DESCRIPTION
Some Sony notebook computers have a controller that handles various built-in devices. The sony driver provides support for accessing/modify- ing the settings of some of these devices via the sysctl(8) interface. The following sysctl(8) variables are available: hw.sony0.brt [R/W] Controls current LCD brightness. Range [0-8]. hw.sony0.pbr [R/W] Controls power on LCD brightness. Range [0-8]. hw.sony0.cdp [R/W] Controls CD power. hw.sony0.pid [R/O] Unknown hw.sony0.ctr [R/W] Unknown hw.sony0.pcr [R/W] Unknown hw.sony0.cmi [R/W] Unknown hw.sony0.ams [R/W] Audio control (mute when 0) hw.sony0.hke [R/O] Indicates a Host Key Event. Bits are set when an event occurs and cleared when this value is read. The following table describes the bit set for each button pressed: 0x1000 S1 button 0x0800 S2 button 0x0200 Fn + F10 (magnify) 0x0100 Mute button 0x0020 Fn + F12 (suspend to disk) 0x0010 Fn + F7 (LCD/external monitor) 0x0008 Fn + F6 (brighter backlight) 0x0004 Fn + F5 (darker backlight) 0x0002 Fn + F4 (volume up) 0x0001 Fn + F3 (volume down)

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. NetBSD 10.0 August 25, 2020 NetBSD 10.0
