Alexander Lobakin says: ==================== xdp: a fistful of generic changes pt. I XDP for idpf is currently 6 chapters: * convert Rx to libeth; * convert Tx and stats to libeth; * generic XDP and XSk code changes (you are here); * generic XDP and XSk code additions; * actual XDP for idpf via new libeth_xdp; * XSk for idpf (via ^). Part III does the following: * improve &xdp_buff_xsk cacheline placement; * does some cleanups with marking read-only bpf_prog and xdp_buff arguments const for some generic functions; * allows attaching already registered XDP memory model to RxQ info; * makes system percpu page_pools valid XDP memory models; * starts using netmems in the XDP core code (1 function); * allows mixing pages from several page_pools within one XDP frame; * optimizes &xdp_frame layout and removes no-more-used field. Bullets 4-6 are the most important ones. All of them are prereqs to libeth_xdp. ==================== Link: https://patch.msgid.link/20241203173733.3181246-1-aleksander.lobakin@intel.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.
