From 1663b9d6a26a4d118e497b0a1604948b0fb0c86e Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Mon, 15 Feb 2016 22:54:45 +0200 Subject: [PATCH] drm/i915: Reorganize intel_rotation_info MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Throw out a bunch of unnecessary stuff from struct intel_rotation_info, and pull most of the remaining stuff to live under an array of per-color plane sub-structures. What still remains outside the sub-structure will be reorgranized later as well, but that requires more work elsewhere so leave it be for now. v2: Split the vma size == luma+chroma size fix to prep patch (Daniel) Signed-off-by: Ville Syrjälä Reviewed-by: Daniel Vetter (v1) Link: http://patchwork.freedesktop.org/patch/msgid/1455569699-27905-8-git-send-email-ville.syrjala@linux.intel.com --- drivers/gpu/drm/i915/i915_gem_gtt.c | 35 +++++++++++++++-------------------- drivers/gpu/drm/i915/i915_gem_gtt.h | 11 ++++------- drivers/gpu/drm/i915/intel_display.c | 25 +++++++++++++++---------- drivers/gpu/drm/i915/intel_drv.h | 1 + 4 files changed, 35 insertions(+), 37 deletions(-) diff --git a/drivers/gpu/drm/i915/i915_gem_gtt.c b/drivers/gpu/drm/i915/i915_gem_gtt.c index a1930f9..a794bbd 100644 --- a/drivers/gpu/drm/i915/i915_gem_gtt.c +++ b/drivers/gpu/drm/i915/i915_gem_gtt.c @@ -3405,7 +3405,7 @@ static struct sg_table * intel_rotate_fb_obj_pages(struct intel_rotation_info *rot_info, struct drm_i915_gem_object *obj) { - unsigned int size_pages = rot_info->size >> PAGE_SHIFT; + unsigned int size_pages = rot_info->plane[0].width * rot_info->plane[0].height; unsigned int size_pages_uv; struct sg_page_iter sg_iter; unsigned long i; @@ -3423,7 +3423,7 @@ intel_rotate_fb_obj_pages(struct intel_rotation_info *rot_info, /* Account for UV plane with NV12. */ if (rot_info->pixel_format == DRM_FORMAT_NV12) - size_pages_uv = rot_info->size_uv >> PAGE_SHIFT; + size_pages_uv = rot_info->plane[1].width * rot_info->plane[1].height; else size_pages_uv = 0; @@ -3445,9 +3445,9 @@ intel_rotate_fb_obj_pages(struct intel_rotation_info *rot_info, /* Rotate the pages. */ sg = rotate_pages(page_addr_list, 0, - rot_info->width_pages, rot_info->height_pages, - rot_info->width_pages, - st, NULL); + rot_info->plane[0].width, rot_info->plane[0].height, + rot_info->plane[0].width, + st, NULL); /* Append the UV plane if NV12. */ if (rot_info->pixel_format == DRM_FORMAT_NV12) { @@ -3459,18 +3459,15 @@ intel_rotate_fb_obj_pages(struct intel_rotation_info *rot_info, rot_info->uv_start_page = uv_start_page; - rotate_pages(page_addr_list, uv_start_page, - rot_info->width_pages_uv, - rot_info->height_pages_uv, - rot_info->width_pages_uv, + rotate_pages(page_addr_list, rot_info->uv_start_page, + rot_info->plane[1].width, rot_info->plane[1].height, + rot_info->plane[1].width, st, sg); } - DRM_DEBUG_KMS( - "Created rotated page mapping for object size %zu (pitch=%u, height=%u, pixel_format=0x%x, %ux%u tiles, %u pages (%u plane 0)).\n", - obj->base.size, rot_info->pitch, rot_info->height, - rot_info->pixel_format, rot_info->width_pages, - rot_info->height_pages, size_pages + size_pages_uv, + DRM_DEBUG_KMS("Created rotated page mapping for object size %zu (%ux%u tiles, %u pages (%u plane 0)).\n", + obj->base.size, rot_info->plane[0].width, + rot_info->plane[0].height, size_pages + size_pages_uv, size_pages); drm_free_large(page_addr_list); @@ -3482,11 +3479,9 @@ err_sg_alloc: err_st_alloc: drm_free_large(page_addr_list); - DRM_DEBUG_KMS( - "Failed to create rotated mapping for object size %zu!
