acpi.c

Many recent AMD SoCs need to have their NVMe placed into D3cold at suspend time to properly resume. Other machines break when we do that. To solve this dilemma, Microsoft introduced a "StorageD3Enable" ACPI property that tells us what to do. Note that despite its name, this property seems to be relevant for PCI devices that aren't storage related as well.

acpidev.h

Some laptops will generate an EC event shortly after we attempt to enter a low power S0 idle state. Since we register the EC GPE as a wakeup GPE this means we'll wake up immediately. Unfortunately we have to register that GPE as a wakeup GPE otherwise many laptops won't wake up when the user opens the lid (and some laptops won't wake up at all). So add some code to handle EC events while suspended and introduce the concept of wakeup AML notify handlers. Register the acpibtn(4) notify handlers as wakeup notify handlers such that we wake up. We'll go back to sleep immediately if we wake up for any other EC event.

Revert the guts of rev 1.14. This ends up attempting to turn of power resources for devices that aren't present. And that makes us run AML that clearly hasn't been tested by the vendors. And on my test laptop this no longer seems to make a meaningful difference in the power consumption during suspend-to-idle.

Make the Samsung Galaxy Book4 Edge (x1e80100) boot in ACPI mode; Until now the kernel did panic during early boot because we couldn't respond to the battery requests sent to the 0xa1 "bus". This (dummy) driver registers a 0xa1 region space very early, and responds with a static zero value to satisfy the battery requests on 0xa1, which let us boot successfully to multi-user.
