PCI: hotplug: Add hotplug_is_native()

2018-06-04T17:08:06Z

Add hotplug_is_native() to find out whether the OS is supposed to handle native hotplug of a given bridge. Signed-off-by: Mika Westerberg Signed-off-by: Bjorn Helgaas Reviewed-by: Rafael J. Wysocki Reviewed-by: Andy Shevchenko

PCI: shpchp: Add shpchp_is_native()

2018-06-04T17:08:06Z

In the same way we do for pciehp, add shpchp_is_native(), which returns true if the bridge should be handled by the native SHPC driver. Then convert the driver to use this function. Signed-off-by: Mika Westerberg Signed-off-by: Bjorn Helgaas

PCI: shpchp: Remove get_hp_hw_control_from_firmware() wrapper

2018-06-02T05:18:28Z

get_hp_hw_control_from_firmware() is a trivial wrapper around acpi_get_hp_hw_control_from_firmware(), probably intended to be generic in case other firmware needed similar OS/platform negotiation. Remove get_hp_hw_control_from_firmware() and call acpi_get_hp_hw_control_from_firmware() directly. Add a stub for acpi_get_hp_hw_control_from_firmware() for the non-ACPI case.

PCI: shpchp: Remove acpi_get_hp_hw_control_from_firmware() flags

2018-06-02T05:18:28Z

acpi_get_hp_hw_control_from_firmware() no longer uses the flags parameter, so remove it. Signed-off-by: Mika Westerberg [bhelgaas: split to separate patch] Signed-off-by: Bjorn Helgaas Reviewed-by: Rafael J. Wysocki

PCI: pciehp: Make pciehp_is_native() stricter

2018-06-02T05:18:28Z

Previously pciehp_is_native() returned true for any PCI device in a hierarchy where _OSC says we can use pciehp. This is incorrect because bridges without PCI_EXP_SLTCAP_HPC capability should be managed by acpiphp instead. Improve pciehp_is_native() to return true only when PCI_EXP_SLTCAP_HPC is set and the pciehp driver is present. In any other case return false to let acpiphp handle those.

PCI: Add SPDX GPL-2.0+ to replace GPL v2 or later boilerplate

2018-01-28T21:49:06Z

Add SPDX GPL-2.0+ to all PCI files that specified the GPL and allowed either GPL version 2 or any later version. Remove the boilerplate GPL version 2 or later language, relying on the assertion in b24413180f56 ("License cleanup: add SPDX GPL-2.0 license identifier to files with no license") that the SPDX identifier may be used instead of the full boilerplate text.

ACPI / hotplug / PCI: Make device_is_managed_by_native_pciehp() public

2016-11-18T00:47:58Z

We're about to add runtime PM of hotplug ports, but we need to restrict it to ports that are handled natively by the OS: If they're handled by the firmware (which is the case for Thunderbolt on non-Macs), things would break if the OS put the ports into D3hot behind the firmware's back. To determine if a hotplug port is handled natively, one has to walk up from the port to the root bridge and check the cached _OSC Control Field for the value of the "PCI Express Native Hot Plug control" bit. There's already a function to do that, device_is_managed_by_native_pciehp(), but it's private to drivers/pci/hotplug/acpiphp_glue.c and only compiled in if CONFIG_HOTPLUG_PCI_ACPI is enabled. Make it public and move it to drivers/pci/pci-acpi.c, so that it is available in the more general CONFIG_ACPI case. The function contains a check if the device in question is a hotplug port and returns false if it's not. The caller we're going to add doesn't need this as it only calls the function if it actually *is* a hotplug port. Move the check out of the function into the single existing caller. Rename it to pciehp_is_native() and add some kerneldoc and polish. No functional change intended.

PCI: Remove unused and broken to_hotplug_slot()

2014-11-13T17:35:25Z

to_hotplug_slot() is unused and wouldn't work anyway, because struct hotplug_slot no longer contains a struct kobject (it was removed by f46753c5e354 ("PCI: introduce pci_slot")). Remove to_hotplug_slot(). [bhelgaas: changelog] Signed-off-by: Gavin Shan Signed-off-by: Bjorn Helgaas

ACPI: Clean up inclusions of ACPI header files

2013-12-07T00:03:14Z

Replace direct inclusions of , and , which are incorrect, with inclusions and remove some inclusions of those files that aren't necessary. First of all, , and should not be included directly from any files that are built for CONFIG_ACPI unset, because that generally leads to build warnings about undefined symbols in !CONFIG_ACPI builds. For CONFIG_ACPI set, includes those files and for CONFIG_ACPI unset it provides stub ACPI symbols to be used in that case. Second, there are ordering dependencies between those files that always have to be met. Namely, it is required that be included prior to so that the acpi_pci_root declarations the latter depends on are always there. And which provides basic ACPICA type declarations should always be included prior to any other ACPI headers in CONFIG_ACPI builds. That also is taken care of including as appropriate.
