---Check S2idle path S0ix Residency---:

The system OS Kernel version is:
Linux hostname 6.9.12-200.fc40.x86_64 #1 SMP PREEMPT_DYNAMIC Sat Jul 27 15:56:15 UTC 2024 x86_64 GNU/Linux

---Check whether your system supports S0ix or not---:

Low Power S0 Idle is:1
Your system supports low power S0 idle capability.



---Check whether intel_pmc_core sysfs files exit---:

The pmc_core debug sysfs files are OK on your system.



---Judge PC10, S0ix residency available status---:

Test system supports S0ix.y substate

S0ix substate before S2idle:

Need to debug why not deeper substate: S0i2.2

---Begin S0ix Substate Debug by substate_requirements---:

Clear lpm_latch_mode is Done

Set S0i2.1 to lpm_latch_mode is Done

Need to run once S2idle, please wait for 15 seconds...
