The userspace governor is still in use on production systems and the
deprecating warning is scary.
Even if we want to get rid of the userspace governor, it is too soon
yet as the alternatives are not yet adopted.
Change the deprecated warning by an information message suggesting to
switch to the netlink thermal events.
Fixes: 0275c9fb0e ("thermal/core: Make the userspace governor deprecated")

help
|
|
Thermal drivers offer a generic mechanism for
|
|
thermal management. Usually it's made up of one or more thermal
|
|
zones and cooling devices.
|
|
Each thermal zone contains its own temperature, trip points,
|
|
and cooling devices.
|
|
All platforms with ACPI or Open Firmware thermal support can use
|
|
this driver.
|
|
If you want this support, you should say Y here.

Thermal subsystem will issue a graceful shutdown when

|
critical temperatures are reached using orderly_poweroff(). In
|
|
case of failure of an orderly_poweroff(), the thermal emergency
|
|
poweroff kicks in after a delay has elapsed and shuts down the system.
|
|
This config is number of milliseconds to delay before emergency
|
|
poweroff kicks in. Similarly to the critical trip point,
|
|
the delay should be carefully profiled so as to give adequate
|
|
time for orderly_poweroff() to finish on regular execution.
|
|
If set to 0 emergency poweroff will not be supported.

In doubt, leave as 0.
