than zero the our driver won't call the pci_disable_sriov() to disable the VFs.
Now for the same purpose in XEN environment, is there any API similar to pci_vfs_assigned() which the low lever device driver can use to know 'the number of VFs that are currently assigned to the running VMs'. In XEN environment this API pci_vfs_assigned() will return always zero even though VFs are assigned to the running VMs. Regards, Sreekanth -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
