From 11f489d3c62b1e55efbc5f1ab058d85851a96d0e Mon Sep 17 00:00:00 2001 From: Mahesh Kumar Date: Fri, 30 Jun 2017 17:40:59 +0530 Subject: [PATCH] drm/i915/skl+: Check for supported plane configuration in Interlace mode MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit In Gen9 platform Interlaced fetch mode doesn't support following plane configuration: - Y/Yf tiling - 90/270 rotation - YUV420 hybrid planar source pixel formats. This patch adds check to fail the flip if any of the above configuration is requested. Changes since V1: - handle checks in intel_plane_atomic_check_with_state (ville) - takeout plane scaler checks combile with pipe scaler in next patch Changes since V2: - No need to check for NV12 as it need scaling, so it will be rejected by scaling check (ville) Signed-off-by: Mahesh Kumar Link: http://patchwork.freedesktop.org/patch/msgid/20170630121100.20159-2-mahesh1.kumar@intel.com Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=90238 Reviewed-by: Ville Syrjälä Signed-off-by: Ville Syrjälä --- drivers/gpu/drm/i915/intel_atomic_plane.c | 15 +++++++++++++++ 1 file changed, 15 insertions(+) diff --git a/drivers/gpu/drm/i915/intel_atomic_plane.c b/drivers/gpu/drm/i915/intel_atomic_plane.c index 4325cb0..ee76fab 100644 --- a/drivers/gpu/drm/i915/intel_atomic_plane.c +++ b/drivers/gpu/drm/i915/intel_atomic_plane.c @@ -114,6 +114,8 @@ int intel_plane_atomic_check_with_state(struct intel_crtc_state *crtc_state, struct drm_i915_private *dev_priv = to_i915(plane->dev); struct drm_plane_state *state = &intel_state->base; struct intel_plane *intel_plane = to_intel_plane(plane); + const struct drm_display_mode *adjusted_mode = + &crtc_state->base.adjusted_mode; int ret; /* @@ -173,6 +175,19 @@ int intel_plane_atomic_check_with_state(struct intel_crtc_state *crtc_state, if (ret) return ret; + /* + * Y-tiling is not supported in IF-ID Interlace mode in + * GEN9 and above. + */ + if (state->fb && INTEL_GEN(dev_priv) >= 9 && crtc_state->base.enable && + adjusted_mode->flags & DRM_MODE_FLAG_INTERLACE) { + if (state->fb->modifier == I915_FORMAT_MOD_Y_TILED || + state->fb->modifier == I915_FORMAT_MOD_Yf_TILED) { + DRM_DEBUG_KMS("Y/Yf tiling not supported in IF-ID mode\n"); + return -EINVAL; + } + } + /* FIXME pre-g4x don't work like this */ if (intel_state->base.visible) crtc_state->active_planes |= BIT(intel_plane->id); -- 2.7.4
