-0500) ---------------------------------------------------------------- Enumeration: - Add locking to read/modify/write PCIe Capability Register accessors for Link Control and Root Control - Use pci_dev_id() when possible instead of manually composing ID from dev->bus->number and dev->devfn Resource management: - Move prototypes for __weak sysfs resource files to linux/pci.h to fix "no previous prototype" warnings - Make more I/O port accesses depend on HAS_IOPORT - Use devm_platform_get_and_ioremap_resource() instead of open-coding platform_get_resource() followed by devm_ioremap_resource() Power management: - Ensure devices are powered up while accessing VPD - If device is powered-up, keep it that way while polling for PME - Only read PCI_PM_CTRL register when available, to avoid reading the wrong register and corrupting dev->current_state Virtualization: - Avoid Secondary Bus Reset on NVIDIA T4 GPUs Error handling: - Remove unused pci_disable_pcie_error_reporting() - Unexport pci_enable_pcie_error_reporting(), used only by aer.c - Unexport pcie_port_bus_type, used only by PCI core VGA: - Simplify and clean up typos in VGA arbiter Apple PCIe controller driver: - Initialize pcie->nvecs (number of available MSIs) before use Broadcom iProc PCIe controller driver: - Use of_property_read_bool() instead of low-level accessors for boolean properties Broadcom STB PCIe controller driver: - Assert PERST# when probing BCM2711 because some bootloaders don't do it Freescale i.MX6 PCIe controller driver: - Add .host_deinit() callback so we can clean up things like regulators on probe failure or driver unload Freescale Layerscape PCIe controller driver: - Add support for link-down notification so the endpoint driver can process LINK_DOWN events - Add suspend/resume support, including manual PME_Turn_off/PME_TO_Ack handshake - Save Link Capabilities during probe so they can be restored when handling a link-up event, since the controller loses the Link Width and Link Speed values during reset Intel VMD host bridge driver: - Fix disable of bridge windows during domain reset; previously we cleared the base/limit registers, which actually left the windows enabled Marvell MVEBU PCIe controller driver: - Remove unused busn member Microchip PolarFlare PCIe controller driver: - Fix interrupt bit definitions so the SEC and DED interrupt handlers work correctly - Make driver buildable as a module - Read FPGA MSI configuration parameters from hardware instead of hard-coding them Microsoft Hyper-V host bridge driver: - To avoid a NULL pointer dereference, skip MSI restore after hibernate if MSI/MSI-X hasn't been enabled NVIDIA Tegra194 PCIe controller driver: - Revert "PCI: tegra194: Enable support for 256 Byte payload" because Linux doesn't know how to reduce MPS from to 256 to 128 bytes for Endpoints below a Switch (because other devices below the Switch might already be operating), which leads to Malformed TLP errors Qualcomm PCIe controller driver: - Add DT and driver support for interconnect bandwidth voting for "pcie-mem" and "cpu-pcie" interconnects - Fix broken SDX65 "compatible" DT property - Configure controller so MHI bus master clock will be switched off while in ASPM L1.x states - Use alignment restriction from EPF core in EPF MHI driver - Add Endpoint eDMA support - Add MHI eDMA support - Add Snapdragon SM8450 support to the EPF MHI driversupport - Add MHI eDMA support - Add Snapdragon SM8450 support to the EPF MHI driversupport - Add MHI eDMA support - Add Snapdragon SM8450 support to the EPF MHI driversupport - Add MHI eDMA support - Add Snapdragon SM8450 support to the EPF MHI driver - Use iATU for EPF MHI transfers smaller than 4K to avoid eDMA setup latency - Add sa8775p DT binding and driver support Rockchip PCIe controller driver: - Use 64-bit mask on MSI 64-bit PCI address to avoid zeroing out the upper 32 bits SiFive FU740 PCIe controller driver: - Set the supported number of MSI vectors so we can use all available MSI interrupts Synopsys DesignWare PCIe controller driver: - Add generic dwc suspend/resume APIs (dw_pcie_suspend_noirq() and dw_pcie_resume_noirq()) to be called by controller driver suspend/resume ops, and a controller callback to send PME_Turn_Off MicroSemi Switchtec management driver: - Add support for PCIe Gen5 devices Miscellaneous: - Reorder and compress to reduce size of struct pci_dev - Fix race in DOE destroy_work_on_stack() - Add stubs to avoid casts between incompatible function types - Explicitly include correct DT includes to untangle headers ---------------------------------------------------------------- Alex Williamson (2): PCI/VPD: Add runtime power management to sysfs interface PCI: Fix runtime
