ACPI requires to run acpi_pci_{add|remove}_bus while new PCI bus is created.
This allows to do some ACPI-specific additional configuration, like
PCI hotplug slot enumeration. In order to fulfill these requirements,
we implement arch-specific pcibios_{add|remove}_bus calls
and call acpi_pci_{add|remove}_bus from there.Signed-off-by: Tomasz Nowicki <[email protected]> To: Catalin Marinas <[email protected]> To: Lorenzo Pieralisi <[email protected]> To: Will Deacon <[email protected]> To: Arnd Bergmann <[email protected]> --- arch/arm64/kernel/pci.c | 11 +++++++++++ 1 file changed, 11 insertions(+) diff --git a/arch/arm64/kernel/pci.c b/arch/arm64/kernel/pci.c index 15109c11..eeec5f6 100644 --- a/arch/arm64/kernel/pci.c +++ b/arch/arm64/kernel/pci.c @@ -17,6 +17,7 @@ #include <linux/mm.h> #include <linux/of_pci.h> #include <linux/of_platform.h> +#include <linux/pci-acpi.h> #include <linux/slab.h> /* @@ -64,6 +65,16 @@ int pcibios_alloc_irq(struct pci_dev *dev) return 0; } +void pcibios_add_bus(struct pci_bus *bus) +{ + acpi_pci_add_bus(bus); +} + +void pcibios_remove_bus(struct pci_bus *bus) +{ + acpi_pci_remove_bus(bus); +} + /* * raw_pci_read/write - Platform-specific PCI config space access. */ -- 1.9.1
