The number of 'entry point offset' can be very variable. Instead of using a large static array define a v4l2 dynamic array of U32 (V4L2_CTRL_TYPE_U32). The number of entry point offsets is reported by the elems field and in struct v4l2_ctrl_hevc_slice_params.num_entry_point_offsets field.

The HEVC specification describes the following: "PicOrderCntVal is derived as follows: PicOrderCntVal = PicOrderCntMsb + slice_pic_order_cnt_lsb The value of PicOrderCntVal shall be in the range of −2^31 to 2^31 − 1, inclusive." To match with these definitions change __u16 pic_order_cnt[2] into __s32 pic_order_cnt_val. Change v4l2_ctrl_hevc_slice_params->slice_pic_order_cnt to __s32 too.

Add a new flag that indicates that this control is a dynamically sized array. Also document this flag. Currently dynamically sized arrays are limited to one dimensional arrays, but that might change in the future if there is a need for it. The initial use-case of dynamic arrays are stateless codecs. A frame can be divided in many slices, so you want to provide an array containing slice information for each slice. Typically the number of slices is small, but the standard allow for hundreds or thousands of slices. Dynamic arrays are a good solution since sizing the array for the worst case would waste substantial amounts of memory. Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl>

The error handling code in pvr2_hdw_create forgets to unregister the v4l2 device. When pvr2_hdw_create returns back to pvr2_context_create, it calls pvr2_context_destroy to destroy context, but mp->hdw is NULL, which leads to that pvr2_hdw_destroy directly returns. Fix this by adding v4l2_device_unregister to decrease the refcount of usb interface.

Set allow_cache_hints to 1 for the vb2_queue source and destination queues in the mediatek vcodec V4L2 driver. This allows us to allocate buffers with the V4L2_MEMORY_FLAG_NON_COHERENT set. On Mediatek SoCs, this enables caching for this memory, which vastly improves performance when being read from CPU. Read performance for these buffers is in turn important for detiling MM21 video frames in userspace software, such as libyuv or gstreamer. This change should be safe from race conditions since videobuf2 already invalidates or flushes the appropriate cache lines in its prepare() and finish() methods. Tested on a MT8183 SoC. Resulted in both correct detiling and a 10X speedup.

The hardware can support any image size WxH, with arbitrary W (image width) and H (image height) dimensions. Align upwards buffer size for both encoder and decoder. and leave the picture resolution unchanged. For decoder, the risk of memory out of bounds can be avoided. For both encoder and decoder, the driver will lift the limitation of resolution alignment. For example, the decoder can support jpeg whose resolution is 227x149 the encoder can support nv12 1080P, won't change it to 1920x1072.

Rather than kmalloc/kzalloc + memcpy, which the programmer needs to write the size twice (sometimes lead to mistakes), kmemdup improves readability, leads to smaller code and also reduce the chances of mistakes.

The cropping configuration of the Parallel Front Engine (PFE) can be done just once when the streaming starts. The ISC configuration is in place and will not be changed while streaming. It is not effective to keep rewriting the crop registers configuration everytime start_dma is called, as this can be called for each queued buffer. Thus we can configure the cropping at start_streaming time. This change moves the code to a dedicated function.
