BUGS
- The
sonydriver 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.
