Full documentation for RDC is available at [ROCm DataCenter Tool User Guide](https://rocm.docs.amd.com/projects/rdc/en/latest/).

## RDC 1.4.0 for ROCm 10.1.0
## RDC 1.4.0 for ROCm 10.2.0

### Changed

- **`rdc_health_get()` returns `RDC_ST_GROUP_NOT_FOUND` for a GPU group that does not exist**.
- It returned `RDC_ST_OK` with no health watches, so `rdci health -f` showed every watch as Off and exited successfully, and `rdci health -c` failed asking for watches to be enabled. Both commands now fail with a message that the group does not exist.

### Removed

- Removed the unused `GetBlockNameStr()` test helper and its GPU block name map. Nothing called it, and its `static_assert` on `AMDSMI_GPU_BLOCK_LAST` broke the RDC build whenever AMD SMI added an IP block (#10949).

### Resolved Issues

- `rdci health -s` on a GPU group that does not exist no longer leaves an unused field group in rdcd. Repeated failures filled the field group table, and commands that need a new field group, such as `rdci dmon`, then failed until rdcd was restarted.

- `rdci topo` and `rdc_device_topology_get()` now report the links of the requested GPU. They reported links between other GPU pairs, which showed the wrong link types on systems where GPU pairs are not all linked the same way, such as XGMI hives joined by PCIe.
- `rdci topo` now exits with an error code when the GPU index is out of range or the topology query fails, instead of exiting 0, and `rdc_device_topology_get()` reports link types RDC does not define as `RDC_IOLINK_TYPE_UNDEFINED`.

- `RDC_FI_ECC_CORRECT_TOTAL`, `RDC_FI_ECC_UNCORRECT_TOTAL`, and `RDC_FI_ECC_DEFERRED_TOTAL` no longer hang when AMD SMI defines GPU blocks above bit 31. The block iteration used a 32-bit counter that wrapped to zero instead of terminating.

- Opening or stopping an RDC handle no longer crashes the process when another handle is in use, and concurrent `rdc_connect()` calls no longer fail at random.

- Certificates signed with the RDC certificate authority setup in `authentication/openssl.cnf` can no longer sign other certificates. A certificate request could ask to become a signing certificate, and its holder could then create client and server certificates that `rdcd` and `rdci` trust.

- Stopping `rdcd`, or embedded RDC with `rdc_stop_embedded()`, no longer hangs. Rarely, the stop never returned and the process had to be killed.
