From d21967740f4b7d7af794badac91b2c718b8f17c3 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Thu, 28 Jan 2016 18:33:11 +0200 Subject: [PATCH] drm/i915: Move SKL hw stride calculation into a helper MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit We repeat the SKL stride register value calculations a several places. Move it into a small helper function. v2: Rebase due to drm_plane_state src/dst rects Signed-off-by: Ville Syrjälä Reviewed-by: Matthew Auld Reviewed-by: Sivakumar Thulasimani Link: http://patchwork.freedesktop.org/patch/msgid/1470821001-25272-4-git-send-email-ville.syrjala@linux.intel.com --- drivers/gpu/drm/i915/intel_display.c | 52 +++++++++++++--------------- drivers/gpu/drm/i915/intel_drv.h | 2 ++ drivers/gpu/drm/i915/intel_sprite.c | 12 ++----- 3 files changed, 29 insertions(+), 37 deletions(-) diff --git a/drivers/gpu/drm/i915/intel_display.c b/drivers/gpu/drm/i915/intel_display.c index 05e6ec3e0029..cb82fa83aef1 100644 --- a/drivers/gpu/drm/i915/intel_display.c +++ b/drivers/gpu/drm/i915/intel_display.c @@ -3027,6 +3027,28 @@ static void skl_detach_scalers(struct intel_crtc *intel_crtc) } } +u32 skl_plane_stride(const struct drm_framebuffer *fb, int plane, + unsigned int rotation) +{ + const struct drm_i915_private *dev_priv = to_i915(fb->dev);
