What is the "SOE"

[thundergolfer]

I've Googled and asked Claude about this but haven't gotten a satisfying answer. The SOE abbreviation is all over the codebase and specifically in these SXID codes:

NVSWITCH_ERR_HW_SOE                                                = 26000,
NVSWITCH_ERR_HW_SOE_RESET                                          = 26001,
NVSWITCH_ERR_HW_SOE_BOOTSTRAP                                      = 26002,
NVSWITCH_ERR_HW_SOE_COMMAND_QUEUE                                  = 26003,
NVSWITCH_ERR_HW_SOE_TIMEOUT                                        = 26004,
NVSWITCH_ERR_HW_SOE_SHUTDOWN                                       = 26005,
NVSWITCH_ERR_HW_SOE_HALT                                           = 26006,
NVSWITCH_ERR_HW_SOE_EXTERR                                         = 26007,
NVSWITCH_ERR_HW_SOE_WATCHDOG                                       = 26008,

I'd like to understand which of these is a critical error.

I believe it stands for "secure offload engine".

Thanks!

Is there any documentation on how to triage these error codes for the Secure Offload Engine?

[aritger]

Not that I'm aware of; sorry.

Guess we'll have to learn from experience. Thanks.
