2. OS: Ubuntu 22.04.2 LTS
3. gcc: gcc version 11.3.0 (Ubuntu 11.3.0-1ubuntu1~22.04.1)
4. DPDk version: `https://git.dpdk.org/dpdk/tag/?id=v23.07-rc4`
5. DSA Acceleration: `f2:01.0 System peripheral: Intel Corporation Device 0b25`
6. application: `./build/app/dpdk-test-dma-perf`
7. arguments: `-l8-31 --log-level=pmd,8 -a 0000:f2:01.0 --config
app/test-dma-perf/my.ini`
8. driver used: vfio-pci on PF

issue logs:
```
Running scenario 1
Error: Fail to find DMA 0000:f2:01.0.
Not enough dmadevs (0) for all workers (1).
Stopping dmadev 0
dma: Device 0 already stopped.
No proper operation for variable entry.
```

reason for failure: the device name is populated from `idxd_pci.c` as
`0000:f2:01.0-q0`

actions tried:
1. modified by forcing `--proc-type=primary`. same issue 
2. modified name in ini `0000:f2:01.0-q0`, worked.

Checking the driver/dma/idxd_pci.c show cases the issue comes because the
application is identified as `RTE_SECONDARY`. attaching screen shot for the
same.
