Hi, The following patchset is based on https://patchwork.kernel.org/patch/114917/ and the comments I received on that patch. Hopefully, I took all of the comments into account. [1/7] - Remove the last argument of acpi_pci_osc_run(); this is a cleanup, but IMO it makes sense. [2/7] - Introduce acpi_pci_root_osc_query() allowing the caller to get a mask of _OSC control bits the BIOS allows the kernel to control for a given PCI root bridge. [3/7] - Rework the PCIe port driver to request _OSC control for all serives at once. [4/7] - Disable PCIe port services (that might be enabled by the BIOS) during initialization. [5/7] - Remove the PCIe port driver modules exit function. [6/7] - Rework acpi_pci_osc_control_set() so that it doesn't use cached result of a query and remove the fields of struct acpi_pci_root that aren't used any more. [7/7] - Reorder checks in acpi_pci_osc_control_set() Comments (and testing :-)) welcome.
