The following changes since commit ac9a78681b921877518763ba0e89202254349d1b: Linux 6.4-rc1 (2023-05-07 13:34:35 -0700) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci.git tags/pci-v6.5-changes for you to fetch changes up to 6ecac465eee887de7ceda7ffe3bccf538eb786bc: Merge branch 'pci/controller/remove-void-callbacks' (2023-06-26 13:00:00 -0500) ---------------------------------------------------------------- Enumeration: - Export pcie_retrain_link() for use outside ASPM - Add Data Link Layer Link Active Reporting as another way for pcie_retrain_link() to determine the link is up - Work around link training failures (especially on the ASMedia ASM2824 switch) by training first at 2.5GT/s and then attempting higher rates Resource management: - When we coalesce host bridge windows, remove invalidated resources from the resource tree so future allocations work correctly Hotplug: - Cancel bringup sequence if card is not present, to keep from blinking Power Indicator indefinitely - Reassign bridge resources if necessary for ACPI hotplug Driver binding: - Convert platform_device .remove() callbacks to return void instead of a mostly useless int Power management: - Reduce wait time for secondary bus to be ready to speed up resume - Avoid putting EloPOS E2/S2/H2 (as well as Elo i2) PCIe Ports in D3cold - Call _REG when transitioning D-states so AML that uses the PCI config space OpRegion works, which fixes some ASMedia GPIO controllers after resume Virtualization: - Delay extra 250ms after FLR of Solidigm P44 Pro NVMe to avoid KVM hang when guest is rebooted - Add function 1 DMA alias quirk for Marvell 88SE9235 Error handling: - Unexport pci_save_aer_state() since it's only used in drivers/pci/ - Drop recommendation for drivers to configure AER Capability, since the PCI core does this for all devices ASPM: - Disable ASPM on MFD function removal to avoid use-after-free - Tighten up pci_enable_link_state() and pci_disable_link_state() interfaces so they don't enable/disable states the driver didn't specify - Avoid link retraining race that can happen if ASPM sets link control parameters while the link is in the midst of training for some other reason Endpoint framework: - Change "PCI Endpoint Virtual NTB driver" Kconfig prompt to be different from "PCI Endpoint NTB driver" - Automatically create a function specific attributes group for endpoint drivers to avoid reference counting issues - Fix many EPC test issues - Return pci_epf_type_add_cfs() error if EPF has no driver - Add kernel-doc for pci_epc_raise_irq() and pci_epc_map_msi_irq() MSI vector parameters - Pass EPF device ID to driver probe functions - Return -EALREADY if EPC has already been started/stopped - Add linkdown notifier support and use it in qcom-ep - Add Bus Master Enable event support and use it in qcom-ep - Add Qualcomm Modem Host Interface (MHI) endpoint driver - Add Layerscape PME interrupt handling to manage link-up notification Cadence PCIe controller driver: - Wait for link retrain to complete when working around the J721E i2085 erratum with Gen2 mode Faraday FTPC100 PCI controller driver: - Release clock resources on error paths Freescale i.MX6 PCIe controller driver: - Save and restore Root Port MSI control to work around hardware defect Intel VMD host bridge driver: - Reset VMD config register between soft reboots - Capture pci_reset_bus() return value instead of printing junk when it fails Qualcomm PCIe controller driver: - Add SDX65 endpoint compatible string to DT binding - Disable register write access after init for IP v2.3.3, v2.9.0 - Use DWC helpers for enabling/disabling writes to DBI registers - Hide slot hotplug capability for IP v1.0.0, v1.9.0, v2.1.0, v2.3.2, v2.3.3, v2.7.0, v2.9.0 - Reuse v2.3.2 post-init sequence for v2.4.0 Renesas R-Car PCIe controller driver: - Remove unused static pcie_base and pcie_dev Rockchip PCIe controller driver: - Remove writes to unused registers - Write