Make pci_stop_dev() and pci_destroy_dev() safe so concurrent callers can't stop a device multiple times, even as we migrate from the global pci_rescan_remove_lock to finer-grained locking (Keith Busch) - Improve pci_walk_bus() implementation by making it recursive and moving locking up to avoid need for a 'locked' parameter (Keith Busch) - Unexport pci_walk_bus_locked(), which is only used internally by the PCI core (Keith Busch) - Detect some Thunderbolt chips that are built-in and hence 'trustworthy' by a heuristic since the 'ExternalFacingPort' and 'usb4-host-interface' ACPI properties are not quite enough (Esther Shimanovich) Resource management: - Use PCI bus addresses (not CPU addresses) in 'ranges' properties when building dynamic DT nodes so systems where PCI and CPU addresses differ work correctly (Andrea della Porta) - Tidy resource sizing and assignment with helpers to reduce redundancy (Ilpo Järvinen) - Improve pdev_sort_resources() 'bogus alignment' warning to be more specific (Ilpo Järvinen) Driver binding: - Convert driver .remove_new() callbacks to .remove() again to finish the conversion from returning 'int' to being 'void' (Sergio Paracuellos) - Export pcim_request_all_regions(), a managed interface to request all BARs (Philipp Stanner) - Replace pcim_iomap_regions_request_all() with pcim_request_all_regions(), and pcim_iomap_table()[n] with pcim_iomap(n), in the following drivers: ahci, crypto qat, crypto octeontx2, intel_th, iwlwifi, ntb idt, serial rp2, ALSA korg1212 (Philipp Stanner) - Remove the now unused pcim_iomap_regions_request_all() (Philipp Stanner) - Export pcim_iounmap_region(), a managed interface to unmap and release a PCI BAR (Philipp Stanner) - Replace pcim_iomap_regions(mask) with pcim_iomap_region(n), and pcim_iounmap_regions(mask) with pcim_iounmap_region(n), in the following drivers: fpga dfl-pci, block mtip32xx, gpio-merrifield, cavium (Philipp Stanner) Error handling: - Add sysfs 'reset_subordinate' to reset the entire hierarchy below a bridge; previously Secondary Bus Reset could only be used when there was a single device below a bridge (Keith Busch) - Warn if we reset a running device where the driver didn't register pci_error_handlers notification callbacks (Keith Busch) ASPM: - Disable ASPM L1 before touching L1 PM Substates to follow the spec closer and avoid a CPU load timeout on some platforms (Ajay Agarwal) - Set devices below Intel VMD to D0 before enabling ASPM L1 Substates as required per spec for all L1 Substates changes (Jian-Hong Pan) Power management: - Enable starfive controller runtime PM before probing host bridge (Mayank Rana) - Enable runtime power management for host bridges (Krishna chaitanya chundru) Power control: - Use of_platform_device_create() instead of of_platform_populate() to create pwrctl platform devices so we can control it based on the child nodes (Manivannan Sadhasivam) - Create pwrctrl platform devices only if there's a relevant power supply property (Manivannan Sadhasivam) - Add device link from the pwrctl supplier to the PCI dev to ensure pwrctl drivers are probed before the PCI dev driver; this avoids a race where pwrctl could change device power state while the PCI driver was active (Manivannan Sadhasivam) - Find pwrctl device for removal with of_find_device_by_node() instead of searching all children of the parent (Manivannan Sadhasivam) - Rename 'pwrctl' to 'pwrctrl' to match new bandwidth controller ('bwctrl') and hotplug files (Bjorn Helgaas) Bandwidth control: - Add read/modify/write locking for Link Control 2, which is used to manage Link speed (Ilpo Järvinen) - Extract Link Bandwidth Management Status check into pcie_lbms_seen(), where it can be shared between the bandwidth controller and quirks that use it to help retrain failed links (Ilpo Järvinen) - Re-add Link Bandwidth notification support with updates to address the reasons it was previously reverted (Alexandru Gagniuc, Ilpo Järvinen) - Add pcie_set_target_speed() and related functionality so drivers can manage PCIe Link speed based on thermal or other constraints (Ilpo Järvinen) - Add a thermal cooling driver to throttle PCIe Links via the existing thermal management framework (Ilpo Järvinen) - Add a userspace selftest for the PCIe bandwidth controller (Ilpo Järvinen) PCI device hotplug: - Add hotplug controller driver for Marvell OCTEON multi-function device where function 0 has a management console interface to enable/disable and provision various personalities for the other functions (Shijith Thotton) - Retain a reference to the pci_bus for the lifetime of a pci_slot to avoid a use-after-free when the thunderbolt driver resets USB4 host routers on boot, causing hotplug remove/add of downstream docks or other devices (Lukas Wunner) - Remove unused cpcihp struct cpci_hp_controller_ops.hardware_test (Guilherme Giacomo Simoes) - Remove unused cpqphp struct ctrl_dbg.ctrl (Christophe JAILLET) - Use pci_bus_read_dev_vendor_id() instead of hand-coded presence detection in cpqphp (Ilpo Järvinen) - Simplify cpqphp enumeration, which is already simple-minded and doesn't handle devices below hot-added bridges (Ilpo Järvinen) Virtualization: - Add ACS quirk for Wangxun FF5xxx NICs, which don't advertise an ACS capability but do isolate functions as though PCI_ACS_RR and PCI_ACS_CR were set, so the functions can be in independent IOMMU groups (Mengyuan Lou) TLP Processing Hints (TPH): - Add and document TLP Processing Hints (TPH) support so drivers can enable and disable TPH and the kernel can save/restore TPH configuration (Wei Huang) - Add TPH Steering Tag support so drivers can retrieve Steering Tag values associated with specific CPUs via an ACPI _DSM to improve performance by directing DMA writes closer to their consumers (Wei Huang) Data Object Exchange (DOE): - Wait up to 1 second for DOE Busy bit to clear before writing a request to the mailbox to avoid failures if the mailbox is still busy from a previous transfer (Gregory Price) Endpoint framework: - Skip attempts to allocate from endpoint controller memory window if the requested size is larger than the window (Damien Le Moal) - Add and document pci_epc_mem_map() and pci_epc_mem_unmap() to handle controller-specific size and alignment constraints, and add test cases to the endpoint test driver (Damien Le Moal) - Implement dwc pci_epc_ops.align_addr() so pci_epc_mem_map() can observe DWC-specific alignment requirements (Damien Le Moal) - Synchronously cancel command handler work in endpoint test before cleaning up DMA and BARs (Damien Le Moal) - Respect endpoint page size in dw_pcie_ep_align_addr() (Niklas Cassel) - Use dw_pcie_ep_align_addr() in dw_pcie_ep_raise_msi_irq() and dw_pcie_ep_raise_msix_irq() instead of open coding the equivalent (Niklas Cassel) - Avoid NULL dereference if Modem Host Interface Endpoint lacks 'mmio' DT property (Zhongqiu Han) - Release PCI domain ID of Endpoint controller parent (not controller itself) and before unregistering the controller, to avoid use-after-free (Zijun Hu) - Clear secondary (not primary) EPC in pci_epc_remove_epf() when removing the secondary controller associated with an NTB (Zijun Hu) Cadence PCIe controller driver: - Lower severity of 'phy-names' message (Bartosz Wawrzyniak) Freescale i.MX6 PCIe controller driver: - Fix suspend/resume support on i.MX6QDL, which has a hardware erratum that prevents use of L2 (Stefan Eichenberger) Intel VMD host bridge driver: - Add 0xb60b and 0xb06f Device IDs for client SKUs (Nirmal Patel) MediaTek PCIe Gen3 controller driver: - Update mediatek-gen3 DT binding to require