@yinghany, I believe you should be the owner?
@yinghany Is there any plan to support PRM sample? Thanks.
@guliteb The public direct-call interface has been revamped/simplified as part of the next Windows release. Documentation/samples around this interface will be coordinated with the OS release. We will have more information closer to the release date.
@yinghany Is there any update on PRM driver sample? Do you have an estimation of the target timeline? Thanks.
PRM is a feature that allows a subset of platform firmware code to move out of SMM and execute in OS context.
Support for a new PRM OpRegion type was added to the ACPI 6.4 Specification.
Functionality in PRM modules can be invoked via the "ACPI-specification defined interface" using the PRM OpRegion or through a "direct interface". While the former is documented in the ACPI Specification, the latter needs sample code.
This issue tracks the addition of that sample code to this repo.
