On aarch64 CPU related events are not under event_source/devices/cpu/events,
they're under event_source/devices/armv8_pmuv3_0/events on my machine.
Using current auto-complete script will generate below error:
[root@localhost bin]# perf stat -e
ls: cannot access '/sys/bus/event_source/devices/cpu/events': No such file or directory
Fix this by not testing /sys/bus/event_source/devices/cpu/events on
aarch64 machine.
Fixes: 74cd5815d9 ("perf tool: Improve bash command line auto-complete for multiple events with comma")

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.
