The affected CPU table (cpu_vuln_blacklist) marks Alderlake and Raptorlake P-only parts affected by RFDS. This is not true because only E-cores are affected by RFDS. With the current family/model matching it is not possible to differentiate the unaffected parts, as the affected and unaffected hybrid variants have the same model number. Add a cpu-type match as well for such parts so as to exclude P-only parts being marked as affected. Note, family/model and cpu-type enumeration could be inaccurate in virtualized environments. In a guest affected status is decided by RFDS_NO and RFDS_CLEAR bits exposed by VMMs. Signed-off-by: Pawan Gupta <pawan.kumar.gupta@linux.intel.com> Signed-off-by: Borislav Petkov (AMD) <bp@alien8.de> Signed-off-by: Ingo Molnar <mingo@kernel.org> Acked-by: Dave Hansen <dave.hansen@linux.intel.com> Link: https://lore.kernel.org/r/20250311-add-cpu-type-v8-5-e8514dcaaff2@linux.intel.com
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.
