.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver provides support for the
|
|
.Tn Microchip Technology
|
|
MCP9805/98242 and other chips that conform to JEDEC Standard 21-C section
|
|
4.7.
|
|
Memory module temperature sensors are optional on DDR2 and DDR3 SDRAM DIMMs.
|
|
Sensors provided by this driver, including the on-chip thresholds for the
|
|
Alarm Window and Critical level, are accessed through the
|
|
.Xr envsys 4
|
|
API.
|
|
