Abstract
Various embodiments are generally directed to instrumenting an interrupt service routine. A non-executable address may be provisioned and added to an execution stack to cause a page fault on a known address after execution of an interrupt service routine. The page fault on the known address can be used to trigger instrumentation operations and also to return to the interrupted process.
