Linux kernel source tree
e6b4da6759
A platform can have more than one Arm SPE PMU. For example, a system with multiple clusters may have each cluster enabled with its own Arm SPE instance. In such case, the PMU devices will be named 'arm_spe_0', 'arm_spe_1', and so on. Currently, the tool only supports 'arm_spe_0'. This commit extends support to multiple Arm SPE PMUs by detecting the substring 'arm_spe_'.

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.
