PCI: Remove empty asm-generic/pci-bridge.h

2016-02-05T22:29:19Z

include/asm-generic/pci-bridge.h is empty, and nobody includes it, so remove it. Signed-off-by: Bjorn Helgaas

PCI: Move pci_set_flags() from asm-generic/pci-bridge.h to linux/pci.h

2016-02-05T22:28:11Z

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

PCI: work around Stratus ftServer broken PCIe hierarchy

2012-04-30T21:21:02Z

A PCIe downstream port is a P2P bridge. Its secondary interface is a link that should lead only to device 0 (unless ARI is enabled)[1], so we don't probe for non-zero device numbers. Some Stratus ftServer systems have a PCIe downstream port (02:00.0) that leads to both an upstream port (03:00.0) and a downstream port (03:01.0), and 03:01.0 has important devices below it: [0000:02]-+-00.0-[03-3c]--+-00.0-[04-09]--... \-01.0-[0a-0d]--+-[USB] +-[NIC] +-... Previously, we didn't enumerate device 03:01.0, so USB and the network didn't work. This patch adds a DMI quirk to scan all device numbers, not just 0, below a downstream port. Based on a patch by Prarit Bhargava.

PCI: add pci_clear_flags()

2012-02-24T03:18:56Z

Add a pci_clear_flags() for cases when we statically initialize pci_flags, then decide to clear things out later. Signed-off-by: Bjorn Helgaas

pci: move microblaze and powerpc pci flag functions into asm-generic

2011-07-12T16:13:07Z

Move separate microblaze and powerpc pci flag functions pci_set_flags, pci_add_flags, and pci_has_flag into asm-generic/pci-bridge.h so other archs can use them. Signed-off-by: Rob Herring Acked-by: Nicolas Pitre Acked-by: Benjamin Herrenschmidt Cc: Jesse Barnes Signed-off-by: Michal Simek
