Enum HyperlightExit

pub enum HyperlightExit {
    Halt(),
    IoOut(u16, Vec<u8>, u64, u64),
    Mmio(u64),
    AccessViolation(u64, MemoryRegionFlags, MemoryRegionFlags),
    Cancelled(),
    Unknown(String),
    Retry(),
}

These are the generic exit reasons that we can handle from a Hypervisor the Hypervisors run method is responsible for mapping from the hypervisor specific exit reasons to these generic ones

Variants

Halt()

The vCPU has halted

IoOut(u16, Vec<u8>, u64, u64)

The vCPU has issued a write to the given port with the given value

Mmio(u64)

The vCPU has attempted to read or write from an unmapped address

AccessViolation(u64, MemoryRegionFlags, MemoryRegionFlags)

The vCPU tried to access memory but was missing the required permissions

Cancelled()

The vCPU execution has been cancelled

Unknown(String)

The vCPU has exited for a reason that is not handled by Hyperlight

Retry()

The operation should be retried, for example this can happen on Linux where a call to run the CPU can return EAGAIN
