Commit Message

Benjamin Gaignard Jan. 19, 2023, 8:47 a.m. UTC
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")

Signed-off-by: Benjamin Gaignard <benjamin.gaignard@collabora.com>
---
version 3:
- Propagate hantro_reset_raw_fmt() error.
  I hope I have correctly understood Ezekiel's thoughts 
  in the way I have implemented them.

version 2:
- Remove struct hantro_ctx *ctx variable in hantro_try_ctrl()
  because it isn't used anymore.

While this match 1:1 with the review comment (chain EBUSY), it does not
conceptually solved the problem since we always modify ctx here, and then modify
it futher into hantro_reset_raw_fmt() before we actually check if the queue is
busy. The code needs to be reorganize to check first, and modify after. Its
quite likely that bit_depth should be a parameter to hantro_reset_raw_fmt() so
we don't spread out the logic.

regards,
Nicolas

Oh dammit this is wrong! The try_ctrl shouldn't be changing state!
I missed this when I reviewed the patch.

Please keep in mind, a "try" API in V4L2 typically just
validates but shouldn't set state.

I'm sure we will soon have a Hantro Rust driver and we will be able
to enforce state mutation rules :)

You cannot simply return hantro_reset_raw() and set the bit_depth
in hantro_ctx.

If hantro_reset_raw fails, you would leave a bad state behind.
