[PATCH v6 0/5] media: verisilicon: HEVC: fix 10bits handling

[PATCH v6 0/5] media: verisilicon: HEVC: fix 10bits handling

[Benjamin Gaignard]

When decoding a 10bits bitstreams HEVC driver should only expose 10bits pixel formats.
To fulfill this requirement it is needed to call hantro_reset_raw_fmt()
and to only change driver internal state in case of success.

Fluster score (140/147) doesn't change after this series.

version 6:
- Split the patches in multiple sub-patches.
- Rework hantro_reset_encoded_fmt() usage.

version 5:
- Add Nicolas's review tags
- Add Fixes tags

version 4:
- Split the change in 2 patches.
- Change hantro_check_depth_match() prototype to avoid using
  ctx->bit_depth
- Return the result of hantro_reset_raw_fmt() to the caller.
- Only set ctx->bit_depth when hantro_reset_raw_fmt() returns is ok.

Benjamin Gaignard (5):
  media: verisilicon: Do not set context src/dst formats in reset
    functions
  media: verisilicon: Do not use ctx fields as format storage when
    resetting
  media: verisilicon: Do not set ctx->bit_depth in hantro_try_ctrl()

[PATCH v6 1/5] media: verisilicon: Do not set context src/dst formats in reset functions

[Benjamin Gaignard]

Setting context source and destination formats should only be done
in hantro_set_fmt_out() and hantro_set_fmt_cap() after check that
the targeted queue is not busy.
Remove these calls from hantro_reset_encoded_fmt() and
hantro_reset_raw_fmt() to clean the driver.

[PATCH v6 3/5] media: verisilicon: Do not set ctx->bit_depth in hantro_try_ctrl()

[Benjamin Gaignard]

In hantro_try_ctrl() we should only check the values inside
control parameters and not set ctx->bit_depth. That must
be done in controls set function.
Create a set control function for hevc where ctx->bit_depth is
set at the right time.

[PATCH v6 3/5] media: verisilicon: Do not set ctx->bit_depth in hantro_try_ctrl()

[Benjamin Gaignard]

In hantro_try_ctrl() we should only check the values inside
control parameters and not set ctx->bit_depth. That must
be done in controls set function.
Create a set control function for hevc where ctx->bit_depth is
set at the right time.

Fixes: dc39473d0340 ("media: hantro: imx8m: Enable 10bit decoding")

[PATCH v6 4/5] media: verisilicon: Do not change context bit depth before validating the format

[Benjamin Gaignard]

It is needed to check if the proposed pixels format is valid before
updating context bit depth and other internal states.
Stop using ctx->bit_depth to check format depth match and return
result to the caller.

Fixes: dc39473d0340 ("media: hantro: imx8m: Enable 10bit decoding")

The default bit_depth should be 8,
since 0 is not a valid value.

This should be removed, since now bit_depth will always
be 8 or 10.

Given hantro_reset_raw_fmt sets the state, I suspect it will be better
to store ctx->bit_depth here.

This will also take care of the bit_depth initialization,
at open() time, which is done with hantro_reset_fmts().

In fact, if you want this to be extra robust replace
the integer bit_depth with an enum type, and so we will
guarantee only valid values, 8 or 10 are ever used.

Thanks!
Ezequiel

The default bit_depth should be 8,
since 0 is not a valid value.

This should be removed, since now bit_depth will always
be 8 or 10.

Given hantro_reset_raw_fmt sets the state, I suspect it will be better
to store ctx->bit_depth here.

This will also take care of the bit_depth initialization,
at open() time, which is done with hantro_reset_fmts().

In fact, if you want this to be extra robust replace
the integer bit_depth with an enum type, and so we will
guarantee only valid values, 8 or 10 are ever used.

Thanks!

[PATCH v6 5/5] media: verisilicon: HEVC: Only propose 10 bitscompatible pixels formats

[Benjamin Gaignard]

When decoding a 10bits bitstreams HEVC driver should only expose
10bits pixel formats.
To fulfill this requirement it is needed to call hantro_reset_raw_fmt()
when bit depth change and to correctly set match_depth in pixel formats
enumeration.

Fixes: dc39473d0340 ("media: hantro: imx8m: Enable 10bit decoding")

[PATCH v6 5/5] media: verisilicon: HEVC: Only propose 10 bitscompatible pixels formats

[Benjamin Gaignard]

When decoding a 10bits bitstreams HEVC driver should only expose
10bits pixel formats.
To fulfill this requirement it is needed to call hantro_reset_raw_fmt()
when bit depth change and to correctly set match_depth in pixel formats
enumeration.

Fixes: dc39473d0340 ("media: hantro: imx8m: Enable 10bit decoding")
