Hi, I am now using DLA on jetson xavier nx to do DNN inference. I would like to create multiple contexts(i.e. load multiple engines) for a DLA. However I have found that I can only create 3 or 4(depend on engine size) and then it reports error. I am using jetpack4.6.
NvMapMemAllocInternalTagged: 1074810371 error 12
NvMapMemHandleAlloc: error 12
Module_id 33 Severity 2 : NVMEDIA_DLA 2650
Module_id 33 Severity 2 : Runtime: loadBare failed. error: 0x000006
ERROR: 1: [nvdlaUtils.cpp::deserialize::164] Error Code 1: DLA (NvMediaDlaLoadLoadable : load loadable failed.)
I have found similar issues in the following links:

How to know when to stop generating new DLA context? - #7 by yjkim2
It seems that the DLA can only support 4 contexts since jetpack 4.3. But jetpack 4.3 allows create up to 8 contexts.
So I wonder any latter jetpack versions fixed this issue? If not, is AGX Xavier or AGX Orin support more than 4 DLA contexts ?
Thank you very much for answering this long question!
