Shared-Memory Extension on s390x

[Kanupriyagoyal]

Team
I am trying to call Shared-Memory Extension REST API's mentioned below on s390x machine.
Would you please elaborate bold note point mentioned below, is it only supported on jetson machine
If not would you please share the examples of how to run, what we mean by region_name in the API calls

https://github.com/triton-inference-server/server/blob/main/docs/protocol/extension_shared_memory.md#shared-memory-extension
Note that there is no Windows support for shared memory yet. Jetson only supports system shared memory.
GET v2/systemsharedmemory[/region/${REGION_NAME}]/status

POST v2/systemsharedmemory/region/${REGION_NAME}/register

POST v2/systemsharedmemory[/region/${REGION_NAME}]/unregister

below examples:
http://localhost:8000/v2/systemsharedmemory/region/IN0/register
{
"key" : "IN0",
"offset" : 0,
"byte_size" : 32
}
response:
{
"error": "Unable to open shared memory region: 'IN0'"
}
