Abstract
A method, system, and computer-usable medium for supporting debugging of host channel adapters in a logical partitioning environment. In a preferred embodiment of the present invention, a hypervisor acquires control of a trace facility and sets trace parameters for the host channel adapter. In response to determining a trace event that matches said trace parameter has been triggered, the hypervisor retrieves trace information from a buffer. In response to determining the buffer does not include any more trace information, the hypervisor determines if modification of the trace parameters is required. If the modification of the trace parameters is required, the hypervisor alters the trace parameters in anticipation of another trace event.
