   cpufreq/amd-pstate-ut: Fix an "Uninitialized variables" issue 
(2024-09-11 10:53:03 -0500)

----------------------------------------------------------------
second round of amd-pstate changes for 6.12 (second try):

* Move the calculation of the AMD boost numerator outside of
   amd-pstate, correcting acpi-cpufreq on systems with preferred cores
* Harden preferred core detection to avoid potential false positives
* Add extra unit test coverage for mode state machine
 
 
 
 
----------------------------------------------------------------
Mario Limonciello (13):
       x86/amd: Move amd_get_highest_perf() from amd.c to cppc.c
       ACPI: CPPC: Adjust return code for inline functions in 
!CONFIG_ACPI_CPPC_LIB
       x86/amd: Rename amd_get_highest_perf() to 
amd_get_boost_ratio_numerator()
       ACPI: CPPC: Drop check for non zero perf ratio
       ACPI: CPPC: Adjust debug messages in amd_set_max_freq_ratio() to warn
       x86/amd: Move amd_get_highest_perf() out of amd-pstate
       x86/amd: Detect preferred cores in amd_get_boost_ratio_numerator()
       cpufreq: amd-pstate: Merge amd_pstate_highest_perf_set() into 
amd_get_boost_ratio_numerator()
       cpufreq: amd-pstate: Optimize amd_pstate_update_limits()
       cpufreq: amd-pstate: Add documentation for `amd_pstate_hw_prefcore`
       amd-pstate: Add missing documentation for 
`amd_pstate_prefcore_ranking`
       cpufreq/amd-pstate: Export symbols for changing modes
       cpufreq/amd-pstate-ut: Add test case for mode switches
