2017-12-12PCI: layerscape: Change default error response behaviorMinghuan Lian
[modify to adapt to 4.9, pcie have member pp instead of pci] By default, when the PCIe controller experiences an erroneous completion from an external completer for its outbound non-posted request, it sends an OKAY response to the device's internal AXI slave system interface. However, this default system error response behavior cannot be used for other types of outbound non-posted requests. For example, the outbound memory read transaction requires an actual ERROR response, like UR completion or completion timeout. Fix this by forwarding the error response of the non-posted request.

2017-11-15PCI: mvebu: Handle changes to the bridge windows while enabledJason Gunthorpe
[ Upstream commit d9bf28e2650fe3eeefed7e34841aea07d10c6543 ] The PCI core will write to the bridge window config multiple times while they are enabled. This can lead to mbus failures like this: mvebu_mbus: cannot add window '4:e8', conflicts with another window mvebu-pcie mbus:pex@e0000000: Could not create MBus window at [mem 0xe0000000-0xe00fffff]: -22 For me this is happening during a hotplug cycle. The PCI core is not changing the values, just writing them twice while active. The patch addresses the general case of any change to an active window, but not atomically. The code is slightly refactored so io and mem can share more of the window logic.

2017-07-27PCI: rockchip: Use normal register bank for config accessorsShawn Lin
commit dc8cca5ef25ac4cb0dfc37467521a759767ff361 upstream. Rockchip's RC has two banks of registers for the root port: a normal bank that is strictly compatible with the PCIe spec, and a privileged bank that can be used to change RO bits of root port registers. When probing the RC driver, we use the privileged bank to do some basic setup work as some RO bits are hw-inited to wrong value. But we didn't change to the normal bank after probing the driver. This leads to a serious problem when the PME code tries to clear the PME status by writing PCI_EXP_RTSTA_PME to the register of PCI_EXP_RTSTA. Per PCIe 3.0 spec, section 7.8.14, the PME status bit is RW1C. So the PME code is doing the right thing to clear the PME status but we find the RC doesn't clear it but actually setting it to one. So finally the system trap in pcie_pme_work_fn() as PCI_EXP_RTSTA_PME is true now forever. This issue can be reproduced by booting kernel with pci=nomsi. Use the normal register bank for the PCI config accessors. The privileged bank is used only internally by this driver.

commit 6e347b5e05ea2ac4ac467a5a1cfaebb2c7f06f80 upstream. The host bridge memory window resource is inserted into the iomem_resource tree and cannot be deallocated until the host bridge itself is removed. Previously, the window was on the stack, which meant the iomem_resource entry pointed into the stack and was corrupted as soon as the probe function returned, which caused memory corruption and errors like this: pcie_iproc_bcma bcma0:8: resource collision: [mem 0x40000000-0x47ffffff] conflicts with PCIe MEM space [mem 0x40000000-0x47ffffff] Move the memory window resource from the stack into struct iproc_pcie so its lifetime matches that of the host bridge.

commit 60e2e2fbafdd1285ae1b4ad39ded41603e0c74d0 upstream. The devfn of 00:02.0 is 0x10. devfn_to_wslot(0x10) == 0x2, and wslot_to_devfn(0x2) should be 0x10, while it's 0x2 in the current code. Due to this, hv_eject_device_work() -> pci_get_domain_bus_and_slot() returns NULL and pci_stop_and_remove_bus_device() is not called. Later when the real device driver's .remove() is invoked by hv_pci_remove() -> pci_stop_root_bus(), some warnings can be noticed because the VM has lost the access to the underlying device at that time.

2016-10-12PCI: hisi: Reorder struct hisi_pcieBjorn Helgaas
Reorder struct hisi_pcie to put generic fields first. No functional change intended. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
2016-10-12PCI: hisi: Pass device-specific struct to internal functionsBjorn Helgaas
Only interfaces used from outside the driver, e.g., those called by the DesignWare core, need to accept pointers to the generic struct pcie_port. Internal interfaces can accept pointers to the device-specific struct, which makes them more straightforward. No functional change intended. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
2016-10-12PCI: hisi: Include register block base in PCIE_SYS_STATE4 addressBjorn Helgaas
Include the PCIE_HIP06_CTRL_OFF block base in the PCIE_SYS_STATE4 register address so reads of PCIE_SYS_STATE4 don't have to mention both. No functional change intended. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>

2016-10-12PCI: xilinx-nwl: Remove unused platform dataBjorn Helgaas
The xilinx-nwl driver never uses the platform drvdata pointer, so don't bother setting it. No functional change intended. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
2016-10-12PCI: xilinx-nwl: Add local struct device pointersBjorn Helgaas
Use a local "struct device *dev" for brevity and consistency with other drivers. No functional change intended. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
2016-10-12PCI: xilinx: Removed unused xilinx_pcie_assign_msi() argumentBjorn Helgaas
xilinx_pcie_assign_msi() doesn't use the struct xilinx_pcie_port pointer passed to it, so remove the argument completely. No functional change intended. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>

Add device-specific register accessors for consistency across host drivers. No functional change intended. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
2016-10-12PCI: xgene: Pass struct xgene_pcie_port to setup functionsBjorn Helgaas
Pass the struct xgene_pcie_port pointer, not addresses, to setup functions. This enables future simplifications. No functional change intended. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
