The following changes since commit 3123109284176b1532874591f7c81f3837bbdc17: Linux 5.18-rc1 (2022-04-03 14:08:21 -0700) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci.git tags/pci-v5.19-changes for you to fetch changes up to 32f479d05a445b52cb7fcbe6e06f579fb852be71: Merge branch 'remotes/lorenzo/pci/vmd' (2022-05-24 16:42:28 -0500) ---------------------------------------------------------------- Resource management: - Restrict E820 clipping to PCI host bridge windows (Bjorn Helgaas) - Log E820 clipping better (Bjorn Helgaas) - Add kernel cmdline options to enable/disable E820 clipping (Hans de Goede) - Disable E820 reserved region clipping for IdeaPads, Yoga, Yoga Slip, Acer Spin 5, Clevo Barebone systems where clipping leaves no usable address space for touchpads, Thunderbolt devices, etc (Hans de Goede) - Disable E820 clipping by default starting in 2023 (Hans de Goede) PCI device hotplug: - Include files to remove implicit dependencies (Christophe Leroy) - Only put Root Ports in D3 if they can signal and wake from D3 so AMD Yellow Carp doesn't miss hotplug events (Mario Limonciello) Power management: - Define pci_restore_standard_config() only for CONFIG_PM_SLEEP since it's unused otherwise (Krzysztof Kozlowski) - Power up devices completely, including anything platform firmware needs to do, during runtime resume (Rafael J. Wysocki) - Move pci_resume_bus() to PM callbacks so we observe the required bridge power-up delays (Rafael J. Wysocki) - Drop unneeded runtime_d3cold device flag (Rafael J. Wysocki) - Split pci_raw_set_power_state() between pci_power_up() and a new pci_set_low_power_state() (Rafael J. Wysocki) - Set current_state to D3cold if config read returns ~0, indicating the device is not accessible (Rafael J. Wysocki) - Do not call pci_update_current_state() from pci_power_up() so BARs and ASPM config are restored correctly (Rafael J. Wysocki) - Write 0 to PMCSR in pci_power_up() in all cases (Rafael J. Wysocki) - Split pci_power_up() to pci_set_full_power_state() to avoid some redundant operations (Rafael J. Wysocki) - Skip restoring BARs if device is not in D0 (Rafael J. Wysocki) - Rearrange and clarify pci_set_power_state() (Rafael J. Wysocki) - Remove redundant BAR restores from pci_pm_thaw_noirq() (Rafael J. Wysocki) Virtualization: - Acquire device lock before config space access lock to avoid AB/BA deadlock with sriov_numvfs_store() (Yicong Yang) Error handling: - Clear MULTI_ERR_COR/UNCOR_RCV bits, which a race could previously leave permanently set (Kuppuswamy Sathyanarayanan) Peer-to-peer DMA: - Whitelist Intel Skylake-E Root Ports regardless of which devfn they are (Shlomo Pongratz) ASPM: - Override L1 acceptable latency advertised by Intel DG2 so ASPM L1 can be enabled (Mika Westerberg) Cadence PCIe controller driver: - Set up device-specific register to allow PTM Responder to be enabled by the normal architected bit (Christian Gmeiner) - Override advertised FLR support since the controller doesn't implement FLR correctly (Parshuram Thombare) Cadence PCIe endpoint driver: - Correct bitmap size for the ob_region_map of outbound window usage (Dan Carpenter) Freescale i.MX6 PCIe controller driver: - Fix PERST# assertion/deassertion so we observe the required delays before accessing device (Francesco Dolcini) Freescale Layerscape PCIe controller driver: - Add "big-endian" DT property (Hou Zhiqiang) - Update SCFG DT property (Hou Zhiqiang) - Add "aer", "pme", "intr" DT properties (Li Yang) - Add DT compatible strings for ls1028a (Xiaowei Bao) Intel VMD host bridge driver: - Assign VMD IRQ domain before enumeration to avoid IOMMU interrupt remapping errors when MSI-X remapping is disabled (Nirmal Patel) - Revert VMD workaround that kept MSI-X remapping enabled when IOMMU remapping was enabled (Nirmal Patel) Marvell MVEBU PCIe controller driver: - Add of_pci_get_slot_power_limit() to parse the 'slot-power-limit-milliwatt' DT property (Pali Rohár) - Add mvebu support for sending Set_Slot_Power_Limit message (Pali Rohár) MediaTek PCIe controller driver: - Fix refcount leak in mtk_pcie_subsys_powerup() (Miaoqian Lin) MediaTek PCIe Gen3 controller driver: - Reset PHY and MAC at probe time (AngeloGioacchino Del Regno) Microchip PolarFlare PCIe controller driver: - Add chained_irq_enter()/chained_irq_exit() calls to mc_handle_msi() and mc_handle_intx() to avoid lost interrupts (Conor Dooley) - Fix interrupt handling race (Daire McNamara) NVIDIA Tegra194 PCIe controller driver: - Drop tegra194 MSI register save/restore, which is unnecessary since the DWC core does it (Jisheng