Hi Rafael, Mario,

Stephen is having an issue with a recent AMD laptop (a Lenovo Ideapad model)
where Linux defaults to using S3/deep suspend instead of S0ix/s2idle.

This is causing the sensors provided by the AMD Sensor Fusion Hub
to stop working after a suspend/resume. Adding mem_sleep_default=s2idle
to the kernel commandline fixes this.

Do you have any idea what might be causing this ?

Regards,

Hans

Thanks Stephen MacNeil,

On our hardware we do not see any amd_sfh issue with 5.14.0-rc2 kernel.
 
Could you please check with Lenovo, as we are not observing amd_sfh issue on our reference platforms too.

Thanks,
Basavaraj
<<
looking at the information I sent him  i looks like the issue is (to me anyway)

cat /sys/power/mem_sleep
[s2idle] deep

without
cat /sys/power/mem_sleep
s2idle [deep]


this is the info he requested... any idea who else I can contact.
this is the output with and without the kernel param

 

Thanks a lot Stephen MacNeil  for the information.

 

Could you please provide me below information:-

·  what version of kernel is running.

uname -a
Linux ideapad 5.14.0-051400rc2-generic #202107182230 SMP Sun Jul 18 22:34:12 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux


·  Are you using latest patches from amd-sfh

only the kernel

·  Could you please provide me output of /sys/power/mem_sleep

with kernel option mem_sleep_default=s2idle

cat /sys/power/mem_sleep
[s2idle] deep

without
cat /sys/power/mem_sleep
s2idle [deep]

·  Could you please provide output of below script after installing “apt install iasl*”. acpica-tools

with kernel option mem_sleep_default=s2idle
