Linux kernel source tree
821f5fe4db
Starting with Zen6, AMD's Scalable MCA systems will incorporate two new bits in MCA_STATUS and MCA_CONFIG MSRs. These bits will indicate if a valid System Physical Address (SPA) is present in MCA_ADDR. PhysAddrValidSupported bit (MCA_CONFIG[11]) serves as the architectural indicator and states if PhysAddrV bit (MCA_STATUS[54]) is Reserved or if it indicates validity of SPA in MCA_ADDR. PhysAddrV bit (MCA_STATUS[54]) advertises if MCA_ADDR contains valid SPA or if it is implementation specific. Use and prefer MCA_STATUS[PhysAddrV] when checking for a usable address.

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.
