This is actually already indirectly mentioned in the comment, but smaller size is used nevertheless. Increase buffer size to cover H6 needs. Since increase is not that big in absolute numbers, it doesn't make sense to complicate logic for older generations. Bug was discovered using iommu, which reported access error when trying to play H265 video.
