> [Impact]
> 
> On AMD Yellow Carp B0 platforms, S0i3 is still not working.
> 
> [Fix]
> 
> This denpends on a few fixes for kernel driver that are all either in
> v5.17-rc1 or in stable linux-5.1x.y, along with an already upstreamed
> dmcub firmware.
> 
> [Test Case]
> 
> On AMD RMT CRB board,
> 1. apply both kernel and firmware fixes
> 2. module blacklist amd_sfh as it's still under development,
> 3. trigger system suspend. Use power button to wake up the device.
> 4. check /sys/kernel/debug/amd_pmc/s0ix_stats, the values shall be non-zero
> 
> On without any of above, the board may not cut device power during suspend,
> and/or fail to resume and leaving a blank screen, and/or s0ix stats remain
> all zeros.
> 
> [Where problems could occur]
> 
> So far all the patches can be cleanly applied, and they're being
> progressively proposed to linux-stable.
> 
> [Other Info]
> 
> For kernel driver fixes, patches for both oem-5.14 and jammy are necessary;
> for firmware, that has been available in jammy branch but not yet released,
> so only Focal will be nominated.
