1Fixed Virtual Platform (FVP) Support 2------------------------------------ 3 4An |FVP| provides a complete simulation of an Arm system. This is a generic term 5used for all kinds of vastly different and incompatible systems. One category of 6these systems are the ``FVP_Base`` family of FVPs. These are entirely virtual 7platforms, largely used for early feature development. They offer a large 8degrees of customisation but share a lot of similarities. The ``fvp`` platform 9in TF-A supports these platforms only. Despite the generic name, other FVPs (eg 10FVP_TC4) have their own dedicated TF-A platforms and will not work with this one. 11 12Please refer to each FVP's documentation for a detailed description of the model 13parameter options. 14 15The latest version of the AArch64 build of TF-A has been tested on the following 16Arm FVPs without shifted affinities, and that do not support threaded CPU cores 17(64-bit host machine only). 18 19.. note:: 20 The FVP models used are version 11.28 Build 23. 21 22- ``FVP_Base_AEMvA-AEMvA`` 23- ``FVP_Base_RevC-2xAEMvA`` 24- ``FVP_Base_Cortex-A32`` 25- ``FVP_Base_Cortex-A35`` 26- ``FVP_Base_Cortex-A53`` 27- ``FVP_Base_Cortex-A55`` 28- ``FVP_Base_Cortex-A57x1-A53x1`` 29- ``FVP_Base_Cortex-A57x2-A53x4`` 30- ``FVP_Base_Cortex-A57`` 31- ``FVP_Base_Cortex-A57x4-A53x4`` 32- ``FVP_Base_Cortex-A65`` 33- ``FVP_Base_Cortex-A65AE`` 34- ``FVP_Base_Cortex-A72`` 35- ``FVP_Base_Cortex-A73`` 36- ``FVP_Base_Cortex-A73x4-A53x4`` 37- ``FVP_Base_Cortex-A75`` 38- ``FVP_Base_Cortex-A76`` 39- ``FVP_Base_Cortex-A76AE`` 40- ``FVP_Base_Cortex-A77`` 41- ``FVP_Base_Cortex-A78`` 42- ``FVP_Base_Cortex-A78AE`` 43- ``FVP_Base_Cortex-A78C`` 44- ``FVP_Base_Cortex-A710`` 45- ``FVP_Base_Cortex-X2`` 46- ``FVP_Base_Cortex-X4`` 47- ``FVP_Base_Cortex-X925`` 48- ``FVP_Base_Neoverse-E1`` 49- ``FVP_Base_Neoverse-N1`` 50- ``FVP_Base_Neoverse-N2`` 51- ``FVP_Base_Neoverse-V1`` 52 53The latest version of the AArch32 build of TF-A has been tested on the 54following Arm FVPs without shifted affinities, and that do not support threaded 55CPU cores (64-bit host machine only). 56 57- ``FVP_Base_AEMvA`` 58- ``FVP_Base_AEMvA-AEMvA`` 59- ``FVP_Base_Cortex-A32`` 60 61.. note:: 62 The ``FVP_Base_RevC-2xAEMv8A`` FVP only supports shifted affinities, which 63 is not compatible with legacy GIC configurations. Therefore this FVP does not 64 support these legacy GIC configurations. 65 66The *Foundation* and *Base* FVPs can be downloaded free of charge. See the 67`Arm's website`_ for download options of all FVPs. 68 69.. note:: 70 The build numbers quoted above are those reported by launching the FVP 71 with the ``--version`` parameter. 72 73.. note:: 74 Linaro provides a ramdisk image in prebuilt FVP configurations and full 75 file systems that can be downloaded separately. To run an FVP with a virtio 76 file system image an additional FVP configuration option 77 ``-C bp.virtioblockdevice.image_path="<path-to>/<file-system-image>`` can be 78 used. 79 80.. note:: 81 The software will not work on Version 1.0 of the Foundation FVP. 82 The commands below would report an ``unhandled argument`` error in this case. 83 84.. note:: 85 FVPs can be launched with ``--cadi-server`` option such that a 86 CADI-compliant debugger (for example, Arm DS-5) can connect to and control 87 its execution. 88 89.. warning:: 90 Since FVP model Version 11.0 Build 11.0.34 and Version 8.5 Build 0.8.5202 91 the internal synchronisation timings changed compared to older versions of 92 the models. The models can be launched with ``-Q 100`` option if they are 93 required to match the run time characteristics of the older versions. 94 95All the above platforms have been tested with `Linaro Release 20.01`_. 96 97-------------- 98 99*Copyright (c) 2019-2025, Arm Limited.
