Sorry, I just re-read and saw that this will be in sclk and mclk, not just mclk. So will this have a direct impact on any other functionality, or will it just disable clock/power gating and prevent the clocks from changing?

So just to make sure that I understand this correctly, if a user were to echo P to the pp_dpm_mclk file, it would disable clockgating and powergating and keep the memory clocks at a stable level (likely level 0)? And this would have no impact on the SCLK or Power Profile or anything else, just the mclk? Just asking so I know how to implement it in the SMI. Thanks!

What is it used for? This is used for the profiling stuff in force_performance_level. It disables clock and power gating and sets stable clock levels for doing performance profiling.
