media: raspberrypi: cfe: Fix min_reqbufs_allocation

2025-08-20T16:36:20Z

[ Upstream commit 57b5a302b5d529db96ddc52fbccec005092ebb3d ] The driver checks if "vq->max_num_buffers + *nbuffers < 3", but vq->max_num_buffers is (by default) 32, so the check is never true. Nor does the check make sense. The original code in the BSP kernel was "vq->num_buffers + *nbuffers < 3", but got mangled along the way to upstream. The intention was to make sure that at least 3 buffers are allocated. Fix this by removing the bad lines and setting q->min_reqbufs_allocation to three.

media: platform: rpi1-cfe: drop vb2_ops_wait_prepare/finish

2025-02-18T07:11:37Z

Since commit 88785982a19d ("media: vb2: use lock if wait_prepare/finish are NULL") it is no longer needed to set the wait_prepare/finish vb2_ops callbacks as long as the lock field in vb2_queue is set. Since the vb2_ops_wait_prepare/finish callbacks already rely on that field, we can safely drop these callbacks. This simplifies the code and this is a step towards the goal of deleting these callbacks. Signed-off-by: Hans Verkuil Reviewed-by: Laurent Pinchart Signed-off-by: Mauro Carvalho Chehab

media: v4l: Convert the users of v4l2_get_link_freq to call it on a pad

2025-02-15T14:22:58Z

Call v4l2_get_link_freq() on a pad, instead of a control handler. This way we can soon convert v4l2_get_link_freq() to be callable only on a pad and remove the compatibility code.

media: raspberrypi: cfe: Fix mapping of dmabuf buffers

2024-11-07T08:05:58Z

When using buffers from DRM, DMA-API gives a warning about: "mapping sg segment longer than device claims to support [len=307200] [max=65536]" Add a call to vb2_dma_contig_set_max_seg_size() to tell the DMA-API about the supported segment size (which is UINT_MAX).

media: Switch back to struct platform_driver::remove()

2024-10-12T14:28:25Z

After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/media to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer.
