From: Nicholas Kazlauskas <nicholas.kazlauskas@xxxxxxx> [Why] Dropping the entirety of dml2_policy_build_synthetic_soc_states exposes an issue for states that cannot be filled via bbox_overrides and rely on the default parameters that may or may not be present depending on the DM. For amdgpu_dm this results in missing parameters for most of the struct in higher states: - sr_exit_time_us - sr_enter_plus_exit_time_us - sr_exit_z8_time_us - sr_enter_plus_exit_z8_time_us - urgent_latency_pixel_data_only_us - urgent_latency_pixel_mixed_with_vm_data_us - urgent_latency_vm_data_only_us - dram_clock_change_latency_us - fclk_change_latency_us - usr_retraining_latency_us - writeback_latency_us - urgent_latency_adjustment_fabric_clock_component_us - urgent_latency_adjustment_fabric_clock_reference_mhz - dscclk_mhz - phyclk_mhz - phyclk_d18_mhz - phyclk_d32_mhz - use_ideal_dram_bw_strobe [How] Copy from the first state, applying a minimal policy to set max clocks for SOC independent values. Then copy the SOC dependent ones from the states modified by bbox_overrides.
