Subject: Re: [PATCH] net/mlx5: allocate dma pool structs on the pool's NUMA node
Date: Mon, 05 Oct 2026 13:53:23 +0000 [thread overview]
Message-ID: <20261005135324.45CE81F000FF@smtp.kernel.org> (raw)
In-Reply-To: <20261005-net-mlx5-numa-allocate-pool-page-v1-1-01f4283932b4@snu.ac.kr>
> The mlx5 DMA pool structs (mlx5_dma_pool, mlx5_dma_pool_page and its
> block bitmap, and mlx5_frag_buf_node_pools) are allocated without a
> node hint, so they land on the node of whichever CPU happens to create
> or fill the pool, whiile the DMA pages they describe are allocated on

>
> The pool, page and bitmap are dereferenced on every block allocation
