[PATCH 0/3] media: venus: fix NV12 buffer sizing and incorrect capability alignment

Posted by Renjiang Han 1 day, 17 hours ago

The NV12 frame size calculation adds unnecessary 4K/8K padding, leading
to buffer overallocation. The redundant padding is removed while keeping
final 4K alignment. In addition, HFI platform capabilities advertise an
overly strict 16-pixel alignment for frame and blur dimensions, which
can reject valid userspace configurations. The alignment step is relaxed
to 1 without changing min/max limits.
