A partitioned system configured with only one package and one compute die, warning will be generated for duplicate sysfs entry. This typically occurs during the platform bring-up phase. Partitioned systems expose dies, equivalent to TPMI compute domains, through the CPUID. Each partitioned system must contains at least one compute die per partition, resulting in a minimum of two dies per package. Hence the function topology_max_dies_per_package() returns at least two, and the condition "topology_max_dies_per_package() > 1" prevents the creation of a root domain. In this case topology_max_dies_per_package() will return 1 and root domain will be created for partition 0 and a duplicate sysfs warning for partition 1 as both partitions have same package ID. To address this also check for non zero partition in addition to topology_max_dies_per_package() > 1.

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.
