Tariq Toukan says: ==================== net/mlx5e: SHAMPO, Enable HW GRO once more This series enables hardware GRO for ConnectX-7 and newer NICs. SHAMPO stands for Split Header And Merge Payload Offload. The first part of the series contains important fixes and improvements. The second part reworks the HW GRO counters. Lastly, HW GRO is perf optimized and enabled. Here are the bandwidth numbers for a simple iperf3 test over a single rq where the application and irq are pinned to the same CPU: +---------+--------+--------+-----------+-------------+ | streams | SW GRO | HW GRO | Unit | Improvement | +---------+--------+--------+-----------+-------------+ | 1 | 36 | 57 | Gbits/sec | 1.6 x | | 4 | 34 | 50 | Gbits/sec | 1.5 x | | 8 | 31 | 43 | Gbits/sec | 1.4 x | +---------+--------+--------+-----------+-------------+ Benchmark details: VM based setup CPU: Intel(R) Xeon(R) Platinum 8380 CPU, 24 cores NIC: ConnectX-7 100GbE iperf3 and irq running on same CPU over a single receive queue ==================== Link: https://lore.kernel.org/r/20240603212219.1037656-1-tariqt@nvidia.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
