Subject: [dpdk-dev] [PATCH v3] eal: read data buffer on RTE_INTR_HANDLE_VFIO_REQ
Date: Tue, 24 Aug 2021 11:26:45 +0200	[thread overview]
Message-ID: <20210824092645.729881-1-maciej.szwed@intel.com> (raw)
In-Reply-To: <BL0PR11MB29484DF93707E906EDFABEAD97C49@BL0PR11MB2948.namprd11.prod.outlook.com>

We should call read() on RTE_INTR_HANDLE_VFIO_REQ event
to confirm that event.
