H A D | mbox.c | 92fcc1ab Sun Apr 03 21:12:15 CDT 2022 Davidlohr Bueso <dave@stgolabs.net> cxl/mbox: Improve handling of mbox_cmd hw return codes
Upon a completed command the caller is still expected to check the actual return_code register to ensure it succeed. This adds, per the spec, the potential command return codes. It maps the hardware return code with the kernel's errno style, and by default continues to use -ENXIO (Command completed, but device reported an error).
