The HDA specification states that the SDnLVI (Last Valid Index) must be at least 1 (two BDLE entry). Update the debug prints as well to provide better information. While the LVI=0 worked so far without issues, it is better to align with the specification to avoid unforeseen issues with FW loading. Notes: - The LVI > 0 rules is valid and honored for audio use cases - LVI == 0 is used with software controlled (SPIB) transfers only for firmware and library loading, which is permitted by the hardware - This is not spelled out in the specification and it is better to avoid cases Signed-off-by: Peter Ujfalusi <peter.ujfalusi@linux.intel.com> Reviewed-by: Liam Girdwood <liam.r.girdwood@intel.com> Reviewed-by: Kai Vehmanen <kai.vehmanen@linux.intel.com> Reviewed-by: Bard Liao <yung-chuan.liao@linux.intel.com> Link: https://patch.msgid.link/20241107121532.3241-1-peter.ujfalusi@linux.intel.com Signed-off-by: Mark Brown <broonie@kernel.org>
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.
