CPU idle time management (CPUIdle) drivers provide an interface between the other parts of CPUIdle and the hardware. First of all, a CPUIdle driver has to populate the states array of struct cpuidle_state objects included in the struct cpuidle_driver object representing it. Going forward this array will represent the list of available idle states that the processor hardware can be Estimated Reading Time: 12 mins. intel_idle_cpuidle_driver_init (intel_idle_driver); retval = cpuidle_register_driver (intel_idle_driver); if (retval) {struct cpuidle_driver *drv = cpuidle_get_driver (); printk (KERN_DEBUG pr_fmt (" intel_idle yielding to %s \n "), drv? drv- name: " none "); goto init_driver_fail;} retval = cpuhp_setup_state (CPUHP_AP_ONLINE_DYN, " idle/intel:online ".

CPU idle time management (CPUIdle) drivers provide an interface between the other parts of CPUIdle and the hardware. First of all, a CPUIdle driver has to populate the states array of struct cpuidle_state objects included in the struct cpuidle_driver object representing it. Going forward this array will represent the list of available idle states that the processor hardware can be asked to enter shared by all of the logical CPUs handled by the given driver. intel_idle_cpuidle_driver_init (intel_idle_driver); retval = cpuidle_register_driver (intel_idle_driver); if (retval) {struct cpuidle_driver *drv = cpuidle_get_driver (); printk (KERN_DEBUG pr_fmt (" intel_idle yielding to %s "), drv? drv- name: " none "); goto init_driver_fail;} retval = cpuhp_setup_state (CPUHP_AP_ONLINE_DYN, " idle/intel:online ". intel_idle is a part of the CPU idle time management subsystem in the Linux kernel (CPUIdle). It is the default CPU idle time management driver for the Nehalem and later generations of Intel processors, but the level of support for a particular processor model in it depends on whether or not it recognizes that processor model and may also depend on information coming from the platform firmware.

২০ নভেম্বর, ২০১৭ Short Answer: Both are different implementations of CPU idle drivers. acpi_idle is the default driver, supports all CPU architectures. 22 * intel_idle is a cpuidle driver that loads on specific Intel processors 83 static unsigned int lapic_timer_reliable_states = (1 << 1); /* Default to. ২৬ জুন, ২০১৯ -EBUSY) pr_err("Failed to register cpuidle driver\n"); goto CPU idle Driver" selected - compiles and runs but same errors and "none" for.
