If the saa7134 module is loaded with the saa7134_userptr set to 1, then USERPTR support is enabled. A check in buffer_prepare verifies that the pointer is page-aligned. Signed-off-by:

Convert the saa7134 driver to vb2. Note that while this uses the vb2-dma-sg version, the VB2_USERPTR mode is disabled. The DMA hardware only supports DMAing full pages, and in the USERPTR memory model the first and last scatter-gather buffer is almost never a full page. In practice this means that we can't use the VB2_USERPTR mode. This has been tested with raw video, compressed video, VBI, radio, DVB and video overlays. Unfortunately, a vb2 conversion is one of those things you cannot split up in smaller patches, it's all or nothing. This patch switches the whole driver over to vb2, using the vb2 ioctl and fop helper functions. Signed-off-by:

num_buffers can't be bigger than VIDEO_MAX_FRAME. This is assured by: num_buffers = min_t(unsigned int, req->count, VIDEO_MAX_FRAME); However, this value is overriden by: num_buffers = max_t(unsigned int, req->count, q->min_buffers_needed); It should, instead, use the previously calculated value as an input to max_t: num_buffers = max_t(unsigned int, num_buffers, q->min_buffers_needed); Signed-off-by:

The __vb2_queue_cancel function marks the queue as not streaming and then WARNs when buffers are still owned by the driver. It proceeds to complete all active buffers by calling vb2_buffer_done with the new buffer state set to VB2_BUF_STATE_ERROR in that case. This triggers another WARN_ON due to as new state not being VB2_BUF_STATE_QUEUED while the queue is not streaming. Check buffer ownership and complete all active buffers before marking the queue as not streaming to avoid the double WARN_on. Signed-off-by:

vb2_get_vma() copy the content of the vma to a new structure but set some of its pointers to NULL. One of this pointer is used by follow_pte() called by follow_pfn() on io memory. This can lead to a NULL pointer derreference. The version of vma that has not been cleared must be used.
