2019-11-21Drivers: hv: vmbus: Introduce table of VMBus protocol versionsAndrea Parri
The technique used to get the next VMBus version seems increasisly clumsy as the number of VMBus versions increases. Performance is not a concern since this is only done once during system boot; it's just that we'll end up with more lines of code than is really needed. As an alternative, introduce a table with the version numbers listed in order (from the most recent to the oldest). vmbus_connect() loops through the versions listed in the table until it gets an accepted connection or gets to the end of the table (invalid version).

2019-11-21PCI/ASPM: Remove PCIEASPM_DEBUG Kconfig option and related codeHeiner Kallweit
Previously, CONFIG_PCIEASPM_DEBUG enabled "link_state" and "clk_ctl" sysfs files that controlled ASPM. We believe these files were rarely if ever used. We recently added sysfs ASPM controls that are always present, so the debug code is no longer needed. Removing this debug code has been discussed for quite some time, see e.g. [0]. Remove PCIEASPM_DEBUG and the related code.

2019-11-21PCI/ASPM: Add sysfs attributes for controlling ASPM link statesHeiner Kallweit
Add sysfs attributes to Endpoints and other Upstream Ports to control ASPM, Clock PM, and L1 PM Substates. The new attributes are: /sys/devices/pci*/.../link/clkpm /sys/devices/pci*/.../link/l0s_aspm /sys/devices/pci*/.../link/l1_aspm /sys/devices/pci*/.../link/l1_1_aspm /sys/devices/pci*/.../link/l1_2_aspm /sys/devices/pci*/.../link/l1_1_pcipm /sys/devices/pci*/.../link/l1_2_pcipm An attribute is only visible if both ends of the Link leading to the device support the state. Writing y/1/on to the file enables the state; n/0/off disables it. These attributes can be used to tune the power/performance tradeoff for individual devices.

2019-11-21net: dsa: ocelot: add hardware timestamping support for FelixYangbo Lu
This patch is to reuse ocelot functions as possible to enable PTP clock and to support hardware timestamping on Felix. On TX path, timestamping works on packet which requires timestamp. The injection header will be configured accordingly, and skb clone requires timestamp will be added into a list. The TX timestamp is final handled in threaded interrupt handler when PTP timestamp FIFO is ready. On RX path, timestamping is always working. The RX timestamp could be got from extraction header.

This adds a new quirk NVME_QUIRK_NO_TEMP_THRESH_CHANGE to avoid changing the value of the temperature threshold feature for specific devices that show undesirable behavior. Guenter reported: "On my Intel NVME drive (SSDPEKKW512G7), writing any minimum limit on the Composite temperature sensor results in a temperature warning, and that warning is sticky until I reset the controller. It doesn't seem to matter which temperature I write; writing -273000 has the same result." The Intel NVMe has the latest firmware version installed, so this isn't a problem that was ever fixed.

2019-11-22nvme: hwmon: provide temperature min and max values for each sensorAkinobu Mita
According to the NVMe specification, the over temperature threshold and under temperature threshold features shall be implemented for Composite Temperature if a non-zero WCTEMP field value is reported in the Identify Controller data structure. The features are also implemented for all implemented temperature sensors (i.e., all Temperature Sensor fields that report a non-zero value). This provides the over temperature threshold and under temperature threshold for each sensor as temperature min and max values of hwmon sysfs attributes. The WCTEMP is already provided as a temperature max value for Composite Temperature, but this change isn't incompatible. Because the default value of the over temperature threshold for Composite Temperature is the WCTEMP. Now the alarm attribute for Composite Temperature indicates one of the temperature is outside of a temperature threshold. Because there is only a single bit in Critical Warning field that indicates a temperature is outside of a threshold. Example output from the "sensors" command: nvme-pci-0100 Adapter: PCI adapter Composite: +33.9°C (low = -273.1°C, high = +69.8°C) (crit = +79.8°C) Sensor 1: +34.9°C (low = -273.1°C, high = +65261.8°C) Sensor 2: +31.9°C (low = -273.1°C, high = +65261.8°C) Sensor 5: +47.9°C (low = -273.1°C, high = +65261.8°C) This also adds helper macros for kelvin from/to milli Celsius conversion, and replaces the repeated code in hwmon.c.

2019-11-21dma-mapping: treat dev->bus_dma_mask as a DMA limitNicolas Saenz Julienne
Using a mask to represent bus DMA constraints has a set of limitations. The biggest one being it can only hold a power of two (minus one). The DMA mapping code is already aware of this and treats dev->bus_dma_mask as a limit. This quirk is already used by some architectures although still rare. With the introduction of the Raspberry Pi 4 we've found a new contender for the use of bus DMA limits, as its PCIe bus can only address the lower 3GB of memory (of a total of 4GB). This is impossible to represent with a mask. To make things worse the device-tree code rounds non power of two bus DMA limits to the next power of two, which is unacceptable in this case. In the light of this, rename dev->bus_dma_mask to dev->bus_dma_limit all over the tree and treat it as such. Note that dev->bus_dma_limit should contain the higher accessible DMA address.

2019-11-21drm/amdgpu: Correct Transmit Margin masksBjorn Helgaas
Previously we masked PCIe Link Control 2 register values with "7 << 9", which was apparently intended to be the Transmit Margin field, but instead was the high order bit of Transmit Margin, the Enter Modified Compliance bit, and the Compliance SOS bit. Correct the mask to "7 << 7", which is the Transmit Margin field.

2019-11-21PCI: Allow building PCIe things without PCIEPORTBUSBjorn Helgaas
Some things in drivers/pci/pcie (aspm.c and ptm.c) do not depend on the PCIe portdrv, so we should be able to build them even if PCIEPORTBUS is not selected. Remove the PCIEPORTBUS guard from building pcie/.

drivers/pci/pcie/Kconfig is only sourced by drivers/pci/Kconfig, and only when PCI is defined, so there's no need to depend on PCI again. Remove the unnecessary dependencies.

2019-11-21pinctrl: Add pinmux & GPIO controller driver for a new SoCRahul Tanwar
Intel Lightning Mountain SoC has a pinmux controller & GPIO controller IP which controls pin multiplexing & configuration including GPIO functions selection & GPIO attributes configuration. This IP is not based on & does not have anything in common with Chassis specification. The pinctrl drivers under pinctrl/intel/* are all based upon Chassis spec compliant pinctrl IPs. So this driver doesn't fit & can not use pinctrl framework under pinctrl/intel/* and it requires a separate new driver. Add a new GPIO & pin control framework based driver for this IP.
