Abstract
Embodiments include method, systems and computer program products for resource management of untrusted programs. In some embodiments, a first request to process an asynchronous event by an untrusted application may be received. The first request may include a host memory address. A counter may be incremented in response to receiving the first request. A device memory address may be retrieved from a device translation table using the host memory address. Processing the first request by a device using the device memory address may be facilitated. A second request to unregister the host memory address may be received. The counter may be determined to be non-zero. An action may be implemented in response to determining that the counter is non-zero.
