Merge tag 'pci-v7.3-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pciPull PCI updates from Bjorn Helgaas: "Resource management: - Add hotplug reservation only once (not at each level of the hierarchy) so bridge windows don't grow more than necessary (Ilpo Järvinen) Driver binding: - Rework device matching so device ID lifetime only needs to cover the probe path since dynamic IDs can be removed at any time (Gary Guo) Error handling: - Update mappings of AER errors to agent & layer and log them for each individual error when multiple errors detected (Lukas Wunner) - Log Error Source only once, not twice in separate messages (Lukas Wunner) - Emit TLP Log only for unmasked errors (Lukas Wunner) - Support Advisory Non-Fatal Errors (Lukas Wunner) - Allow DPC on all Downstream Ports, not just Root Ports, when OS controls AER (Darshit Shah) ASPM: - Program the same ASPM Control values for every function of multi-function devices, as recommended by the PCIe spec (Krishna Chaitanya Chundru) - Avoid L0s for Realtek RTS525A, where it causes an AER interrupt storm (Max Lee) - Avoid ASPM L0s, L1, and L1 PM Substates based on 'aspm-no-l0s', 'aspm-no-l1' [1], and 'aspm-no-l1ss' DT properties (Krishna Chaitanya Chundru) Power management: - Allow D3 for native hotplug-capable Root Ports on non-x86 platforms (we avoid D3 for these ports on x86 because some old platforms didn't validate it) (Manivannan Sadhasivam) - Allow portdrv to claim Ports even if they don't support services (AER, PME, DPC, hotplug, etc) so it can do power management (Brian Norris) Power control: - Add support for PCIe WAKE# interrupt when described via DT (Krishna Chaitanya Chundru) - For the TC9563 PCIe switch: - Take a reference on the I2C adapter to avoid uninterruptible hang when unloading an I2C module while in-use (Johan Hovold) - Update DT binding and driver to restrict Tx Amplitude, DFE and N_FTS to USP, DSP1 and DSP2 (Manivannan Sadhasivam) - Power off only external-facing ports (DSP1, DSP2), leaving USP and DSP3 (aka VDSP) powered up (Manivannan Sadhasivam) - Move integrated MAC Endpoint out of the list of internal ports and configure it separately (Manivannan Sadhasivam) Virtualization: - Add ACS quirk for Pericom PI7C9X2G608 switches (Tim Harvey) - Fix a long-standing bug in the Intel PCH Root Port MPC ACS quirk that didn't update the intended INTEL_MPC_REG_IRBNCE bit because it used a 16-bit config write when a 32-bit write was intended (Mohamad Raizudeen) Procfs: - Avoid spurious runtime PM wakeup on config space accesses that are outside config space and fail before reaching PCI (Krzysztof Wilczyński) - Warn on user-space writes to kernel-exclusive config space regions, as we already do for sysfs (Krzysztof Wilczyński) - Check credentials of opener, not reader, for config space reads, as we already do for sysfs (Krzysztof Wilczyński) Sysfs: - In pci_write_legacy_io(), avoid out-of-bounds reads from the user buffer and fix incorrect ioport write data (1-byte writes on little-endian powerpc, 2- and 4-byte writes on big-endian powerpc) (Krzysztof Wilczyński) - In pci_read_legacy_io(), fix incorrect ioport read data for 2- and 4-byte reads on big-endian powerpc (Krzysztof Wilczyński) - Fix I/O port accessor argument order in Alpha pci_legacy_write() (Krzysztof Wilczyński) - Avoid spurious runtime PM wakeup on config space accesses that are outside config space and fail before reaching PCI (Krzysztof Wilczyński) - Return -EINVAL, not -ENODEV, for mmap of I/O BAR that fails because the arch doesn't support it, as we do for procfs (Krzysztof Wilczyński) - Check for LOCKDOWN_PCI_ACCESS for legacy_io and legacy_mem, as we do for other config space accessors (Krzysztof Wilczyński) Peer-to-peer DMA: - Add Nvidia Vera Rubin to list of platforms that support P2PDMA (Leon Romanovsky) Endpoint framework: - Check doorbell SUCCESS bit in pci_endpoint_test to avoid treating some failures as successes (Niklas Cassel) - Fail doorbell test when the trigger IRQ is missed (Niklas Cassel) New native PCIe controller drivers: - Add DT binding and driver for NVIDIA Tegra264 (Thierry Reding) Native PCIe controllers: - Use common wait time definitions for PCIe link monitoring instead of defining driver-private duplicates (Thierry Reding) Generic host bridge driver: - Fix NULL pointer dereference that caused enumeration failures on 32-bit CAM systems (Steffen Persvold) Amlogic Meson PCIe controller driver: - Correct the PERST# GPIO state so it remains asserted until power and REFCLK become stable to fix enumeration failure (Ronald Claveau) ASPEED PCIe controller driver: - Switch to irq_domain_create_linear() so we can obsolete irq_domain_add_linear() (Jiri Slaby) Cadence PCIe controller driver: - Add MODULE_DEVICE_TABLE to generate module aliases for OF-based module autoloading (Pengpeng Hou) - Add debugfs 'ltssm_status' file for LGA- and HPA-based Cadence controllers (Hans Zhang) - Support up to x4 (not x2) lanes for J200 (Takuma Fujiwara) - Fix host/endpoint dependencies for cadence-plat driver to fix link error when cadence-plat is built-in but the host or endpoint driver is modular (Aksh Garg) Freescale i.MX6 PCIe controller driver: - Add imx6 intr/aer/pme interrupt lines for i.MX95 (Richard Zhu) - Remove PERST# checking from pci_host_common_parse_port() so callers can decide whether to fall back to legacy DT binding with PERST# in the host bridge (Sherry Sun) - Fix build issues when PCI_PWRCTRL_GENERIC or PCI_HOST_COMMON is a module (Arnd Bergmann) - Create pwrctrl devices only once by doing it from imx_pcie_probe() instead of imx_pcie_host_init(), which is used during both probe and resume (Sherry Sun) - Use 'dw_pcie_rp->skip_pwrctrl_off' to avoid powering off devices during suspend to preserve wakeup capability (Sherry Sun) - Add runtime PM support for i.MX95 to allow dynamic power management when the link is idle (Richard Zhu) Intel VMD host bridge driver: - Support device ID 0x28C1 and assume that BIOS has already enumerated the hierarchy below VMD and stored bus range info for OS to use (Nirmal Patel) - Add support for VMCONFIG BUS_RESTRICT_CFG=3, which makes it possible to enumerate downstream devices on Intel Arrow Lake-HX systems and probably others (Ali Alaei) - Pay attention to _OSC negotiation for VMD hierarchy only when running on bare metal, not when running in a VM (Nirmal Patel) - Add Nova Lake (NVL) and Dunlow (DNL) Device IDs (Szymon Durawa) MediaTek PCIe controller driver: - Add support for PCIe controller in EcoNet EN7528 and EN751221 SoCs (Caleb James DeLisle) MediaTek PCIe Gen3 controller driver: - Add mediatek-gen3 'memory-region' for restricted DMA buffer (Chen-Yu Tsai) NVIDIA Tegra264 PCIe controller driver: - Distinguish Tegra264 C0 PCIe controller for internal GPU from C1-C5 controllers so the unit address matches the first 'reg' entry (Thierry Reding) - Add Tegra264 Root Port stanzas to prepare for generic WAKE# handling (Thierry Reding) Qualcomm PCIe controller driver: - Add IPQ9650 compatible with global interrupt (Kathiravan Thirumoorthy) - Add IPQ5210 compatible with IPQ9574 fallback (Varadarajan Narayanan) - Add DT binding and driver support for Hawi SoC (Matthew Leung) - Skip PERST# GPIOs provided by downstream PCIe devices, which should be handled by drivers of those devices (Manivannan Sadhasivam) - Stop advertising Attention Button Present (no Qcom SoCs support Attention Buttons) so pciehp can use Presence Detect Changed events (Qiang