Merge tag 'pci-v7.1-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pciPull pci updates from Bjorn Helgaas: "Enumeration: - Allow TLP Processing Hints to be enabled for RCiEPs (George Abraham P) - Enable AtomicOps only if we know the Root Port supports them (Gerd Bayer) - Don't enable AtomicOps for RCiEPs since none of them need Atomic Ops and we can't tell whether the Root Complex would support them (Gerd Bayer) - Leave Precision Time Measurement disabled until a driver enables it to avoid PCIe errors (Mika Westerberg) - Make pci_set_vga_state() fail if bridge doesn't support VGA routing, i.e., PCI_BRIDGE_CTL_VGA is not writable, and return errors to vga_get() callers including userspace via /dev/vga_arbiter (Simon Richter) - Validate max-link-speed from DT in j721e, brcmstb, mediatek-gen3, rzg3s drivers (where the actual controller constraints are known), and remove validation from the generic OF DT accessor (Hans Zhang) - Remove pc110pad driver (no longer useful after 486 CPU support removed) and no_pci_devices() (pc110pad was the last user) (Dmitry Torokhov, Heiner Kallweit) Resource management: - Prevent assigning space to unimplemented bridge windows; previously we mistakenly assumed prefetchable window existed and assigned space and put a BAR there (Ahmed Naseef) - Avoid shrinking bridge windows to fit in the initial Root Port window; fixes one problem with devices with large BARs connected via switches, e.g., Thunderbolt (Ilpo Järvinen) - Pass full extent of empty space, not just the aligned space, to resource_alignf callback so free space before the requested alignment can be used (Ilpo Järvinen) - Place small resources before larger ones for better utilization of address space (Ilpo Järvinen) - Fix alignment calculation for resource size larger than align, e.g., bridge windows larger than the 1MB required alignment (Ilpo Järvinen) Reset: - Update slot handling so all ARI functions are treated as being in the same slot. They're all reset by Secondary Bus Reset, but previously drivers of ARI functions that appeared to be on a non-zero device weren't notified and fatal hardware errors could result (Keith Busch) - Make sysfs reset_subordinate hotplug safe to avoid spurious hotplug events (Keith Busch) - Hide Secondary Bus Reset ('bus') from sysfs reset_methods if masked by CXL because it has no effect (Vidya Sagar) - Avoid FLR for AMD NPU device, where it causes the device to hang (Lizhi Hou) Error handling: - Clear only error bits in PCIe Device Status to avoid accidentally clearing Emergency Power Reduction Detected (Shuai Xue) - Check for AER errors even in devices without drivers (Lukas Wunner) - Initialize ratelimit info so DPC and EDR paths log AER error information (Kuppuswamy Sathyanarayanan) Power control: - Add UPD720201/UPD720202 USB 3.0 xHCI Host Controller .compatible so generic pwrctrl driver can control it (Neil Armstrong) Hotplug: - Set LED_HW_PLUGGABLE for NPEM hotplug-capable ports so LED core doesn't complain when setting brightness fails because the endpoint is gone (Richard Cheng) Peer-to-peer DMA: - Allow wildcards in list of host bridges that support peer-to-peer DMA between hierarchy domains and add all Google SoCs (Jacob Moroni) Endpoint framework: - Advertise dynamic inbound mapping support in pci-epf-test and update host pci_endpoint_test to skip doorbell testing if not advertised by endpoint (Koichiro Den) - Return 0, not remaining timeout, when MHI eDMA ops complete so mhi_ep_ring_add_element() doesn't interpret non-zero as failure (Daniel Hodges) - Remove vntb and ntb duplicate resource teardown that leads to oops when .allow_link() fails or .drop_link() is called (Koichiro Den) - Disable vntb delayed work before clearing BAR mappings and doorbells to avoid oops caused by doing the work after resources have been torn down (Koichiro