From: Ville Syrjälä Date: Tue, 12 Jan 2016 19:08:34 +0000 (+0200) Subject: drm/i915: change intel_fill_fb_ggtt_view() to use the real tile size X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d9b3288ecf2f;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git drm/i915: change intel_fill_fb_ggtt_view() to use the real tile size Use the actual tile size as to compute stuff in intel_fill_fb_ggtt_view() instead of assuming it's PAGE_SIZE. I suppose it doesn't matter since we don't use the results on gen2 platforms where the tile size is 2k. v2: Update due to CbCr plane Signed-off-by: Ville Syrjälä Reviewed-by: Daniel Vetter Link: http://patchwork.freedesktop.org/patch/msgid/1452625717-9713-5-git-send-email-ville.syrjala@linux.intel.com --- diff --git a/drivers/gpu/drm/i915/intel_display.c b/drivers/gpu/drm/i915/intel_display.c index 9c20c2ee742f..79900341f944 100644 --- a/drivers/gpu/drm/i915/intel_display.c +++ b/drivers/gpu/drm/i915/intel_display.c @@ -2291,8 +2291,7 @@ intel_fill_fb_ggtt_view(struct i915_ggtt_view *view, struct drm_framebuffer *fb, { struct drm_i915_private *dev_priv = to_i915(fb->dev); struct intel_rotation_info *info = &view->params.rotation_info; - unsigned int tile_height, tile_pitch; - unsigned int cpp = drm_format_plane_cpp(fb->pixel_format, 0); + unsigned int tile_size, tile_width, tile_height, cpp; *view = i915_ggtt_view_normal; @@ -2310,19 +2309,24 @@ intel_fill_fb_ggtt_view(struct i915_ggtt_view *view, struct drm_framebuffer *fb, info->uv_offset = fb->offsets[1]; info->fb_modifier = fb->modifier[0]; - tile_height = intel_tile_height(dev_priv, fb->modifier[0], cpp); - tile_pitch = PAGE_SIZE / tile_height; - info->width_pages = DIV_ROUND_UP(fb->pitches[0], tile_pitch); + tile_size = intel_tile_size(dev_priv); + + cpp = drm_format_plane_cpp(fb->pixel_format, 0); + tile_width = intel_tile_width(dev_priv, cpp, fb->modifier[0]); + tile_height = tile_size / tile_width; + + info->width_pages = DIV_ROUND_UP(fb->pitches[0], tile_width); info->height_pages = DIV_ROUND_UP(fb->height, tile_height); - info->size = info->width_pages * info->height_pages * PAGE_SIZE; + info->size = info->width_pages * info->height_pages * tile_size; if (info->pixel_format == DRM_FORMAT_NV12) { cpp = drm_format_plane_cpp(fb->pixel_format, 1); - tile_height = intel_tile_height(dev_priv, fb->modifier[1], cpp); - tile_pitch = PAGE_SIZE / tile_height; - info->width_pages_uv = DIV_ROUND_UP(fb->pitches[1], tile_pitch); + tile_width = intel_tile_width(dev_priv, fb->modifier[1], cpp); + tile_height = tile_size / tile_width; + + info->width_pages_uv = DIV_ROUND_UP(fb->pitches[1], tile_width); info->height_pages_uv = DIV_ROUND_UP(fb->height / 2, tile_height); - info->size_uv = info->width_pages_uv * info->height_pages_uv * PAGE_SIZE; + info->size_uv = info->width_pages_uv * info->height_pages_uv * tile_size; } }
