[PATCH 7/8] amdgpu/pm: Optimize emit_clock_levels for aldebaran - part 2

Darren Powell darren.powell at amd.com
Thu Apr 27 06:27:17 UTC 2023


 Use variables to remove ternary expression in print statement
 and improve readability. This will help to optimize the code
 duplication in the switch statement
 Also Changed:
  replaced single_dpm_table->count as iterator in for loops
    with safer clocks_num_levels value
  replaced dpm_table.value usage with local var clocks_mhz