Den) - Add a way to describe reserved subregions within BARs, e.g., platform-owned fixed register windows, and use it for the RK3588 BAR4 DMA ctrl window (Koichiro Den) - Add BAR_DISABLED for BARs that will never be available to an EPF driver, and change some BAR_RESERVED annotations to BAR_DISABLED (Niklas Cassel) - Add NTB .get_dma_dev() callback for cases where DMA API requires a different device, e.g., vNTB devices (Koichiro Den) - Add reserved region types for MSI-X Table and PBA so Endpoint controllers can them as describe hardware-owned regions in a BAR_RESERVED BAR (Manikanta Maddireddy) - Make Tegra194/234 BAR0 programmable and remove 1MB size limit (Manikanta Maddireddy) - Expose Tegra BAR2 (MSI-X) and BAR4 (DMA) as 64-bit BAR_RESERVED (Manikanta Maddireddy) - Add Tegra194 and Tegra234 device table entries to pci_endpoint_test (Manikanta Maddireddy) - Skip the BAR subrange selftest if there are not enough inbound window resources to run the test (Christian Bruel) New native PCIe controller drivers: - Add DT binding and driver for Andes QiLai SoC PCIe host controller (Randolph Lin) - Add DT binding and driver for ESWIN PCIe Root Complex (Senchuan Zhang) Baikal T-1 PCIe controller driver: - Remove driver since it never quite became usable (Andy Shevchenko) Cadence PCIe controller driver: - Implement byte/word config reads with dword (32-bit) reads because some Cadence controllers don't support sub-dword accesses (Aksh Garg) CIX Sky1 PCIe controller driver: - Add 'power-domains' to DT binding for SCMI power domain (Gary Yang) Freescale i.MX6 PCIe controller driver: - Add i.MX94 and i.MX943 to fsl,imx6q-pcie-ep DT binding (Richard Zhu) - Delay instead of polling for L2/L3 Ready after PME_Turn_off when suspending i.MX6SX because LTSSM registers are inaccessible (Richard Zhu) - Separate PERST# assertion (for resetting endpoints) from core reset (for resetting the RC itself) to prepare for new DTs with PERST# GPIO in per-Root Port nodes (Sherry Sun) - Retain Root Port MSI capability on i.MX7D, i.MX8MM, and i.MX8MQ so MSI from downstream devices will work (Richard Zhu) - Fix i.MX95 reference clock source selection when internal refclk is used (Franz Schnyder) Freescale Layerscape PCIe controller driver: - Allow building as a removable module (Sascha Hauer) MediaTek PCIe Gen3 controller driver: - Use dev_err_probe() to simplify error paths and make deferred probe messages visible in /sys/kernel/debug/devices_deferred (Chen-Yu Tsai) - Power off device if setup fails (Chen-Yu Tsai) - Integrate new pwrctrl API to enable power control for WiFi/BT adapters on mainboard or in PCIe or M.2 slots (Chen-Yu Tsai) NVIDIA Tegra194 PCIe controller driver: - Poll less aggressively and non-atomically for PME_TO_Ack during transition to L2 (Vidya Sagar) - Disable LTSSM after transition to Detect on surprise link down to stop toggling between Polling and Detect (Manikanta Maddireddy) - Don't force the device into the D0 state before L2 when suspending or shutting down the controller (Vidya Sagar) - Disable PERST# IRQ only in Endpoint mode because it's not registered in Root Port mode (Manikanta Maddireddy) - Handle 'nvidia,refclk-select' as optional (Vidya Sagar) - Disable direct speed change in Endpoint mode so link speed change is controlled by the host (Vidya Sagar) - Set LTR values before link up to avoid bogus LTR messages with 0 latency (Vidya Sagar) - Allow system suspend when the Endpoint link is down (Vidya Sagar) - Use DWC IP core version, not Tegra custom values, to avoid DWC core version check warnings (Manikanta Maddireddy) - Apply ECRC workaround to devices based on DesignWare 5.00a as well as 4.90a (Manikanta Maddireddy) - Disable PM Substate L1.2 in Endpoint mode to work around Tegra234 erratum (Vidya Sagar) - Delay post-PERST# cleanup until core is powered on to avoid CBB timeout (Manikanta Maddireddy) - Assert CLKREQ# so switches that forward it to their downstream side can bring up those links successfully (Vidya Sagar) - Calibrate pipe to UPHY for Endpoint mode to reset stale PLL state from any previous bad link state (Vidya Sagar) - Remove IRQF_ONESHOT flag from Endpoint interrupt registration so DMA driver and Endpoint controller driver can share the interrupt line (Vidya Sagar) - Enable DMA interrupt to support DMA in both Root Port and Endpoint modes (Vidya Sagar) - Enable hardware link retraining after link goes down in Endpoint mode (Vidya Sagar) - Add DT binding and driver support for core clock monitoring (Vidya Sagar) Qualcomm PCIe controller driver: - Advertise 'Hot-Plug Capable' and set 'No Command Completed Support' since Qcom Root Ports support hotplug events like DL_Up/Down and can accept writes to Slot Control without delays between writes (Krishna Chaitanya Chundru) Renesas R-Car PCIe controller driver: - Mark Endpoint BAR0 and BAR2 as Resizable (Koichiro Den) - Reduce EPC BAR alignment requirement to 4K (Koichiro Den) Renesas RZ/G3S PCIe controller driver: - Add RZ/G3E to DT binding and to driver (John Madieu) - Assert (not deassert) resets in probe error path (John Madieu) - Assert resets in suspend path in reverse order they were deasserted during probe (John Madieu) - Rework inbound window algorithm to prevent mapping more than intended region and enforce alignment on size, to prepare for RZ/G3E support (John Madieu) Rockchip DesignWare PCIe controller driver: - Add tracepoints for PCIe controller LTSSM transitions and link rate changes (Shawn Lin) - Trace LTSSM events collected by the dw-rockchip debug FIFO (Shawn Lin) SOPHGO PCIe controller driver: - Disable ASPM L0s and L1 on Sophgo 2042 PCIe Root Ports that advertise support for them (Yao Zi) Synopsys DesignWare PCIe controller driver: - Continue with system suspend even if an Endpoint doesn't respond with PME_TO_Ack message (Manivannan Sadhasivam) - Set Endpoint MSI-X Table Size in the correct function of a multi-function device when configuring MSI-X, not in Function 0 (Aksh Garg) - Set Max Link Width and Max Link Speed for all functions of a multi-function device, not just Function 0 (Aksh Garg) - Expose PCIe event counters in groups 5-7 in debugfs (Hans Zhang) Miscellaneous: - Warn only once about invalid ACS kernel parameter format (Richard Cheng) - Suppress FW_BUG warning when writing sysfs 'numa_node' with the current value (Li RongQing) - Drop redundant 'depends on PCI' from Kconfig (Julian Braha)"* tag 'pci-v7.1-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci: (165 commits) PCI/P2PDMA: Add Google SoCs to the P2P DMA host bridge list PCI/P2PDMA: Allow wildcard Device IDs in host bridge list PCI: sg2042: Avoid L0s and L1 on Sophgo 2042 PCIe Root Ports PCI: cadence: Add flags for disabling ASPM capability for broken Root Ports PCI: tegra194: Add core monitor clock support dt-bindings: PCI: tegra194: Add monitor clock support PCI: tegra194: Enable hardware hot reset mode in Endpoint mode PCI: tegra194: Enable DMA interrupt PCI: tegra194: Remove IRQF_ONESHOT flag during Endpoint interrupt registration PCI: tegra194: Calibrate pipe to UPHY for Endpoint mode PCI: tegra194: Assert CLKREQ# explicitly by default PCI: tegra194: Fix CBB timeout caused by DBI access before core power-on PCI: tegra194: Disable L1.2 capability of Tegra234 EP PCI: dwc: Apply ECRC workaround to DesignWare 5.00a as well PCI: tegra194: Use DWC IP core version PCI: tegra194: Free up Endpoint resources during remove() PCI: tegra194: Allow system suspend when the Endpoint link is not up PCI: tegra194: Set LTR message request before PCIe link up in Endpoint mode PCI: tegra194: Disable direct speed change for Endpoint mode PCI: tegra194: Use devm_gpiod_get_optional() to parse "nvidia,refclk-select" ...
