The vicodec driver was missing support for these controls. Add them. Signed-off-by: Hans Verkuil --- Change since v2: set min_reqbufs_allocation to the same value as used for V4L2_CID_MIN_BUFFERS_FOR_OUTPUT/CAPTURE. Change since v1: V4L2_CID_MIN_BUFFERS_FOR_OUTPUT was already supported, so that patch led to duplicated controls. That's now fixed. --- .../media/test-drivers/vicodec/vicodec-core.c | 22 ++++++++++++++----- 1 file changed, 16 insertions(+), 6 deletions(-) diff --git a/drivers/media/test-drivers/vicodec/vicodec-core.c b/drivers/media/test-drivers/vicodec/vicodec-core.c index 00c84a06f343..556ec2a3d411 100644 --- a/drivers/media/test-drivers/vicodec/vicodec-core.c +++ b/drivers/media/test-drivers/vicodec/vicodec-core.c @@ -43,6 +43,8 @@ MODULE_PARM_DESC(debug, " activates debug info"); #define MIN_WIDTH 640U #define MAX_HEIGHT 2160U #define MIN_HEIGHT 360U +/* Recommended number of buffers for the stateful codecs */ +#define VICODEC_REC_BUFS 2 #define dprintk(dev, fmt, arg...) \ v4l2_dbg(1, debug, &dev->v4l2_dev, "%s: " fmt, __func__, ## arg) @@ -1705,12 +1707,14 @@ static int queue_init(void *priv, struct vb2_queue *src_vq, src_vq->ops = &vicodec_qops; src_vq->mem_ops = &vb2_vmalloc_memops; src_vq->timestamp_flags = V4L2_BUF_FLAG_TIMESTAMP_COPY; - if (ctx->is_enc) + if (ctx->is_enc) { src_vq->lock = &ctx->dev->stateful_enc.mutex; - else if (ctx->is_stateless) + src_vq->min_reqbufs_allocation = VICODEC_REC_BUFS; + } else if (ctx->is_stateless) { src_vq->lock = &ctx->dev->stateless_dec.mutex; - else + } else { src_vq->lock = &ctx->dev->stateful_dec.mutex; + } src_vq->supports_requests = ctx->is_stateless; src_vq->requires_requests = ctx->is_stateless; ret = vb2_queue_init(src_vq); @@ -1728,6 +1732,8 @@ static int queue_init(void *priv, struct vb2_queue *src_vq, dst_vq->mem_ops = &vb2_vmalloc_memops; dst_vq->timestamp_flags = V4L2_BUF_FLAG_TIMESTAMP_COPY; dst_vq->lock = src_vq->lock; + if (!ctx->is_stateless && !ctx->is_enc) + dst_vq->min_reqbufs_allocation = VICODEC_REC_BUFS; return vb2_queue_init(dst_vq); } @@ -1852,9 +1858,13 @@ static int vicodec_open(struct file *file) 1, 31, 1, 20); v4l2_ctrl_new_std(hdl, &vicodec_ctrl_ops, V4L2_CID_FWHT_P_FRAME_QP, 1, 31, 1, 20); - if (ctx->is_enc) - v4l2_ctrl_new_std(hdl, &vicodec_ctrl_ops, - V4L2_CID_MIN_BUFFERS_FOR_OUTPUT, 1, 1, 1, 1); + if (!ctx->is_stateless) + v4l2_ctrl_new_std(hdl, &vicodec_ctrl_ops, ctx->is_enc ? + V4L2_CID_MIN_BUFFERS_FOR_OUTPUT : + V4L2_CID_MIN_BUFFERS_FOR_CAPTURE, + VICODEC_REC_BUFS, VICODEC_REC_BUFS, 1, + VICODEC_REC_BUFS); + if (ctx->is_stateless) v4l2_ctrl_new_custom(hdl, &vicodec_ctrl_stateless_state, NULL); if (hdl->error) {
