30*0Sstevel@tonic-gate * This file contains code for setting up environmental related nodes
31*0Sstevel@tonic-gate * and properties in the PICL tree.
32*0Sstevel@tonic-gate *
33*0Sstevel@tonic-gate * For each temperature-device class node, it does the following:
34*0Sstevel@tonic-gate * - Create cpu and cpu-ambient temperautre-sensor class nodes.
35*0Sstevel@tonic-gate * - Create "devfs-path" property under each temperature-sensor class node
36*0Sstevel@tonic-gate * - Create "Temperature" volatile property under these nodes.
37*0Sstevel@tonic-gate * - Create various temperature threshold properties under each node.
38*0Sstevel@tonic-gate * - Create "Temperature" and "AmbientTemperature" volatile properties
39*0Sstevel@tonic-gate * under corresponding "cpu" class node.
40*0Sstevel@tonic-gate *
41*0Sstevel@tonic-gate * For the "fan-control" node, it does the following:
42*0Sstevel@tonic-gate * - Create system-fan node
43*0Sstevel@tonic-gate * - Create "devfs-path" property under "fan" class node
44*0Sstevel@tonic-gate * - Create "Speed" volatile propery under each node.
45*0Sstevel@tonic-gate * - Create "SpeedUnit" property under each node.
46*0Sstevel@tonic-gate *
47*0Sstevel@tonic-gate * Access to sensor/fan properties is protected by the envpicl_rwlock
48*0Sstevel@tonic-gate * readers/writer lock. This lock is held as a reader while trying to
49*0Sstevel@tonic-gate * access any volatile sensor/fan property, and held as a writer lock
50*0Sstevel@tonic-gate * while trying to create or destroy sensor/fan nodes and properties.
