The jevent "Unit" field is used for uncore PMU alias definition. The form uncore_pmu_example_X is supported, where "X" is a wildcard, to support multiple instances of the same PMU in a system. Unfortunately this format not suitable for all uncore PMUs; take the Hisi DDRC uncore PMU for example, where the name is in the form hisi_scclX_ddrcY. For for current jevent parsing, we would be required to hardcode an uncore alias translation for each possible value of X. This is not scalable. Instead, add support for "Unit" field in the form "hisi_sccl,ddrc", where we can match by hisi_scclX and ddrcY. Tokens in Unit field are delimited by ','.

README
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.
