From 102af9b9922f658f705a4b0deaccabac409131bf Mon Sep 17 00:00:00 2001 From: Benoit Parrot Date: Mon, 7 Oct 2019 12:09:50 -0300 Subject: media: ti-vpe: vpe: Fix Motion Vector vpdma stride commit 3dc2046ca78b ("[media] media: ti-vpe: vpe: allow use of user specified stride") and commit da4414eaed15 ("[media] media: ti-vpe: vpdma: add support for user specified stride") resulted in the Motion Vector stride to be the same as the image stride. This caused memory corruption in the output image as mentioned in commit 00db969964c8 ("[media] media: ti-vpe: vpe: Fix line stride for output motion vector"). Fixes: 3dc2046ca78b ("[media] media: ti-vpe: vpe: allow use of user specified stride") Fixes: da4414eaed15 ("[media] media: ti-vpe: vpdma: add support for user specified stride") Signed-off-by: Benoit Parrot Acked-by: Nikhil Devshatwar Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab --- drivers/media/platform/ti-vpe/vpe.c | 18 +++++++++++++----- 1 file changed, 13 insertions(+), 5 deletions(-) (limited to 'drivers/media/platform/ti-vpe') diff --git a/drivers/media/platform/ti-vpe/vpe.c b/drivers/media/platform/ti-vpe/vpe.c index 60b575bb44c4..5ba72445584d 100644 --- a/drivers/media/platform/ti-vpe/vpe.c +++ b/drivers/media/platform/ti-vpe/vpe.c @@ -1013,11 +1013,14 @@ static void add_out_dtd(struct vpe_ctx *ctx, int port) dma_addr_t dma_addr; u32 flags = 0; u32 offset = 0; + u32 stride; if (port == VPE_PORT_MV_OUT) { vpdma_fmt = &vpdma_misc_fmts[VPDMA_DATA_FMT_MV]; dma_addr = ctx->mv_buf_dma[mv_buf_selector]; q_data = &ctx->q_data[Q_DATA_SRC]; + stride = ALIGN((q_data->width * vpdma_fmt->depth) >> 3, + VPDMA_STRIDE_ALIGN); } else { /* to incorporate interleaved formats */ int plane = fmt->coplanar ? p_data->vb_part : 0; @@ -1044,6 +1047,7 @@ static void add_out_dtd(struct vpe_ctx *ctx, int port) } /* Apply the offset */ dma_addr += offset; + stride = q_data->bytesperline[VPE_LUMA]; } if (q_data->flags & Q_DATA_FRAME_1D) @@ -1055,7 +1059,7 @@ static void add_out_dtd(struct vpe_ctx *ctx, int port) MAX_W, MAX_H); vpdma_add_out_dtd(&ctx->desc_list, q_data->width, - q_data->bytesperline[VPE_LUMA], &q_data->c_rect, + stride, &q_data->c_rect, vpdma_fmt, dma_addr, MAX_OUT_WIDTH_REG1, MAX_OUT_HEIGHT_REG1, p_data->channel, flags); } @@ -1074,10 +1078,13 @@ static void add_in_dtd(struct vpe_ctx *ctx, int port) dma_addr_t dma_addr; u32 flags = 0; u32 offset = 0; + u32 stride; if (port == VPE_PORT_MV_IN) { vpdma_fmt = &vpdma_misc_fmts[VPDMA_DATA_FMT_MV]; dma_addr = ctx->mv_buf_dma[mv_buf_selector]; + stride = ALIGN((q_data->width * vpdma_fmt->depth) >> 3, + VPDMA_STRIDE_ALIGN); } else { /* to incorporate interleaved formats */ int plane = fmt->coplanar ? p_data->vb_part : 0; @@ -1104,6 +1111,7 @@ static void add_in_dtd(struct vpe_ctx *ctx, int port) } /* Apply the offset */ dma_addr += offset; + stride = q_data->bytesperline[VPE_LUMA]; if (q_data->flags & Q_DATA_INTERLACED_SEQ_TB) { /* @@ -1139,10 +1147,10 @@ static void add_in_dtd(struct vpe_ctx *ctx, int port) if (p_data->vb_part && fmt->fourcc == V4L2_PIX_FMT_NV12) frame_height /= 2; - vpdma_add_in_dtd(&ctx->desc_list, q_data->width, - q_data->bytesperline[VPE_LUMA], &q_data->c_rect, - vpdma_fmt, dma_addr, p_data->channel, field, flags, frame_width, - frame_height, 0, 0); + vpdma_add_in_dtd(&ctx->desc_list, q_data->width, stride, + &q_data->c_rect, vpdma_fmt, dma_addr, + p_data->channel, field, flags, frame_width, + frame_height, 0, 0); } /* -- cgit
