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: Ville Syrjälä Signed-off-by: Stanislav Lisovskiy --- drivers/gpu/drm/i915/display/intel_display.c | 22 +++++++++++--------- 1 file changed, 12 insertions(+), 10 deletions(-) diff --git a/drivers/gpu/drm/i915/display/intel_display.c b/drivers/gpu/drm/i915/display/intel_display.c index fd6d63b03489..3bf6751497c8 100644 --- a/drivers/gpu/drm/i915/display/intel_display.c +++ b/drivers/gpu/drm/i915/display/intel_display.c @@ -14493,12 +14493,6 @@ static int intel_modeset_checks(struct intel_atomic_state *state) return ret; } - ret = intel_modeset_calc_cdclk(state); - if (ret) - return ret; - - intel_modeset_clear_plls(state); - if (IS_HASWELL(dev_priv)) return hsw_mode_set_planes_workaround(state); @@ -14830,10 +14824,6 @@ static int intel_atomic_check(struct drm_device *dev, goto fail; } - ret = intel_atomic_check_crtcs(state); - if (ret) - goto fail; - intel_fbc_choose_crtc(dev_priv, state); ret = calc_watermark_data(state); if (ret) @@ -14843,6 +14833,18 @@ static int intel_atomic_check(struct drm_device *dev, if (ret) goto fail; + if (any_ms) { + ret = intel_modeset_calc_cdclk(state); + if (ret) + return ret; + + intel_modeset_clear_plls(state); + } + + ret = intel_atomic_check_crtcs(state); + if (ret) + goto fail; + for_each_oldnew_intel_crtc_in_state(state, crtc, old_crtc_state, new_crtc_state, i) { if (!needs_modeset(new_crtc_state) &&
