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.
