Hello,
it would be really nice to get the CP15 VBAR support integrated. This allows
unit test suites of single address space real-time systems to catch NULL
pointer read/write access for example.
The ARM documentation says that this is a banked register that is only present
in an implementation that includes the Security Extensions. Is this equivalent
to having TrustZone?
In the ID_PFR1, Processor Feature Register 1, the bits [4:7] indicate if a
particular CPU has this feature. Is it possible to use this register to
determine the availability of the VBAR register in Qemu? This may avoid adding
a new enum arm_features.
