* PCI: Fix pci-e port driver slot_reset bad default return valueZhang, Yanmin2009-05-05
| | | | | | | | | | | | When an upstream port reports an AER error to root port, kernel starts error recovery procedures. The default return value of function pcie_portdrv_slot_reset is PCI_ERS_RESULT_NONE. If all port service drivers of the downstream port under the upstream port have no slot_reset method in pci_error_handlers, AER recovery would stop without resume. Below patch against 2.6.30-rc3 fixes it. Signed-off-by: Zhang Yanmin <yanmin.zhang@linux.intel.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>

| | | | | | | | | | | | | | | | | pcie_port_device_remove currently calls the remove method of port drivers twice. Ouch! We are calling device_for_each_child multiple times for no apparent reason. So make it simple. Place put_device and device_unregister into remove_iter, and throw out the rest. Only call device_for_each_child once. The code is simpler and actually works!

* PCI/PCIe portdrv: Fix allocation of interruptsRafael J. Wysocki2009-03-19
| | | | | | | | | | | | | | | | | | | | | | 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.

* PCI: PCIe portdrv: Remove struct pcie_port_service_idRafael J. Wysocki2009-03-19
| | | | | | | | | | | | | | | | | | 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>

* PCI: PCIe portdrv: Do not enable port device before setting up interruptsRafael J. Wysocki2009-03-19
| | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | Commit 47a8b0cc (Enable PCIe AER only after checking firmware support) wants to walk the PCI bus in the remove path to disable AER, and calls pci_walk_bus for downstream bridges. Unfortunately, in the remove path, we remove devices and bridges in a depth-first manner, starting with the furthest downstream bridge and working our way backwards. The furthest downstream bridges will not have a dev->subordinate, and we hit a NULL deref in pci_walk_bus. Check for dev->subordinate first before attempting to walk the PCI hierarchy below us.

* PCI: Enable PCIe AER only after checking firmware supportAndrew Patterson2009-02-24
| | | | | | | | | | | | | | The PCIe port driver currently sets the PCIe AER error reporting bits for any root or switch port without first checking to see if firmware will grant control. This patch moves setting these bits to the AER service driver aer_enable_port routine. The bits are then set for the root port and any downstream switch ports after the check for firmware support (aer_osc_setup) is made.

* PCI: properly clean up ASPM link state on device removeAlex Chiang2009-02-04
| | | | | | | | | | | | | | | | | | | | | We only want to disable ASPM when the last function is removed from the parent's device list. We determine this by checking to see if the parent's device list is completely empty. Unfortunately, we never hit that code because the parent is considered an upstream port, and never had an ASPM link_state associated with it. The early check for !link_state causes us to return early, we never discover that our device list is empty, and thus we never remove the downstream ports' link_state nodes. Instead of checking to see if the parent's device list is empty, we can check to see if we are the last device on the list, and if so, then we know that we can clean up properly.

| | | | | | | | | | | | | | | | | | | | | | | The cpu_relax() function can be a noop on certain architectures like IA-64 when CPU threads are disabled, so use msleep instead during link retraining busy/wait loop. Introduce define LINK_RETRAIN_TIMEOUT instead of hard-coding timeout in pcie_aspm_configure_common_clock. Use time_after() to avoid jiffy wraparound when checking for expired timeout. After timeout expires, recheck link status register link training bit instead of checking for expired timeout to avoid possible false positive.

The scenario is that first, the PCI Express port driver calls suspend and resume routines of each port service driver from its pcie_portdrv_suspend() and pcie_portdrv_resume() callbacks, respectively (which is correct), and second, the pcie_port_bus_type driver calls them from its ->suspend() and ->resume() callbacks (which is not correct, because it doesn't happen at the right time).

* PCI: struct device - replace bus_id with dev_name(), dev_set_name()Kay Sievers2009-01-07
| | | | | | | | | | | | | | | | | | | | | | This patch is part of a larger patch series which will remove the "char bus_id[20]" name string from struct device. The device name is managed in the kobject anyway, and without any size limitation, and just needlessly copied into "struct device". To set and read the device name dev_name(dev) and dev_set_name(dev) must be used. If your code uses static kobjects, which it shouldn't do, "const char *init_name" can be used to statically provide the name the registered device should have. At registration time, the init_name field is cleared, to enforce the use of dev_name(dev) to access the device name at a later time. We need to get rid of all occurrences of bus_id in the entire tree to be able to enable the new interface. Please apply this patch, and possibly convert any remaining remaining occurrences of bus_id.

| * PCI Express ASPM support should default to 'No'Jesper Juhl2008-04-23
| | | | | | | | | | | | | | | | | | | | | | | | Running 'make oldconfig' I just noticed that PCIEASPM defaults to 'y' in Kconfig even though the feature is both experimental and the help text recommends that if you are unsure you say 'n'. It seems to me that this really should default to 'n', not 'y' at the moment. The following patch makes that change. Please consider applying.
