2017-11-07PCI: Add for_each_pci_bridge() helperAndy Shevchenko1-3/+2
The following pattern is often used: list_for_each_entry(dev, &bus->devices, bus_list) { if (pci_is_bridge(dev)) { ... } } Add a for_each_pci_bridge() helper to make that code easier to write and read by reducing indentation level. It also saves one or few lines of code in each occurrence. Convert PCI core parts here at the same time.

2014-01-14pcmcia: Use global PCI rescan-remove lockingRafael J. Wysocki1-0/+7
Multiple race conditions are possible between the cardbus PCI device addition and removal and the generic PCI bus rescan and device removal that can be triggered via sysfs. To avoid those race conditions make the cardbus code use global PCI rescan-remove locking. Signed-off-by: Rafael J.

2013-07-25PCI: Delay enabling bridges until they're neededYinghai Lu1-1/+0
We currently enable PCI bridges after scanning a bus and assigning resources. This is often done in arch code. This patch changes this so we don't enable a bridge until necessary, i.e., until we enable a PCI device behind the bridge. We do this in the generic pci_enable_device() path, so this also removes the arch-specific code to enable bridges.

2012-08-22pcmcia: Use common pci_stop_and_remove_bus_device()Bjorn Helgaas1-3/+12
Use pci_stop_and_remove_bus_device() like most other hotplug drivers rather than the special-purpose "behind_bridge" variant. This just means we have to iterate through all the devices downstream of the bridge ourselves, which is the same thing pci_stop_behind_bridge() did.

2012-06-14PCI: replace struct pci_bus secondary/subordinate with busn_resYinghai Lu1-1/+1
Replace the struct pci_bus secondary/subordinate members with the struct resource busn_res. Later we'll build a resource tree of these bus numbers. [bhelgaas: changelog] Signed-off-by: Yinghai Lu <yinghai@kernel.org> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
2012-02-28PCI: Rename pci_remove_behind_bridge to pci_stop_and_remove_behind_bridgeYinghai Lu1-1/+1

2010-03-03pcmcia: CodingStyle fixesDominik Brodowski1-1/+1
Fix most of the remaining CodingStyle issues in drivers/pcmcia , which related to wrong indent -- PCMCIA historically used 4 spaces. Also, remove a custom min() implementation with the generic one. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
2010-01-17pcmcia: CardBus doesn't need CIS accessDominik Brodowski1-161/+14
At least no in-kernel CardBus-capable PCI driver makes use of the CIS access functions. Therefore, it seems sensible to remove this unused code, and cleanup cardbus.c a lot.

2009-12-17PCI/cardbus: Add a fixup hook and fix powerpcBenjamin Herrenschmidt1-1/+1
The cardbus code creates PCI devices without ever going through the necessary fixup bits and pieces that normal PCI devices go through. There's in fact a commented out call to pcibios_fixup_bus() in there, it's commented because ... it doesn't work. I could make pcibios_fixup_bus() do the right thing on powerpc easily but I felt it cleaner instead to provide a specific hook pci_fixup_cardbus for which a weak empty implementation is provided by the PCI core. This fixes cardbus on powerbooks and probably all other PowerPC platforms which was broken completely for ever on some platforms and since 2.6.31 on others such as PowerBooks when we made the DMA ops mandatory (since those are setup by the fixups).

2009-12-08pcmcia: CodingStyle fixesDominik Brodowski1-11/+12
Fix several CodingStyle issues in drivers/pcmcia/ . checkpatch.pl no longer reports errors in the PCMCIA core. The remaining warnings mostly relate to wrong indent -- PCMCIA historically used 4 spaces --, to lines over 80 characters and to hundreds of typedefs. The cleanup of those will follow in the future.

2009-11-08pcmcia: use dynamic debug instead of custom infrastructureDominik Brodowski1-2/+2
Use the generic "dynamic debug" infrastructure instead of CONIG_PCMCIA_DEBUG in the PCMCIA core (pcmcia.ko and pcmcia_core.ko). To enable debugging, enable CONFIG_DYNAMIC_DEBUG, mount debugfs and $ echo -n 'module pcmcia_core +p' > /sys/kernel/debug/dynamic_debug/control for the complete module "pcmcia_core", for example.

2009-11-04pccard: configure CLS on attachTejun Heo1-8/+15
For non hotplug PCI devices, the system firmware usually configures CLS correctly. For pccard devices system firmware can't do it and Linux PCI layer doesn't do it either. Unfortunately this leads to poor performance for certain devices (sata_sil). Unless MWI, which requires separate configuration, is to be used, CLS doesn't affect correctness, so the configuration should be harmless. This patch makes pci_set_cacheline_size() always built and export it and make pccard call it during attach. Please note that some other PCI hotplug drivers (shpchp and pciehp) also configure CLS on hotplug.

2005-09-26[PATCH] yenta: auto-tune EnE bridges for CardBus cardsDaniel Ritz1-0/+5
Echo Audio cardbus products are known to be incompatible with EnE bridges. in order to maybe solve the problem a EnE specific test bit has to be set, another cleared...but other setups have a good chance to break when just forcing the bits. so do the whole thingy automatically. The patch adds a hook in cb_alloc() that allows special tuning for the different chipsets. for ene just match the Echo products and set/clear the test bits, defaults to do the same thing as w/o the patch to not break working setups.

2005-04-17Linux-2.6.12-rc2Linus Torvalds1-0/+247
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
