Linux kernel source tree
d9207cf776
When doing error injection to some memory DIMMs on certain Intel Emerald
Rapids servers, the i10nm_edac missed error reports for some memory DIMMs.
Certain BIOS configurations may hide some memory controllers, and the
i10nm_edac doesn't enumerate these hidden memory controllers. However, the
ADXL decodes memory errors using memory controller physical indices even
if there are hidden memory controllers. Therefore, the memory controller
physical indices reported by the ADXL may mismatch the logical indices
enumerated by the i10nm_edac, resulting in missed error reports for some
memory DIMMs.
Fix this issue by creating a mapping table from memory controller physical
indices (used by the ADXL) to logical indices (used by the i10nm_edac) and
using it to convert the physical indices to the logical indices during the
error handling process.

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.
