BUGS
-
The
sony
driver just parses integer values from the
acpi(4)
tree.
It could be more intelligent and parse other controls.
-
The
sysctl(8)
interface is not great.
The names of the
sysctl(8)
tree are not self-explanatory.
-
No validity checks are performed on the user input.
Playing with random values and/or unknown controls can harm your
machine.
-
The name of the driver is too generic.
