When output encoded buffer size provided by userspace is insufficient with current encoding parameters, it leads to RET_ENC_BUFFER_FULL interrupt which was not handled in IRQ handler. On handling of RET_ENC_BUFFER_FULL interrupt leads to NAL_ABORT command from host to risc which in turn leads to RET_NAL_ABORT interrupt. On receiving RET_NAL_ABORT driver clears workbit and VB2 queues for cleaner closing of MFC instance. When user encounters "Call on DQBUF after unrecoverable error", userspace should close fd and restart with larger output encoder buffer size.

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 reStructuredText 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.
