Jean, do you think one can write an acpi-hwmon driver with such provided ACPI functions to read/write fan and temp?
Yes, but it will be difficult. There was an attempt to do this for some Asus motherboards: http://lists.lm-sensors.org/pipermail/lm-sensors/2007-May/019715.html My fear is that this will be heavily motherboard-dependent. We will have to check the DSDT of every motherboard out there to find out which AML methods do what. Not only the function names with vary from one board to the next, but also the calling convention, possible side effects and even availability of these functions. Even a simple BIOS update could break it. This is something we always tried to avoid with non-ACPI hardware monitoring drivers, because it doesn't scale at all over time and makes maintenance a nightmare. But of course, if your plan is really to get rid of all SMBus master and hardware monitoring drivers as soon as ACPI is enabled, then you will have to do something like that. You simply can't kill a functionality thousands of people have been using for years without providing something to replace it. That something will lack some (most?) of the features (for example ACPI doesn't care about voltages at all, does it?) but at the very least it must exist. Otherwise, expect receiving hundred mails from angry users every month. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
