SELFOUR-555: Rename ksCurCPU->armHSCurVCPU
SELFOUR-557: s/isIOSpaceFrame/isIOSpaceFrameCap/
Other changes in pull request have no effect on current Haskell spec.
Hypervisor extensions add extra fault types which are entirely
arch-specific. While the concept of a VM fault exists on all platforms,
these faults are also arch-specific.
This change adds an ArchFault datatype and constructor to the generic
Faults and Failures, and moves VMFault into ArchFault for the ARM
platform.
NOTE: fault indices have changed (generic goes before arch) as per
the changes needed for SELFOUR-413, which is the seL4 C equivalent of
this commit.
- dropped InvokePageIO in favour of capVPisIOSpace flag on PageCap
- converted some objBits (undefined :: ...) to pteBits and pdeBits
- added invalid IOPDEs and IOPTEs encoded to 0
- added IOPTEs and IOPDEs to PSpaceStorable
- adjusted asidHighBits to drop one on enabling MMU
The kernel gains an entry point for hypervisor exception events, as well
as a way to add arch-specific handlers for these events.
We do this since the hypervisor has its own entry point into the kernel,
and that must be reflected in the top-level kernel entry interface.
For ARM target, which does not have hypervisor support, we add an no-op stub.
Other platforms such as arm-hyp will need to look into additional TCB state
such as VCPU in sanitiseRegister. This commit provides the scaffolding for
that.
- replace ARM-specific constants and types with aliases which can be
instantiated separately for each architecture.
- expand lib with lemmas used in X64 proofs.
- simplify some proofs.
