2022-07-27hwmon: (aquacomputer_d5next) Add support for Aquacomputer Quadro fan controllerAleksa Savic1-6/+11
Extend aquacomputer_d5next driver to expose hardware temperature sensors and fans of the Aquacomputer Quadro fan controller, which communicates through a proprietary USB HID protocol. Implemented by Jack Doan [1]. Four temperature sensors and PWM controllable fans are available. The liquid flow sensor is also exposed, implemented by Leonard Anderweit [2]. Additionally, serial number, firmware version and power-on count are exposed through debugfs. This driver has been tested on x86_64.

The TI USB8041 is a USB 3.0 hub controller with 4 ports. This initial version of the binding only describes USB related aspects of the USB8041, it does not cover the option of connecting the controller as an i2c slave.

Allow properties and usb-device child nodes as defined in usb-hcd.yaml, by using unevaluatedProperties: false. By the way, remove the "companion" property as it's redundant with usb-hcd.yaml. As example, this allows an onboard hub, to be described in generic-ehci controller node: usb { compatible = "generic-ehci"; #address-cells = <1>; #size-cells = <0>; /* onboard HUB */ hub@1 { compatible = "usb424,2514"; reg = <1>; vdd-supply = <&v3v3>; }; }; Without this, dtbs_check complains on '#address-cells', '#size-cells', 'hub@1' do not match any of the regexes: 'pinctrl-[0-9]+' From schema: ..../generic-ehci.yaml Reviewed-by: Rob Herring <robh@kernel.org> Signed-off-by: Fabrice Gasnier <fabrice.gasnier@foss.st.com> Link: https://lore.kernel.org/r/20220726080708.162547-2-fabrice.gasnier@foss.st.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2022-07-27dt-bindings: usb: typec: add bindings for stm32g0 controllerFabrice Gasnier1-0/+91
Add DT schema documentation for the STM32G0 Type-C PD (Power Delivery) controller. STM32G0 provides an integrated USB Type-C and power delivery interface. It can be programmed with a firmware to handle UCSI protocol over I2C interface. A GPIO is used as an interrupt line. It may be used as a wakeup source, so use optional "wakeup-source" and "power-domains" properties to support wakeup. The firmware itself may be flashed or later updated (optional). Choice is let to the application to allow firmware update. A default firmware could be already programmed in production and be customized (to not allow it). So the firmware-name is made optional to represent this option.

2022-07-27powerpc/pseries/mobility: set NMI watchdog factor during an LPMLaurent Dufour1-0/+12
During an LPM, while the memory transfer is in progress on the arrival side, some latencies are generated when accessing not yet transferred pages on the arrival side. Thus, the NMI watchdog may be triggered too frequently, which increases the risk to hit an NMI interrupt in a bad place in the kernel, leading to a kernel panic. Disabling the Hard Lockup Watchdog until the memory transfer could be a too strong work around, some users would want this timeout to be eventually triggered if the system is hanging even during an LPM. Introduce a new sysctl variable nmi_watchdog_factor. It allows to apply a factor to the NMI watchdog timeout during an LPM. Just before the CPUs are stopped for the switchover sequence, the NMI watchdog timer is set to watchdog_thresh + factor% A value of 0 has no effect. The default value is 200, meaning that the NMI watchdog is set to 30s during LPM (based on a 10s watchdog_thresh value). Once the memory transfer is achieved, the factor is reset to 0. Setting this value to a high number is like disabling the NMI watchdog during an LPM.

2022-07-25vfio: Replace phys_pfn with pages for vfio_pin_pages()Nicolin Chen1-1/+1
Most of the callers of vfio_pin_pages() want "struct page *" and the low-level mm code to pin pages returns a list of "struct page *" too. So there's no gain in converting "struct page *" to PFN in between. Replace the output parameter "phys_pfn" list with a "pages" list, to simplify callers. This also allows us to replace the vfio_iommu_type1 implementation with a more efficient one. And drop the pfn_valid check in the gvt code, as there is no need to do such a check at a page-backed struct page pointer. For now, also update vfio_iommu_type1 to fit this new parameter too.

2022-07-25vfio: Pass in starting IOVA to vfio_pin/unpin_pages APINicolin Chen1-2/+2
The vfio_pin/unpin_pages() so far accepted arrays of PFNs of user IOVA. Among all three callers, there was only one caller possibly passing in a non-contiguous PFN list, which is now ensured to have contiguous PFN inputs too. Pass in the starting address with "iova" alone to simplify things, so callers no longer need to maintain a PFN list or to pin/unpin one page at a time. This also allows VFIO to use more efficient implementations of pin/unpin_pages. For now, also update vfio_iommu_type1 to fit this new parameter too, while keeping its input intact (being user_iova) since we don't want to spend too much effort swapping its parameters and local variables at that level.

2022-07-25cxl/hdm: Commit decoder state to hardwareDan Williams1-0/+16
After all the soft validation of the region has completed, convey the region configuration to hardware while being careful to commit decoders in specification mandated order. In addition to programming the endpoint decoder base-address, interleave ways and granularity, the switch decoder target lists are also established. While the kernel can enforce spec-mandated commit order, it can not enforce spec-mandated reset order. For example, the kernel can't stop someone from removing an endpoint device that is occupying decoderN in a switch decoder where decoderN+1 is also committed. To reset decoderN, decoderN+1 must be torn down first. That "tear down the world" implementation is saved for a follow-on patch. Callback operations are provided for the 'commit' and 'reset' operations. While those callbacks may prove useful for CXL accelerators (Type-2 devices with memory) the primary motivation is to enable a simple way for cxl_test to intercept those operations.

2022-07-25cxl/region: Enable the assignment of endpoint decoders to regionsDan Williams1-0/+19
The region provisioning process involves allocating DPA to a set of endpoint decoders, and HPA plus the region geometry to a region device. Then the decoder is assigned to the region. At this point several validation steps can be performed to validate that the decoder is suitable to participate in the region.

2022-07-25cxl/region: Allocate HPA capacity to regionsDan Williams1-0/+29
After a region's interleave parameters (ways and granularity) are set, add a way for regions to allocate HPA (host physical address space) from the free capacity in their parent root-decoder. The allocator for this capacity reuses the 'struct resource' based allocator used for CONFIG_DEVICE_PRIVATE. Once the tuple of "ways, granularity, [uuid], and size" is set the region configuration transitions to the CXL_CONFIG_INTERLEAVE_ACTIVE state which is a precursor to allowing endpoint decoders to be added to a region.
