git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci Pull PCI updates from Bjorn Helgaas: "Enumeration: - Make pci_stop_dev() and pci_destroy_dev() safe so concurrent callers can't stop a device multiple times, even as we migrate from the global pci_rescan_remove_lock to finer-grained locking (Keith Busch) - Improve pci_walk_bus() implementation by making it recursive and moving locking up to avoid need for a 'locked' parameter (Keith Busch) - Unexport pci_walk_bus_locked(), which is only used internally by the PCI core (Keith Busch) - Detect some Thunderbolt chips that are built-in and hence 'trustworthy' by a heuristic since the 'ExternalFacingPort' and 'usb4-host-interface' ACPI properties are not quite enough (Esther Shimanovich) Resource management: - Use PCI bus addresses (not CPU addresses) in 'ranges' properties when building dynamic DT nodes so systems where PCI and CPU addresses differ work correctly (Andrea della Porta) - Tidy resource sizing and assignment with helpers to reduce redundancy (Ilpo Järvinen) - Improve pdev_sort_resources() 'bogus alignment' warning to be more specific (Ilpo Järvinen) Driver binding: - Convert driver .remove_new() callbacks to .remove() again to finish the conversion from returning 'int' to being 'void' (Sergio Paracuellos) - Export pcim_request_all_regions(), a managed interface to request all BARs (Philipp Stanner) - Replace pcim_iomap_regions_request_all() with pcim_request_all_regions(), and pcim_iomap_table()[n] with pcim_iomap(n), in the following drivers: ahci, crypto qat, crypto octeontx2, intel_th, iwlwifi, ntb idt, serial rp2, ALSA korg1212 (Philipp Stanner) - Remove the now unused pcim_iomap_regions_request_all() (Philipp Stanner) - Export pcim_iounmap_region(), a managed interface to unmap and release a PCI BAR (Philipp Stanner) - Replace pcim_iomap_regions(mask) with pcim_iomap_region(n), and pcim_iounmap_regions(mask) with pcim_iounmap_region(n), in the following drivers: fpga dfl-pci, block mtip32xx, gpio-merrifield, cavium (Philipp Stanner) Error handling: - Add sysfs 'reset_subordinate' to reset the entire hierarchy below a bridge; previously Secondary Bus Reset could only be used when there was a single device below a bridge (Keith Busch) - Warn if we reset a running device where the driver didn't register pci_error_handlers notification callbacks (Keith Busch) ASPM: - Disable ASPM L1 before touching L1 PM Substates to follow the spec closer and avoid a CPU load timeout on some platforms (Ajay Agarwal) - Set devices below Intel VMD to D0 before enabling ASPM L1 Substates as required per spec for all L1 Substates changes (Jian-Hong Pan) Power management: - Enable starfive controller runtime PM before probing host bridge (Mayank Rana) - Enable runtime power management for host bridges (Krishna chaitanya chundru) Power control: - Use of_platform_device_create() instead of of_platform_populate() to create pwrctl platform devices so we can control it based on the child nodes (Manivannan Sadhasivam) - Create pwrctrl platform devices only if there's a relevant power supply property (Manivannan Sadhasivam) - Add device link from the pwrctl supplier to the PCI dev to ensure pwrctl drivers are probed before the PCI dev driver; this avoids a race where pwrctl could change device power state while the PCI driver was active (Manivannan Sadhasivam) - Find pwrctl device for removal with of_find_device_by_node() instead of searching all children of the parent (Manivannan Sadhasivam) - Rename 'pwrctl' to 'pwrctrl' to match new bandwidth controller ('bwctrl') and hotplug files (Bjorn Helgaas) Bandwidth control: - Add read/modify/write locking for Link Control 2, which is used to manage Link speed (Ilpo Järvinen) - Extract Link Bandwidth Management Status check into pcie_lbms_seen(), where it can be shared between the bandwidth controller and quirks that use it to help retrain failed links (Ilpo Järvinen) - Re-add Link Bandwidth notification support with updates to address the reasons it was previously reverted (Alexandru Gagniuc, Ilpo Järvinen) - Add pcie_set_target_speed() and related functionality so drivers can manage PCIe Link speed based on thermal or other constraints (Ilpo Järvinen) - Add a thermal cooling driver to throttle PCIe Links via the existing thermal management framework (Ilpo Järvinen) - Add a userspace selftest for the PCIe bandwidth controller (Ilpo Järvinen) PCI device hotplug: - Add hotplug controller driver for Marvell OCTEON multi-function device where function 0 has a management console interface to enable/disable and provision various personalities for the other functions (Shijith Thotton) - Retain a reference to the pci_bus for the lifetime of a pci_slot to avoid a use-after-free when the thunderbolt driver resets USB4 host routers on boot, causing hotplug remove/add of downstream docks or other devices (Lukas Wunner) - Remove unused cpcihp struct cpci_hp_controller_ops.hardware_test (Guilherme Giacomo Simoes) - Remove unused cpqphp struct ctrl_dbg.ctrl (Christophe JAILLET) - Use pci_bus_read_dev_vendor_id() instead of hand-coded presence detection in cpqphp (Ilpo Järvinen) - Simplify cpqphp enumeration, which is already simple-minded and doesn't handle devices below hot-added bridges (Ilpo Järvinen) Virtualization: - Add ACS quirk for Wangxun FF5xxx NICs, which don't advertise an ACS capability but do isolate functions as though PCI_ACS_RR and PCI_ACS_CR were set, so the functions can be in independent IOMMU groups (Mengyuan Lou) TLP Processing Hints (TPH): - Add and document TLP Processing Hints (TPH) support so drivers can enable and disable TPH and the kernel can save/restore TPH configuration (Wei Huang) - Add TPH Steering Tag support so drivers can retrieve Steering Tag values associated with specific CPUs via an ACPI _DSM to improve performance by directing DMA writes closer to their consumers (Wei Huang) Data Object Exchange (DOE): - Wait up to 1 second for DOE Busy bit to clear before writing a request to the mailbox to avoid failures if the mailbox is still busy from a previous transfer (Gregory Price) Endpoint framework: - Skip attempts to allocate from endpoint controller memory window if the requested size is larger than the window (Damien Le Moal) - Add and document pci_epc_mem_map() and pci_epc_mem_unmap() to handle controller-specific size and alignment constraints, and add test cases to the endpoint test driver (Damien Le Moal) - Implement dwc pci_epc_ops.align_addr() so pci_epc_mem_map() can observe DWC-specific alignment requirements (Damien Le Moal) - Synchronously cancel command handler work in endpoint test before cleaning up DMA and BARs (Damien Le Moal) - Respect endpoint page size in dw_pcie_ep_align_addr() (Niklas Cassel) - Use dw_pcie_ep_align_addr() in dw_pcie_ep_raise_msi_irq() and dw_pcie_ep_raise_msix_irq() instead of open coding the equivalent (Niklas Cassel) - Avoid NULL dereference if Modem Host Interface Endpoint lacks 'mmio' DT property (Zhongqiu Han) - Release PCI domain ID of Endpoint controller parent (not controller itself) and before unregistering the controller, to avoid use-after-free (Zijun Hu) -

