--- Comment #15 from commit-h...@freebsd.org --- A commit references this bug: Author: luporl Date: Thu Mar 5 20:04:42 UTC 2020 New revision: 358684 URL: https://svnweb.freebsd.org/changeset/base/358684 Log: [aacraid] Port driver to big-endian Port aacraid driver to big-endian (BE) hosts. The immediate goal of this change is to make it possible to use the aacraid driver on PowerPC64 machines that have Adaptec Series 8 SAS controllers. Adapters supported by this driver expect FIB contents in little-endian (LE) byte order. All FIBs have a fixed header part as well as a data part that depends on the command being issued to the controller. In this way, on BE hosts, the FIB header and all FIB data structures used in aacraid.c and aacraid_cam.c need to be converted to LE before being sent to the adapter and converted to BE when coming from it. The functions to convert each struct are on aacraid_endian.c. For little-endian (LE) targets, they are macros that expand to nothing. In some cases, when only a few fields of a large structure are used, the fields are converted inline, by the code using them.
