[PATCH] hantro: Fix RK3399 H.264 format advertising

[PATCH] hantro: Fix RK3399 H.264 format advertising

[Ezequiel Garcia]

Commit 1f82f2df523cb ("media: hantro: Enable H.264 on Rockchip VDPU2")
enabled H.264 on some SoCs with VDPU2 cores. This had the side-effect
of exposing H.264 coded format as supported on RK3399.

Fix this and clarify how the codec is explicitly disabled on RK399 on
this driver.

[PATCH] hantro: Remove incorrect HEVC SPS validation

[Ezequiel Garcia]

Currently, the driver tries to validat the HEVC SPS
against the CAPTURE queue format (i.e. the decoded format).
This is not correct, because typically the SPS control is set
before the CAPTURE queue is negotiated.

In addition to this, a format validation in hantro_hevc_dec_prepare_run()
is also suboptimal, because hantro_hevc_dec_prepare_run() runs in the context
of v4l2_m2m_ops.device_run, as part of a decoding job.

Format and control validations should happen before decoding starts,
in the context of ioctls such as S_CTRL, S_FMT, or STREAMON.

Remove the validation for now.

Couldn't we add a small wrapper around STREAMON to perform that
validation? I feel like "remove the validation for now", seems like a
vague statement.

I agree. Basically two things happen in this patch: two sanity checks
for the SPS control are moved to try_ctrl, and that part looks good.

So that can be a separate patch.

The second part is the removal of the format+control validation, but it
is not clear why removing it altogether is wrong. Shouldn't it still be
done somewhere? And if not, why not?

Sorry for the delayed reply. After giving this format+control validation
more thought, I believe the V4L2 API provides a natural way of handling.

When the format is negotiated in TRY_FMT, the control needs to be used
to offer a valid resolution.

The driver is capable of negotiating the resolution of the stream
using the control information, instead of failing.

I'll send a v2 with a new proposal.

Thanks,
Ezequiel

Thanks for fixing this. The bogus format (without associated controls) is not
gone. With the right video node value:

  v4l2-ctl -D -dN --list-formats-out

[PATCH] media: destage Hantro VPU driver

[Ezequiel Garcia]

The Hantro mainline driver has been used in production
since several years and was only kept as a staging driver
due the stateless CODEC controls.

Now that all the stateless CODEC controls have been moved
out of staging, graduate the driver as well.

[PATCH] hantro: Remove incorrect HEVC SPS validation

[Ezequiel Garcia]

Currently, the driver tries to validat the HEVC SPS
against the CAPTURE queue format (i.e. the decoded format).
This is not correct, because typically the SPS control is set
before the CAPTURE queue is negotiated.

Fixes: 135ad96cb4d6b ("media: hantro: Be more accurate on pixel formats step_width constraints")

This is actually a v2. I've chosen to move the
control checks back to try_ctrl, but leave the tiled
format alignment check.

This ALIGN() check can be optimized, moving the alignment
to the TRY_FMT step (instead of failing at device_run).
However, this is a minor optimization, so I'd like to
avoid the scope creep, and pospone the changes regarding
the tiled format resolution alignment.

Thanks,
Ezequiel
