Re: Fwd: ARM64: CPUIdle driver is not select any Idle state other then WFI

Yes, I checked your guess was correct. ``enter_state`` value equals to Zero.

``#cat /sys/devices/system/cpu/cpu*/cpuidle/state*/rejected``
0 ==> state_0 CPU(0)
0 ==> state_1 CPU(0)
0 ==> state_0 rejected values CPU(1)
600117 ==> state_1 increasing values CPU(1)

What do you mean by ``psci`` description ?

I have one node in the device  tree file.

psci {
     compatible = "arm,psci-1.0";
     method = "smc";
};

Please find some logs. I am not able to conclude much by seeing the below logs.

#dmesg | grep "PSCI"
psci: PSCIv1.1 detected in firmware.
psci: Using standard PSCI v0.2 function IDs

#dmesg | grep "SMC"
psci: SMC calling Convention v1.2
SMCCC: SOC_ID: ARCH_SOC_ID not implemented, skipping ....

#dmesg | grep "MIGRATE_INTO_TYPE"
psci: MIGRATE_INTO_TYPE not supported.
