From df0cd455e720e4c0a04a85eb8ec4d2dab2e37795 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Mon, 14 Nov 2016 18:53:59 +0200 Subject: [PATCH] drm/i915: Clean up rotation DSPCNTR/DVSCNTR/etc. setup MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Move the plane control register rotation setup away from the coordinate munging code. This will result in neater looking code once we add reflection support for CHV. v2: Drop the BIT(), drop some usless parens, Signed-off-by: Ville Syrjälä Reviewed-by: Chris Wilson Reviewed-by: Joonas Lahtinen Link: http://patchwork.freedesktop.org/patch/msgid/1479142440-25283-3-git-send-email-ville.syrjala@linux.intel.com --- drivers/gpu/drm/i915/intel_display.c | 24 +++++++++++++----------- drivers/gpu/drm/i915/intel_sprite.c | 26 ++++++++++++++------------ 2 files changed, 27 insertions(+), 23 deletions(-) diff --git a/drivers/gpu/drm/i915/intel_display.c b/drivers/gpu/drm/i915/intel_display.c index 10dd1ef57c30..ecc7b5b444f6 100644 --- a/drivers/gpu/drm/i915/intel_display.c +++ b/drivers/gpu/drm/i915/intel_display.c @@ -3075,6 +3075,9 @@ static void i9xx_update_primary_plane(struct drm_plane *primary, fb->modifier[0] == I915_FORMAT_MOD_X_TILED) dspcntr |= DISPPLANE_TILED; + if (rotation & DRM_ROTATE_180) + dspcntr |= DISPPLANE_ROTATE_180; + if (IS_G4X(dev_priv)) dspcntr |= DISPPLANE_TRICKLE_FEED_DISABLE; @@ -3085,10 +3088,8 @@ static void i9xx_update_primary_plane(struct drm_plane *primary, intel_compute_tile_offset(&x, &y, plane_state, 0); if (rotation & DRM_ROTATE_180) { - dspcntr |= DISPPLANE_ROTATE_180; - - x += (crtc_state->pipe_src_w - 1); - y += (crtc_state->pipe_src_h - 1); + x += crtc_state->pipe_src_w - 1; + y += crtc_state->pipe_src_h - 1; } linear_offset = intel_fb_xy_to_linear(x, y, plane_state, 0); @@ -3180,6 +3181,9 @@ static void ironlake_update_primary_plane(struct drm_plane *primary, if (fb->modifier[0] == I915_FORMAT_MOD_X_TILED) dspcntr |= DISPPLANE_TILED; + if (rotation & DRM_ROTATE_180) + dspcntr |= DISPPLANE_ROTATE_180; + if (!IS_HASWELL(dev_priv) && !IS_BROADWELL(dev_priv)) dspcntr |= DISPPLANE_TRICKLE_FEED_DISABLE; @@ -3188,13 +3192,11 @@ static void ironlake_update_primary_plane(struct drm_plane *primary, intel_crtc->dspaddr_offset = intel_compute_tile_offset(&x, &y, plane_state, 0); - if (rotation & DRM_ROTATE_180) { - dspcntr |= DISPPLANE_ROTATE_180; - - if (!IS_HASWELL(dev_priv) && !IS_BROADWELL(dev_priv)) { - x += (crtc_state->pipe_src_w - 1); - y += (crtc_state->pipe_src_h - 1); - } + /* HSW+ does this automagically in hardware */ + if (!IS_HASWELL(dev_priv) && !IS_BROADWELL(dev_priv) && + rotation & DRM_ROTATE_180) { + x += crtc_state->pipe_src_w - 1; + y += crtc_state->pipe_src_h - 1; } linear_offset = intel_fb_xy_to_linear(x, y, plane_state, 0); diff --git a/drivers/gpu/drm/i915/intel_sprite.c b/drivers/gpu/drm/i915/intel_sprite.c index ea85d27af217..7951b70bf792 100644 --- a/drivers/gpu/drm/i915/intel_sprite.c +++ b/drivers/gpu/drm/i915/intel_sprite.c @@ -427,6 +427,9 @@ vlv_update_plane(struct drm_plane *dplane, if (fb->modifier[0] == I915_FORMAT_MOD_X_TILED) sprctl |= SP_TILED; + if (rotation & DRM_ROTATE_180) + sprctl |= SP_ROTATE_180; + /* Sizes are 0 based */ src_w--; src_h--; @@ -437,8 +440,6 @@ vlv_update_plane(struct drm_plane *dplane, sprsurf_offset = intel_compute_tile_offset(&x, &y, plane_state, 0); if (rotation & DRM_ROTATE_180) { - sprctl |= SP_ROTATE_180; - x += src_w; y += src_h; } @@ -546,6 +547,9 @@ ivb_update_plane(struct drm_plane *plane, if (fb->modifier[0] == I915_FORMAT_MOD_X_TILED) sprctl |= SPRITE_TILED; + if (rotation & DRM_ROTATE_180) + sprctl |= SPRITE_ROTATE_180; + if (IS_HASWELL(dev_priv) || IS_BROADWELL(dev_priv)) sprctl &= ~SPRITE_TRICKLE_FEED_DISABLE; else @@ -566,14 +570,11 @@ ivb_update_plane(struct drm_plane *plane, intel_add_fb_offsets(&x, &y, plane_state, 0); sprsurf_offset = intel_compute_tile_offset(&x, &y, plane_state, 0); - if (rotation & DRM_ROTATE_180) { - sprctl |= SPRITE_ROTATE_180; - - /* HSW and BDW does this automagically in hardware */ - if (!IS_HASWELL(dev_priv) && !IS_BROADWELL(dev_priv)) { - x += src_w; - y += src_h; - } + /* HSW+ does this automagically in hardware */ + if (!IS_HASWELL(dev_priv) && !IS_BROADWELL(dev_priv) && + rotation & DRM_ROTATE_180) { + x += src_w; + y += src_h; } linear_offset = intel_fb_xy_to_linear(x, y, plane_state, 0); @@ -684,6 +685,9 @@ ilk_update_plane(struct drm_plane *plane, if (fb->modifier[0] == I915_FORMAT_MOD_X_TILED) dvscntr |= DVS_TILED; + if (rotation & DRM_ROTATE_180) + dvscntr |= DVS_ROTATE_180; + if (IS_GEN6(dev_priv)) dvscntr |= DVS_TRICKLE_FEED_DISABLE; /* must disable */ @@ -701,8 +705,6 @@ ilk_update_plane(struct drm_plane *plane, dvssurf_offset = intel_compute_tile_offset(&x, &y, plane_state, 0); if (rotation & DRM_ROTATE_180) { - dvscntr |= DVS_ROTATE_180; - x += src_w; y += src_h; } -- 2.30.2
