2018-07-25media: venus: implementing multi-stream supportStanimir Varbanov5-4/+300
This is implementing multi-stream decoder support. The multi-stream will be used to enable/disable the primary/secondary decoder outputs. Depending on formats on both decoder outputs we could implement downscale, dithering and supporting UBWC (universal bandwidth compression) formats. The UBWC compressed raw format is used to optimize interconnect bandwidth for bigger resolutions like 4K and hence we will get some power-saving benefits as well. Both decoder outputs are distinguished by buffer_type field in the HFI packets. For example HFI_BUFFER_OUTPUT is the buffer type for primary decoder output and HFI_BUFFER_OUTPUT2 is for secondary decoder output. Starting from Venus 4xx the DPB buffers format must be UBWC, so the multi-stream becomes mandatory for this Venus version. That means that we need to allocate internally in the driver a set of DPB buffers (with UBWC NV12 format) and give them to the firmware. The other decoder output (we called it OPB) format will be NV12 linear format and with the same resolution (or smaller in case the user wants to downscale). The DPB buffers are used for decoder reference frames and those have to be in a specific format (UBWC). So one decoder output is used to fill those reference buffers while the other output is used to fill the userspace buffers with the user requested format.

The use of 'DTV' is very confusing since it normally refers to Digital TV e.g. DVB etc. Instead use 'DV' (Digital Video), which nicely corresponds to the DV Timings API used to configure such receivers and transmitters. We keep an alias to avoid breaking userspace applications. Since this alias is only available if __KERNEL__ is *not* defined (i.e. it is only available for userspace, not kernelspace), any drivers that use it also have to be converted to the new define.

Commit 1d3897143815 ("[media] v4l: rcar_fdp1: add FCP dependency") fixed a compilation breakage when the optional VIDEO_RENESAS_FCP dependency is compiled as a module while the rcar_fdp1 driver is built in. As a side effect it disabled compilation on Gen2 by disallowing the valid combination ARCH_RENESAS && !VIDEO_RENESAS_FCP. Fix it by handling the dependency the same way the vsp1 driver did in commit 199946731fa4 ("[media] vsp1: clarify FCP dependency").

2018-07-24media: videobuf2-core: check for q->error in vb2_core_qbuf()Hans Verkuil1-0/+5
The vb2_core_qbuf() function didn't check if q->error was set. It is checked in __buf_prepare(), but that function isn't called if the buffer was already prepared before with VIDIOC_PREPARE_BUF. So check it at the start of vb2_core_qbuf() as well.

2018-07-24media: mem2mem: Make .job_abort optionalEzequiel Garcia7-36/+3
Implementing job_abort() does not make sense on some drivers. This is not a problem, as the abort is not required to wait for the job to finish. Quite the opposite, drivers are encouraged not to wait. Demote v4l2_m2m_ops.job_abort from required to optional, and clean all drivers with dummy implementations.

2018-07-24media: s5p-g2d: Remove unrequired wait in .job_abortEzequiel Garcia2-12/+0
As per the documentation, job_abort is not required to wait until the current job finishes. It is redundant to do so, as the core will perform the wait operation. Remove the wait infrastructure completely.
