NAME
g760a —
Global Mixed-mode Technology
Inc. G760a fan speed controller driver
SYNOPSIS
g760a0 at iic? addr 0x3e
DESCRIPTION
The
g760a driver provides support for the Global Mixed-mode
Technology Inc. G760a on iicbus fan speed controller to be used with the
envsys(4) API. This chip could
be found in D-Link's DNS-323 NAS box.
The following
sysctl(8) variable
controls the fan's speed:
-
-
machdep.g760a0.rpm
- This value specifies the desired speed for the fan. Valid
range is 2000..20000 or 0 (the fan is turned off). The default value is 0.
When setting the desired speed the RPM number will be converted to the
internal representation and truncated. For example when you are setting
2000 it will be truncated to 2006, and 8000 will be changed to 8057.
