Brett Creeley says: ==================== ionic: convert Rx queue buffers to use page_pool Our home-grown buffer management needs to go away and we need to play nicely with the page_pool infrastructure. This patchset cleans up some of our API use and converts the Rx traffic queues to use page_pool. The first few patches are for tidying up things, then a small XDP configuration refactor, adding page_pool support, and finally adding support to hot swap an XDP program without having to reconfigure anything. The result is code that more closely follows current patterns, as well as a either a performance boost or equivalent performance as seen with iperf testing: mss netio tx_pps rx_pps total_pps tx_bw rx_bw total_bw ---- ------- ---------- ---------- ----------- ------- ------- ---------- Before: 256 bidir 13,839,293 15,515,227 29,354,520 34 38 71 512 bidir 13,913,249 14,671,693 28,584,942 62 65 127 1024 bidir 13,006,189 13,695,413 26,701,602 109 115 224 1448 bidir 12,489,905 12,791,734 25,281,639 145 149 294 2048 bidir 9,195,622 9,247,649 18,443,271 148 149 297 4096 bidir 5,149,716 5,247,917 10,397,633 160 163 323 8192 bidir 3,029,993 3,008,882 6,038,875 179 179 358 9000 bidir 2,789,358 2,800,744 5,590,102 181 180 361 After: 256 bidir 21,540,037 21,344,644 42,884,681 52 52 104 512 bidir 23,170,014 19,207,260 42,377,274 103 85 188 1024 bidir 17,934,280 17,819,247 35,753,527 150 149 299 1448 bidir 15,242,515 14,907,030 30,149,545 167 174 341 2048 bidir 10,692,542 10,663,023 21,355,565 177 176 353 4096 bidir 6,024,977 6,083,580 12,108,557 187 180 367 8192 bidir 3,090,449 3,048,266 6,138,715 180 176 356 9000 bidir 2,859,146 2,864,226 5,723,372 178 180 358 v2: https://lore.kernel.org/20240826184422.21895-1-brett.creeley@amd.com v1: https://lore.kernel.org/20240625165658.34598-1-shannon.nelson@amd.com ==================== Link: https://patch.msgid.link/20240906232623.39651-1-brett.creeley@amd.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.
