Signed-off-by: Mark Yao --- Changes in v3: Adviced by Tomasz Figa - separate dest calculate to another patch - fix src x1,x2 when do align, and remove unnecessary src.y1 align. Changes in v2: - Uv buffer not support odd offset, align it. - Fix error display when move yuv image. drivers/gpu/drm/rockchip/rockchip_drm_vop.c | 56 ++++++++++++++++++++++++++- 1 file changed, 54 insertions(+), 2 deletions(-) diff --git a/drivers/gpu/drm/rockchip/rockchip_drm_vop.c b/drivers/gpu/drm/rockchip/rockchip_drm_vop.c index c7e0283..47ce943 100644 --- a/drivers/gpu/drm/rockchip/rockchip_drm_vop.c +++ b/drivers/gpu/drm/rockchip/rockchip_drm_vop.c @@ -373,6 +373,18 @@ static enum vop_data_format vop_convert_format(uint32_t format) } } +static bool is_yuv_support(uint32_t format) +{ + switch (format) { + case DRM_FORMAT_NV12: + case DRM_FORMAT_NV16: + case DRM_FORMAT_NV24: + return true; + default: + return false; + } +} + static bool is_alpha_support(uint32_t format) { switch (format) { @@ -577,16 +589,21 @@ static int vop_update_plane_event(struct drm_plane *plane, struct vop *vop = to_vop(crtc); struct drm_gem_object *obj; struct rockchip_gem_object *rk_obj; + struct drm_gem_object *uv_obj; + struct rockchip_gem_object *rk_uv_obj; unsigned long offset; unsigned int actual_w; unsigned int actual_h; unsigned int dsp_stx; unsigned int dsp_sty; unsigned int y_vir_stride; + unsigned int uv_vir_stride = 0; dma_addr_t yrgb_mst; + dma_addr_t uv_mst = 0; enum vop_data_format format; uint32_t val; bool is_alpha; + bool is_yuv; bool visible; int ret; struct drm_rect dest = { @@ -620,6 +637,8 @@ static int vop_update_plane_event(struct drm_plane *plane, return 0; is_alpha = is_alpha_support(fb->pixel_format); + is_yuv = is_yuv_support(fb->pixel_format); + format = vop_convert_format(fb->pixel_format); if (format < 0) return format; @@ -632,18 +651,47 @@ static int vop_update_plane_event(struct drm_plane *plane, rk_obj = to_rockchip_obj(obj); + if (is_yuv) { + /* + * Src.x1 can be odd when do clip, but yuv plane start point + * need align with 2 pixel. + */ + val = (src.x1 >> 16) % 2; + src.x1 += val << 16; + src.x2 += val << 16; + } + actual_w = (src.x2 - src.x1) >> 16; actual_h = (src.y2 - src.y1) >> 16; dsp_stx = dest.x1 + crtc->mode.htotal - crtc->mode.hsync_start; dsp_sty = dest.y1 + crtc->mode.vtotal - crtc->mode.vsync_start; - offset = (src.x1 >> 16) * (fb->bits_per_pixel >> 3); + offset = (src.x1 >> 16) * drm_format_plane_cpp(fb->pixel_format, 0); offset += (src.y1 >> 16) * fb->pitches[0]; - yrgb_mst = rk_obj->dma_addr + offset; + yrgb_mst = rk_obj->dma_addr + offset + fb->offsets[0]; y_vir_stride = fb->pitches[0] >> 2; + if (is_yuv) { + int hsub = drm_format_horz_chroma_subsampling(fb->pixel_format); + int vsub = drm_format_vert_chroma_subsampling(fb->pixel_format); + int bpp = drm_format_plane_cpp(fb->pixel_format, 1); + + uv_obj = rockchip_fb_get_gem_obj(fb, 1); + if (!uv_obj) { + DRM_ERROR("fail to get uv object from framebuffer\n"); + return -EINVAL; + } + rk_uv_obj = to_rockchip_obj(uv_obj); + uv_vir_stride = fb->pitches[1] >> 2; + + offset = (src.x1 >> 16) * bpp / hsub; + offset += (src.y1 >> 16) * fb->pitches[1] / vsub; + + uv_mst = rk_uv_obj->dma_addr + offset + fb->offsets[1]; + } + /* * If this plane update changes the plane's framebuffer, (or more * precisely, if this update has a different framebuffer than the last @@ -679,6 +727,10 @@ static int vop_update_plane_event(struct drm_plane *plane, VOP_WIN_SET(vop, win, format, format); VOP_WIN_SET(vop, win, yrgb_vir, y_vir_stride); VOP_WIN_SET(vop, win, yrgb_mst, yrgb_mst); + if (is_yuv) { + VOP_WIN_SET(vop, win, uv_vir, uv_vir_stride); + VOP_WIN_SET(vop, win, uv_mst, uv_mst); + } val = (actual_h - 1) << 16; val |= (actual_w - 1) & 0xffff; VOP_WIN_SET(vop, win, act_info, val);
