2019-01-16media: vivid: take data_offset into account for video outputHans Verkuil1-6/+10
The video output sizeimage calculation did not take data_offset into account. This can cause problems with video loopback or exporting output buffers for use as dmabuf import buffers since the output buffer size is now too small.

2019-01-16media: sun6i: Add H3 compatibleChen-Yu Tsai1-0/+1
The CSI controller found on the H3 (and H5) is a reduced version of the one found on the A31. It only has 1 channel, instead of 4 channels for time-multiplexed BT.656. Since the H3 is a reduced version, it cannot "fallback" to a compatible that implements more features than it supports. Add a compatible string entry for the H3.

This commit corrects max and step values for v4l2 control for V4L2_CID_JPEG_RESTART_INTERVAL. Max should be 0xffff and step should be 1. It was found by using v4l2-compliance tool and checking result of VIDIOC_QUERY_EXT_CTRL/QUERYMENU test. Previously it was complaining that step was bigger than difference between max and min.

2019-01-16media: rcar-vin: remove unneeded locking in async callbacksNiklas Söderlund1-14/+0
The locking implemented in the async notifier callbacks are unnecessary as the global list_lock in v4l2-async.c is held whenever one of the callbacks are called. The locking in itself is not harmful however it produces a LOCKDEP warning between the global v4l2-async list_lock and the rcar-vin local locking schema. Remove the rcar-vin locking for the async callbacks to reduce complexity and silent the false LOCKDEP warning.

Previously when doing format enumeration, it was returning all formats supported by driver, even if they're not supported by hw. Add missing check for fmt_ver_flag, so it'll be fixed and only those supported by hw will be returned. Similar thing is already done in s5p_jpeg_find_format. It was found by using v4l2-compliance tool and checking result of VIDIOC_ENUM_FMT/FRAMESIZES/FRAMEINTERVALS test and using v4l2-ctl to get list of all supported formats.

cancel_delayed_work_sync() was called for any queue, but it should only be called for the queue that is associated with the currently running job. Otherwise, if two filehandles are streaming at the same time, then closing the first will cancel the work which might still be running for a job from the second filehandle. As a result the second filehandle will never be able to finish the job and an attempt to stop streaming on that second filehandle will stall.

2018-12-03media: vicodec: set state resolution from raw formatHans Verkuil1-3/+10
The state structure contains the resolution expected by the decoder and encoder. For an encoder that resolution should be taken from the OUTPUT format, and for a decoder from the CAPTURE format. If the wrong format is picked, a buffer overrun can occur if there is a mismatch between the CAPTURE and OUTPUT formats. The real fix would be to correctly implement the stateful codec specification, but that will take more time. For now just prevent the buffer overrun.

Nothing happened to the request and the state should remain as it was before start_streaming was called.

Commit de2bc45c84f7 ("media: vsp1: Update LIF buffer thresholds") updated the LIF buffer thresholds based on the VSP version, but used the wrong model mask. This resulted in all VSP instances to be treated as a Gen3 VSPD, breaking operation on all Gen2 platforms as well as on H3 ES2.0, M3-N, V3M and V3H. Fix it.

2018-12-03media: mtk-vcodec: Remove VA from encoder frame buffersTomasz Figa3-6/+7
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.
