[PATCH v5 0/5] media: rzg2l-cru: Fix DMA stride alignment

[Tommaso Merciai]

Dear All,

While testing ov5645 + RZ/G3E we found out that the UYVY8_2X8/2592x1944
is broken. The issue is that the CRU DMA engine requires the line stride
to be a multiple of 128 bytes (RZG2L_CRU_STRIDE_ALIGN). v4l2_fill_pixfmt()
sets bytesperline as width * bytes_per_pixel with no alignment, so for
widths whose natural stride is not 128-byte aligned the hardware silently
rounds up, causing a mismatch that produces visible horizontal banding in
the captured image.

Tested using:

media-ctl -d /dev/media0 --set-v4l2 '"ov5645 0-003c":0[fmt:UYVY8_2X8/2592x1944 field:none]'
media-ctl -d /dev/media0 --set-v4l2 '"csi-16000400.csi2":0[fmt:UYVY8_2X8/2592x1944]'
media-ctl -d /dev/media0 --set-v4l2 '"cru-ip-16000000.video":0[fmt:UYVY8_2X8/2592x1944]'

v4l2-ctl -d /dev/video0 --verbose --set-fmt-video=width=2592,height=1944,pixelformat=UYVY --stream-mmap --stream-count=100 --stream-to=./frame.raw
gst-launch-1.0 v4l2src device=/dev/video0 blocksize=76800 io-mode=dmabuf num-buffers=200 ! video/x-raw,format=UYVY,width=2592,height=1944 !  videoconvert ! queue ! waylandsink sync=false

This patch fix the issue.

Kind Regards,
Tommaso

v4->v5:
 - Rebased on top of media-committers/next
 - Split the fix so it no longer depends on v4l2_fill_pixfmt_aligned()
   and moved it first in the series, so it can be backported to stable
   on its own (This the old v4 PATCH 4/4).

[PATCH v5 1/5] media: rzg2l-cru: Align bytesperline to hardware DMA stride requirement

[Tommaso Merciai]

The RZ/G3E CRU programs the line stride via the AMnIS register, whose
IS field encodes the value in units of 128 bytes. If bytesperline is
not a multiple of 128, the division truncates and the hardware uses a
wrong stride, causing horizontal banding.

Commit ace92ccef0c9 ("media: platform: rzg2l-cru: Use v4l2_fill_pixfmt()")
replaced the open-coded aligned calculation with v4l2_fill_pixfmt(),
which sets no alignment, reintroducing the issue.

Round bytesperline up to RZG2L_CRU_STRIDE_ALIGN and recompute
sizeimage when info->has_stride is set. RZ/G2L has no AMnIS register
and keeps the values from v4l2_fill_pixfmt() unchanged.

[PATCH v5 2/5] media: v4l2-common: Convert v4l2_fill_pixfmt_mp() to static inline wrapper

[Tommaso Merciai]

Convert v4l2_fill_pixfmt_mp() to static inline wrapper: drop the exported
v4l2_fill_pixfmt_mp() function from v4l2-common.c and replace it with
an equivalent static inline in the header that delegates to
v4l2_fill_pixfmt_mp_aligned() with stride_alignment=1.

[PATCH v5 3/5] media: v4l2-common: Add v4l2_fill_pixfmt_aligned() helper

[Tommaso Merciai]

Add v4l2_fill_pixfmt_aligned(), a variant of v4l2_fill_pixfmt()
that accepts a stride_alignment parameter, mirroring the existing
v4l2_fill_pixfmt_mp() / v4l2_fill_pixfmt_mp_aligned() pair.

v4l2_fill_pixfmt() is refactored to call v4l2_fill_pixfmt_aligned()
with stride_alignment=1, preserving its existing behaviour.

The new helper is needed by drivers whose DMA engine requires the
line stride to be a multiple of a specific value, such as the
Renesas RZ/G3E CRU which requires 128-byte alignment.

Ack! I think this does what is expected for the single planar formats
the CRU supports!

I think after this cycle you could send a patch to replace the above
back-portable change with the usage of v4l2_fill_pixfmt_aligned().

When you do so, could you consider, replacing "has_stride" with a per
struct rzg2l_cru_info .stride field ?

I think it would look nicer as you could here unconditionally align
(assuming the new .stride will be set to 1 for G2L which currently has
.has_stride = 0).

Also, RZG2L_CRU_STRIDE_ALIGN is a bit of a mis-nomer, as only G3E and
V2H has a AMnIS register and alignments constraints as far as I see.

The only other user of 'has_stride' I see is:

 rzg2l_cru_initialize_axi()

	if (info->has_stride) {
		u32 stride = cru->format.bytesperline;
		u32 amnis;

		stride /= RZG2L_CRU_STRIDE_ALIGN;
		amnis = rzg2l_cru_read(cru, AMnIS) & ~AMnIS_IS_MASK;
		rzg2l_cru_write(cru, AMnIS, amnis | AMnIS_IS(stride));
	}

the G2L has no register AMnIS, so we can't write it unconditionally
but rather replace the check with:

        if (info->stride > 1)

As a bonus, if any other variant will get a different stride, it will
be automatically supported.

What do you think ?
