Hi there. I have a headache with linux bug https://bugzilla.kernel.org/show_bug.cgi?id=153281 and i'm one from many others that still suffered from the described issue. Personally i was able to move forward a bit. In particular, 1) with a great soft that manipulates with fan speed ranges https://github.com/dominiksalvet/asus-fan-control/issues/43 i was able to understand how maximal mode is activated at very low level in the so-called embedded controller in addresses 0x0521 and 0x0522. 2) It seems i understand that there is another driver/hardware mode that activates maximal mode eternally. 3) I disassembled my dsdt tables and found no more destructive code that could change maximal mode back https://github.com/icegood/my_dsdts ================ So, i'm interest in people here who could help me cruising in kernel sources to understand who else can communicate with an embedded controller. For now, I'm interested how driver asus-nb-wmi registers it's controlling chipset to hwmon so /sys/devices/platform/asus-nb-wmi/hwmon/hwmon5 node is created.
From sensors i see that it is a asus-isa-0000 Adapter: ISA adapter cpu_fan: 1900 RPM temp1: +53.0°C
and i wonder how it registered. -- Kind regards, Sergey Ivanov