the exact number of clocks for each SoC (Fei Shao) - Add support for DT 'max-link-speed' and 'num-lanes' properties to restrict the link speed and width (AngeloGioacchino Del Regno) Microchip PolarFlare PCIe controller driver: - Add DT and driver support for using either of the two PolarFire Root Ports (Conor Dooley) NVIDIA Tegra194 PCIe controller driver: - Move endpoint controller cleanups that depend on refclk from the host to the notifier that tells us the host has deasserted PERST#, when refclk should be valid (Manivannan Sadhasivam) Qualcomm PCIe controller driver: - Add qcom SAR2130P DT binding with an additional clock (Dmitry Baryshkov) - Enable MSI interrupts if 'global' IRQ is supported, since a previous commit unintentionally masked them (Manivannan Sadhasivam) - Move endpoint controller cleanups that depend on refclk from the host to the notifier that tells us the host has deasserted PERST#, when refclk should be valid (Manivannan Sadhasivam) - Add DT binding and driver support for IPQ9574, with Synopsys IP v5.80a and Qcom IP 1.27.0 (devi priya) - Move the OPP "operating-points-v2" table from the qcom,pcie-sm8450.yaml DT binding to qcom,pcie-common.yaml, where it can be used by other Qcom platforms (Qiang Yu) - Add 'global' SPI interrupt for events like link-up, link-down to qcom,pcie-x1e80100 DT binding so we can start enumeration when the link comes up (Qiang Yu) - Disable ASPM L0s for qcom,pcie-x1e80100 since the PHY is not tuned to support this (Qiang Yu) - Add ops_1_21_0 for SC8280X family SoC, which doesn't use the 'iommu-map' DT property and doesn't need BDF-to-SID translation (Qiang Yu) Rockchip PCIe controller driver: - Define ROCKCHIP_PCIE_AT_SIZE_ALIGN to replace magic 256 endpoint .align value (Damien Le Moal) - When unmapping an endpoint window, compute the region index instead of searching for it, and verify that the address was mapped (Damien Le Moal) - When mapping an endpoint window, verify that the address hasn't been mapped already (Damien Le Moal) - Implement pci_epc_ops.align_addr() for rockchip-ep (Damien Le Moal) - Fix MSI IRQ data mapping to observe the alignment constraint, which fixes intermittent page faults in memcpy_toio() and memcpy_fromio() (Damien Le Moal) - Rename rockchip_pcie_parse_ep_dt() to rockchip_pcie_ep_get_resources() for consistency with similar DT interfaces (Damien Le Moal) - Skip the unnecessary link train in rockchip_pcie_ep_probe() and do it only in the endpoint start operation (Damien Le Moal) - Implement pci_epc_ops.stop_link() to disable link training and controller configuration (Damien Le Moal) - Attempt link training at 5 GT/s when both partners support it (Damien Le Moal) - Add a handler for PERST# signal so we can detect host-initiated resets and start link training after PERST# is deasserted (Damien Le Moal) Synopsys DesignWare PCIe controller driver: - Clear outbound address on unmap so dw_pcie_find_index() won't match an ATU index that was already unmapped (Damien Le Moal) - Use of_property_present() instead of of_property_read_bool() when testing for presence of non-boolean DT properties (Rob Herring) - Advertise 1MB size if endpoint supports Resizable BARs, which was inadvertently lost in v6.11 (Niklas Cassel) TI J721E PCIe driver: - Add PCIe support for J722S SoC (Siddharth Vadapalli) - Delay PCIE_T_PVPERL_MS (100 ms), not just PCIE_T_PERST_CLK_US (100 us), before deasserting PERST# to ensure power and refclk are stable (Siddharth Vadapalli) TI Keystone PCIe controller driver: - Set the 'ti,keystone-pcie' mode so v3.65a devices work in Root Complex mode (Kishon Vijay Abraham I) - Try to avoid unrecoverable SError for attempts to issue config transactions when the link is down; this is racy but the best we can do (Kishon Vijay Abraham I) Miscellaneous: -
