Could you give a little bit more detail on why, what the side effects are ?
Should this be a Fixes: ?

Additional newline should be removed.

Mansur, could you answer to Bryan's comments?

Right so we have
pconstraint.plane_format[0].stride_multiples = 128;
pconstraint.plane_format[0].min_plane_buffer_height_multiple = 32;
and
pconstraint.plane_format[1].stride_multiples = 128;
pconstraint.plane_format[1].min_plane_buffer_height_multiple = 16;
and your patch says if opb_fmt == HFI_COLOR_FORMAT_NV12_UBWC then the we
shouldn't do hfi_session_set_property()
I'm sure that's a fix that works but, I wonder would it be possible to
fix this routine to continue to do hfi_session_set_property() with
updated parameters for opb_fmt == HFI_COLOR_FORMAT_NV12_UBWC ?
Could you drill down into the detail in the commit log a little bit
maybe giving a description of why returning for opb_fmt ==
HFI_COLOR_FORMAT_NV12_UBWC is the right thing to-do instead of adding a
new case to the routine for HFI_COLOR_FORMAT_NV12_UBWC and calling
hfi_session_set_property() ?
Its more for my own education on this topic :) but, also helps somebody
else reading the log to understand what the fix is, why it is done this way.

OK, I think I can answer my own question here.
Technically no since 6XX isn't in the long-term-support kernel but, I'd
suggest adding a "Fixes" anyway, so that other users know to apply this
patch to their trees.
Fixes: bc28936bbba9 ("media: venus: helpers, hfi, vdec: Set actual plane
constraints to FW")

Venus hardware would always go with alignments as 128x32 for WxH
irrespective
of color formats. It happened so (historically) that for NV12 (linear)
format,
usecase started demanding for alignments as 256(interlace) and
512(HEIF), and
hence NV12 was defaulted to align as 512x512 in firmware. This was done
to avoid
carrying multiple alignments for different usecases, since aligning with
512x512
would also align it with 128x32 and 256x256 as well.
For UBWC, there is no need to override the default alignment of 128x32,
hence
the api was added to override default alignments for applicable formats,
in
this case NV12(Linear).

Above details should provide info on the need to set this only for NV12
(linear)
and skip for NV12 (UBWC).

Yes, it should go as "Fixes" tag to above patch which we made for 6xx
recently.
