| 12 | - This release has been verified with `TF-A v2.8`_ release. |
| 13 | |
| 14 | - The release has the following fixes and enhancements: |
| 15 | |
| 16 | * Add support to render documentation on read-the-docs. |
| 17 | * Fix the known issue with RSI_IPA_STATE_GET returning |
| 18 | ``RSI_ERROR_INPUT`` for a `destroyed` IPA instead of |
| 19 | emulating data abort to NS Host. |
| 20 | * Fix an issue with RSI_HOST_CALL not returning back to Host |
| 21 | to emulate a stage2 data abort. |
| 22 | * Harden an assertion check for ``do_host_call()``. |
| 23 | |
| 24 | - The other known issues and limitations remain the same as |
| 25 | listed for v0.1.0_. |

| 31 | ****** |
| 32 | |
| 33 | - First TF-RMM source release aligned to `RMM Beta0 specification`_. |
| 34 | The specified interfaces : Realm Management Interface (RMI) and |
| 35 | Realm Service Interface (RSI) are implemented which can attest |
| 36 | and run Realm VMs as described by the `Arm CCA`_ Architecture. |
| 37 | |
| 38 | ================= |
| 39 | Upcoming features |
| 40 | ================= |
| 41 | |
| 42 | - Support SVE, Self-Hosted Debug and PMU in Realms |
| 43 | - Support LPA2 for Stage 2 Realm translation tables. |
| 44 | - Threat model covering RMM data flows. |
| 45 | - Enable Bounded Model Checker (CBMC) for source analysis. |
| 46 | - Unit test framework based on :ref:`RMM Fake host architecture`. |
| 47 | |
| 48 | ============================ |
| 49 | Known issues and limitations |
| 50 | ============================ |
| 51 | |
| 52 | The following is a list of issues which are expected to be fixed in the future |
| 53 | releases of TF-RMM : |
| 54 | |
| 55 | - The size of ``RsiHostCall`` structure is 256 bytes in the implementation |
| 56 | and aligns to `RMM Beta1 specification`_ rather than the 4 KB size |
| 57 | specified in `RMM Beta0 specification`_. |
| 58 | |
| 59 | - The RSI_IPA_STATE_GET command returns error ``RSI_ERROR_INPUT`` for a |
| 60 | `destroyed` IPA instead of emulating data abort to Host. |
| 61 | |
| 62 | - The `RMM Beta0 specification`_ does not require to have a CBOR bytestream |
| 63 | wrapper around the cca-platform-token and cca-realm-delegated-token, but |
| 64 | the RMM implementation does so. |
