"default_core" is used by jevents.py for json events' PMU name when
none is specified. On x86 the "default_core" is typically the PMU
"cpu". When creating an alias see if the event's PMU name is
"default_core" in which case don't record it. This means in places
like "perf list" the PMU's name will be used in its place.
Before:
$ perf list --details
...
cache:
l1d.replacement
[Counts the number of cache lines replaced in L1 data cache]
default_core/event=0x51,period=0x186a3,umask=0x1/
...
After:
$ perf list --details
...
cache:
l1d.replacement
[Counts the number of cache lines replaced in L1 data cache. Unit: cpu]
cpu/event=0x51,period=0x186a3,umask=0x1/
...

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.
