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.
