The host1x CDMA push buffer is terminated by a special opcode (RESTART) that tells the CDMA to wrap around to the beginning of the push buffer. To accomodate the RESTART opcode, an extra 4 bytes are allocated on top of the 512 * 8 = 4096 bytes needed for the 512 slots (1 slot = 2 words) that are used for other commands passed to CDMA. This requires that two memory pages are allocated, but most of the second page (4092 bytes) is never used. Decrease the number of slots to 511 so that the RESTART opcode fits within the page. Adjust the push buffer wraparound code to take into account push buffer sizes that are not a power of two. Signed-off-by: Thierry Reding <treding@nvidia.com> |

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.
