That sends the pixel buffer -and then an empty buffer with the EOS flag set. The EOS buffer -wasn't handled and returned an error up the stack. - -Handle the condition correctly by returning it to the component -if streaming, or returning with an error if stopping streaming. - -Fixes: 9384167 "staging: bcm2835-camera: Remove V4L2/MMAL buffer remapping" - -Signed-off-by: Dave Stevenson ---- - .../bcm2835-camera/bcm2835-camera.c | 21 +++++++++++-------- - .../vc04_services/bcm2835-camera/mmal-vchiq.c | 5 +++-- - 2 files changed, 15 insertions(+), 11 deletions(-) - ---- a/drivers/staging/vc04_services/bcm2835-camera/bcm2835-camera.c -+++ b/drivers/staging/vc04_services/bcm2835-camera/bcm2835-camera.c -@@ -339,16 +339,13 @@ static void buffer_cb(struct vchiq_mmal_ - - if (length == 0) { - /* stream ended */ -- if (buf) { -- /* this should only ever happen if the port is -- * disabled and there are buffers still queued -+ if (dev->capture.frame_count) { -+ /* empty buffer whilst capturing - expected to be an -+ * EOS, so grab another frame - */ -- vb2_buffer_done(&buf->vb.vb2_buf, VB2_BUF_STATE_ERROR); -- pr_debug("Empty buffer"); -- } else if (dev->capture.frame_count) { -- /* grab another frame */ - if (is_capturing(dev)) { -- pr_debug("Grab another frame"); -+ v4l2_dbg(1, bcm2835_v4l2_debug, &dev->v4l2_dev, -+ "Grab another frame"); - vchiq_mmal_port_parameter_set( - instance, - dev->capture.camera_port, -@@ -356,8 +353,14 @@ static void buffer_cb(struct vchiq_mmal_ - &dev->capture.frame_count, - sizeof(dev->capture.frame_count)); - } -+ if (vchiq_mmal_submit_buffer(instance, port, buf)) -+ v4l2_dbg(1, bcm2835_v4l2_debug, &dev->v4l2_dev, -+ "Failed to return EOS buffer"); - } else { -- /* signal frame completion */ -+ /* stopping streaming. -+ * return buffer, and signal frame completion -+ */ -+ vb2_buffer_done(&buf->vb.vb2_buf, VB2_BUF_STATE_ERROR); - complete(&dev->capture.frame_cmplt); - } - return; ---- a/drivers/staging/vc04_services/bcm2835-camera/mmal-vchiq.c -+++ b/drivers/staging/vc04_services/bcm2835-camera/mmal-vchiq.c -@@ -332,8 +332,6 @@ static int bulk_receive(struct vchiq_mma - - /* store length */ - msg_context->u.bulk.buffer_used = rd_len; -- msg_context->u.bulk.mmal_flags = -- msg->u.buffer_from_host.buffer_header.flags; - msg_context->u.bulk.dts = msg->u.buffer_from_host.buffer_header.dts; - msg_context->u.bulk.pts = msg->u.buffer_from_host.buffer_header.pts; - -@@ -461,6 +459,9 @@ static void buffer_to_host_cb(struct vch - return; - } - -+ msg_context->u.bulk.mmal_flags = -+ msg->u.buffer_from_host.buffer_header.flags; -+ - if (msg->h.status != MMAL_MSG_STATUS_SUCCESS) { - /* message reception had an error */ - pr_warn("error %d in reply\n", msg->h.status);
