We need to calculate cdclk after watermarks/ddb has been calculated as with recent hw CDCLK needs to be adjusted accordingly to DBuf requirements, which is not possible with current code organization. Setting CDCLK according to DBuf BW requirements and not just rejecting if it doesn't satisfy BW requirements, will allow us to save power when it is possible and gain additional bandwidth when it's needed - i.e boosting both our power management and perfomance capabilities. This patch is preparation for that, first we now extract modeset calculation from modeset checks, in order to call it after wm/ddb has been calculated. v2: - Extract only intel_modeset_calc_cdclk from intel_modeset_checks (Ville Syrjälä) v3: - Clear plls after intel_modeset_calc_cdclk v4: - Added r-b from previous revision to commit message Reviewed-by:
