Enable Configuration RRS SV, which makes device readiness visible, early instead of during child bus scanning (Bjorn Helgaas) - Log debug messages about reset methods being used (Bjorn Helgaas) - Avoid reset when it has been disabled via sysfs (Nishanth Aravamudan) - Add common pci-ep-bus.yaml schema for exporting several peripherals of a single PCI function via devicetree (Andrea della Porta) - Create DT nodes for PCI host bridges to enable loading device tree overlays to create platform devices for PCI devices that have several features that require multiple drivers (Herve Codina) Resource management: - Enlarge devres table[] to accommodate bridge windows, ROM, IOV BARs, etc., and validate BAR index in devres interfaces (Philipp Stanner) - Fix typo that repeatedly distributed resources to a bridge instead of iterating over subordinate bridges, which resulted in too little space to assign some BARs (Kai-Heng Feng) - Relax bridge window tail sizing for optional resources, e.g., IOV BARs, to avoid failures when removing and re-adding devices (Ilpo Järvinen) - Allow drivers to enable devices even if we haven't assigned optional IOV resources to them (Ilpo Järvinen) - Rework handling of optional resources (IOV BARs, ROMs) to reduce failures if we can't allocate them (Ilpo Järvinen) - Fix a NULL dereference in the SR-IOV VF creation error path (Shay Drory) - Fix s390 mmio_read/write syscalls, which didn't cause page faults in some cases, which broke vfio-pci lazy mapping on first access (Niklas Schnelle) - Add pdev->non_mappable_bars to replace CONFIG_VFIO_PCI_MMAP, which was disabled only for s390 (Niklas Schnelle) - Support mmap of PCI resources on s390 except for ISM devices (Niklas Schnelle) ASPM: - Delay pcie_link_state deallocation to avoid dangling pointers that cause invalid references during hot-unplug (Daniel Stodden) Power management: - Allow PCI bridges to go to D3Hot when suspending on all non-x86 systems (Manivannan Sadhasivam) Power control: - Create pwrctrl devices in pci_scan_device() to make it more symmetric with pci_pwrctrl_unregister() and make pwrctrl devices for PCI bridges possible (Manivannan Sadhasivam) - Unregister pwrctrl devices in pci_destroy_dev() so DOE, ASPM, etc. can still access devices after pci_stop_dev() (Manivannan Sadhasivam) - If there's a pwrctrl device for a PCI device, skip scanning it because the pwrctrl core will rescan the bus after the device is powered on (Manivannan Sadhasivam) - Add a pwrctrl driver for PCI slots based on voltage regulators described via devicetree (Manivannan Sadhasivam) Bandwidth control: - Add set_pcie_speed.sh to TEST_PROGS to fix issue when executing the set_pcie_cooling_state.sh test case (Yi Lai) - Avoid a NULL pointer dereference when we run out of bus numbers to assign for a bridge secondary bus (Lukas Wunner) Hotplug: - Drop superfluous pci_hotplug_slot_list, try_module_get() calls, and NULL pointer checks (Lukas Wunner) - Drop shpchp module init/exit logging, replace shpchp dbg() with ctrl_dbg(), and remove unused dbg(), err(), info(), warn() wrappers (Ilpo Järvinen) - Drop 'shpchp_debug' module parameter in favor of standard dynamic debugging (Ilpo Järvinen) - Drop unused cpcihp .get_power(), .set_power() function pointers (Guilherme Giacomo Simoes) - Disable hotplug interrupts in portdrv only when pciehp is not enabled to avoid issuing two hotplug commands too close together (Feng Tang) - Skip pciehp 'device replaced' check if the device has been removed to address a deadlock when resuming after a device was removed during system sleep (Lukas Wunner) - Don't enable pciehp hotplug interupt when resuming in poll mode (Ilpo Järvinen) Virtualization: - Fix bugs in 'pci=config_acs=' kernel command line parameter (Tushar Dave) DOE: - Expose supported DOE features via sysfs (Alistair Francis) - Allow DOE support to be enabled even if CXL isn't enabled (Alistair Francis) Endpoint framework: - Convert PCI device data so pci-epf-test works correctly on big-endian endpoint systems (Niklas Cassel) - Add BAR_RESIZABLE type to endpoint framework and add DWC core support for EPF drivers to set BAR_RESIZABLE type and size (Niklas Cassel) - Fix pci-epf-test double free that causes an oops if the host reboots and PERST# deassertion restarts endpoint BAR allocation (Christian Bruel) - Fix endpoint BAR testing so tests can skip disabled BARs instead of reporting them as failures (Niklas Cassel) - Widen endpoint test BAR size variable to accommodate BARs larger than INT_MAX (Niklas Cassel) - Remove unused tools 'pci' build target left over after moving tests to tools/testing/selftests/pci_endpoint (Jianfeng Liu) Altera PCIe controller driver: -

Add BCM2712 support and DT updates (Stanimir Varbanov) - Apply link speed restriction before bringing link up, not after (Jim Quinlan) - Update Max Link Speed in Link Capabilities via the internal writable register, not the read-only config register (Jim Quinlan) - Handle regulator_bulk_get() error to avoid panic when we call regulator_bulk_free() later (Jim Quinlan) - Disable regulators only when removing the bus immediately below a Root Port because we don't support regulators deeper in the hierarchy (Jim Quinlan) - Make const read-only arrays static (Colin Ian King) Cadence PCIe endpoint driver: - Correct MSG TLP generation so endpoints can generate INTx messages (Hans Zhang) Freescale i.MX6 PCIe controller driver: - Identify the second controller on i.MX8MQ based on devicetree 'linux,pci-domain' instead of DBI 'reg' address (Richard Zhu) - Remove imx_pcie_cpu_addr_fixup() since dwc core can now derive the ATU input address (using parent_bus_offset) from devicetree (Frank Li) Freescale Layerscape PCIe controller driver: - Drop deprecated 'num-ib-windows' and 'num-ob-windows' and unnecessary 'status' from example (Krzysztof Kozlowski) - Correct the syscon_regmap_lookup_by_phandle_args("fsl,pcie-scfg") arg_count to fix probe failure on LS1043A (Ioana Ciornei) HiSilicon STB PCIe controller driver: - Call phy_exit() to clean up if histb_pcie_probe() fails (Christophe JAILLET) Intel Gateway PCIe controller driver: - Remove intel_pcie_cpu_addr() since dwc core can now derive the ATU input address (using parent_bus_offset) from devicetree (Frank Li) Intel VMD host bridge driver: - Convert vmd_dev.cfg_lock from spinlock_t to raw_spinlock_t so pci_ops.read() will never sleep, even on PREEMPT_RT where spinlock_t becomes a sleepable lock, to avoid calling a sleeping function from invalid context (Ryo Takakura) MediaTek PCIe Gen3 controller driver: - Remove leftover mac_reset assert for Airoha EN7581 SoC (Lorenzo Bianconi) - Add EN7581 PBUS controller 'mediatek,pbus-csr' DT property and program host bridge memory aperture to this syscon node (Lorenzo Bianconi) Qualcomm PCIe controller driver: -
