Michael reported an issue with perf bench numa failing with binding to cpu0 with '-0' option. # perf bench numa mem -p 3 -t 1 -P 512 -s 100 -zZcm0 --thp 1 -M 1 -ddd # Running 'numa/mem' benchmark: # Running main, "perf bench numa numa-mem -p 3 -t 1 -P 512 -s 100 -zZcm0 --thp 1 -M 1 -ddd" binding to node 0, mask: 0000000000000001 => -1 perf: bench/numa.c:356: bind_to_memnode: Assertion `!(ret)' failed. Aborted (core dumped) This happens when the cpu0 is not part of node0, which is the benchmark assumption and we can see that's not the case for some powerpc servers. Using correct node for cpu0 binding.

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.
