Hi All,
On top of the "Simplify the suspend-to-idle control flow" patch series
posted previously:
https://lore.kernel.org/lkml/71085220.z6FKkvYQPX@kreacher/
sanitize the suspend-to-idle flow even further.
First off, decouple EC wakeup from the LPS0 _DSM processing (patch 1).
Next, reorder the code to invoke LPS0 _DSM Functions 5 and 6 in the
specification-compliant order with respect to suspending and resuming
devices (patch 2).
Finally, rearrange lps0_device_attach() (patch 3) and add a command line
switch to prevent the LPS0 _DSM from being used.
The v2 is because I found a (minor) bug in patch 1, decided to use a module
parameter instead of a kernel command line option in patch 4. Also, there
are 4 new patches:
Patch 5: Switch the EC over to polling during "noirq" suspend and back
during "noirq" resume.
Patch 6: Eliminate acpi_sleep_no_ec_events().
Patch 7: Consolidate some EC code depending on PM_SLEEP.
Patch 8: Add EC GPE dispatching debug message.
The v3 is just a rearranged v2 so as to move the post sensitive patch (previous patch 2)
to the end of the series. [After applying the full series the code is the same as before.]
For easier testing, the series (along with some previous patches depended on by it)
is available in the pm-s2idle-testing branch of the linux-pm.git tree at kernel.org:
https://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git/log/?h=pm-s2idle-testing
Please refer to the changelogs for details.
I have tested both pm-s2idle-testing and pm-s2idle-rework branches
including recently introduced commit "PM: suspend: Fix
platform_suspend_prepare_noirq()".
Works fine for me on Ice Lake platform.
