   cpufreq/amd-pstate-ut: Add fix for min freq unit test (2024-10-22 
15:21:42 -0500)

----------------------------------------------------------------
Update the amd-pstate driver to set the initial scaling frequency policy
lower bound to be lowest non-linear frequency. This will have a slight
power consumption impact but should lead to increased efficiency.

Also amd-pstate is enabled by default on servers starting with newer
AMD Epyc processors.

Add various code cleanups to rename functions and remove redundant calls.

----------------------------------------------------------------
Dhananjay Ugwekar (7):
       cpufreq/amd-pstate: Rename MSR and shared memory specific functions
       cpufreq/amd-pstate: Remove the redundant verify() function
       cpufreq/amd-pstate: Set the initial min_freq to lowest_nonlinear_freq
       cpufreq/amd-pstate: Call amd_pstate_register() in amd_pstate_init()
       cpufreq/amd-pstate: Call amd_pstate_set_driver() in 
amd_pstate_register_driver()
       cpufreq/amd-pstate: Remove the switch case in amd_pstate_init()
       cpufreq/amd-pstate: Remove the redundant amd_pstate_set_driver() call

Gautham R. Shenoy (1):
       amd-pstate: Set min_perf to nominal_perf for active mode 
performance gov

Mario Limonciello (5):
       cpufreq/amd-pstate: Fix non kerneldoc comment
       cpufreq/amd-pstate: Don't update CPPC request in 
amd_pstate_cpu_boost_update()
       cpufreq/amd-pstate: Use amd_pstate_update_min_max_limit() for EPP 
limits
       cpufreq/amd-pstate: Drop needless EPP initialization
       cpufreq/amd-pstate-ut: Add fix for min freq unit test

Swapnil Sapkal (1):
       amd-pstate: Switch to amd-pstate by default on some Server platforms

Thanks!  I'll send you a new PR later this week so I can pick up the 
other fixes still under discussion.
