Subject: [dpdk-dev] [PATCH v2] bus/pci: fix wrong intr_handle.type with uio_pci_generic
Date: Fri, 29 Dec 2017 15:55:11 +0800 [thread overview]
Message-ID: <20171229075511.33180-1-zhiyong.yang@intel.com> (raw)
In-Reply-To: <20171228061210.64767-1-zhiyong.yang@intel.com>
For virtio legacy device, testpmd startup fails when using
uio_pci_generic. The issue is caused by invoking the function
pci_ioport_map. The right intr_handle.type is already set before
calling it, we should avoid overwriting the default value "RTE_
INTR_HANDLE_UNKNOWN" in it. Besides, the removal has no harm to
other cases since it already is set to this value (0) at init.
Fixes: 756ce64b1ecd ("eal: introduce PCI ioport API")

2. remove the assignment operation which causes the issue.
