NAME
sony -- Sony Miscellaneous Controller SYNOPSIS
sony* at acpi? 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) SEE ALSO
acpi(4), spic(4) HISTORY
The sony driver appeared in NetBSD 4.0. AUTHORS
Sami Kantoluoto for the original driver and manual information. Christos Zoulas for cleaning up the driver and this manual page. BUGS
o The sony driver just parses integer values from the acpi(4) tree. It could be more intelligent and parse other controls. o The sysctl(8) interface is not great. The names of the sysctl(8) tree are not self-explanatory. o No validity checks are performed on the user input. Playing with random values and/or unknown controls can harm your machine. o The name of the driver is too generic. BSD
