This control on the gain of a measurement used for time of flight sensing is standard but the expected values for different enviroments may not be.

2021-03-18thunderbolt: Add support for maxhopid XDomain propertyMika Westerberg1-0/+7
USB4 inter-domain spec mandates that the compatible hosts expose a new property "maxhopid" that tells the connection manager on the other side what is the maximum supported input HopID over the connection. Since this is depend on the lane adapter the cable is connected it needs to be filled in dynamically. For this reason we take a copy of the global properties and fill then for each XDomain connection upon first connect, and then keep updating it if the generation changes as services are being added/removed. We also take advantage of this copy to fill in the hostname. We also expose this maxhopid as an attribute under each XDomain device. While there drop kernel-doc entry for property_lock which seems to be left there when the structure was originally introduced. Signed-off-by: Mika Westerberg <mika.westerberg@linux.intel.com>

2021-03-11iio: documentation: Document accelerometer label useHans de Goede1-0/+7
Some 2-in-1 laptops / convertibles with 360° (yoga-style) hinges, have 2 accelerometers, 1 in their base and 1 in their display. In many cases the kernel can detect the location of each accelerometer based on e.g. information from the ACPI tables. It is important for userspace to know the location of the 2 accelerometers. Rather then adding a new sysfs-attribute for this we can relay this information to userspace by using standardized label strings for this. This mirrors how this is done for proximity sensors. This commit documents 2 new standardized label strings for this purpose: "accel-base" "accel-display" Note the "base" and "display" suffixes were chosen to match the values used for the systemd/udev hwdb.d/60-sensor.hwdb file's ACCEL_LOCATION property.

2021-02-26drivers/base/memory: don't store phys_device in memory blocksDavid Hildenbrand1-2/+3
No need to store the value for each and every memory block, as we can easily query the value at runtime. Reshuffle the members to optimize the memory layout. Also, let's clarify what the interface once was used for and why it's legacy nowadays. "phys_device" was used on s390x in older versions of lsmem[2]/chmem[3], back when they were still part of s390x-tools. They were later replaced by the variants in linux-utils. For example, RHEL6 and RHEL7 contain lsmem/chmem from s390-utils. RHEL8 switched to versions from util-linux on s390x [4]. "phys_device" was added with sysfs support for memory hotplug in commit 3947be1969a9 ("[PATCH] memory hotplug: sysfs and add/remove functions") in 2005. It always returned 0. s390x started returning something != 0 on some setups (if sclp.rzm is set by HW) in 2010 via commit 57b552ba0b2f ("memory hotplug/s390: set phys_device"). For s390x, it allowed for identifying which memory block devices belong to the same storage increment (RZM). Only if all memory block devices comprising a single storage increment were offline, the memory could actually be removed in the hypervisor. Since commit e5d709bb5fb7 ("s390/memory hotplug: provide memory_block_size_bytes() function") in 2013 a memory block device spans at least one storage increment - which is why the interface isn't really helpful/used anymore (except by old lsmem/chmem tools). There were once RFC patches to make use of "phys_device" in ACPI context; however, the underlying problem could be solved using different interfaces [1].

CXL is Compute Express Link which released the 2.0 specification in November. The Linux relevant changes in CXL 2.0 are support for an OS to dynamically assign address space to memory devices, support for switches, persistent memory, and hotplug. A Type-3 Memory Device is a PCI enumerated device presenting the CXL Memory Device Class Code and implementing the CXL.mem protocol. CXL.mem allows device to advertise CPU and I/O coherent memory to the system, i.e. typical "System RAM" and "Persistent Memory" in Linux /proc/iomem terms. In addition to the CXL.mem fast path there is an administrative command hardware mailbox interface for maintenance and provisioning. It is this command interface that is the focus of the initial driver. With this driver a CXL device that is mapped by the BIOS can be administered by Linux.

2021-02-23Input: cros-ec-keyb - expose function row physical map to userspacePhilip Chen1-0/+6
The top-row keys in a keyboard usually have dual functionalities. E.g. A function key "F1" is also an action key "Browser back". Therefore, when an application receives an action key code from a top-row key press, the application needs to know how to correlate the action key code with the function key code and do the conversion whenever necessary. Since the userpace already knows the key scanlines (row/column) associated with a received key code. Essentially, the userspace only needs a mapping between the key row/column and the matching physical location in the top row. So, enhance the cros-ec-keyb driver to create such a mapping and expose it to userspace in the form of a function_row_physmap attribute. The attribute would be a space separated ordered list of row/column codes for the keys in the function row, in a left-to-right order. The attribute will only be present when the device has a custom design for the top-row keys.

2021-02-17cxl/mem: Register CXL memX devicesDan Williams1-0/+26
Create the /sys/bus/cxl hierarchy to enumerate: * Memory Devices (per-endpoint control devices) * Memory Address Space Devices (platform address ranges with interleaving, performance, and persistence attributes) * Memory Regions (active provisioned memory from an address space device that is in use as System RAM or delegated to libnvdimm as Persistent Memory regions). For now, only the per-endpoint control devices are registered on the 'cxl' bus. However, going forward it will provide a mechanism to coordinate cross-device interleave.
