With compose rectangle support in the capture driver, they don't have to anymore. If the direct CSI -> IC path is enabled, the CSI output width must still be aligned to 8 pixels (IC burst length). Signed-off-by: Philipp Zabel --- Changes since v1: - Relax PRP ENC and PRP VF source pad width alignment as well - Relax CSI crop width alignment to 2 pixels if direct CSI -> IC path is not enabled --- drivers/staging/media/imx/imx-ic-prpencvf.c | 2 +- drivers/staging/media/imx/imx-media-csi.c | 21 +++++++++++++++++++-- drivers/staging/media/imx/imx-media-utils.c | 15 ++++++++++++--- 3 files changed, 32 insertions(+), 6 deletions(-) diff --git a/drivers/staging/media/imx/imx-ic-prpencvf.c b/drivers/staging/media/imx/imx-ic-prpencvf.c index fe5a77baa592..7bb754cb703e 100644 --- a/drivers/staging/media/imx/imx-ic-prpencvf.c +++ b/drivers/staging/media/imx/imx-ic-prpencvf.c @@ -48,7 +48,7 @@ #define MAX_W_SRC 1024 #define MAX_H_SRC 1024 -#define W_ALIGN_SRC 4 /* multiple of 16 pixels */ +#define W_ALIGN_SRC 1 /* multiple of 2 pixels */ #define H_ALIGN_SRC 1 /* multiple of 2 lines */ #define S_ALIGN 1 /* multiple of 2 */ diff --git a/drivers/staging/media/imx/imx-media-csi.c b/drivers/staging/media/imx/imx-media-csi.c index c4523afe7b48..1b4962b8b192 100644 --- a/drivers/staging/media/imx/imx-media-csi.c +++ b/drivers/staging/media/imx/imx-media-csi.c @@ -41,7 +41,7 @@ #define MIN_H 144 #define MAX_W 4096 #define MAX_H 4096 -#define W_ALIGN 4 /* multiple of 16 pixels */ +#define W_ALIGN 1 /* multiple of 2 pixels */ #define H_ALIGN 1 /* multiple of 2 lines */ #define S_ALIGN 1 /* multiple of 2 */ @@ -1130,6 +1130,20 @@ __csi_get_compose(struct csi_priv *priv, struct v4l2_subdev_pad_config *cfg, return &priv->compose; } +static bool csi_src_pad_enabled(struct media_pad *pad) +{ + struct media_link *link; + + list_for_each_entry(link, &pad->entity->links, list) { + if (link->source->entity == pad->entity && + link->source->index == pad->index && + link->flags & MEDIA_LNK_FL_ENABLED) + return true; + } + + return false; +} + static void csi_try_crop(struct csi_priv *priv, struct v4l2_rect *crop, struct v4l2_subdev_pad_config *cfg, @@ -1141,7 +1155,10 @@ static void csi_try_crop(struct csi_priv *priv, crop->left = infmt->width - crop->width; /* adjust crop left/width to h/w alignment restrictions */ crop->left &= ~0x3; - crop->width &= ~0x7; + if (csi_src_pad_enabled(&priv->pad[CSI_SRC_PAD_DIRECT])) + crop->width &= ~0x7; /* multiple of 8 pixels (IC burst) */ + else + crop->width &= ~0x1; /* multiple of 2 pixels */ /* * FIXME: not sure why yet, but on interlaced bt.656, diff --git a/drivers/staging/media/imx/imx-media-utils.c b/drivers/staging/media/imx/imx-media-utils.c index 0eaa353d5cb3..5f110d90a4ef 100644 --- a/drivers/staging/media/imx/imx-media-utils.c +++ b/drivers/staging/media/imx/imx-media-utils.c @@ -580,6 +580,7 @@ int imx_media_mbus_fmt_to_pix_fmt(struct v4l2_pix_format *pix, struct v4l2_mbus_framefmt *mbus, const struct imx_media_pixfmt *cc) { + u32 width; u32 stride; if (!cc) { @@ -602,9 +603,16 @@ int imx_media_mbus_fmt_to_pix_fmt(struct v4l2_pix_format *pix, cc = imx_media_find_mbus_format(code, CS_SEL_YUV, false); } - stride = cc->planar ? mbus->width : (mbus->width * cc->bpp) >> 3; + /* Round up width for minimum burst size */ + width = round_up(mbus->width, 8); - pix->width = mbus->width; + /* Round up stride for IDMAC line start address alignment */ + if (cc->planar) + stride = round_up(width, 16); + else + stride = round_up((width * cc->bpp) >> 3, 8); + + pix->width = width; pix->height = mbus->height; pix->pixelformat = cc->fourcc; pix->colorspace = mbus->colorspace; @@ -613,7 +621,8 @@ int imx_media_mbus_fmt_to_pix_fmt(struct v4l2_pix_format *pix, pix->quantization = mbus->quantization; pix->field = mbus->field; pix->bytesperline = stride; - pix->sizeimage = (pix->width * pix->height * cc->bpp) >> 3; + pix->sizeimage = cc->planar ?