endpoint Device ID using correct register - Assert PCI Configuration Enable bit after probe so endpoint responds instead of generating Request Retry Status messages - Poll waiting for PHY PLLs to lock - Update RK3399 example DT binding to be valid - Use RK3399 PCIE_CLIENT_LEGACY_INT_CTRL to generate INTx instead of manually generating PCIe message - Use multiple windows to avoid address translation conflicts - Use u32 (not u16) when accessing 32-bit registers - Hide MSI-X Capability, since RK3399 can't generate MSI-X - Set endpoint controller required alignment to 256 Synopsys DesignWare PCIe controller driver: - Wait for link to come up only if we've initiated link training Miscellaneous: - Add pci_clear_master() stub for non-CONFIG_PCI ---------------------------------------------------------------- Ajay Agarwal (6): PCI/ASPM: Disable only ASPM_STATE_L1 when driver disables L1 PCI/ASPM: Set only ASPM_STATE_L1 when driver enables L1 PCI/ASPM: Set ASPM_STATE_L1 when driver enables L1.1 or L1.2 PCI/ASPM: Rename L1.2-specific functions from 'l1ss' to 'l12' PCI/ASPM: Remove unnecessary ASPM_STATE_L1SS check PCI: dwc: Wait for link up only if link is started Andy Shevchenko (1): PCI: of: Propagate firmware node by calling device_set_node() Ben Dooks (1): PCI: Add PCI_EXT_CAP_ID_PL_32GT define Bjorn Helgaas (26): PCI: pciehp: Simplify Attention Button logging PCI: Expand comment about sorting pci_ids.h entries PCI: Unexport pci_save_aer_state() Documentation: PCI: Drop recommendation to configure AER Capability Documentation: PCI: Update cross references to .rst files Documentation: PCI: Tidy AER documentation PCI/ASPM: Return 0 or -ETIMEDOUT from pcie_retrain_link() PCI/ACPI: Validate acpi_pci_set_power_state() parameter Merge branch 'pci/aer' Merge branch 'pci/aspm' Merge branch 'pci/enumeration' Merge branch 'pci/hotplug' Merge branch 'pci/pm' Merge branch 'pci/resource' Merge branch 'pci/virtualization' Merge branch 'pci/misc' Merge branch 'pci/controller/dt' Merge branch 'pci/controller/cadence' Merge branch 'pci/controller/dwc' Merge branch 'pci/pci/ftpci100' Merge branch 'pci/controller/qcom' Merge branch 'pci/controller/rcar' Merge branch 'pci/controller/rockchip' Merge branch 'pci/controller/vmd' Merge branch 'pci/controller/endpoint' Merge branch 'pci/controller/remove-void-callbacks' Damien Le Moal (19): PCI: rockchip: Set address alignment for endpoint mode PCI: endpoint: Automatically create a function specific attributes group PCI: endpoint: Move pci_epf_type_add_cfs() code PCI: epf-test: Fix DMA transfer completion initialization PCI: epf-test: Fix DMA transfer completion detection PCI: epf-test: Use dmaengine_submit() to initiate DMA transfer PCI: epf-test: Simplify read/write/copy test functions PCI: epf-test: Simplify pci_epf_test_raise_irq() PCI: epf-test: Simplify IRQ test commands execution PCI: epf-test: Improve handling of command and status registers PCI: epf-test: Cleanup pci_epf_test_cmd_handler() PCI: epf-test: Cleanup request result handling PCI: epf-test: Simplify DMA support checks PCI: epf-test: Simplify transfers result print misc: pci_endpoint_test: Free IRQs before removing the device misc: pci_endpoint_test: Re-init completion for every test misc: pci_endpoint_test: Do not write status in IRQ handler misc: pci_endpoint_test: Simplify pci_endpoint_test_msi_irq() PCI: endpoint: Improve pci_epf_type_add_cfs() Ding Hui (1): PCI/ASPM: Disable ASPM on MFD function removal to avoid use-after-free Frank Li (2): PCI: endpoint: pci-epf-vntb: Fix typo in comments PCI: layerscape: Add the endpoint linkup notifier support Geert Uytterhoeven (1): PCI: rcar-host: Remove unused static pcie_base and pcie_dev Igor Mammedov (1): PCI: acpiphp: Reassign resources on bridge if necessary Ilpo Järvinen (2): PCI/ASPM: Factor out pcie_wait_for_retrain() PCI/ASPM: Avoid link retraining race Junyan Ye (1): PCI: ftpci100: Release the clock resources Maciej W.
