Subject: [kvm-unit-tests PATCH v2 3/9] s390x: irq: make IRQ handler weak
Date: Thu, 28 Nov 2019 13:46:01 +0100 [thread overview]
Message-ID: <1574945167-29677-4-git-send-email-pmorel@linux.ibm.com> (raw)
In-Reply-To: <1574945167-29677-1-git-send-email-pmorel@linux.ibm.com>
Having a weak function allows the tests programm to declare its own
IRQ handler.
This is helpfull for I/O tests to have the I/O IRQ handler having
its special work to do.
