The ROM/firmware state handling has changed between CAVS and ACE architecture: CAVS: ROM and firmware uses the SRAM window for the state and status/error code reporting ACE: ROM code is using two registers to report the state and error while the firmware is using the SRAM window to report states and status/error codes. Use the generic hda_dsp_get_state() to decode ROM state and error codes and print out the firmware state and status/error code only if the SRAM window is accessible - the firmware is booted and the Status readout is not 0xffffffff.

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.
