From 721a09f7393de6c28a07516dccd654c6e995944a Mon Sep 17 00:00:00 2001 From: Maarten Lankhorst Date: Tue, 15 Sep 2015 14:28:54 +0200 Subject: [PATCH] drm/i915: Add primary plane to mask if it's visible This fixes the warnings like "plane A assertion failure, should be disabled but not" that on the initial modeset during boot. This can happen if the primary plane is enabled by the firmware, but inheriting it fails because the DMAR is active or for other reasons. Most likely caused by commit 36750f284b3a4f19b304fda1bb7d6e9e1275ea8d Author: Maarten Lankhorst Date: Mon Jun 1 12:49:54 2015 +0200 drm/i915: update plane state during init Reported-by: Andreas Reis Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=91429 Reported-and-tested-by: Emil Renner Berthing Tested-by: Andreas Reis Reviewed-by: Daniel Vetter Signed-off-by: Jani Nikula --- drivers/gpu/drm/i915/intel_display.c | 7 +++++-- 1 file changed, 5 insertions(+), 2 deletions(-) diff --git a/drivers/gpu/drm/i915/intel_display.c b/drivers/gpu/drm/i915/intel_display.c index 8cc9264f7809..cf418be7d30a 100644 --- a/drivers/gpu/drm/i915/intel_display.c +++ b/drivers/gpu/drm/i915/intel_display.c @@ -15087,9 +15087,12 @@ static void readout_plane_state(struct intel_crtc *crtc, plane_state = to_intel_plane_state(p->base.state); - if (p->base.type == DRM_PLANE_TYPE_PRIMARY) + if (p->base.type == DRM_PLANE_TYPE_PRIMARY) { plane_state->visible = primary_get_hw_state(crtc); - else { + if (plane_state->visible) + crtc->base.state->plane_mask |= + 1 << drm_plane_index(&p->base); + } else { if (active) p->disable_plane(&p->base, &crtc->base); -- 2.39.5
