Subject: [PATCH 4/7] tools: PCI: Add 'e' to clear IRQ
Date: Mon, 30 Dec 2019 18:03:12 +0530 [thread overview]
Message-ID: <20191230123315.31037-5-kishon@ti.com> (raw)
In-Reply-To: <20191230123315.31037-1-kishon@ti.com>
Add a new command line option 'e' to invoke "PCITEST_CLEAR_IRQ"
ioctl. This can be used to clear the irqs set using the 'i' option.
