But since there is still a state swap for that CRTC, the current PLL assignment needs to be preserved. I missed the ddi_pll_sel field in the following commit, which causes warnings in DDI platforms. commit 4978cc93d9ac240b435ce60431aef24239b4c270 Author: Ander Conselvan de Oliveira Date: Tue Apr 21 17:13:21 2015 +0300 drm/i915: Preserve shared DPLL information in new pipe_config Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=90410 Signed-off-by: Ander Conselvan de Oliveira Reviewed-by: Damien Lespiau Signed-off-by: Daniel Vetter --- diff --git a/drivers/gpu/drm/i915/intel_display.c b/drivers/gpu/drm/i915/intel_display.c index 620fdd8077dd..24f9b3fc6d80 100644 --- a/drivers/gpu/drm/i915/intel_display.c +++ b/drivers/gpu/drm/i915/intel_display.c @@ -11490,12 +11490,14 @@ clear_intel_crtc_state(struct intel_crtc_state *crtc_state) struct intel_crtc_scaler_state scaler_state; struct intel_dpll_hw_state dpll_hw_state; enum intel_dpll_id shared_dpll; + uint32_t ddi_pll_sel; /* Clear only the intel specific part of the crtc state excluding scalers */ tmp_state = crtc_state->base; scaler_state = crtc_state->scaler_state; shared_dpll = crtc_state->shared_dpll; dpll_hw_state = crtc_state->dpll_hw_state; + ddi_pll_sel = crtc_state->ddi_pll_sel; memset(crtc_state, 0, sizeof *crtc_state); @@ -11503,6 +11505,7 @@ clear_intel_crtc_state(struct intel_crtc_state *crtc_state) crtc_state->scaler_state = scaler_state; crtc_state->shared_dpll = shared_dpll; crtc_state->dpll_hw_state = dpll_hw_state; + crtc_state->ddi_pll_sel = ddi_pll_sel; } static int
