This driver exposes hardware sensors of the Gigabyte AORUS Waterforce all-in-one CPU liquid coolers, which communicate through a proprietary USB HID protocol. Report offsets were initially discovered in [1] and confirmed by me on a Waterforce X240 by observing the sent reports from the official software. Available sensors are pump and fan speed in RPM, as well as coolant temperature. Also available through debugfs is the firmware version. Attaching a fan is optional and allows it to be controlled from the device. If it's not connected, the fan-related sensors will report zeroes. The addressable RGB LEDs and LCD screen are not supported in this driver and should be controlled through userspace tools. [1]: https://github.com/liquidctl/liquidctl/issues/167 Signed-off-by:

The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant. Signed-off-by:

Added custom channel-specific (temp1) attribute for resolution. The wait time for a conversion in one-shot mode (enable = 0) depends on the resolution. When resolution is 12-bit, the conversion time is 140ms, but the minimum update_interval is 125ms. Handled this problem by waiting an additional 15ms (125ms + 15ms = 140ms). Added 'mask' parameter to the shutdown_write() function. Now it can either write or update bits, depending on the value of mask. This is needed, because for alarms a write is necessary, but for resolution only the resolution bits should be updated. Signed-off-by:

Currently, i8k_dmi_table contains both entries used for DMI matching and entries used to override config options. This does not allow for differentiating between "its safe to issue raw SMM calls on this machine" and "its not safe to issue raw SMM calls on this machine, but here are some config values". Since future SMM backends will need to differentiate between those two cases, move those config entries into a separate table. i8k_dmi_table now serves as a general "its safe to issue raw SMM calls" table.

The EliteDesk 800 G6 stores a raw WMI string within the ACPI object in its BIOS corresponding to one instance of HPBIOS_PlatformEvents.Name. This is evidently a valid way of representing a WMI data item as far as the Microsoft ACPI-WMI mapper is concerned, but is preventing the driver from loading. This seems quite rare, but add support for such strings. Treating this as a quirk pretty much means adding that support anyway. Also clean up an oversight in update_numeric_sensor_from_wobj() in which the result of hp_wmi_strdup() was being used without error checking. Reported-by:

The PECI CPU sensors are available as soon as the CPU is powered, however the PECI DIMM sensors are available after DRAM has been trained and thresholds have been written by host firmware.

Bump the default timeout to 10 minutes in case the system starts without cached DDR5 training data. Signed-off-by:

Preliminary step to add the missing humidity attributes in the ABI documentation. Adding new elements alphabetically is a common practice that has been loosely followed in the sysfs-class-hwmon documentation.
