2020-06-16support sError injection in kvm module on Arm64Bin Lu
There are 3 types of asynchronous exceptions on Arm64: sError, IRQ, FIQ. In this case, we use the sError injection method in bluepillHandler to force the guest to quit. So that the test case of "TestBounce" can be passed on Arm64. Signed-off-by: Bin Lu <bin.lu@arm.com>

2020-06-05Add +checkescape annotations to kvm/ring0.Adin Scannell
This analysis also catches a potential bug, which is a split on mapPhysical. This would have led to potential guest-exit during Mapping (although this would have been handled by the now-unecessary retryInGuest loop). PiperOrigin-RevId: 315025106

None of the dependencies have changed in 1.15. It may be possible to simplify some of the wrappers in rawfile following 1.13, but that can come in a later change. PiperOrigin-RevId: 313863264

2020-05-17adding the VM-Exit method for Arm64Bin Lu
On amd64, it uses 'HLT' to leave the guest. Unlike amd64, arm64 can only uses mmio_exit/psci to leave the guest. So, I designed the HYPERCALL_VMEXIT to be compatible with amd64/arm64. To keep it simple, I used the address of exception table as the MMIO base address, so that I can trigger a MMIO-EXIT by forcibly writing this space. Then, in host user space, I can calculate this address to find out which hypercall. Signed-off-by: Bin Lu <bin.lu@arm.com>
