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 Signed-off-by: Ville Syrjälä Reviewed-by: Daniel Vetter --- drivers/gpu/drm/i915/intel_display.c | 30 ++++++++++++++++-------------- drivers/gpu/drm/i915/intel_drv.h | 1 - drivers/gpu/drm/i915/intel_sprite.c | 26 +++++++++++--------------- 3 files changed, 27 insertions(+), 30 deletions(-) diff --git a/drivers/gpu/drm/i915/intel_display.c b/drivers/gpu/drm/i915/intel_display.c index ef68892f4e0a..eb8ce8a99291 100644 --- a/drivers/gpu/drm/i915/intel_display.c +++ b/drivers/gpu/drm/i915/intel_display.c @@ -2562,11 +2562,16 @@ static u32 _intel_compute_tile_offset(const struct drm_i915_private *dev_priv, unsigned int intel_compute_tile_offset(int *x, int *y, const struct drm_framebuffer *fb, int plane, - unsigned int pitch, unsigned int rotation) { const struct drm_i915_private *dev_priv = to_i915(fb->dev); unsigned int alignment = intel_surf_alignment(dev_priv, fb->modifier[plane]); + unsigned int pitch; + + if (intel_rotation_90_or_270(rotation)) + pitch = to_intel_framebuffer(fb)->rotated[plane].pitch; + else + pitch = fb->pitches[plane]; return _intel_compute_tile_offset(dev_priv, x, y, fb, plane, pitch, rotation, alignment ?
