It is the time we have the real 16-bit Stream ID user, which is the ThunderX. Its IO topology uses 1:1 map for Requester ID to Stream ID translation for each root complex which allows to get full 16-bit Stream ID. Firmware assigns bus IDs that are greater than 128 (0x80) to some buses under PEM (external PCIe interface). Eventually SMMU drops devices on that buses because their Stream ID is out of range: pci 0006:90:00.0: stream ID 0x9000 out of range for SMMU (0x7fff) To fix above issue enable the Extended Stream ID optional feature when available.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
