Bug ID: 218461
Summary: ASUS Expertbook B5302F - no s0 residency in s2idle

output of `s0ix-selftest-tool.sh -s`
I'm using Intel's S0ixSelftestTool (https://github.com/intel/S0ixSelftestTool/)
as I was getting seemingly high battery drain in sleep. I've had this happen on
Arch, Mint, Fedora (with the distros' kernels) and I'm currently running
OpenSUSE with vanilla kernel 6.7.3. I've set the severity to high as a feature
that I need for day-to-day use is broken.
According to the logs, the self-test can get the CPU into PC10 state, but the
logs state:
"Your system supports S0ix substates, but did not achieve the shallowest
s0i2.0"
Reproducible: Always
Steps to Reproduce:
1. Run `s0ix-selftest-tool.sh -s`
2. Check for s0 residency
Actual Results:
CPU Core C7 residency after S2idle is: 97.26
GFX RC6 residency after S2idle is:
CPU Package C-state 2 residency after S2idle is: 4.02
CPU Package C-state 3 residency after S2idle is: 1.50
CPU Package C-state 8 residency after S2idle is: 0.43
CPU Package C-state 9 residency after S2idle is: 1.37
CPU Package C-state 10 residency after S2idle is: 84.44
S0ix residency after S2idle is: 0.00
Your system supports S0ix substates, but did not achieve the shallowest s0i2.0
Here is the S0ix substates status:
Substate Residency
S0i2.0 0
S0i3.0 0
(...)
Did not detect the potential blockers from substate_requirements,
need to check substate_status_registers file for the advanced debug.
(...)
Your system south port controller power gating state is OK after 30 seconds
runtime check.
Expected Results:
Residency in one of the s0 states
