DOE mailbox objects will be needed for various mailbox communications with each memory device. Iterate each DOE mailbox capability and create PCI DOE mailbox objects as found. It is not anticipated that this is the final resting place for the iteration of the DOE devices. The support of switch ports will drive this code into the PCIe side. In this imagined architecture the CXL port driver would then query into the PCI device for the DOE mailbox array. For now creating the mailboxes in the CXL port is good enough for the endpoints. Later PCIe ports will need to support this to support switch ports more generically.

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.
