I have been carrying it, rebasing it and\npersonally using it for a while now though.\n\nThis series attempts to unify the PCI suspend and hibernate paths and to\nfix some things that I observed to be wrong with how I expect hibernate\nto work.\n\nIt is based off 7.1-rc1 + Lukas' patch:\n\"PCI: Stop setting cached power state to \"unknown\" on unbind\"\n\nMario Limonciello (AMD) (5):\n PCI/PM: Disable device wakeups when halting or powering off system\n PCI/PM: Split out code from pci_pm_suspend_noirq() into helper\n PCI/PM: Run bridge power up actions as part of restore phase\n PCI/PM: Use pci_power_manageable() in pci_pm_poweroff_noirq()\n PCI: Put PCIe bridges with downstream devices into D3 at hibernate\n\n drivers/pci/pci-driver.c | 103 ++++++++++++++++++++++++++-------------\n 1 file changed, 69 insertions(+), 34 deletions(-)" }
