This isn't the case atm, since after the encoder changes adjusted_mode to fixed mode the crtc_* timing fields of adjusted_mode will stay at their original non-native values that the user passed in. This results in a corrupted output. One exception is when we have a second pass of computing encoder configs due to bandwidth limitation, since then we'll set adjusted_mode.crtc_* fields to the fixed mode values set in the first pass; so in this case things will work out. Fix this by updating the adjusted_mode.crtc_* fields when we set the fixed panel mode. This regression has been introduced in commit 135c81b8c3c9a70d7b55758c9c2a247a4abb7b64 Author: Daniel Vetter Date: Sun Jul 21 21:37:09 2013 +0200 drm/i915: clean up crtc timings computation Signed-off-by: Imre Deak Reviewed-by: Mika Kuoppala Signed-off-by: Daniel Vetter --- diff --git a/drivers/gpu/drm/i915/intel_panel.c b/drivers/gpu/drm/i915/intel_panel.c index a43c33bc4a35..913cb9d7fd32 100644 --- a/drivers/gpu/drm/i915/intel_panel.c +++ b/drivers/gpu/drm/i915/intel_panel.c @@ -50,6 +50,8 @@ intel_fixed_panel_mode(struct drm_display_mode *fixed_mode, adjusted_mode->vtotal = fixed_mode->vtotal; adjusted_mode->clock = fixed_mode->clock; + + drm_mode_set_crtcinfo(adjusted_mode, 0); } /* adjusted_mode has been preset to be the panel's fixed mode */
