Yonghong Song says: ==================== Previous maximum supported integer bit width is 64. But the __int128 type has been supported by most (if not all) 64bit architectures including bpf for both gcc and clang. The kernel itself uses __int128 for x64 and arm64. Some bcc tools are using __int128 in bpf programs to describe ipv6 addresses. Without 128bit int support, the vmlinux BTF won't work and those bpf programs using __int128 cannot utilize BTF. This patch set therefore implements BTF __int128 support. ==================== Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>
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.
