From 93ca7e00667063a8dc86f04373e85e89a09efef4 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Mon, 26 Sep 2016 19:30:56 +0300 Subject: [PATCH] drm/i915: Use the per-plane rotation property MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit On certain platforms not all planes support the same set of rotations/reflections, so let's use the per-plane property for this. This is already a problem on SKL when we use the legay cursor plane as it only supports 0|180 whereas the universal planes support 0|90|180|270, and it will be a problem on CHV soon. v2: Use drm_plane_create_rotation_property() helper v3: Drop the BIT(), use INTEL_GEN() Signed-off-by: Ville Syrjälä Reviewed-by: Chris Wilson (v1) Reviewed-by: Joonas Lahtinen Signed-off-by: Daniel Vetter Link: http://patchwork.freedesktop.org/patch/msgid/1474907460-10717-12-git-send-email-ville.syrjala@linux.intel.com --- drivers/gpu/drm/i915/intel_display.c | 52 +++++++++++++++--------------------- drivers/gpu/drm/i915/intel_drv.h | 3 --- drivers/gpu/drm/i915/intel_sprite.c | 14 +++++++++- 3 files changed, 34 insertions(+), 35 deletions(-) diff --git a/drivers/gpu/drm/i915/intel_display.c b/drivers/gpu/drm/i915/intel_display.c index af18e2c..6c5c36e 100644 --- a/drivers/gpu/drm/i915/intel_display.c +++ b/drivers/gpu/drm/i915/intel_display.c @@ -14886,6 +14886,7 @@ static struct drm_plane *intel_primary_plane_create(struct drm_device *dev, struct intel_plane *primary = NULL;
