2009-03-20PCI/ACPI: move _OSC code to pci_root.cKenji Kaneshige
Move PCI _OSC management code from drivers/pci/pci-acpi.c to drivers/acpi/pci_root.c. The benefits are - We no longer need struct osc_data and its management code (contents are moved to struct acpi_pci_root). This simplify the code, and we no longer care about kmalloc() failure. - We can make pci_acpi_osc_support() be a static function, which is called only from drivers/acpi/pci_root.c.

Convert usages of pr_debug to dev_dbg and add physical slot name. Note that we use dev_dbg on the struct pci_bus and still manually print out the PCI slot number (instead of calling dev_dbg on a pci_dev) because a struct pci_bus with empty physical slots will not have any pci_devs. Reviewed-by: Andrew Patterson <andrew.patterson@hp.com> Signed-off-by: Alex Chiang <achiang@hp.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>

2009-03-20PCI: pciehp: enable software notification on empty slotsKenji Kaneshige
Current pciehp disables software notification of adapter presence changed event and MRL changed event when slot is turned off. Because of this, there is no way to detect those events on empty slots in the current pciehp implementation. According to the past discussion(*), this behavior was introduced to prevent endless loop that could happen if pcie_isr() runs after power fault is detected on a certain platform whose stickey power-fault bit remains on till the slot is powered on again. (*) http://sourceforge.net/mailarchive/message.php?msg_id=20051130135409.A14918%40unix-os.sc.intel.com I think this endless loop can be avoided using one bit flag that indicates power fault had been detected, instead of disabling software notification of adapter present changed event and MRL changed event. With this patch, we can enable software notification mechanism of presence changed and MRL changed event on the empty slots again.

Fix possible endless loop in pcie_isr. Currently, pcie_isr() (interrupt service routine of pciehp) can end up in an endless loop if the Slot Status register is set again immediately after being cleared.

2009-03-20PCI/MSI: Use #ifdefs instead of weak functionsMichael Ellerman
Weak functions aren't all they're cracked up to be. They lead to incorrect binaries with some toolchains, they require us to have empty functions we otherwise wouldn't, and the unused code is not elided (as of gcc 4.3.2 anyway). So replace the weak MSI arch hooks with the #define foo foo idiom. We no longer need empty versions of arch_setup/teardown_msi_irq(). This is less source (by 1 line!), and results in smaller binaries too: text data bss dec hex filename 9354300 1693916 678424 11726640 b2ef30 build/powerpc/vmlinux-before 9354052 1693852 678424 11726328 b2edf8 build/powerpc/vmlinux-after Also smaller on x86_64 and arm (iop13xx).

2009-03-20PCI/PCIe portdrv: Fix allocation of interruptsRafael J. Wysocki
If MSI-X interrupt mode is used by the PCI Express port driver, too many vectors are allocated and it is not ensured that the right vectors will be used for the right services. Namely, the PCI Express specification states that both PCI Express native PME and PCI Express hotplug will always use the same MSI or MSI-X message for signalling interrupts, which implies that the same vector will be used by both of them. Also, the VC service does not use interrupts at all. Moreover, is not clear which of the vectors allocated by pci_enable_msix() in the current code will be used for PME and hotplug and which of them will be used for AER if all of these services are configured. For these reasons, rework the allocation of interrupts for PCI Express ports so that if MSI-X are enabled, the right vectors will be used for the right purposes. Signed-off-by: Rafael J.

2009-03-20PCI: PCIe portdrv: Remove struct pcie_port_service_idRafael J. Wysocki
The PCI Express port driver uses 'struct pcie_port_service_id' for matching port service devices and drivers, but this structure contains fields that duplicate information from the port device itself (vendor, device, subvendor, subdevice) and fields that are not used by any existing port service driver (class, class_mask, drvier_data). Also, both existing port service drivers (AER and PCIe HP) don't even use the vendor and device fields for device matching. Therefore 'struct pcie_port_service_id' can be removed altogether and the only useful members of it (port_type, service) can be introduced directly into the port service device and port service driver structures. That simplifies the code quite a bit and reduces its size. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>

2009-03-20PCI: PCIe portdrv: Do not enable port device before setting up interruptsRafael J. Wysocki
The PCI Express port driver calls pci_enable_device() before setting up interrupts, which is wrong, because if there is an interrupt pin configured for the port, pci_enable_device() will likely set up an interrupt link for it. However, this shouldn't be done if either MSI or MSI-X interrupt mode is chosen for the port. The solution is to call pci_enable_device() after setting up interrupts, because in that case the interrupt link won't be set up if MSI or MSI-X are enabled. Signed-off-by: Rafael J.

2009-03-20PCI: PCIe portdrv: Aviod using service devices with wrong interruptsRafael J. Wysocki
The PCI Express port driver should not attempt to register service devices that require the ability to generate interrupts if generating interrupts is not possible. Namely, if the port has no interrupt pin configured and we cannot set up MSI or MSI-X for it, there is no way it can generate interrupts and in such a case the port services that rely on interrupts (PME, PCIe HP, AER) should not be enabled for it.

2009-03-20PCI/x86: make early dump handle multi-function devicesBjorn Helgaas
The early "dump PCI config space" code skips many multi-function devices. This patch fixes that, so it dumps all devices in PCI domain 0. We should not skip the rest of the functions if CLASS_REVISION is 0xffffffff. Often multi-function devices have gaps in the function ID space, e.g., 1c.0 and 1c.2 exist but 1c.1 doesn't. The CLASS_REVISION of the non-existent 1c.1 function will appear to be 0xffffffff. We should only look at the HEADER_TYPE of function zero. Often the "multi-function" is set in function zero, but not in other functions. Signed-off-by: Bjorn Helgaas <bjorn.helgaas@hp.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>

This patch (as1225) fixes a bug in ehci-hcd. The condition for whether unlinked QHs can become IDLE should not be that the controller is halted, but rather that the controller isn't running. In other words when the root hub is suspended, the hardware doesn't own any QHs. This fixes a problem that can show up during hibernation: If a QH is only partially unlinked when the root hub is frozen, then when the root hub is thawed the QH won't be in the IDLE state. As a result it can't be used properly for new URB submissions.
