Jakub Kicinski says: ==================== This set is focused on improving the performance of perf events reported from BPF offload. Perf events can now be received on packet data queues, which significantly improves the performance (from total of 0.5 Msps to 5Msps per core). To get to this performance we need a fast path for control messages which will operate on raw buffers and recycle them immediately. Patch 5 replaces the map pointers for perf maps with map IDs. We look the pointers up in a hashtable, anyway, to validate they are correct, so there is no performance difference. Map IDs have the advantage of being easier to understand for users in case of errors (we no longer print raw pointers to the logs). Last patch improves info messages about map offload. ==================== Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> |

README
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 Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
