Linux kernel source tree
6405f5b70b
The metadata saved in the ADS is read by GuC when it's initialized. Saving the addresses to the LRCs when they are populated is too late as GuC will keep using the old ones. This was causing GuC to use the RCS LRC for any engine class. It's not a big problem on a Linux-only scenario since the they are used by GuC only on media engines when the watchdog is triggered. However, in a virtualization scenario with Windows as the VF, it causes the wrong LRCs to be loaded as the watchdog is used for all engines. Fix it by letting guc_golden_lrc_init() initialize the metadata, like other *_init() functions, and later guc_golden_lrc_populate() to copy the LRCs to the right places. The former is called before the second GuC load, while the latter is called after LRCs have been recorded.

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.