Zhang) Qualcomm PCIe controller driver: - Add SM8150 SoC DT binding and support (Bhupesh Sharma) - Fix pipe clock imbalance (Johan Hovold) - Fix runtime PM imbalance on probe errors (Johan Hovold) - Fix PHY init imbalance on probe errors (Johan Hovold) - Convert DT binding to YAML (Dmitry Baryshkov) - Update DT binding to show that resets aren't required for MSM8996/APQ8096 platforms (Dmitry Baryshkov) - Add explicit register names per chipset in DT binding (Dmitry Baryshkov) - Add sc7280-specific clock and reset definitions to DT binding (Dmitry Baryshkov) Rockchip PCIe controller driver: - Fix bitmap size when searching for free outbound region (Dan Carpenter) Rockchip DesignWare PCIe controller driver: - Remove "snps,dw-pcie" from rockchip-dwc DT "compatible" property because it's not fully compatible with rockchip (Peter Geis) - Reset rockchip-dwc controller at probe (Peter Geis) - Add rockchip-dwc INTx support (Peter Geis) Synopsys DesignWare PCIe controller driver: - Return error instead of success if DMA mapping of MSI area fails (Jiantao Zhang) Miscellaneous: - Change pci_set_dma_mask() documentation references to dma_set_mask() (Alex Williamson) ---------------------------------------------------------------- Alex Williamson (1): PCI/doc: Update obsolete pci_set_dma_mask() references AngeloGioacchino Del Regno (1): PCI: mediatek-gen3: Assert resets to ensure expected init state Bhupesh Sharma (2): dt-bindings: pci: qcom: Document PCIe bindings for SM8150 SoC PCI: qcom: Add SM8150 SoC support Bjorn Helgaas (22): x86/PCI: Eliminate remove_e820_regions() common subexpressions x86: Log resource clipping for E820 regions x86/PCI: Clip only host bridge windows for E820 regions Merge branch 'pci/aspm' Merge branch 'pci/error' Merge branch 'pci/hotplug' Merge branch 'pci/misc' Merge branch 'pci/p2pdma' Merge branch 'pci/pm' Merge branch 'pci/resource' Merge branch 'pci/virtualization' Merge branch 'remotes/lorenzo/pci/cadence' Merge branch 'remotes/lorenzo/pci/dwc' Merge branch 'remotes/lorenzo/pci/imx6' Merge branch 'remotes/lorenzo/pci/layerscape' Merge branch 'remotes/lorenzo/pci/mediatek' Merge branch 'remotes/lorenzo/pci/microchip' Merge branch 'remotes/lorenzo/pci/power-slot' Merge branch 'pci/host/qcom' Merge branch 'remotes/lorenzo/pci/rockchip' Merge branch 'remotes/lorenzo/pci/versatile' Merge branch 'remotes/lorenzo/pci/vmd' Christian Gmeiner (1): PCI: cadence: Allow PTM Responder to be enabled Christophe Leroy (1): PCI: hotplug: Clean up include files Colin Ian King (1): PCI: versatile: Remove redundant variable retval Conor Dooley (1): PCI: microchip: Add missing chained_irq_enter()/exit() calls Daire McNamara (1): PCI: microchip: Fix potential race in interrupt handling Dan Carpenter (2): PCI: cadence: Fix find_first_zero_bit() limit PCI: rockchip: Fix find_first_zero_bit() limit Dmitry Baryshkov (5): PCI: qcom-ep: Move enable/disable resources code to common functions dt-bindings: PCI: qcom: Convert to YAML dt-bindings: PCI: qcom: Do not require resets on msm8996 platforms dt-bindings: PCI: qcom: Specify reg-names explicitly dt-bindings: PCI: qcom: Add schema for sc7280 chipset Francesco Dolcini (1): PCI: imx6: Fix PERST# start-up sequence Hans de Goede (3): x86/PCI: Add kernel cmdline options to use/ignore E820 reserved regions x86/PCI: Disable E820 reserved region clipping via quirks x86/PCI: Disable E820 reserved region clipping starting in 2023 Hou Zhiqiang (2): dt-bindings: pci: layerscape-pci: Add a optional property big-endian dt-bindings: pci: layerscape-pci: Update the description of SCFG property Jiantao Zhang (1): PCI: dwc: Fix setting error return on MSI DMA mapping failure Jisheng Zhang (1): PCI: tegra194: Remove unnecessary MSI enable reg save and restore Johan Hovold (3): PCI: qcom: Fix pipe clock imbalance PCI: qcom: Fix runtime PM imbalance on probe errors PCI: qcom: Fix unbalanced PHY init on probe errors Krzysztof Kozlowski (1): PCI/PM: Define pci_restore_standard_config() only for CONFIG_PM_SLEEP Kuppuswamy Sathyanarayanan (1): PCI/AER: Clear MULTI_ERR_COR/UNCOR_RCV bits Li Yang (1): dt-bindings: pci: layerscape-pci: define AER/PME interrupts Mario Limonciello (1): PCI/ACPI: Allow D3 only if Root Port can signal and wake from D3 Miaoqian Lin (1): PCI: mediatek: Fix refcount leak in mtk_pcie_subsys_powerup() Mika Westerberg (1): PCI/ASPM: Make Intel DG2 L1 acceptable latency unlimited Nirmal Patel (2): PCI: vmd: Assign VMD IRQ domain before enumeration PCI: vmd: Revert 2565e5b69c44 ("PCI: vmd: Do not disable MSI-X remapping if interrupt remapping is enabled by IOMMU.")
