thermal: core: Suspend thermal zones later and resume them earlier

2026-04-08T10:30:31+00:00

To avoid some undesirable interactions between thermal zone suspend and resume with user space that is running when those operations are carried out, move them closer to the suspend and resume of devices, respectively, by updating dpm_prepare() to carry out thermal zone suspend and dpm_complete() to start thermal zone resume (that will continue asynchronously). This also makes the code easier to follow by removing one, arguably redundant, level of indirection represented by the thermal PM notifier. Signed-off-by: Rafael J. Wysocki Reviewed-by: Armin Wolf Link: https://patch.msgid.link/2036875.PYKUYFuaPT@rafael.j.wysocki

thermal: core: Allocate thermal_class statically

2026-04-08T10:30:31+00:00

Define thermal_class as a static structure to simplify thermal_init() and to simplify thermal class availability checks that will need to be carried out during the suspend and resume of thermal zones after subsequent changes.

The thermal workqueue doesn't need to be freezable or per-CPU, so drop WQ_FREEZABLE and WQ_PERCPU from the flags when allocating it. No intentional functional impact. Signed-off-by: Rafael J.
