Tried to use the noe_malloc() method to implement a DMA buffer… however I ran into the same problem as noe_get_device_info() with the function not existing in the compiled library.
/usr/bin/ld: /tmp/ccZ2jwzp.ltrans0.ltrans.o: in function `main':
<artificial>:(.text.startup+0x524): undefined reference to `noe_malloc'
collect2: error: ld returned 1 exit status
$ grep noe_malloc /usr/share/cix/include/npu/cix_noe_standard_api.h
noe_status_t noe_malloc(const context_handler_t* ctx, uint32_t size, void** va, bool dma_buff);
* @brief This API frees a buffer allocated by noe_malloc
The following are the only functions that exist in /usr/share/cix/lib/libnoe.so;

Here is a list of missing functions from the libnoe.so library that are mentioned in the NPU SDK Guide document.
noe_set_job_attr
noe_job_infer_wait
noe_get_tensor_attr_by_?
noe_get_tensor_data_by_?
noe_set_input_tensor_da?
noe_get_job_info
noe_bind_job_core
noe_get_device_info
noe_malloc
noe_free
@DONGHUANG - can we get an updated UMD release to fix these issues please?
