From: Gustavo Padovan <gustavo.padovan@xxxxxxxxxxxxxxx> XR24 planes were not shown properly, so now set the right registers to correctly enable displaying these planes. It also moves the alpha register settings to fimd_win_set_pixfmt() to keep all pixel format stuff together. v2: remove leftover var alpha Signed-off-by: Gustavo Padovan <gustavo.padovan@xxxxxxxxxxxxxxx> --- drivers/gpu/drm/exynos/exynos_drm_fimd.c | 33 +++++++++++++++++++++----------- include/video/samsung_fimd.h | 5 +++++ 2 files changed, 27 insertions(+), 11 deletions(-) diff --git a/drivers/gpu/drm/exynos/exynos_drm_fimd.c b/drivers/gpu/drm/exynos/exynos_drm_fimd.c index 925fc69..4c56fa7 100644 --- a/drivers/gpu/drm/exynos/exynos_drm_fimd.c +++ b/drivers/gpu/drm/exynos/exynos_drm_fimd.c @@ -54,6 +54,9 @@ /* size control register for hardware windows 1 ~ 2. */ #define VIDOSD_D(win) (VIDOSD_BASE + 0x0C + (win) * 16) +#define VIDWnALPHA0(win) (VIDW_ALPHA + 0x00 + (win) * 8) +#define VIDWnALPHA1(win) (VIDW_ALPHA + 0x04 + (win) * 8) + #define VIDWx_BUF_START(win, buf) (VIDW_BUF_START(buf) + (win) * 8) #define VIDWx_BUF_END(win, buf) (VIDW_BUF_END(buf) + (win) * 8) #define VIDWx_BUF_SIZE(win, buf) (VIDW_BUF_SIZE(buf) + (win) * 4) @@ -623,6 +626,24 @@ static void fimd_win_set_pixfmt(struct fimd_context *ctx, unsigned int win) } writel(val, ctx->regs + WINCON(win)); + + /* hardware window 0 doesn't support alpha channel. */ + if (win != 0) { + /* OSD alpha */ + val = VIDISD14C_ALPHA0_R(0xf) | + VIDISD14C_ALPHA0_G(0xf) | + VIDISD14C_ALPHA0_B(0xf) | + VIDISD14C_ALPHA1_R(0xf) | + VIDISD14C_ALPHA1_G(0xf) | + VIDISD14C_ALPHA1_B(0xf); + + writel(val, ctx->regs + VIDOSD_C(win)); + + val = VIDW_ALPHA_R(0xf) | VIDW_ALPHA_G(0xf) | + VIDW_ALPHA_G(0xf); + writel(val, ctx->regs + VIDWnALPHA0(win)); + writel(val, ctx->regs + VIDWnALPHA1(win)); + } } static void fimd_win_set_colkey(struct fimd_context *ctx, unsigned int win) @@ -670,7 +691,7 @@ static void fimd_win_commit(struct exynos_drm_crtc *crtc, int zpos) struct fimd_context *ctx = crtc->ctx; struct fimd_win_data *win_data; int win = zpos; - unsigned long val, alpha, size; + unsigned long val, size; unsigned int last_x; unsigned int last_y; @@ -747,16 +768,6 @@ static void fimd_win_commit(struct exynos_drm_crtc *crtc, int zpos) DRM_DEBUG_KMS("osd pos: tx = %d, ty = %d, bx = %d, by = %d\n", win_data->offset_x, win_data->offset_y, last_x, last_y); - /* hardware window 0 doesn't support alpha channel. */ - if (win != 0) { - /* OSD alpha */ - alpha = VIDISD14C_ALPHA1_R(0xf) | - VIDISD14C_ALPHA1_G(0xf) | - VIDISD14C_ALPHA1_B(0xf); - - writel(alpha, ctx->regs + VIDOSD_C(win)); - } - /* OSD size */ if (win != 3 && win != 4) { u32 offset = VIDOSD_D(win); diff --git a/include/video/samsung_fimd.h b/include/video/samsung_fimd.h index a20e4a3..5132428 100644 --- a/include/video/samsung_fimd.h +++ b/include/video/samsung_fimd.h @@ -289,6 +289,11 @@ #define VIDISD14C_ALPHA1_B_LIMIT 0xf #define VIDISD14C_ALPHA1_B(_x) ((_x) << 0) +#define VIDW_ALPHA 0x021c +#define VIDW_ALPHA_R(_x) ((_x) << 16) +#define VIDW_ALPHA_G(_x) ((_x) << 8) +#define VIDW_ALPHA_B(_x) ((_x) << 0) + /* Video buffer addresses */ #define VIDW_BUF_START(_buff) (0xA0 + ((_buff) * 8)) #define VIDW_BUF_START1(_buff) (0xA4 + ((_buff) * 8)) -- 2.1.0 _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
