From Dave [1]: """ It was a mistake to introduce core/acpi.c and putting ACPI dependency on cxl_core when adding the extended linear cache support. """ Current implementation calls hmat_get_extended_linear_cache_size() of the ACPI subsystem. That external reference causes issue running cxl_test as there is no way to "mock" that function and ignore it when using cxl test. Instead of working around that using cxlrd ops and extensively expanding cxl_test code [1], just move HMAT calls out of the core module to cxl_acpi. Implement this by adding a @cache_size member to struct cxl_root_decoder. During initialization the cache size is determined and added to the root decoder object in cxl_acpi. Later on in cxl_core the cache_size parameter is used to setup extended linear caching.
