We have two types of RX RQs, and they use two separate sets of info arrays and structures in RX data path function. Today those structures are mutually exclusive per RQ type, hence one kind is allocat

Before this patch LRO size was 64K, now with build_skb requires extra room, headroom + sizeof(skb_shared_info) added to the data buffer will make wqe size or page_frag_size slightly larger than 64K wh

Add two helper functions to allow dynamic changes of RQ type. mlx5e_set_rq_priv_params and mlx5e_set_rq_type_params will be used on netdev creation to determine the default RQ type. This will be neede

Make a clear separate between Regular SQ (TXQ) and ICO SQ creation, destruction and union their mutual information structures. Don't allocate redundant TXQ skb/wqe_info/dma_fifo arrays for ICO SQ. And

Adding support for XDP_TX forwarding from xdp program. Using XDP, now user can loop packets out of the same port. We create a dedicated TX SQ for each channel that will serve XDP programs that return

Previously we rang XDP SQ doorbell on every forwarded XDP packet. Here we introduce a xmit more like mechanism that will queue up more than one packet into SQ (up to RX napi budget) w/o notifying the

Hi All, Thanks for joining the call today, below you may find my notes. Upcoming conference info: netdev - Japan - early October Alexei, Daniel B, Jesper voiced their ack that they would attend Plumbe

Yes, I will make this more clear in the actual submission, Here we are talking about different RSS core rings. Here we did, the first row is what you are describing the other rows are the same test wi

Hi Saeed, How many cores are you using with these numbers? Just a single core? Or are streams being RSS'd across cores somehow. Thanks, John

Hi All, This patch set introduces some important data path RX refactoring addressing mlx5e memory allocation/management improvements and XDP support. Submitting as RFC since we would like to get an ea

Hi All, I am interested in learning and contributing to the Iovisor project. What would be good way to get started ? I saw that there several open issues in https://github.com/iovisor. Perhaps, take s

From: Tariq Toukan <tariqt@...> Instead of reallocating and mapping pages for RX data-path, recycle already used pages in a per ring cache. We ran pktgen single-stream benchmarks, with iptables-raw-dr

I'm sorry but I have a problem with this patch! Looking at this patch, I want to bring up a fundamental architectural concern with the development direction of XDP transmit. What you are trying to imp

From: Rana Shahout <ranas@...> Add support for the BPF_PROG_TYPE_PHYS_DEV hook in mlx5e driver. When XDP is on we make sure to change channels RQs type to MLX5_WQ_TYPE_LINKED_LIST rather than "stridin

From: Tariq Toukan <tariqt@...> To improve the memory consumption scheme, we omit the flow that demands and splits high-order pages in Striding RQ, and stay with a single Striding RQ flow that uses or

Hi Brenden, I don't quite understand the semantics of the XDP userspace interface. We allow XDP programs to be (unconditionally) exchanged by another program, this avoids taking the link down+up and a

For non-striding RQ configuration before this patch we had a ring with pre-allocated SKBs and mapped the SKB->data buffers for device. For robustness and better RX data buffers management, we allocate

Hi Brenden, I don't quite understand the semantics of the XDP userspace interface. We allow XDP programs to be (unconditionally) exchanged by another program, this avoids taking the link down+up and a

Hi all, As promised, I've started documenting the XDP eXpress Data Path): [1] https://prototype-kernel.readthedocs.io/en/latest/networking/XDP/index.html IMHO the documentation have reached a stage wh

Hello All, I am a student majored in Computer Science from Korea. I want to be contributor in IO Visor project, so I'm reading all docs and source code in IO Visor webpage & Github. While I read 'Cont