Yu) Renesas R-Car PCIe controller driver: - Add rcar-gen4-pci-host optional 'msi-parent' for GIT ITS (Marek Vasut) - When MSI is enabled but iMSI-RX is not used, configure AXIINTC to allow GIT ITS to handle MSI (Marek Vasut) - Refactor GIC600 implementation to make it easier to add platforms that only support 32-bit addressing (Marek Vasut) - Add Renesas R-Car Gen4 S4/V4H/V4M to the list of GIC600 integrations that only support 32-bit addressing (Marek Vasut) Renesas RZ/G3S PCIe controller driver: - Add DT binding and driver support for RZ/V2H(P) SoC, which contains two PCIe controllers, configured either as a single x4 link or two independent x2 link controllers (Lad Prabhakar) SpacemiT K1 PCIe controller driver: - Add missing MODULE_DEVICE_TABLE() to generate module alias info for OF-based module autoloading (Pengpeng Hou) StarFive PCIe controller driver: - Fix resource leaks on error paths in host_init() (Ali Tariq) - Fix runtime PM handling and teardown ordering to avoid register access while power or clocks are disabled (Ali Tariq) - Check for runtime PM resume failure to avoid register access while power or clocks are disabled (Ali Tariq) Synopsys DesignWare PCIe controller driver: - Add LECARC PMU IDs to the DWC RAS/DES VSEC list so it can take advantage of the existing debugfs support for silicon debug, error injection, and event counters (Brett Zhou) - Factor pcie_valid_speed() and pci_bus_speed2lnkctl2() out of bwctrl so they can be shared by the DWC core (Hans Zhang) - Flush MSI writes from endpoint before unmapping the iATU, as we already do for MSI-X writes (Niklas Cassel) - Unmap MSI iATU window before mapping MSI-X window, to avoid a subsequent MSI write using a disabled aperture and losing the interrupt (Niklas Cassel) - Change endpoint .pre_init() and .init() callbacks to return errors and handle them (Marek Vasut) UltraRISC PCIe controller driver: - Add 'core', 'dbi', and 'aux' clocks to DT binding and manage them in the driver (Jia Wang) - Use module_platform_driver() since this may be built as a module, though not removable because IRQs can't be safely disposed (Jia Wang) MicroSemi Switchtec management driver: - Add Microchip PCI1008 device ID and include it in NTB DMA alias quirk (Logan Gunthorpe) Miscellaneous: - Document how to write PCI Host Controller drivers (Manivannan Sadhasivam) - Fix typos in documentation (D'Orus Tsitera) - Use %pe format specifier to print error pointers so we get symbolic errname when available (Krzysztof Wilczyński)"* tag 'pci-v7.3-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci: (124 commits) PCI: vmd: Add Nova Lake (NVL) and Dunlow (DNL) Device IDs PCI: tegra264: Add Tegra264 support dt-bindings: PCI: tegra264: Switch to PCIe Root Port bindings dt-bindings: PCI: tegra264: Strictly distinguish C0 from C1-C5 PCI/AER: Support Advisory Non-Fatal Errors PCI: Fix 32-bit config write in Intel PCH Root Port MPC ACS quirk PCI: dwc: Handle return value from endpoint .pre_init callback PCI: dwc: Handle return value from endpoint .init callback PCI: dwc: Add PCI ID for LECARC PCIe PMU PCI/ASPM: Mask ASPM states based on Devicetree properties PCI/ASPM: Disable/restore ASPM on every function for multi-function devices Documentation: PCI: Document how to write PCI Host Controller drivers PCI/ASPM: Use pcie_capability_clear_and_set_word() for ASPM disable/restore PCI: Add support for PCIe WAKE# interrupt PCI: Allow D3 for native hotplug-capable Root Ports on non-x86 platforms dt-bindings: PCI: Correct white-space style PCI/ASPM: Avoid L0s for Realtek RTS525A PCI: ultrarisc: Use module_platform_driver() PCI: ultrarisc: Get and enable DP1000 PCIe controller clocks dt-bindings: PCI: ultrarisc: Add required DP1000 PCIe clocks ...
