Add support for fan drawer's capability and present registers in order to set mapping between the fan drawers and tachometers. Some systems are equipped with fan drawers with one tachometer inside. Others with fan drawers with several tachometers inside. Using present register along with tachometer-to-drawer mapping allows to skip reading missed tachometers and expose input for them as zero, instead of exposing fault code returned by hardware.

2021-04-20hwmon: add driver for NZXT Kraken X42/X52/X62/X72Jonas Malaco
These are "all-in-one" CPU liquid coolers that can be monitored and controlled through a proprietary USB HID protocol. While the models have differently sized radiators and come with varying numbers of fans, they are all indistinguishable at the software level. The driver exposes fan/pump speeds and coolant temperature through the standard hwmon sysfs interface. Fan and pump control, while supported by the devices, are not currently exposed. The firmware accepts up to 61 trip points per channel (fan/pump), but the same set of trip temperatures has to be maintained for both; with pwmX_auto_point_Y_temp attributes, users would need to maintain this invariant themselves. Instead, fan and pump control, as well as LED control (which the device also supports for 9 addressable RGB LEDs on the CPU water block) are left for existing and already mature user-space tools, which can still be used alongside the driver, thanks to hidraw. A link to one, which I also maintain, is provided in the documentation. The implementation is based on USB traffic analysis. It has been runtime tested on x86_64, both as a built-in driver and as a module.

2021-04-20s390/pci: expose a PCI device's UID as its indexNiklas Schnelle
On s390 each PCI device has a user-defined ID (UID) exposed under /sys/bus/pci/devices/<dev>/uid. This ID was designed to serve as the PCI device's primary index and to match the device within Linux to the device configured in the hypervisor. To serve as a primary identifier the UID must be unique within the Linux instance, this is guaranteed by the platform if and only if the UID Uniqueness Checking flag is set within the CLP List PCI Functions response. In this sense the UID serves an analogous function as the SMBIOS instance number or ACPI index exposed as the "index" respectively "acpi_index" device attributes and used by e.g. systemd to set interface names. As s390 does not use and will likely never use ACPI nor SMBIOS there is no conflict and we can just expose the UID under the "index" attribute whenever UID Uniqueness Checking is active and get systemd's interface naming support for free.

When KEXEC is disabled, the UV build fails: arch/x86/platform/uv/uv_nmi.c:875:14: error: ‘uv_nmi_kexec_failed’ undeclared (first use in this function) Since uv_nmi_kexec_failed is only defined in the KEXEC_CORE #ifdef branch, this code cannot ever have been build tested: if (main) pr_err("UV: NMI kdump: KEXEC not supported in this kernel\n"); atomic_set(&uv_nmi_kexec_failed, 1); Nor is this use possible in uv_handle_nmi(): atomic_set(&uv_nmi_kexec_failed, 0); These bugs were introduced in this commit: d0a9964e9873: ("x86/platform/uv: Implement simple dump failover if kdump fails") Which added the uv_nmi_kexec_failed assignments to !KEXEC code, while making the definition KEXEC-only - apparently without testing the !KEXEC case. Instead of complicating the #ifdef maze, simplify the code by requiring X86_UV to depend on KEXEC_CORE. This pattern is present in other architectures as well. ( We'll remove the untested, 7 years old !KEXEC complications from the file in a separate commit. ) Fixes: d0a9964e9873: ("x86/platform/uv: Implement simple dump failover if kdump fails") Signed-off-by: Ingo Molnar <mingo@kernel.org> Cc: Mike Travis <travis@sgi.com> Cc: linux-kernel@vger.kernel.org
2021-04-19net/mlx5: DR, Add support for isolate_vl_tc QPYevgeny Kliteynik
When using SW steering, rule insertion rate depends on the RDMA RC QP performance used for writing to the ICM. During stress this QP is competing on the HW resources with all the other QPs that are used to send data. To protect SW steering QP's performance in such cases, we set this QP to use isolated VL. The VL number is reserved by FW and is not exposed to the driver. Support for this QP on isolated VL exists only when both force-loopback and isolate_vl_tc capabilities are set.

2021-04-19net/mlx5: DR, Add support for dynamic flex parserYevgeny Kliteynik
Flex parser is a HW parser that can support protocols that are not natively supported by the HCA, such as Geneve (TLV options) and GTP-U. There are 8 such parsers, and each of them can be assigned to parse a specific set of protocols. This patch adds misc4 match params which allows using a correct flex parser that was programmed to the required protocol.
