![]() The addresses of two elements of the segmap[][] member are passed to the
hardware which expects 128-bit aligned addresses. However, without this
patch offsetof(struct rkvdec_vp9_priv_tbl, segmap[0]) is an odd number
(2421) but the hardware just ignores the 5 least significant bits of the
address. As a result, the hardware writes the segmentation map to incorrect
locations.
Inserting 11 bytes of padding corrects this situation by making the said
addresses divisible by 16 (i.e. aligned on a 128-bit boundary).

README
Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
