Platform: RV1126B Err log: mpp_rkvdec2 22140100.rkvdec: session 94 task 47772 timeout 1 abort 0 force_deq0 mpp_rkvdec2 22140100.rkvdec: resetting... mpp_rkvdec2 22140100.rkvdec: reset timeout mpp_rkvdec2 22140100.rkvdec: reset done mpp_rkvdec2 22140100.rkvdec: resend task 47773 mpp_rkvdec2 22140100.rkvdec: resend task 47774 Err case: When the zap mmu is issued, it causes the mmu to issue an additional table fetch command. The data returned by this additional table fetch command happens to fall during the clock-off period of the reset, resulting in an incomplete final bus. Solution: The software should not zap the MMU while the hardware is operating. Instead, the 1126B can rely on its built-in hardware MMU zap functionality.

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.
