The decoder creation for raw trace uses metadata from the first CPU. On per-cpu mode, this metadata is incorrectly used for every decoder. On per-process/per-thread traces, the first CPU is CPU0. If CPU0 trace is not enabled, its metadata will be marked unused and the decoder is not created. Perf report dump skips the decoding part because the decoder is missing. To fix this, use metadata of the CPU associated with sample object.

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.
