(Before the HW\nfault the PF was allocated hence the VFs was marked unavailable).\n\nIn this state this PF is still schedulable but during the\nPCI claim the handling of dependent devices in the PCI tracker fill fail\nwith the error: \"Attempt to consume PCI device XXX from empty pool\".\n\nThe reason of the failure is that when the PF is claimed, all the\nchildren VFs are marked unavailable. But if the VF is already\nunavailable such step fails.\n\nOne way the deployer might try to recover from this state is to remove\nthe VFs from the hypervisor and restart the compute agent. The compute\nstartup already has a logic to delete PCI devices that are unused and\nnot reported by the hypervisor. However this logic only removed devices\nin \u0027available\u0027 state and ignored devices in \u0027unavailable\u0027 state.\n\nIf a device is unused and the hypervisor is not reporting the device any\nmore then it is safe to delete that device from the PCI tracker. So this\npatch extends the logic to allow deleting \u0027unavailable\u0027 devices. There\nis a small window when dependent PCI device is in \u0027unclaimable\u0027 state.\nFrom cleanup perspective this is an analogous state.

(Before the HW\nfault the PF was allocated hence the VFs was marked unavailable).\n\nIn this state this PF is still schedulable but during the\nPCI claim the handling of dependent devices in the PCI tracker fill fail\nwith the error: \"Attempt to consume PCI device XXX from empty pool\".\n\nThe reason of the failure is that when the PF is claimed, all the\nchildren VFs are marked unavailable. But if the VF is already\nunavailable such step fails.\n\nOne way the deployer might try to recover from this state is to remove\nthe VFs from the hypervisor and restart the compute agent. The compute\nstartup already has a logic to delete PCI devices that are unused and\nnot reported by the hypervisor. However this logic only removed devices\nin \u0027available\u0027 state and ignored devices in \u0027unavailable\u0027 state.\n\nIf a device is unused and the hypervisor is not reporting the device any\nmore then it is safe to delete that device from the PCI tracker. So this\npatch extends the logic to allow deleting \u0027unavailable\u0027 devices. There\nis a small window when dependent PCI device is in \u0027unclaimable\u0027 state.\nFrom cleanup perspective this is an analogous state.
