Does the ACPI subsystem allow to track, how ACPI variables(?) like IOST
are read and set?

My guess would be that IOST is a field in an operation region which
would indicate that it is initialized by the bootstrap part of the
BIOS.

Thank you for your answer. But how can I verify that? Is there a Linux
kernel parameter, that would print it?
Kind regards,

Inspecting the ACPI tables from the system in question could help you
to find out whether or not IOST really is a field in an operation
region, but its initial value may not be possible to determine this
way.

Not that I know of.

I created an issue in the Linux kernel bugtracker [1] and attached the
output of `acpidump` there.
Could
If ((IOST & 0x4000))
versus
If ((IOST & 0x0400))
be a typo?
