This is a counterpart to the HMP "info irq" command. It is being added with an "x-" prefix because this QMP command is intended as an adhoc debugging tool and will thus not be modelled in QAPI as fully structured data, nor will it have long term guaranteed stability. The existing HMP command is rewritten to call the QMP command.
This command is unable to use the pre-existing HumanReadableText, because if 'common.json' is included into 'machine-target.json' the static marshalling method for HumanReadableText will be reported as unused by the compiler on all architectures except s390x. Possible options were 1 Support 'if' conditionals on 'include' statements in QAPI 2 Add further commands to 'machine-target.json' that use HumanReadableText, such that it has at least one usage on all architecture targets. 3 Duplicate HumanReadableText as TargetHumanReadableText adding conditions This patch takes option (3) in the belief that we will eventually get to a point where option (2) happens, and TargetHumanReadableText can be removed again.
