This series wraps Dave Jiang's v4 with tests as per v2. The kernel code using this is now at v10 and reflects the changes made here.

Thanks to all involved. Changes since v4: - Add updated bios table to reflect the changs made in v3/v4 Based-on: qemu/master a51e5124a6 Key thing to note vs V2 is that this now returns a package of integers and the example returns a package with two elements in it. This corresponds to a firmware saying that for any input parameters the QTGs should be used in order of preference 0 then 1. As per patch 2 description: Add a simple _DSM call support for the ACPI0017 device to return fake QTG ID values of 0 and 1 in all cases. This for _DSM plumbing testing from the OS. Following edited for readability Device (CXLM) { Name (_HID, "ACPI0017") // _HID: Hardware ID ...
