This four part series updates the oxpsensors module to bring it in line
with its Windows OneXPlayer counterpart. First, it adds support for all
2024, 2025 OneXPlayer handhelds and their special variants.
Then, it adds the new charge limiting and bypass features that were first
introduced in the X1 and retrofit to older OneXFly variants and for
controlling the turbo led found in the X1 models. For Bypass, it adds a new
bypass variant BypassS0 that is only active while the device is in the S0
state.
Then, it performs a minor refactor by moving around switch statements
into their own functions, in order to allow for fixing the pwm1_enable ABI
in the final patch. Currently, pwm1_enable sets the fan to auto with the
value 0 and allows manual control with the value 1. This patch makes it
so 0 sets the fan to full speed, 1 sets the fan to manual control, and
2 sets the fan to auto. This requires both setting enable and the fan
speed when the enable sysfs is written to as 0, hence the refactor.
As this is a breaking ABI change and there is userspace software relying
on this previous behavior, the last patch also changes the /name of the
hwmon endpoint to "oxp_ec" from "oxpec" (mirroring WMI module conventions)
such that userspace software that relied on the previous behavior can be
retrofit to the new kernel while enabling correct functionality on old
and new kernels. Failing that, software that is not updated will just
stop controlling the fans, ensuring no malignant behavior.
Finally, the oxp-sensors module is converted into the oxpec platform driver
in order for it to stay as a single unit. Then, the appropriate
documentation for it is added.
Changes since V1:
- Add X1 Pro, F1 Pro variants
- Fix minor typo in initial patches
- Convert oxp-sensors into a platform driver, as it is no longer
considered a hwmon driver.
- Add sysfs documentation and myself to the MAINTAINERS file
- Update documentation to state that this is the OneXPlayer/AOKZOE
platform driver, and that support for Ayaneo/OPI is provided until
they gain their own platform driver.
