# O-RAN AAL DPDK EAL parameters
To configure O-RAN AAL/DPDK BBDEV, you can set the following parameters via the command line of PHY simulators or nr-softmodem:
- `nrLDPC_coding_t2.dpdk_dev` - **mandatory** parameter, specifies the PCI address of our accelerator. It must follow the format `WWWW:XX:YY.Z`.
> Note: the group parameter name has been renamed from `nrLDPC_coding_t2` to
> `nrLDPC_coding_aal` to better reflect that it is a generic AAL accelerator
> card.
- `nrLDPC_coding_t2.dpdk_core_list` - **mandatory** parameter, specifies the CPU cores assigned to DPDK .
Ensure that the CPU cores specified in `nrLDPC_coding_t2.dpdk_core_list` are available and not used by other processes to avoid conflicts.
- `nrLDPC_coding_aal.dpdk_dev` - **mandatory** parameter, specifies the PCI address of our accelerator. It must follow the format `WWWW:XX:YY.Z`.
- `nrLDPC_coding_t2.dpdk_prefix` - optional parameter, DPDK shared data file prefix, by default set to *b6*.
- `nrLDPC_coding_aal.dpdk_core_list` - **mandatory** parameter, specifies the CPU cores assigned to DPDK .
Ensure that the CPU cores specified in `nrLDPC_coding_aal.dpdk_core_list` are available and not used by other processes to avoid conflicts.
- `nrLDPC_coding_t2.vfio_vf_token` - optional parameter, VFIO token set for the VF, if applicable.
- `nrLDPC_coding_aal.dpdk_prefix` - optional parameter, DPDK shared data file prefix, by default set to *b6*.
- `nrLDPC_coding_t2.num_harq_codeblock` - optional parameter, size of the HARQ buffer in terms of the number of 32kB blocks, by default set to *512* (maximum for the T2; as for the ACCs, this can be further increased).
- `nrLDPC_coding_aal.vfio_vf_token` - optional parameter, VFIO token set for the VF, if applicable.
- `nrLDPC_coding_t2.eal_init_bbdev` - optional parameter, set this to 1 when using with FHI72 with the Intel ACCs. For the T2, this is not required.
- `nrLDPC_coding_aal.num_harq_codeblock` - optional parameter, size of the HARQ buffer in terms of the number of 32kB blocks, by default set to *512* (maximum for the T2; as for the ACCs, this can be further increased).
- `nrLDPC_coding_aal.eal_init_bbdev` - optional parameter, set this to 1 when using with FHI72 with the Intel ACCs. For the T2, this is not required.
**Note:** These parameters can also be provided in a configuration file.

# Known Issue(s)
## BBDEV CPU Usage
When running the E2E setup (this applies to both USRP and FHI72), BBDEV may not be using the list of CPU cores as specified by `nrLDPC_coding_t2.dpdk_core_list` accordingly.
When running the E2E setup (this applies to both USRP and FHI72), BBDEV may not be using the list of CPU cores as specified by `nrLDPC_coding_aal.dpdk_core_list` accordingly.
This is an issue under investigation, and subject for future fixes.
In the meantime, we recommend allocating idle, and isolated CPU cores in the configuration for BBDEV.
