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 v3:
- Addressed review comments by Andrzej Hajda.
- Addressed review comments by Hans Verkuil.
- Addressed review comments by Julia Lawall.
- Rebased on latest git://linuxtv.org/snawrocki/samsung.git for-v4.12/media/next.
- Applied r-o-b from Andrzej on respective patches.

* [Patch v4 03/12] [media] s5p-mfc: Use min scratch buffer size as provided by F/W

From: Smitha T Murthy @ 2017-04-06 6:11 UTC (permalink / raw)
To: linux-arm-kernel
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.

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.

Please make sure the names are no longer than 31 characters to avoid
truncation during control enumeration in user space.
Data structures like struct v4l2_queryctrl, struct v4l2_query_ext_ctrl
have only 32 bytes long array dedicated for the control name.

Using single letter L instead of LAYER would make the control ID shorter
and more consistent with existing controls, e.g.
V4L2_CID_MPEG_VIDEO_HEVC_HIER_CODING_L6_BITRATE.

I will try to make the names less than 31 characters long without losing
the context. But there are many control names in this file which are
longer than 31 characters like
V4L2_CID_MPEG_VIDEO_H264_HIERARCHICAL_CODING_LAYER_QP,
V4L2_CID_MPEG_VIDEO_VPX_GOLDEN_FRAME_REF_PERIOD etc so I assumed it was
alright to have such long names. But I will shorten them as per your
suggestion.

I will try to make the names less than 31 characters long without losing
the context. But there are many control names in this file which are
longer than 31 characters like
V4L2_CID_MPEG_VIDEO_H264_HIERARCHICAL_CODING_LAYER_QP,
V4L2_CID_MPEG_VIDEO_VPX_GOLDEN_FRAME_REF_PERIOD etc so I assumed it was
alright to have such long names. But I will shorten them as per your
suggestion.

Apologies if it wasn't clean enough but my comment referred to the
length of the character string being returned (e.g. "HEVC LF Across
Slice Boundary or Not") and not to the name of the enum.

You need to add the type of the control in parenthesis. It is probably '(integer)'
for this one. Just follow what is done for other controls.

So "one modulo time" == "one second"? Perhaps just say that instead?

I'd drop this last line. The range you specify already indicates that it can
be negative.

Ditto. Please check this document for more mis-use of the term "control ID", I won't

Demanding in terms of bit rate, i.e. requiring high bit rate? It's a bit
unclear here.

"Setting this control to 0 enables loop filtering, setting this control
to 1 disables loop filtering." ?
Couldn't the meaning be inverted, so setting the control to 0 disables
the loop filtering?

I don't think second sentence is needed.

Could you avoid "disables the control ID", "enables control ID" phrases?
And instead describe indirectly what behaviour corresponds to each value of the
control? So the last sentence becomes something like:
"Setting the control to 0 disables ..., setting the control to 1 enables..."

s/thorugh/through/
s/SIZE_OF_LENGTH_FIELD/V4L2_CID_MPEG_VIDEO_HEVC_SIZE_OF_LENGTH_FIELD control.
I would also drop "among 1,2 or 4" as this information belongs to the
V4L2_CID_MPEG_VIDEO_HEVC_SIZE_OF_LENGTH_FIELD control's description.

Again, please specify explicitly what behaviour corresponds to each value
of the control.

For the above controls it is not clear if these are boolean controls
and which value corresponds to what behaviour.

"Setting the control to 0 disables generating SPS, PPS at every IDR,
setting the control to 1 enables generating SPS, PPS at every IDR."
How about using MFC10 instead of MFC1010 for the controls IDs?

Demanding in terms of bit rate, i.e. requiring high bit rate? It's a bit
unclear here.

"Setting this control to 0 enables loop filtering, setting this control
to 1 disables loop filtering." ?
Couldn't the meaning be inverted, so setting the control to 0 disables
the loop filtering?

Could you avoid "disables the control ID", "enables control ID" phrases?
And instead describe indirectly what behaviour corresponds to each value of the
control? So the last sentence becomes something like:
"Setting the control to 0 disables ..., setting the control to 1 enables..."

s/thorugh/through/
s/SIZE_OF_LENGTH_FIELD/V4L2_CID_MPEG_VIDEO_HEVC_SIZE_OF_LENGTH_FIELD control.
I would also drop "among 1,2 or 4" as this information belongs to the
V4L2_CID_MPEG_VIDEO_HEVC_SIZE_OF_LENGTH_FIELD control's description.

Again, please specify explicitly what behaviour corresponds to each value
of the control.

For the above controls it is not clear if these are boolean controls
and which value corresponds to what behaviour.

"Setting the control to 0 disables generating SPS, PPS at every IDR,
setting the control to 1 enables generating SPS, PPS at every IDR."
How about using MFC10 instead of MFC1010 for the controls IDs?

There are various version of MFC10 like MFCv10.0, MFC v10.10, MFCv10.11,
MFCv10.20. I will check if these controls are specific to MFCv10.10, if
not I will change it to MFC10.
Thank you for the review.

There are various version of MFC10 like MFCv10.0, MFC v10.10, MFCv10.11,
MFCv10.20. I will check if these controls are specific to MFCv10.10, if
not I will change it to MFC10.

OK, this is true for our specific hardware/firmware implementation.
In general, for this user space interface I would rather define that
boolean control so value 1 enables LF and value 0 disables LF.
The driver could simply negate the value when writing registers.
BTW we might need to specify type of the control here as Hans suggested
commenting on other control.

Smitha, do you have any updates on this? IIRC, there were few things
which needed corrections but we were rather close to the final version.
