[Patch v6 00/12] Add MFC v10.10 support

[Smitha T Murthy]

This patch series adds MFC v10.10 support. MFC v10.10 is used in some
of Exynos7 variants.

This adds support for following:

* Add support for HEVC encoder and decoder
* Add support for VP9 decoder
* Update Documentation for control id definitions
* Update computation of min scratch buffer size requirement for V8 onwards

Changes since v5:
 - Addressed review comments by Kamil Debski <kamil@wypas.org>.
 - Addressed review comments by 
   Stanimir Varbanov <stanimir.varbanov@linaro.org>.
 - Addressed review comments by Hans Verkuil <hverkuil@xs4all.nl>.
 - Rebased on latest git://linuxtv.org/snawrocki/samsung.git
   for-v4.15/media/next.
 - Applied r-o-b from Andrzej, Stanimir on respective patches.
 - Applied acked-by from Kamil, Hans on respective patches.

[Patch v6 01/12] [media] s5p-mfc: Rename IS_MFCV8 macro

[Smitha T Murthy]

This patch renames macro IS_MFCV8 to IS_MFCV8_PLUS so that the MFCv8
code can be resued for MFCv10.10 support. Since the MFCv8 specific code
holds good for MFC v10.10 also.

Have you considered using the new SPDX ids instead of this fine legalese? e.g.:

// SPDX-License-Identifier: GPL-2.0

This is much shorter and neater (unless you are a legalese lover of
course!)  Check also Thomas doc patches and Linus comments on why he
prefers the C++ comment style for these.

And even better could be this more compact form? I am a big fan of the
C++ style comments for these (and so is Linus)

// SPDX-License-Identifier: GPL-2.0
// Copyright (c) 2017 Samsung Electronics Co., Ltd.
// Register definition file for Samsung MFC V10.x Interface (FIMV) driver

You can also read this fine article from a fellow Samsung colleague
[1]. And if you ever consider doing this for all Samsung's past,
present and future contributions, you will have my deep gratitude

Ok I will change to the SPDX license in the next patch series for the
v10 register file. Correspondingly for the MFC driver's files I will
update the license as a separate patch and submit.

Ah, I forgot about this series. I'll try to review it tomorrow or Monday.

Sorry about the delay,

[Patch v6 03/12] [media] s5p-mfc: Use min scratch buffer size as provided by F/W

[Smitha T Murthy]

After MFC v8.0, mfc f/w lets the driver know how much scratch buffer
size is required for decoder. If mfc f/w has the functionality,
E_MIN_SCRATCH_BUFFER_SIZE, driver can know how much scratch buffer size
is required for encoder too.

Wouldn't it be more consistent to call it V4L2_PIX_FMT_H265 as we have
used H264 for the previous generation, or is there a formal rationale ?
Also, this is byte-stream right ? With start codes ?

It would, but what I'm afraid on using specs name here, due to what
happened with MPEG-4 specs. Originally, it was referred to one codec
(ASP). Then, part 10 came with a different compression codec (AVC). So,
now, when referring to MPEG-4, one need to explicitly mention if the code
is AVC or not. The ITU-T didn't make the same mistake (yet?), but nobody
can predict what will happen in the future.

So, now that an spec can be modified to include additional parts with
different codecs, it sounds less risky to use the codec name instead
of the spec number, as this shouldn't change :-)

Yes true, also to keep the uniformity I will change for all
V4L2_CID_MPEG_VIDEO_HEVC_HIER_CODING_L1_QP and
V4L2_CID_MPEG_VIDEO_HEVC_HIER_CODING_L0_BR "Lay" with "L".

These strings are too long by one character. Perhaps replace "Bit Rate" by "Bitrate"?

Just to confirm: all these new controls all refer to settings that are part of the
HEVC standard, right? I.e. none of them are specific to the MFC implementation.

I believe I asked this before for older versions of this series, but it's been
a while, so I'd better check again.

Not sure what you mean with "Number gaps are for compatibility". There are no gaps
and since this is a new API, there are also no compatibility issues.

Each new codec skips to a new range, so I would suggest to start counting at 600 instead of 512.

I assume these values all have to be in the range MIN_QP to MAX_QP?
If so, then this should be documented I think.

How do these controls relate to MIN_QP and MAX_QP?

Should this perhaps be a bool instead of an enum? Assuming this represents a
single bit. I'm not saying enum is wrong, I just wondered what makes the most
sense.

Can you add the full name for IDR in brackets, just as you did for CRA?

I had initially kept it as boolean but Andrzej asked me to change it to
enum [https://patchwork.kernel.org/patch/9655731/]

[Patch v6 00/12] Add MFC v10.10 support

[Hans Verkuil]

Hi Smitha,

Thank you for this v6 series!

You can add my:

Acked-by: Hans Verkuil <hans.verkuil@cisco.com>

to patches 1-9 and 11. See my review for patches 10 and 12. The comments
are minor, so I hope I can Ack v7 once it's posted and this can be merged
for 4.17.

Regards,

	Hans
