PCI: shpchp: Enable bridge bus mastering if MSI is enabled

2017-11-26T13:51:01Z

commit 48b79a14505349a29b3e20f03619ada9b33c4b17 upstream. An SHPC may generate MSIs to notify software about slot or controller events (SHPC spec r1.0, sec 4.7). A PCI device can only generate an MSI if it has bus mastering enabled. Enable bus mastering if the bridge contains an SHPC that uses MSI for event notifications.

PCI hotplug: shpchp: don't blindly claim non-AMD 0x7450 device IDs

2011-11-14T17:43:14Z

Previously we claimed device ID 0x7450, regardless of the vendor, which is clearly wrong. Now we'll claim that device ID only for AMD. I suspect this was just a typo in the original code, but it's possible this change will break shpchp on non-7450 AMD bridges. If so, we'll have to fix them as we find them.

shpchp: update workqueue usage

2010-10-18T06:33:02Z

* Rename shpchp_wq to shpchp_ordered_wq and add non-ordered shpchp_wq which is used instead of the system workqueue. This is to remove the use of flush_scheduled_work() which is deprecated and scheduled for removal. * With cmwq in place, there's no point in creating workqueues lazily. Create both shpchp_wq and shpchp_ordered_wq upfront. * Include workqueue.h from shpchp.h. Signed-off-by: Tejun Heo Acked-by: Jesse Barnes

PCI: hotplug/shpchp_hpc: add parenthesis in SLOT_REG_RSVDZ_MASK

2010-07-30T16:29:10Z

The SLOT_REG_RSVDZ_MASK macro is normally used like this: slot_reg &= ~SLOT_REG_RSVDZ_MASK; The ~ operator has higher precedence than the | operator from inside the macro, so it needs parenthesis. Reviewed-by: Kenji Kaneshige Signed-off-by: Dan Carpenter Signed-off-by: Jesse Barnes

PCI: Make current and maximum bus speeds part of the PCI core

2010-02-23T00:15:17Z

Move the max_bus_speed and cur_bus_speed into the pci_bus. Expose the values through the PCI slot driver instead of the hotplug slot driver. Update all the hotplug drivers to use the pci_bus instead of their own data structures. Signed-off-by: Matthew Wilcox Signed-off-by: Jesse Barnes

PCI hotplug: shpchp: message refinement

2008-10-23T23:14:00Z

This patch refines messages in shpchp module. The main changes are as follows: - remove the trailing "." - remove __func__ as much as possible - capitalize the first letter of messages - show PCI device address including its domain Signed-off-by: Taku Izumi Signed-off-by: Jesse Barnes

shpchp: check firmware before taking control

2008-06-10T17:59:53Z

Fix the following problems of shpchp driver about getting hotplug control from firmware. - The shpchp driver must not control the hotplug controller if it fails to get control from the firmware. But current shpchp controls the hotplug controller regardless the result, because it doesn't check the return value of get_hp_hw_control_from_firmware(). - Current shpchp driver doesn't support _OSC. The pciehp driver already have the code for evaluating _OSC and OSHP and shpchp and pciehp can share it. So this patch move that code from pciehp to acpi_pcihp.c.
