From 5bbe029ff7bc8ff82ef31d3480d68c95642a3c7a Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Fri, 5 Feb 2016 14:57:47 -0600 Subject: PCI: Move pci_set_flags() from asm-generic/pci-bridge.h to linux/pci.h The PCI flag management constants and functions were previously declared in include/asm-generic/pci-bridge.h. But they are not specific to bridges, and arches did not include pci-bridge.h consistently. Move the following interfaces and related constants to include/linux/pci.h and remove pci-bridge.h: pci_set_flags() pci_add_flags() pci_clear_flags() pci_has_flag() This fixes these warnings when building for some arches: drivers/pci/host/pcie-designware.c:562:20: error: 'PCI_PROBE_ONLY' undeclared (first use in this function) drivers/pci/host/pcie-designware.c:562:7: error: implicit declaration of function 'pci_has_flag' [-Werror=implicit-function-declaration] Signed-off-by: Bjorn Helgaas --- include/linux/pci.h | 22 ++++++++++++++++++++++ 1 file changed, 22 insertions(+) (limited to 'include/linux/pci.h') diff --git a/include/linux/pci.h b/include/linux/pci.h index 27df4a6585da..3d371c150753 100644 --- a/include/linux/pci.h +++ b/include/linux/pci.h @@ -746,9 +746,26 @@ struct pci_driver { .vendor = PCI_VENDOR_ID_##vend, .device = (dev), \ .subvendor = PCI_ANY_ID, .subdevice = PCI_ANY_ID, 0, 0 +enum { + PCI_REASSIGN_ALL_RSRC = 0x00000001, /* ignore firmware setup */ + PCI_REASSIGN_ALL_BUS = 0x00000002, /* reassign all bus numbers */ + PCI_PROBE_ONLY = 0x00000004, /* use existing setup */ + PCI_CAN_SKIP_ISA_ALIGN = 0x00000008, /* don't do ISA alignment */ + PCI_ENABLE_PROC_DOMAINS = 0x00000010, /* enable domains in /proc */ + PCI_COMPAT_DOMAIN_0 = 0x00000020, /* ... except domain 0 */ + PCI_SCAN_ALL_PCIE_DEVS = 0x00000040, /* scan all, not just dev 0 */ +}; + /* these external functions are only available when PCI support is enabled */ #ifdef CONFIG_PCI +extern unsigned int pci_flags; + +static inline void pci_set_flags(int flags) { pci_flags = flags; } +static inline void pci_add_flags(int flags) { pci_flags |= flags; } +static inline void pci_clear_flags(int flags) { pci_flags &= ~flags; } +static inline int pci_has_flag(int flag) { return pci_flags & flag; } + void pcie_bus_configure_settings(struct pci_bus *bus); enum pcie_bus_config_types { @@ -1405,6 +1422,11 @@ void pci_register_set_vga_state(arch_set_vga_state_t func); #else /* CONFIG_PCI is not enabled */ +static inline void pci_set_flags(int flags) { } +static inline void pci_add_flags(int flags) { } +static inline void pci_clear_flags(int flags) { } +static inline int pci_has_flag(int flag) { return 0; } + /* * If the system does not have PCI, clearly these return errors.
