From ef78ec9423b9ee9f8f3dfe92dffb900cb83365ec Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Tue, 13 Oct 2015 22:48:39 +0300 Subject: [PATCH] drm/i915: Don't pass pitch to intel_compute_page_offset() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit intel_compute_page_offset() can dig up the correct pitch from the fb itself, no need for the caller to pass it in. A bit of extra care is needed for the lower level _intel_compute_page_offset() since that one gets called before the rotated pitch under intel_fb is populated. Note that we don't actually call it with anything but DRM_ROTATE_0 there so we wouldn't actually look up the rotated pitch there, but still, leave the pitch as something the caller has to pass to _intel_compute_page_offset() as an indicator that something is a bit special. This leaves 'stride_div' in the skl plane update hooks as a mostly useless variable so just get rid of it. v2: Add a note why stride_div got nuked v3: Extract intel_fb_pitch() since it can be useful later Signed-off-by: Ville Syrjälä Reviewed-by: Daniel Vetter (v2) Reviewed-by: Sivakumar Thulasimani Link: http://patchwork.freedesktop.org/patch/msgid/1470821001-25272-3-git-send-email-ville.syrjala@linux.intel.com --- drivers/gpu/drm/i915/intel_display.c | 34 ++++++++++++++++------------ drivers/gpu/drm/i915/intel_drv.h | 1 - drivers/gpu/drm/i915/intel_sprite.c | 26 +++++++++------------ 3 files changed, 31 insertions(+), 30 deletions(-) diff --git a/drivers/gpu/drm/i915/intel_display.c b/drivers/gpu/drm/i915/intel_display.c index 7c61ab4e5c64..05e6ec3e0029 100644 --- a/drivers/gpu/drm/i915/intel_display.c +++ b/drivers/gpu/drm/i915/intel_display.c @@ -2267,6 +2267,15 @@ void intel_unpin_fb_obj(struct drm_framebuffer *fb, unsigned int rotation) i915_gem_object_unpin_from_display_plane(obj, &view);