Add DT and driver support for using either of the two PolarFire Root Ports (Conor Dooley) NVIDIA Tegra194 PCIe controller driver: - Move endpoint controller cleanups that depend on refclk from the host to the notifier that tells us the host has deasserted PERST#, when refclk should be valid (Manivannan Sadhasivam) Qualcomm PCIe controller driver: - Add qcom SAR2130P DT binding with an additional clock (Dmitry Baryshkov) - Enable MSI interrupts if 'global' IRQ is supported, since a previous commit unintentionally masked them (Manivannan Sadhasivam) -

Move the OPP "operating-points-v2" table from the qcom,pcie-sm8450.yaml DT binding to qcom,pcie-common.yaml, where it can be used by other Qcom platforms (Qiang Yu) - Add 'global' SPI interrupt for events like link-up, link-down to qcom,pcie-x1e80100 DT binding so we can start enumeration when the link comes up (Qiang Yu) - Disable ASPM L0s for qcom,pcie-x1e80100 since the PHY is not tuned to support this (Qiang Yu) - Add ops_1_21_0 for SC8280X family SoC, which doesn't use the 'iommu-map' DT property and doesn't need BDF-to-SID translation (Qiang Yu) Rockchip PCIe controller driver: - Define ROCKCHIP_PCIE_AT_SIZE_ALIGN to replace magic 256 endpoint .align value (Damien Le Moal) - When unmapping an endpoint window, compute the region index instead of searching for it, and verify that the address was mapped (Damien Le Moal) - When mapping an endpoint window, verify that the address hasn't been mapped already (Damien Le Moal) - Implement pci_epc_ops.align_addr() for rockchip-ep (Damien Le Moal) - Fix MSI IRQ data mapping to observe the alignment constraint, which fixes intermittent page faults in memcpy_toio() and memcpy_fromio() (Damien Le Moal) -

Clear outbound address on unmap so dw_pcie_find_index() won't match an ATU index that was already unmapped (Damien Le Moal) - Use of_property_present() instead of of_property_read_bool() when testing for presence of non-boolean DT properties (Rob Herring) - Advertise 1MB size if endpoint supports Resizable BARs, which was inadvertently lost in v6.11 (Niklas Cassel) TI J721E PCIe driver: - Add PCIe support for J722S SoC (Siddharth Vadapalli) - Delay PCIE_T_PVPERL_MS (100 ms), not just PCIE_T_PERST_CLK_US (100 us), before deasserting PERST# to ensure power and refclk are stable (Siddharth Vadapalli) TI Keystone PCIe controller driver: - Set the 'ti,keystone-pcie' mode so v3.65a devices work in Root Complex mode (Kishon Vijay Abraham I) - Try to avoid unrecoverable SError for attempts to issue config transactions when the link is down; this is racy but the best we can do (Kishon Vijay Abraham I) Miscellaneous: -

