Hello Laurent,
I was working on having a functional IOMMU/ISP for 3.14, and had an
issue with an image completely distorted. Comparing with another kernel,
I saw that PRV_HORZ_INFO and PRV_VERT_INFO differed. On the newer
kernel, sph, eph, svl, and slv were all off-by 2, causing my final image
to miss 4 pixels on each line, thus distorting the result.
Your commit 3fdfedaaa7f243f3347084231c64f6c1be0ba131 '[media] omap3isp:
preview: Lower the crop margins' indeed changes PRV_HORZ_INFO and
PRV_VERT_INFO by removing the if() condition. Reverting it made my image
to be valid again.
FYI, my pipeline is:
MT9V032 (SGRBG10 752x480) - CCDC - PREVIEW (UYVY 752x480) - RESIZER
- out
Just an XMAS ping on this :-) Do you have any idea how to solve this
without reverting the patch?
The patch indeed changed the preview engine margins, but the change is
supposed to be handled by applications. As a base for this discussion could
you please provide the media-ctl -p output before and after applying the patch
? You can strip the unrelated media entities out of the output.
