The encoder driver has no need to do any CPU access to the source frame buffers. Use a separate structure for holding DMA addresses and sizes for those and remove, so we do not end up introducing any erroneous dereferences of those VAs. This fixes DMA-buf import from exporters that do not provide contiguous kernel mappings, which includes the MTK DRM driver. Signed-off-by:

Currently, disconnecting a USB webcam while it is in use prints out a number of warnings, such as: WARNING: CPU: 2 PID: 3118 at /build/linux-ezBi1T/linux-4.8.0/fs/sysfs/group.c:237 sysfs_remove_group+0x8b/0x90 sysfs group ffffffffa7cd0780 not found for kobject 'event13' This has been noticed before. [0] This is because of the order in which things are torn down. If there are no streams active during a USB disconnect: - uvc_disconnect() is invoked via device_del() through the bus notifier mechanism. - this calls uvc_unregister_video(). - uvc_unregister_video() unregisters the video device for each stream, - because there are no streams open, it calls uvc_delete() - uvc_delete() calls uvc_status_cleanup(), which cleans up the status input device. - uvc_delete() calls media_device_unregister(), which cleans up the media device - uvc_delete(), uvc_unregister_video() and uvc_disconnect() all return, and we end up back in device_del(). - device_del() then cleans up the sysfs folder for the camera with dpm_sysfs_remove(). Because uvc_status_cleanup() and media_device_unregister() have already been called, this all works nicely. If, on the other hand, there *are* streams active during a USB disconnect: - uvc_disconnect() is invoked - this calls uvc_unregister_video() - uvc_unregister_video() unregisters the video device for each stream, - uvc_unregister_video() and uvc_disconnect() return, and we end up back in device_del(). - device_del() then cleans up the sysfs folder for the camera with dpm_sysfs_remove(). Because the status input device and the media device are children of the USB device, this also deletes their sysfs folders. - Sometime later, the final stream is closed, invoking uvc_release(). - uvc_release() calls uvc_delete() - uvc_delete() calls uvc_status_cleanup(), which cleans up the status input device. Because the sysfs directory has already been removed, this causes a WARNing. - uvc_delete() calls media_device_unregister(), which cleans up the media device. Because the sysfs directory has already been removed, this causes another WARNing. To fix this, we need to make sure the devices are always unregistered before the end of uvc_disconnect(). To this, move the unregistration into the disconnect path: - split uvc_status_cleanup() into two parts, one on disconnect that unregisters and one on delete that frees. - move v4l2_device_unregister() and media_device_unregister() into the disconnect path.

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 last buffer is often signaled by an empty buffer with the V4L2_BUF_FLAG_LAST flag set.

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.

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.

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: -
