Russell King did the following back in 2003: <-- snip --> [PCI] pci-9: Kill per-architecture pcibios_update_resource() Kill pcibios_update_resource(), replacing it with pci_update_resource(). pci_update_resource() uses pcibios_resource_to_bus() to convert a resource to a device BAR - the transformation should be exactly the same as the transformation used for the PCI bridges. pci_update_resource "knows" about 64-bit BARs, but doesn't attempt to set the high 32-bits to anything non-zero - currently no architecture attempts to do something different. If anyone cares, please fix; I'm going to reflect current behaviour for the time being. Ivan pointed out the following architectures need to examine their pcibios_update_resource() implementation - they should make sure that this new implementation does the right thing. #warning's have been added where appropriate. ia64 mips mips64 This cset also includes a fix for the problem reported by AKPM where 64-bit arch compilers complain about the resource mask being placed in a u32. <-- snip --> This patch removes the unused pcibios_update_resource() functions the kernel gained since, from FRV, m68k, mips & sh architectures.

Currently, pciehp driver enables command completed interrupt as follows. (1) Don't enable at initialization. (2) Enable command completed interrupt whenever pciehp issues a command, if the command doesn't attempt to disable the interrupt. (3) Disable command completed interrupt at driver unloading. Once we enable command completed interrupt, we don't need to re-enable it for every command. So we can simplify above steps as follows: (1) Enable command completed interrupt at initialization. (2) No special sequence for command completed interrupt. (3) Disable command completed interrupt at driver unloading.

Current pciehp driver's intialization sequence is as follows: (1) initialize controller data structure (2) install interrupt handler (3) enable software notification (4) initialize controller specific slot data structure (5) initialize generic slot data structure and register it to pci hotplug core The interrupt handler of pciehp assumes that controller specific slot data structure is already initialized. However, it is installed at (2) before initializing controller specific slot data structure at (4). Because of this, pciehp driver cannot handle the following cases properly. - If devices that shares IRQ with pciehp raise interrupts between (2) and (4). - If hotplug events (e.g. MRL open) happen between (3) and (4). We already have a workaround for this problem ("pciehp: fix NULL dereference in interrupt handler: dbd79aed). But we still need fundamental fix. This patch fix the problem by changing the initilization sequence as follows: (1) initialize controller data structure (2) initialize controller specific slot data structure (3) install interrupt handler (4) enable software notification (5) initialize generic slot data structure and register it to pci hotplug core Signed-off-by: NKenji Kaneshige <kaneshige.kenji@jp.fujitsu.com> Acked-by: NAlex Chiang <achiang@hp.com> Signed-off-by: NJesse Barnes <jbarnes@virtuousgeek.org>

Convert printks to use dev_printk(). I converted pr_debug() to dev_dbg(). Both use KERN_DEBUG and are enabled only when DEBUG is defined. I converted printk(KERN_DEBUG) to dev_printk(KERN_DEBUG), not to dev_dbg(), because dev_dbg() is only enabled when DEBUG is defined. I converted DBG(KERN_INFO) (only in setup-bus.c) to dev_info(). The DBG() name makes it sound like debug, but it's been enabled forever, so dev_info() preserves the previous behavior. I tried to make the resource assignment formats more consistent, e.g., "BAR %d: got res [%#llx-%#llx] bus [%#llx-%#llx] flags %#lx\n" instead of sometimes using "start-end" and sometimes using "size@start". I'm not attached to one or the other; I'd just like them consistent. Signed-off-by: NBjorn Helgaas <bjorn.helgaas@hp.com> Signed-off-by: NJesse Barnes <jbarnes@virtuousgeek.org>

On x86, we do early PCI probing to apply some quirks for chipset bugs. However, in a recent cleanup (7bcbc78d) a thinko was introduced that causes us to probe all subfunctions of even single function devices (a function was factored out of an inner loop and a "break" became a "return"). Fix that up by making check_dev_quirk() return a value so we can keep the factored code intact. Acked-by: NIngo Molnar <mingo@elte.hu> Signed-off-by: NJesse Barnes <jbarnes@virtuousgeek.org>

ACPI PM: Add possibility to change suspend sequence There are some systems out there that don't work correctly with our current suspend/hibernation code ordering. Provide a workaround for these systems allowing them to pass 'acpi_sleep=old_ordering' in the kernel command line so that it will use the pre-ACPI 2.0 ("old") suspend code ordering. Unfortunately, this requires us to add a platform hook to the resuming of devices for recovering the platform in case one of the device drivers' .suspend() routines returns error code. Namely, ACPI 1.0 specifies that _PTS should be called before suspending devices, but _WAK still should be called before resuming them in order to undo the changes made by _PTS. However, if there is an error during suspending devices, they are automatically resumed without returning control to the PM core, so the _WAK has to be called from within device_resume() in that cases. The patch also reorders and refactors the ACPI suspend/hibernation code to avoid duplication as far as reasonably possible. Signed-off-by: NRafael J.

Currently, /sys/bus/pci/slots/ only exposes hotplug attributes when a hotplug driver is loaded, but PCI slots have attributes such as address, speed, width, etc. that are not related to hotplug at all. Introduce pci_slot as the primary data structure and kobject model. Hotplug attributes described in hotplug_slot become a secondary structure associated with the pci_slot. This patch only creates the infrastructure that allows the separation of PCI slot attributes and hotplug attributes. In this patch, the PCI hotplug core remains the only user of this infrastructure, and thus, /sys/bus/pci/slots/ will still only become populated when a hotplug driver is loaded. A later patch in this series will add a second user of this new infrastructure and demonstrate splitting the task of exposing pci_slot attributes from hotplug_slot attributes. - Make pci_slot the primary sysfs entity. hotplug_slot becomes a subsidiary structure. o pci_create_slot() creates and registers a slot with the PCI core o pci_slot_add_hotplug() gives it hotplug capability - Change the prototype of pci_hp_register() to take the bus and slot number (on parent bus) as parameters. - Remove all the ->get_address methods since this functionality is now handled by pci_slot directly.
