Re: [RFC v1 0/8] acpi/x86: s2idle: Introduce and implement runtime standby ABI for ACPI s0ix platforms

[Antheas Kapenekakis]

Hi everyone,
now that the kernel merge window is over, I will slowly get back to
cleaning this series up

I already have some feedback that I will address with V2.

Specifically, we found out that the resume DSM needs to always be
called and it merged with 7.0. So I will rebase on top of it, remove
the patch that added it, and rework the logic to always call resume
before sleep exit. I am not sure how I will tackle this or whether it
will involve reshaping the FSM states.

Then, there was a compilation warning reported by the kernel bot.

Afterwards, I reviewed the feedback in the Phoronix article. People
would like to have an option to turn this feature off, or perhaps
force it off. We could add a Y/n Kconfig for the sysfs patch
defaulting to Y that enables it, which will be the appropriate option
for consumer kernels. Or a kernel command line parameter so that users
do not need to produce their own kernel.

Finally, there is the issue of the Ally devices, which will need a
partial cleanup that needs to go through platform-x86 and hid core,
which would make this series touch 3 subsystems. I would tend towards
omitting it for V2 to keep a short(er) cc list, but I can produce it
for testing as an addendum.

I have my plate full for the next week, so if you would like for me to
consider some feedback, next week would be a good time to review this
series.

Best,
Antheas
