Hi all,

We are introducing support for FEAT_LPA2 into TF-RMM (patches are available here). Once the patches are merged, FEAT_LPA2 will be a mandatory feature for TF-RMM to work. This means that FVP will need to enable this feature when running. To do so, the following changes are needed on the command line:

- -C cluster0.PA_SIZE=48
+
 -C cluster0.PA_SIZE=52
+ -C cluster0.has_large_va=2
+ -c cluster0.has_52bit_address_with_4k=2

This needs to be applied to all the clusters on the model.

In addition to that, "arch_version" on the model needs to be set to "8.7" or higher.

The changes can be applied at any point from now as at the moment TF-RMM is able to work with and without FEAT_LPA2. Once the patches are merged, though, TF-RMM will fail during boot if FEAT_LPA2 is not available.

Thank you very much.

Best regards,

Javier
