Hi Suzuki,

As you mentioned in the other response we could add information about
the guest view, something like :
- KVM exposes the sanitised value of the feature registers to the
guests and is not affected by the FTR_VISIBLE. However,
depending on the individual feature support in the hypervisor,
some of the fields may be capped/limited.
Although in most cases, what KVM exposes is indeed a strict subset of
the host's features, there is a few corner cases where we expose
features
that do not necessarily exist on the host. For example ARMv8.5-GTG and
ARMv8.4-TTL get exposed by the NV patches even if they don't exist on
the
host, as KVM will actually emulate them.
Not a big deal, but I just wanted to outline that it isn't as clear-cut
as
it may seem...
Thanks,
M.
