2023-02-03hwmon: (it87) Set second Super-IO chip in configuration modeFrank Crawford
On various Gigabyte AM4 boards (AB350, AX370), the second Super-IO chip (IT8792E) needs to be in configuration mode before accessing the first due to a bug in IT8792E which otherwise results in LPC bus access errors. This needs to be done before accessing the first Super-IO chip since the second chip may have been accessed prior to loading this driver. The problem is also reported to affect IT8795E, which is used on X299 boards and has the same chip ID as IT8792E (0x8733). It also appears to affect systems with IT8790E, which is used on some Z97X-Gaming boards as well as Z87X-OC, and other more recent Gigabyte boards.

2023-02-03hwmon: (coretemp) Simplify platform device handlingRobin Murphy
Coretemp's platform driver is unconventional. All the real work is done globally by the initcall and CPU hotplug notifiers, while the "driver" effectively just wraps an allocation and the registration of the hwmon interface in a long-winded round-trip through the driver core. The whole logic of dynamically creating and destroying platform devices to bring the interfaces up and down is error prone, since it assumes platform_device_add() will synchronously bind the driver and set drvdata before it returns, thus results in a NULL dereference if drivers_autoprobe is turned off for the platform bus. Furthermore, the unusual approach of doing that from within a CPU hotplug notifier, already commented in the code that it deadlocks suspend, also causes lockdep issues for other drivers or subsystems which may want to legitimately register a CPU hotplug notifier from a platform bus notifier. All of these issues can be solved by ripping this unusual behaviour out completely, simply tying the platform devices to the lifetime of the module itself, and directly managing the hwmon interfaces from the hotplug notifiers. There is a slight user-visible change in that /sys/bus/platform/drivers/coretemp will no longer appear, and /sys/devices/platform/coretemp.n will remain present if package n is hotplugged off, but hwmon users should really only be looking for the presence of the hwmon interfaces, whose behaviour remains unchanged.

For certain low latency applications, the RDMSR interruption exceeds the applications requirements. So do not create core files in sysfs, for CPUs which have isolation and nohz_full enabled.

2023-02-03hwmon: (peci/cputemp) Fix off-by-one in coretemp_label allocationZev Weiss
The find_last_bit() call produces the index of the highest-numbered core in core_mask; because cores are numbered from zero, the number of elements we need to allocate is one more than that.

Commit 4ef2774511dc ("hwmon: (nct6775) Convert register access to regmap API") fumbled the shifting & masking of the fan_div values such that odd-numbered fan divisors would always be set to zero.

2023-01-03hwmon: (ftsteutates) Fix scaling of measurementsArmin Wolf
A user complained that the ftsteutates driver was displaying bogus values since its introduction. This happens because the sensor measurements need to be scaled in order to produce meaningful results: - the fan speed needs to be multiplied by 60 since its in RPS - the temperature is in degrees celsius and needs an offset of 64 - the voltage is in 1/256 of 3.3V The offical datasheet says the voltage needs to be divided by 256, but this is likely an off-by-one-error, since even the BIOS devides by 255 (otherwise 3.3V could not be measured). The voltage channels additionally need a board-specific multiplier, however this can be done by the driver since its board-specific. The reason the missing scaling of measurements is the way Fujitsu used this driver when it was still out-of-tree. Back then, all scaling was done in userspace by libsensors, even the generic one. Tested on a Fujitsu DS3401-B1.
