* PCI: handle long delays in VPD accessStephen Hemminger2009-01-071-22/+33
| | | | | | | | | | | | | | | Accessing the VPD area can take a long time. The existing VPD access code fails consistently on my hardware. There are comments in the SysKonnect vendor driver that it can take up to 13ms per word. Change the access routines to: * use a mutex rather than spinning with IRQ's disabled and lock held * have a much longer timeout * call cond_resched while spinning Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Reviewed-by: Matthew Wilcox <willy@linux.intel.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>

* PCI: add pci_common_swizzle() for INTx swizzlingBjorn Helgaas2009-01-072-0/+21
| | | | | | | | | | | | This patch adds pci_common_swizzle(), which swizzles INTx values all the way up to a root bridge. This common implementation can replace several architecture-specific ones. This should someday be combined with pci_get_interrupt_pin(), but I left it separate for now to make reviewing easier.

* PCI hotplug: introduce functions for ACPI slot detectionKenji Kaneshige2009-01-075-142/+100
| | | | | | | | | | | | | | | | | | | | | | | | | | Some ACPI related PCI hotplug code can be shared among PCI hotplug drivers. This patch introduces the following functions in drivers/pci/hotplug/acpi_pcihp.c to share the code, and changes acpiphp and pciehp to use them. - int acpi_pci_detect_ejectable(struct pci_bus *pbus) This checks if the specified PCI bus has ejectable slots. - int acpi_pci_check_ejectable(struct pci_bus *pbus, acpi_handle handle) This checks if the specified handle is ejectable ACPI PCI slot. The 'pbus' parameter is needed to check if 'handle' is PCI related ACPI object. This patch also introduces the following inline function in include/linux/pci-acpi.h, which is useful to get ACPI handle of the PCI bridge from struct pci_bus of the bridge's secondary bus. - static inline acpi_handle acpi_pci_get_bridge_handle(struct pci_bus *pbus) This returns ACPI handle of the PCI bridge which generates PCI bus specified by 'pbus'.

* PCI: pciehp: add auto option to pciehp_detect_modeKenji Kaneshige2009-01-071-4/+76
| | | | | | | | | | | | | | | | | | | ACPI based hot-pluggable PCIe slot detection logic was added to prevent the problem non hot-pluggable PCIe slot was detected as hot-pluggable. The slot detection logic can be selected through 'pciehp_detect_mode', but it would be better if it is selected automatically. This patch adds 'auto' option for 'pciehp_detect_mode'. When it is specified, pciehp judges which 'acpi' or 'pcie' should be used. It seems that the physical slot number is duplicated among some slots on most of the platforms with the above-mentioned problem. So 'auto' mode uses this information to judge which 'acpi' or 'pcie' should be used. That is, if duplicated physical slot numbers are detected, 'acpi' mode is used. This method is not perfect, but it's realistic. Signed-off-by: Kenji Kaneshige <kaneshige.kenji@jp.fujitsu.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
* PCI: pciehp: add ACPI based slot detectionKenji Kaneshige2009-01-074-1/+132
| | | | | | | | | | | | | | | | | | | | | There is a problem that some non hot-pluggable PCIe slots are detected as hot-pluggable by pciehp on some platforms. The immediate cause of this problem is that hot-plug capable bit in the Slot Capabilities register is set even for non hot-pluggable slots on those platforms. It seems a BIOS/hardware problem, but we need workaround about that. Some of those platforms define hot-pluggable PCIe slots on ACPI namespace properly, while hot-plug capable bit in the Slot Capabilities register is set improperly. So using ACPI namespace information in pciehp to detect PCIe hot-pluggable slots would be a workaround. This patch adds 'pciehp_detect_mode' module option. When 'acpi' is specified, pciehp uses ACPI namespace information to detect PCIe hot-pluggable slots.

| | | | | | | | | | | | | | | | This uses work_on_cpu(), rather than altering the cpumask of the thread which we happen to be. Note the cleanups: 1) I've removed the CONFIG_NUMA test, since dev_to_node() returns -1 for !CONFIG_NUMA anyway and the compiler will eliminate it. 2) No need to reset mempolicy to default (a bad idea anyway) since work_on_cpu is run from a workqueue.

* PCI PM: Split PCI Express port suspend-resumeRafael J. Wysocki2009-01-071-6/+17
| | | | | | | | | | | | Suspend-resume of PCI Express ports has recently been moved into _suspend_late() and _resume_early() callbacks, but some functions executed from there should not be called with interrupts disabled, eg. pci_enable_device().

* PCI PM: Fix pci_update_current_stateRafael J. Wysocki2009-01-071-3/+6
| | | | | | | | | | | | Currently, PCI devices without the PM capability that are power manageable by the platform (eg. ACPI) are not handled correctly by pci_set_power_state(), because their current_state field is not updated to reflect the new power state of the device. Fix this by making pci_update_current_state() accept additional argument representing the power state of the device as set by the platform. Signed-off-by: Rafael J.

* PCI: set device wakeup capable flag if platform support is presentJesse Barnes2009-01-073-0/+22
| | | | | | | | | | | | | When PCI devices are initialized, we check whether they support PCI PM caps and set the device can_wakeup flag if so. However, some devices may have platform provided wakeup events rather than PCI PME signals, so we need to set can_wakeup in that case too. Doing so should allow wakeups from many more devices, especially on cost constrained systems.

* PCI: Make settable sysfs attributes more consistentTrent Piepho2009-01-071-20/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | PCI devices have three settable boolean attributes, enable, broken_parity_status, and msi_bus. The store functions for these would silently interpret "0x01" as false, "1llogical" as true, and "true" would be (silently!) ignored and do nothing. This is inconsistent with typical sysfs handling of settable attributes, and just plain doesn't make much sense. So, use strict_strtoul(), which was created for this purpose. The store functions will treat a value of 0 as false, non-zero as true, and return -EINVAL for a parse failure. Additionally, is_enabled_store() and msi_bus_store() return -EPERM if CAP_SYS_ADMIN is lacking, rather than silently doing nothing. This is more typical behavior for sysfs attributes that need a capability. And msi_bus_store() will only print the "forced subordinate bus ..." warning if the MSI flag was actually forced to a different value.
