thermal: intel: int3400: clean up ODVP on probe failures

2026-07-22T14:45:36+00:00

evaluate_odvp() creates per-ODVP sysfs files before the thermal zone and later probe resources are registered. The current unwind path only calls cleanup_odvp() from the late sysfs failure path, so failures after evaluate_odvp() but before that label, including thermal_tripless_zone_device_register() failures, leave the ODVP files and storage behind. Move the ODVP cleanup to the common ART/TRT unwind path so every failure after evaluate_odvp() releases the ODVP state. Also clear the cached ODVP pointers in cleanup_odvp(), because evaluate_odvp() can already call it for partial setup failures while probe continues.

thermal: intel: int340x: clean up RFIM groups on DVFS failure

2026-07-22T13:32:39+00:00

proc_thermal_rfim_add() can create the FIVR and DLVR sysfs groups before creating the DVFS group. If DVFS group creation fails while both earlier groups are enabled, the current error handling removes only one group: the FIVR branch returns before the DLVR cleanup branch can run. This leaves the DLVR group behind even though RFIM setup fails. Use one DVFS failure path that removes all previously created RFIM groups before returning the error.

thermal: intel: Add a syscore shutdown callback for kexec reboot

2026-07-14T19:31:02+00:00

A kexec reboot may load a kernel that does not support directed package- level thermal interrupts. Without a shutdown callback, the directed interrupt configuration remains enabled across kexec but will not be handled correctly. In particular, if the CPU designated to receive the directed interrupt goes offline, no other CPU in the package will receive it. Add a syscore shutdown callback to disable directed package-level thermal interrupts on all packages before a kexec reboot. If the post-kexec kernel does not enable directed interrupts, it falls back to broadcasting the interrupt to all CPUs.

thermal: intel: Add syscore callbacks for suspend and resume

2026-07-14T19:31:02+00:00

Directed package-level thermal interrupts are serviced by a single CPU per package. These handler CPUs are selected at boot through the CPU hotplug infrastructure. This mechanism is sufficient to restore the directed interrupt configuration when resuming from suspend for non-boot packages. It also keeps the handler-tracking array updated. For the boot package, CPU0 is chosen during boot because its CPU hotplug online callback runs first. However, this callback is not invoked on resume. The directed package-level interrupt configuration for the boot package is not restored. Add a syscore resume callback to re-enable directed package-level interrupts for this package. Disabling directed interrupts during suspend is required to keep the handler-tracking array in a consistent state for the boot package, allowing the correct configuration to be restored on resume. The resume callback must busy-wait for hardware acknowledgment of the directed interrupt setup. Otherwise, the handler-tracking array could be left in an inconsistent state. This implies running with interrupts disabled for up to 15ms, though in practice it takes less than 1ms.
