commit 1a0c10ed ("media: dvb-usb-v2: stop using coherent memory for URBs") incorrectly adds URB_FREE_BUFFER after every urb transfer. It cannot use this flag because it reconfigures the URBs accordingly to suit connected devices. In doing a call to usb_free_urb is made and invertedly frees the buffers. The stream buffer should remain constant while driver is up. Signed-off-by:

The last buffer is often signaled by an empty buffer with the V4L2_BUF_FLAG_LAST flag set. Such buffers were returned with the bytesused field set to the full size of the OPB, which leads user-space to believe that the buffer actually contains useful data. Fix this by passing the number of bytes reported used by the firmware. Signed-off-by:

Tuners should report frequencies in Hz. That works fine on most drivers, but, in the case of dvb-pll, some settings are for satellite tuners, while others are for terrestrial/cable ones. The code was trying to solve it at probing time, but that doesn't work, as, when _attach is called, the delivery system may be wrong. Fix it by ensuring that all frequencies are in Hz at the per-tuner max/min values. While here, add a debug message, as this would help to debug any issues there.

Userspace shouldn't set bytesused to 0 for output buffers. vb2_warn_zero_bytesused() warns about this (only once!), but it also calls WARN_ON(1), which is confusing since it is not immediately clear that it warns about a 0 value for bytesused. Just drop the WARN_ON as it serves no purpose. Signed-off-by:

Videobuf2 presently does not allow VIDIOC_REQBUFS to destroy outstanding buffers if the queue is of type V4L2_MEMORY_MMAP, and if the buffers are considered "in use". This is different behavior than for other memory types and prevents us from deallocating buffers in following two cases: 1) There are outstanding mmap()ed views on the buffer. However even if we put the buffer in reqbufs(0), there will be remaining references, due to vma .open/close() adjusting vb2 buffer refcount appropriately. This means that the buffer will be in fact freed only when the last mmap()ed view is unmapped. 2) Buffer has been exported as a DMABUF. Refcount of the vb2 buffer is managed properly by VB2 DMABUF ops, i.e. incremented on DMABUF get and decremented on DMABUF release. This means that the buffer will be alive until all importers release it. Considering both cases above, there does not seem to be any need to prevent reqbufs(0) operation, because buffer lifetime is already properly managed by both mmap() and DMABUF code paths. Let's remove it and allow userspace freeing the queue (and potentially allocating a new one) even though old buffers might be still in processing. To let userspace know that the kernel now supports orphaning buffers that are still in use, add a new V4L2_BUF_CAP_SUPPORTS_ORPHANED_BUFS to be set by reqbufs and create_bufs.

Now that the mem2mem framework guarantees that .device_run won't be called from interrupt context, it is safe to call v4l2_m2m_job_finish directly in the top-half. So this means the bottom-half is no longer needed and we can get rid of it. Signed-off-by:

v4l2_m2m_job_finish() is typically called when DMA operations complete, in interrupt handlers or DMA completion callbacks. Calling .device_run from v4l2_m2m_job_finish creates a nasty re-entrancy path into the driver. Moreover, some implementation of .device_run might need to sleep, as is the case for drivers supporting the Request API, where controls are applied via v4l2_ctrl_request_setup, which takes the ctrl handler mutex. This commit adds a deferred context that calls v4l2_m2m_try_run, and gets scheduled by v4l2_m2m_job_finish(). Before this change, device_run would be called from these paths: vb2_m2m_request_queue, or v4l2_m2m_streamon, or v4l2_m2m_qbuf v4l2_m2m_try_schedule v4l2_m2m_try_run .device_run v4l2_m2m_job_finish v4l2_m2m_try_run .device_run After this change, the latter is now gone and instead: v4l2_m2m_device_run_work v4l2_m2m_try_run .device_run Signed-off-by: -

Now that the mutexes for output and capture vb2 queues match, it is possible to refer to the context q_lock as the m2m lock for a given m2m context. Remove the output/capture lock selection. Signed-off-by:
-
Ezequiel Garcia authored
Currently, all the mem2mem driver either use a single mutex to lock the capture and output videobuf2 queues, or don't set any mutex. This means the mutexes match, and so the mem2mem framework is able to set the m2m context lock. Enforce this by making it mandatory for drivers to set the same capture and output mutex, or not set any mutex at all. Signed-off-by:
