Masami Hiramatsu says: ==================== Hi, Here is the 12th version of fprobe. This version fixes a possible gcc-11 issue which was reported as kretprobes on arm issue, and also I updated the fprobe document. The previous version (v11) is here[1]; [1] https://lore.kernel.org/all/164701432038.268462.3329725152949938527.stgit@devnote2/T/#u This series introduces the fprobe, the function entry/exit probe with multiple probe point support for x86, arm64 and powerpc64le. This also introduces the rethook for hooking function return as same as the kretprobe does. This abstraction will help us to generalize the fgraph tracer, because we can just switch to it from the rethook in fprobe, depending on the kernel configuration. The patch [1/12] is from Jiri's series[2]. [2] https://lore.kernel.org/all/20220104080943.113249-1-jolsa@kernel.org/T/#u And the patch [9/10] adds the FPROBE_FL_KPROBE_SHARED flag for the case if user wants to share the same code (or share a same resource) on the fprobe and the kprobes. I forcibly updated my kprobes/fprobe branch, you can pull this series from: https://git.kernel.org/pub/scm/linux/kernel/git/mhiramat/linux.git kprobes/fprobe Thank you, --- Jiri Olsa (1): ftrace: Add ftrace_set_filter_ips function ==================== Signed-off-by: Alexei Starovoitov <ast@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.
