The test_objpool module (test_objpool) will run several testcases for objpool stress and performance evaluation. Each testcase will have all available cpu cores involved to create a situation of high parallel and high contention. As of now there are 5 groups and 5 * 2 testcases in total: 1) group 1: synchronous mode objpool is managed synchronously, that is, all objects are to be reclaimed before objpool finalization and the objpool owner makes sure of it. All threads on different cores run in the same pace 2) group 2: synchronous mode + hrtimer this case have 2 customers: normal threads and hrtimer softirqs 3) group 3: synchronous + overrun mode This test group is mainly for performance evaluation of missing cases when pre-allocated objects are less than the requested 4) group 4: asynchronous mode This case is just an emulation of kretprobe, with refcount used to control the objpool lifecycle 5) group 5: asynchronous mode with hrtimer hrtimer softirq is introduced to stress async objpool operations Link: https://lore.kernel.org/all/20231017135654.82270-3-wuqiang.matt@bytedance.com/ Signed-off-by: wuqiang.matt <wuqiang.matt@bytedance.com> Acked-by: Masami Hiramatsu (Google) <mhiramat@kernel.org> Signed-off-by: Masami Hiramatsu (Google) <mhiramat@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 Restructured Text 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.
