Hi,
this is the second version of the i.MX mem2mem scaler series.
Patches 8 and 16 have been modified.
Changes since v1:
- Fix inverted allow_overshoot logic
- Correctly switch horizontal / vertical tile alignment when
determining seam positions with the 90° rotator active.
Yes, this fixes the specific rotation test that was broken
(720x480, UYVY --> 1280x768, UYVY, rotate 90).
But running more tests on this v2 reveals more issues. I chose a
somewhat random upscaling-only example as a first try:
640x480, YV12 --> full HD 2560x1600, YV12 (no rotation or flip).
This produces division by zero backtraces and the conversion hangs:
The hang is apparently because the conversion is re-attempted over and
over again, with an endless WARN() from
drivers/media/common/videobuf2/videobuf2-core.c:900.
I fixed the hang with an additional patch:
50026cbe08 ("media: imx: mem2mem: Remove buffers on device_run failures")
With this the conversion completes, but the below div-by-zero errors
persist, and the resultant image is blank.

tile boundaries.

find_seams(). Can
you provide some more background on the behavior of those functions?

Hello Beautiful
Hi Dear, my name is Jack and i am seeking for a relationship in which i will feel loved after a series of failed relationships. I am hoping that you would be interested and we could possibly get to know each other more if you do not mind. I am open to answering questions from you as i think my approach is a little inappropriate. Hope to hear back from you. Jack.

The input DMA burst width alignment is only necessary if the lines are
scanned from right to left (that is, if HF is enabled) in the scaling
step.
Ok, thanks for the explanation, that makes sense.
If the rotator is used, the flipping is done in the rotation step
instead,
Ah, I missed or forgot about that detail in the ref manual,
I reviewed it again and you are right...
so the alignment restriction would be on the width of the
intermediate tile (and thus on the output height). This is already
covered by the rotator 8x8 pixel block alignment.
so this makes sense too.
That is, require 8 byte width alignment for IRT or if HFLIP is enabled.
No, I specifically meant (!IRT && HFLIP).
Right, but there is still a typo:
if (!ipu_rot_mode_is_irt(ctx->rot_mode) && ctx->rot_mode && IPU_ROT_BIT_HFLIP)
should be:
if (!ipu_rot_mode_is_irt(ctx->rot_mode) && (ctx->rot_mode & IPU_ROT_BIT_HFLIP))
The rotator itself doesn't cause any input alignment restrictions, we
just have to make sure that the intermediate tiles after scaling are 8x8
aligned.
Also, why not simply call ipu_image_convert_adjust() in
mem2mem_try_fmt()? If there is something missing in the former
function, then it should be added there, instead of adding the
missing checks in mem2mem_try_fmt().
ipu_image_convert_adjust tries to adjust both input and output image at
the same time, here we just have the format of either input or output
image. Do you suggest to split this function into an input and an output
version?
See b4362162c0 ("media: imx: mem2mem: Use ipu_image_convert_adjust
in try format")
in my mediatree fork at g...@github.com:slongerbeam/mediatree.git.
Let's discuss this further in the v2 patches.
