aibs(4): ASUSTeK AI Booster (ACPI ATK0110) Hardware Monitor

[Constantine A. Murenin]

Dear freebsd-{acpi,drivers,hardware}@, 


Attached patch provides support for the hardware monitoring capabilities 
that are present in many modern desktop motherboards from ASUS featuring 
the ATK0110 ACPI device. 


This driver, aibs(4), is a fresh replacement for FreeBSD's existing 
acpi_aiboost(4).  The new aibs(4) driver has the following advantages 
when compared to the old acpi_aiboost(4): 

* the sensors are now provided through the user-serviceable hw.acpi.aibs0 
  tree (with a subtree for each sensor type), instead of the Newbus-internal 
  dev.acpi_aiboost.0 tree that contains various nonprime data at the same 
  level as the actual sensors 

* the supposed range specifications are now reported 
  for each input that is being sensed 

* the nature of the new tree, with "volt", "temp" and "fan" subtrees, 
  allows one to specifically query for the sensors of a certain type 

* the temperature sensors are exported in the temperature 'K' units through 
  sysctl(9), such that they are pretty-printed by sysctl(8) automatically 

* more user documentation is provided 


It is expected that aibs(4) should replace any and all functionality 
previously provided by acpi_aiboost(4), provide additional features as 
specified above and decrease the size of both the source and the binary 
code.  Please find the demonstration below.
