2017-03-30PCI: Apply Cavium ACS quirk only to CN81xx/CN83xx/CN88xx devicesManish Jaggi1-0/+3
Only apply the Cavium ACS quirk to devices with ID in the range 0xa000-0xa0ff. These are the on-chip PCI devices for CN81xx/CN83xx/CN88xx.

2017-03-29PCI: Short-circuit pci_device_is_present() for disconnected devicesKeith Busch1-0/+2
If the PCI device is disconnected, return false immediately from pci_device_is_present(). pci_device_is_present() uses the bus accessors, so the early return in the device accessors doesn't help here.

2017-03-29PCI: Don't attempt config access to disconnected devicesKeith Busch1-0/+18
If we've detected the PCI device is disconnected, there is no need to attempt to access its config space since we know the operation will fail. Make all the config reads and writes return -ENODEV error immediately when in such a state. If a caller requests a config read to a disconnected device, return a data value of all 1's. This is the same as what hardware is expected to return when accessing a removed device, but software can do this faster without relying on hardware.

Add a new state to pci_dev to be set when it is unexpectedly disconnected. The PCI driver tear down functions can observe this new device state so they may skip operations that will fail. The pciehp and pcie-dpc drivers are aware when the link is down, so these set the flag when their handlers detect the device is disconnected.

2017-03-25PCI: mvebu: Avoid changing the SCC bit in the Link Status registerRussell King1-2/+3
It seems on later Armada 38x, the slot clock configuration bit is not read-only, but can be written. This means that our RW1C protection ends up clearing this bit when the link control register is written. Adjust the mask so that we only avoid writing '1' bits to the RW1C bits of this register (bits 15 and 14 of the link status) rather than masking out all the status register bits.

2017-03-24PCI: faraday: Add Faraday Technology FTPCI100 PCI Host Bridge driverLinus Walleij3-0/+569
Add a host bridge driver for the Faraday Technology FPPCI100 host bridge, used for Cortina Systems Gemini SoC (SL3516) PCI Host Bridge. This code is inspired by the out-of-tree OpenWRT patch and then extensively rewritten for device tree and using the modern helpers to cut down and modernize the code to all new PCI frameworks. A driver exists in U-Boot as well.

hv_pci_devices_present() is called in hv_pci_remove() when we remove a PCI device from the host, e.g., by disabling SR-IOV on a device. In hv_pci_remove(), the bus is already removed before the call, so we don't need to rescan the bus in the workqueue scheduled from hv_pci_devices_present(). By introducing bus state hv_pcibus_removed, we can avoid this situation.

2017-03-16PCI: iproc: Add PCI_DOMAIN dependency to PCI KconfigJon Mason1-1/+1
2+ PCI devices fail to be discovered due to each bus having the same PCI domain. This is because the domain defined in the device tree file is not being added due to PCI_DOMAIN not being enabled. So, every PCI bus has a domain of zero. When PCI_DOMAIN is selected by the Kconfig, it picks up the domain defined in the device tree file and everything works as expected. Since both PCIE_IPROC_PLATFORM and PCIE_IPROC_BCMA need PCI_DOMAIN, move it to PCIE_IPROC so it will be automatically selected for both.

2017-03-06MicroSemi Switchtec management interface driverLogan Gunthorpe6-0/+1030
Microsemi's "Switchtec" line of PCI switch devices is already well supported by the kernel with standard PCI switch drivers. However, the Switchtec device advertises a special management endpoint with a separate PCI function address and class code. This endpoint enables some additional functionality which includes: * Packet and Byte Counters * Switch Firmware Upgrades * Event and Error logs * Querying port link status * Custom user firmware commands Add a switchtec kernel module which provides PCI driver that exposes a char device. The char device provides userspace access to this interface through read, write and (optionally) poll calls. A userspace tool and library which utilizes this interface is available at [1]. This tool takes inspiration (and borrows some code) from nvme-cli [2]. The tool is largely complete at this time but additional features may be added in the future.
