Hi, Peter, I'm sorry to bother you, but commit 6e1d2bc675bd57640f5658a4a657ae488db4c204 ("intel_idle: Fix intel_idle() vs tracing") broke my build, when CONFIG_ACPI_PROCESSOR is disabled (possibly because it selects CONFIG_ACPI_PROCESSOR_IDLE):
drivers/idle/intel_idle.c: In function ‘intel_idle_init_cstates_icpu’: drivers/idle/intel_idle.c:1510:7: error: implicit declaration of function ‘intel_idle_state_needs_timer_stop’ [-Werror=implicit-function-declaration] 1510 | if (intel_idle_state_needs_timer_stop(&drv->states[drv->state_count])) | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Reverting the aforementioned commit fixes it. Config attached. Please let me know if you need anything else! Thanks, Rui
