Mario Limonciello b79276dcac ACPI: processor: Move arch_init_invariance_cppc() call later ... arch_init_invariance_cppc() is called at the end of acpi_cppc_processor_probe() in order to configure frequency invariance based upon the values from _CPC. This however doesn't work on AMD CPPC shared memory designs that have AMD preferred cores enabled because _CPC needs to be analyzed from all cores to judge if preferred cores are enabled. This issue manifests to users as a warning since commit 21fb59ab4b ("ACPI: CPPC: Adjust debug messages in amd_set_max_freq_ratio() to warn"): ``` Could not retrieve highest performance (-19) ``` However the warning isn't the cause of this, it was actually commit 279f838a61 ("x86/amd: Detect preferred cores in amd_get_boost_ratio_numerator()") which exposed the issue. To fix this problem, change arch_init_invariance_cppc() into a new weak symbol that is called at the end of acpi_processor_driver_init(). Each architecture that supports it can declare the symbol to override the weak one. Define it for x86, in arch/x86/kernel/acpi/cppc.c, and for all of the architectures using the generic arch_topology.c code.
