From: Bjorn Helgaas <bhelgaas@xxxxxxxxxx> This is Sathy's work with a few tweaks on top. 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.
Along with above patch, you also left following two cleanup patches. Is this intentional? Following fixes have no dependency on pcie_ports_dpc_native change. [PATCH v11 4/5] PCI/portdrv: Remove redundant pci_aer_available() check in DPC enable logic [PATCH v11 5/5] PCI/DPC: Move AER/DPC dependency checks out of DPC driver
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@xxxxxxxxxxxxxxx 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(-)
