Subject: [dpdk-dev] [PATCH v5 10/20] virtio: Add vtpci_intr_handle() helper to get rte_intr_handle
Date: Fri, 23 Dec 2016 16:58:01 +0100 [thread overview]
Message-ID: <1482508691-11408-11-git-send-email-jblunck@infradead.org> (raw)
In-Reply-To: <1482508691-11408-1-git-send-email-jblunck@infradead.org>
In-Reply-To: <1482332986-7599-1-git-send-email-jblunck@infradead.org>
This adds a helper to get the rte_intr_handle from the virtio_hw. This is
safe to do since the usage of the helper is guarded by RTE_ETH_DEV_INTR_LSC
which is only set if we found a PCI device during initialization.
