For performance and multi-chip support, use dynamic layout instead of
statically configured pools.
Divide the shared memory into the 3 64-bit aligned layouts listed below:
vpu->param_addr -> +-----------------------------------------+
| |
| To SCP : Input frame parameters |
| (struct img_ipi_frameparam) |
| |
+-----------------------------------------+
vpu->work_addr -> +-----------------------------------------+
| |
| In SCP : Reserve for SCP calculation |
| |
+-----------------------------------------+
vpu->config_addr -> +-----------------------------------------+
| |
| From SCP : Output component config |
| (struct img_config) |
| |

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.
