Currently when a new resource group is created its allocations would be those that belonged to the resource group to which its closid belonged previously. That is, we can encounter a case like: mkdir newgroup cat newgroup/schemata L2:0=ff;1=ff echo 'L2:0=0xf0;1=0xf0' > newgroup/schemata cat newgroup/schemata L2:0=0xf0;1=0xf0 rmdir newgroup mkdir newnewgroup cat newnewgroup/schemata L2:0=0xf0;1=0xf0 When the new group is created it would be reasonable to expect its allocations to be initialized with all regions that it can possibly use. At this time these regions would be all that are shareable by other resource groups as well as regions that are not currently used. If the available cache region is found to be non-contiguous the available region is adjusted to enforce validity. When a new resource group is created the hardware is initialized with these new default allocations.

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 Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
