Enable this by changing the -min_buffers_needed in the vb2_queue; it will be useful for enabling -still captures without allocating more memory than absolutely necessary. - -Signed-off-by: David Plowman <david.plowman@raspberrypi.com> ---- - drivers/media/platform/bcm2835/bcm2835-unicam.c | 2 +- - 1 file changed, 1 insertion(+), 1 deletion(-) - ---- a/drivers/media/platform/bcm2835/bcm2835-unicam.c -+++ b/drivers/media/platform/bcm2835/bcm2835-unicam.c -@@ -2404,7 +2404,7 @@ static int register_node(struct unicam_d - q->buf_struct_size = sizeof(struct unicam_buffer); - q->timestamp_flags = V4L2_BUF_FLAG_TIMESTAMP_MONOTONIC; - q->lock = &node->lock; -- q->min_buffers_needed = 2; -+ q->min_buffers_needed = 1; - q->dev = &unicam->pdev->dev; - - ret = vb2_queue_init(q); |
