| v0.1.0 |
| ****** |
| |
| - First TF-RMM source release aligned to `RMM Beta0 specification`_. |
| The specified interfaces : Realm Management Interface (RMI) and |
| Realm Service Interface (RSI) are implemented which can attest |
| and run Realm VMs as described by the `Arm CCA`_ Architecture. |
| |
| ================= |
| Upcoming features |
| ================= |
| |
| - Support SVE, Self-Hosted Debug and PMU in Realms |
| - Support LPA2 for Stage 2 Realm translation tables. |
| - Threat model covering RMM data flows. |
| - Enable Bounded Model Checker (CBMC) for source analysis. |

| |
| ============================ |
| Known issues and limitations |
| ============================ |
| |
| The following is a list of issues which are expected to be fixed in the future |
| releases of TF-RMM : |
| |
| - The size of ``RsiHostCall`` structure is 256 bytes in the implementation |
| and aligns to `RMM Beta1 specification`_ rather than the 4 KB size |
| specified in `RMM Beta0 specification`_. |
| |
| - The RSI_IPA_STATE_GET command returns error ``RSI_ERROR_INPUT`` for a |
| `destroyed` IPA instead of emulating data abort to Host. |
| |
| - The `RMM Beta0 specification`_ does not require to have a CBOR bytestream |
| wrapper around the cca-platform-token and cca-realm-delegated-token, but |
| the RMM implementation does so. |
