A special mode of operation to achieve minimal performance variation by letting the user have the ability to provide the desired frequency to be set as the soft limit. The user can control the entry and exit to the mode via rocm-smi a mechanism to enter / exit performance determinism mode as below. Enter performance determinism mode: - hold a lock - write performance_determinism to power_dpm_force_performance_level - write input clk_freq to pp_dpm_sclk - release lock Exit performance determinism_mode: - hold a lock - write auto to power_dpm_force_performance_level - release lock Signed-off-by: Divya Shikre <DivyaUday.Shikre@amd.com> Change-Id: Ia24e27954cdf1c4337ffc83d8948fbdfaf4552d2
