[PATCH v2 0/7] media: hantro: Add 10-bit support

[PATCH v2 0/7] media: hantro: Add 10-bit support

[Jernej Skrabec]

This series adds support for 10-bit format handling in Hantro driver.
Most patches adjust postproc behaviour to be more universal. There is
a lot of assumptions, which need to be replaced with more generalized.

Tested on Allwinner H6. Tested with vp92-2-20-10bit-yuv420.webm sample,
which produces correct checksum.

Please take a look.

Best regards,
Jernej

Changes from RFC:
- fixed typo in function name
- removed merged patch (P010 format)
- removed broken patch (sunxi frequency change)
- added new patch (media: hantro: postproc: Properly calculate chroma offset)
- added r-b from Ezequiel

[PATCH v2 2/7] media: hantro: Support format filtering by depth

[Jernej Skrabec]

In preparation for supporting 10-bit formats, add mechanism which will
filter formats based on pixel depth.

Hantro G2 supports only one decoding format natively and that is based
on bit depth of current video frame. Additionally, it makes no sense to
upconvert bitness, so filter those out too.

[PATCH v2 2/7] media: hantro: Support format filtering by depth

[Jernej Skrabec]

In preparation for supporting 10-bit formats, add mechanism which will
filter formats based on pixel depth.

Hantro G2 supports only one decoding format natively and that is based
on bit depth of current video frame. Additionally, it makes no sense to
upconvert bitness, so filter those out too.

[PATCH v2 3/7] media: hantro: postproc: Fix buffer size calculation

[Jernej Skrabec]

When allocating aux buffers for postprocessing, it's assumed that base
buffer size is the same as that of output. Coincidentally, that's true
most of the time, but not always. 10-bit source also needs aux buffer
size which is appropriate for 10-bit native format, even if the output
format is 8-bit. Similarly, mv sizes and other extra buffer size also
depends on source width/height, not destination.

[PATCH v2 3/7] media: hantro: postproc: Fix buffer size calculation

[Jernej Skrabec]

When allocating aux buffers for postprocessing, it's assumed that base
buffer size is the same as that of output. Coincidentally, that's true
most of the time, but not always. 10-bit source also needs aux buffer
size which is appropriate for 10-bit native format, even if the output
format is 8-bit. Similarly, mv sizes and other extra buffer size also
depends on source width/height, not destination.

[PATCH v2 5/7] media: hantro: postproc: Properly calculate chroma offset

[Jernej Skrabec]

Currently chroma offset calculation assumes only 1 byte per luma, with
no consideration for stride.

Take necessary information from destination pixel format which makes
calculation completely universal.

I have send a complementary series to this one to enable 10-bit
for HEVC on Hantro/G2 on IMX8MQ.
With these two patchset I'm able to decode all the 10-bit conformance
test files.

Clearly this is correct.

When the driver enables the post-processor it decodes a coded format (H264, etc.)
to a native format (NV12_4L4 or P010_4L4) and feeds this into the postprocessor
engine to produce some other format (YUYV, NV12, etc.).

The buffers allocated here should be taken from the native format,
so it's correct to use hantro_get_default_fmt().

The issue comes at this point, where we negotiate the buffer size based on the
source size (OUTPUT queue size), instead of negotiating based
on the Native size.

  Coded -> [ Decoder ] -> Native -> [ Post-processor ] -> Decoded

So, while the patch is surely improving things, I wonder if it won't
cause other issues.

This reminds me we are still lacking a more complete test-suite for this
driver, so that we can validate changes and ensure there are no
regressions.

Perhaps we could hack Fluster to not only test the conformance,
but also test the post-processor?

Thanks,
Ezequiel

Clearly this is correct.

When the driver enables the post-processor it decodes a coded format (H264, etc.)
to a native format (NV12_4L4 or P010_4L4) and feeds this into the postprocessor
engine to produce some other format (YUYV, NV12, etc.).

The buffers allocated here should be taken from the native format,
so it's correct to use hantro_get_default_fmt().

The issue comes at this point, where we negotiate the buffer size based on the
source size (OUTPUT queue size), instead of negotiating based
on the Native size.

  Coded -> [ Decoder ] -> Native -> [ Post-processor ] -> Decoded

So, while the patch is surely improving things, I wonder if it won't
cause other issues.

This reminds me we are still lacking a more complete test-suite for this
driver, so that we can validate changes and ensure there are no
regressions.

Perhaps we could hack Fluster to not only test the conformance,
but also test the post-processor?

  Coded -> [ Decoder ] -> Native -> [ Post-processor ] -> Decoded

So, while the patch is surely improving things, I wonder if it won't

Perhaps we could hack Fluster to not only test the conformance,

I'm not sure what is the difference between source and native size? You mean 
one coded in controls and one set via output format? IMO they should always be 
the same, otherwise it can be considered a bug in userspace application.

I'm not sure what is the difference between source and native size? You mean 
one coded in controls and one set via output format? IMO they should always be 
the same, otherwise it can be considered a bug in userspace application.

We also need to add the documentation in
Documentation/userspace-api/media/v4l/pixfmt-yuv-planar.rst.

See Benjamin's patch for reference:

commit 5374d8fb75f313294c7d97e85c22bead34d63f2b

    media: Add P010 video format

    P010 is a YUV format with 10-bits per component with interleaved UV.

I would make this "10-bit Y/CbCr 4:2:0 (4x4 Linear)".

Indeed the src_fmt should use coded width/height (as per spec). The driver will
then adapt to its own requirement resulting into the "native" width height being
returned. Notice that s_ctrl() should fail in case of miss-match (this is CODEC
specific), or streamon() should fail if the codec specific control have never
been set (as we always initialise this, it will fail due to default being an
invalid value anyway).

As a side effect, when userland read the default format (G_FMT(CAPTURE), the
width/height should match the src_dst for this driver. This is the native size.
The optional path that this driver enables is enumeration of CAPTURE format and
frame sizes, combined with to select from these. The driver will create a
secondary set of buffers in the case.

Indeed the src_fmt should use coded width/height (as per spec). The driver will
then adapt to its own requirement resulting into the "native" width height being
returned. Notice that s_ctrl() should fail in case of miss-match (this is CODEC
specific), or streamon() should fail if the codec specific control have never
been set (as we always initialise this, it will fail due to default being an
invalid value anyway).

As a side effect, when userland read the default format (G_FMT(CAPTURE), the
width/height should match the src_dst for this driver. This is the native size.
The optional path that this driver enables is enumeration of CAPTURE format and
frame sizes, combined with to select from these. The driver will create a
secondary set of buffers in the case.

Since this affects the possible formats, shouldn't it reset
the decoded format?

In other words, it would mean calling hantro_reset_raw_fmt().

Hopefully, that would be OK and not cause any weird issues?

Nicolas, any feedback?
