Subject: [dpdk-dev] [PATCH v3 2/4] mempool: add non-IO flag
Date: Tue, 12 Oct 2021 03:04:07 +0300 [thread overview]
Message-ID: <20211012000409.2751908-3-dkozlyuk@nvidia.com> (raw)
In-Reply-To: <20211012000409.2751908-1-dkozlyuk@nvidia.com>
Mempool is a generic allocator that is not necessarily used for device
IO operations and its memory for DMA. Add MEMPOOL_F_NON_IO flag to mark
such mempools.
