HW path does not work with job_api_example

[gaowayne]

I change job_api_example to HW path

int main(const int argc, char *const argv) { // Variables dml_job_t dml_job_ptr = NULL; uint32_t total_fails = 0u;

// Allocate dml_job_t
dml_job_ptr = init_dml_job(DML_PATH_SW);

change this into DML_PATH_HW, then I just got a lot of error and fail without any log to show me root cause or suggest next action.

please notice I have good kernel DSA driver configure, I can run SPDK kernel path DRAM to DRAM copy done well.

Hi @gaowayne, 100 error code is DML_STATUS_LIBACCEL_NOT_FOUND, this most probably mean that you don't have libaccel-config.so.1 installed on your system. Please, double check if it is available in usr/lib64.

Hi @gaowayne please, let me know if you still see the issue or if this could be closed.

Hi @gaowayne please, let me know if you still see the issue or if this could be closed.

sorry man, I lost the DSA HW environment, I cannot verify this now.

[mzhukova]

Closing the issue as it can't be reproduced anymore.
