The string conversion frunctions provided by the WMI driver core
have no dependencies on the remaining WMI API, making them suitable
for unit tests.

Implement such a unit test using kunit. Those unit tests verify that
converting between WMI strings and UTF8 strings works as expected.
They also verify that edge cases are handled correctly.

platform/wmi: Add kunit test for the marshalling code 2026-01-20T13:47:49+00:00 Armin Wolf W_Armin@gmx.de 2026-01-16T20:41:09+00:00 29dfba69c3ddb7945cd772042c6a9ce770c1ba22 The marshalling code used by the WMI driver core is implemented as a separate component, suitable for unit tests. Implmented such a unit test using KUnit. Those unit tests verify that ACPI objects are correctly converted into WMI buffers and that WMI strings are correctly converted into ACPI strings. They also verify that invalid ACPI data (like nested packages) is rejected.
