Since ARM has never been open source friendly on the GPU side of the house, the community has had to create open source drivers for the Mali GPUs. Lima covers the older t4xx and panfrost the newer 6xx/7xx series. Well done to all involved and hopefully this will help ARM head in the right direction. There is also now the ability if you don't have any of the legacy drivers enabled (pre-KMS) to remove all the pre-KMS support code from the core drm, this saves 10% or so in codesize on my machine. i915 also enable Icelake/Elkhart Lake Gen11 GPUs by default, vboxvideo moves out of staging. There are also some rcar-du patches which crossover with media tree but all should be acked by Mauro.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Calling VIDIOC_DQBUF can release the core serialization lock pointed to by vb2_queue->lock if it has to wait for a new buffer to arrive. However, if userspace dup()ped the video device filehandle, then it is possible to read or call DQBUF from two filehandles at the same time. It is also possible to call REQBUFS from one filehandle while the other is waiting for a buffer. This will remove all the buffers and reallocate new ones. Removing all the buffers isn't the problem here (that's already handled correctly by DQBUF), but the reallocating part is: DQBUF isn't aware that the buffers have changed. This is fixed by setting a flag whenever the lock is released while waiting for a buffer to arrive. And checking the flag where needed so we can return -EBUSY.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Media Device Allocator API to allows multiple drivers share a media device. This API solves a very common use-case for media devices where one physical device (an USB stick) provides both audio and video. When such media device exposes a standard USB Audio class, a proprietary Video class, two or more independent drivers will share a single physical USB bridge. In such cases, it is necessary to coordinate access to the shared resource. Using this API, drivers can allocate a media device with the shared struct device as the key. Once the media device is allocated by a driver, other drivers can get a reference to it. The media device is released when all the references are released.

Since v4l2-subdev.c was the only place where media_entity_get/put was called, just move the functionality to v4l2-subdev.c and drop those confusing entity functions.

* media: vb2: add buf_out_validate callbackHans Verkuil2019-01-311-0/+5
| | | | | | | | | | | | | | | | | | | | | | When queueing a buffer to a request the 'field' value is not validated. That field is only validated when the _buf_prepare() is called, which happens when the request is queued. However, this validation should happen at QBUF time, since you want to know about this as soon as possible. Also, the spec requires that the 'field' value is validated at QBUF time. This patch adds a new buf_out_validate callback to validate the output buffer at buf_prepare time or when QBUF queues an unprepared buffer to a request. This callback is mandatory for output queues that support requests. This issue was found by v4l2-compliance since it failed to replace V4L2_FIELD_ANY by a proper field value when testing the vivid video output in combination with requests.