2024-11-26Merge tag 'rust-6.13' of https://github.com/Rust-for-Linux/linuxLinus Torvalds
Pull rust updates from Miguel Ojeda: "Toolchain and infrastructure: - Enable a series of lints, including safety-related ones, e.g. the compiler will now warn about missing safety comments, as well as unnecessary ones. How safety documentation is organized is a frequent source of review comments, thus having the compiler guide new developers on where they are expected (and where not) is very nice. - Start using '#[expect]': an interesting feature in Rust (stabilized in 1.81.0) that makes the compiler warn if an expected warning was _not_ emitted. This is useful to avoid forgetting cleaning up locally ignored diagnostics ('#[allow]'s). - Introduce '.clippy.toml' configuration file for Clippy, the Rust linter, which will allow us to tweak its behaviour. For instance, our first use cases are declaring a disallowed macro and, more importantly, enabling the checking of private items. - Lints-related fixes and cleanups related to the items above. - Migrate from 'receiver_trait' to 'arbitrary_self_types': to get the kernel into stable Rust, one of the major pieces of the puzzle is the support to write custom types that can be used as 'self', i.e. as receivers, since the kernel needs to write types such as 'Arc' that common userspace Rust would not. 'arbitrary_self_types' has been accepted to become stable, and this is one of the steps required to get there. - Remove usage of the 'new_uninit' unstable feature. - Use custom C FFI types. Includes a new 'ffi' crate to contain our custom mapping, instead of using the standard library 'core::ffi' one. The actual remapping will be introduced in a later cycle. - Map '__kernel_{size_t,ssize_t,ptrdiff_t}' to 'usize'/'isize' instead of 32/64-bit integers. - Fix 'size_t' in bindgen generated prototypes of C builtins. - Warn on bindgen < 0.69.5 and libclang >= 19.1 due to a double issue in the projects, which we managed to trigger with the upcoming tracepoint support. It includes a build test since some distributions backported the fix (e.g. Debian -- thanks!). All major distributions we list should be now OK except Ubuntu non-LTS. 'macros' crate: - Adapt the build system to be able run the doctests there too; and clean up and enable the corresponding doctests. 'kernel' crate: - Add 'alloc' module with generic kernel allocator support and remove the dependency on the Rust standard library 'alloc' and the extension traits we used to provide fallible methods with flags. Add the 'Allocator' trait and its implementations '{K,V,KV}malloc'. Add the 'Box' type (a heap allocation for a single value of type 'T' that is also generic over an allocator and considers the kernel's GFP flags) and its shorthand aliases '{K,V,KV}Box'. Add 'ArrayLayout' type. Add 'Vec' (a contiguous growable array type) and its shorthand aliases '{K,V,KV}Vec', including iterator support. For instance, now we may write code such as: let mut v = KVec::new(); v.push(1, GFP_KERNEL)?; assert_eq!(&v, &[1]); Treewide, move as well old users to these new types. - 'sync' module: add global lock support, including the 'GlobalLockBackend' trait; the 'Global{Lock,Guard,LockedBy}' types and the 'global_lock!' macro. Add the 'Lock::try_lock' method. - 'error' module: optimize 'Error' type to use 'NonZeroI32' and make conversion functions public. - 'page' module: add 'page_align' function. - Add 'transmute' module with the existing 'FromBytes' and 'AsBytes' traits. - 'block::mq::request' module: improve rendered documentation. - 'types' module: extend 'Opaque' type documentation and add simple examples for the 'Either' types. drm/panic: - Clean up a series of Clippy warnings. Documentation: - Add coding guidelines for lints and the '#[expect]' feature. - Add Ubuntu to the list of distributions in the Quick Start guide. MAINTAINERS: - Add Danilo Krummrich as maintainer of the new 'alloc' module.

2024-11-25PCI: rockchip-ep: Handle PERST# signal in EP modeDamien Le Moal
Currently, the Rockchip PCIe endpoint controller driver does not handle the PERST# signal, which prevents detecting when link training should actually be started or if the host resets the device. This however can be supported using the controller reset_gpios property set as an input GPIO for endpoint mode. Modify the Rockchip PCI endpoint controller driver to get the reset_gpio and its associated interrupt which is serviced using a threaded IRQ with the function rockchip_pcie_ep_perst_irq_thread() as handler. This handler function notifies a link down event corresponding to the RC side asserting the PERST# signal using pci_epc_linkdown() when the gpio is high. Once the gpio value goes down, corresponding to the RC de-asserting the PERST# signal, link training is started. The polarity of the gpio interrupt trigger is changed from high to low after the RC asserted PERST#, and conversely changed from low to high after the RC de-asserts PERST#. Also, given that the host mode controller and the endpoint mode controller use two different property names for the same PERST# signal (ep_gpios property and reset_gpios property respectively), for clarity, rename the ep_gpio field of struct rockchip_pcie to perst_gpio.
