Subject: [PATCH 8/9] NTB: Add ntb_msi_test support to ntb_test
Date: Thu, 31 Jan 2019 11:56:55 -0700 [thread overview]
Message-ID: <20190131185656.17972-9-logang@deltatee.com> (raw)
In-Reply-To: <20190131185656.17972-1-logang@deltatee.com>
When the ntb_msi_test module is available, the test code will trigger
each of the interrupts and ensure the corresponding occurrences files
gets incremented.
