I dropped the DPC pcie_ports_dpc_native changes for now just because I haven't had time to understand it all. We currently ignore the OSC_PCI_EXPRESS_DPC_CONTROL bit, which seems wrong. We might want to start looking at it, but we should try to make that a separate patch that's as small as possible. Changes since v11: * Add bugfix for DPC with no AER Capability * Split OSC_OWNER trivial changes from pcie_ports_native changes * Temporarily drop pcie_ports_dpc_native changes v11 posting: https://lore.kernel.org/r/cover.1603766889.git.sathyanarayanan.kuppuswamy@linux.intel.com Bjorn Helgaas (2): PCI/DPC: Ignore devices with no AER Capability PCI/ACPI: Centralize pci_aer_available() checking Kuppuswamy Sathyanarayanan (3): PCI: Assume control of portdrv-related features only when portdrv enabled PCI/ACPI: Tidy _OSC control bit checking PCI/ACPI: Centralize pcie_ports_native checking drivers/acpi/pci_root.c | 49 ++++++++++++++++++++++++------- drivers/pci/hotplug/pciehp_core.c | 2 +- drivers/pci/pci-acpi.c | 3 -- drivers/pci/pcie/aer.c | 2 +- drivers/pci/pcie/dpc.c | 3 ++ drivers/pci/pcie/portdrv_core.c | 9 ++---- drivers/pci/probe.c | 6 ++-- 7 files changed, 50 insertions(+), 24 deletions(-) -- 2.25.1
