C++ (Cpp) vm_inject_exception Examples

Example #1

File: vmm_api.c Project: 0x414A/docker-machine-driver-xhyve

int
xh_vm_inject_exception(int vcpu, int vector, int errcode_valid,
	uint32_t errcode, int restart_instruction)
{
	int error;

	vcpu_freeze(vcpu, true);
	error = vm_inject_exception(vm, vcpu, vector, errcode_valid, errcode,
		restart_instruction);
	vcpu_freeze(vcpu, false);

	return (error);
}

Example #2

File: vmm.c Project: RnbWd/hyperkit

void
vm_inject_fault(void *vmarg, int vcpuid, int vector, int errcode_valid,
    int errcode)
{
	struct vm *vm;
	int error, restart_instruction;

	vm = vmarg;
	restart_instruction = 1;

	error = vm_inject_exception(vm, vcpuid, vector, errcode_valid,
	    ((uint32_t) errcode), restart_instruction);
	KASSERT(error == 0, ("vm_inject_exception error %d", error));
}

Example #3

File: bhyverun.c Project: moscaliucpaulandrei/freebsd

void
vm_inject_fault(void *arg, int vcpu, int vector, int errcode_valid,
    int errcode)
{
	struct vmctx *ctx;
	int error, restart_instruction;

	ctx = arg;
	restart_instruction = 1;

	error = vm_inject_exception(ctx, vcpu, vector, errcode_valid, errcode,
	    restart_instruction);
	assert(error == 0);
}

Example #4

File: vmm.c Project: vinceguogit/freebsd

static void
vm_inject_fault(struct vm *vm, int vcpuid, struct vm_exception *exception)
{
	struct vm_exit *vmexit;
	int error;

	error = vm_inject_exception(vm, vcpuid, exception);
	KASSERT(error == 0, ("vm_inject_exception error %d", error));

	/*
	 * A fault-like exception allows the instruction to be restarted
	 * after the exception handler returns.
	 *
	 * By setting the inst_length to 0 we ensure that the instruction
	 * pointer remains at the faulting instruction.
	 */
	vmexit = vm_exitinfo(vm, vcpuid);
	vmexit->inst_length = 0;
