Now that filename__read_int() returns -errno instead of -1 these
statements need to be updated otherwise error values will be used as
die IDs.
This appears as a -2 die ID when the platform doesn't export one:
$ perf stat --per-core -a -- true
S36-D-2-C0 1 9.45 msec cpu-clock
And the session topology test fails:
$ perf test -vvv topology
CPU 0, core 0, socket 36
CPU 1, core 1, socket 36
CPU 2, core 2, socket 36
CPU 3, core 3, socket 36
FAILED tests/topology.c:137 Cpu map - Die ID doesn't match
---- end(-1) ----
38: Session topology : FAILED!

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 reStructuredText 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.
