The difference between access class 0 and access class 1 for 'struct access_coordinate', if any, is that class 0 is for the distance from the target to the closest initiator and that class 1 is for the distance from the target to the closest CPU. For CXL memory, the nearest initiator may not necessarily be a CPU node. The performance path from the CXL endpoint to the host bridge should remain the same. However, the numbers extracted and stored from HMAT is the difference for the two access classes. Split out the performance numbers for the host bridge (generic target) from the calculation of the entire path in order to allow calculation of both access classes for a CXL region.

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. 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.
