- Update Skylake events to v50.
- Update Skylake JSON metrics from TMAM 4.0.
- Fix the issue in DRAM_Parallel_Reads
- Fix the perf test warning
Before:
root@kbl-ppc:~# perf stat -M DRAM_Parallel_Reads -- sleep 1
event syntax error: '{arb/event=0x80,umask=0x2/,arb/event=0x80,umask=0x2,thresh=1/}:W'
\___ unknown term 'thresh' for pmu 'uncore_arb'
valid terms: event,edge,inv,umask,cmask,config,config1,config2,name,period,percore
Initial error:
event syntax error: '..umask=0x2/,arb/event=0x80,umask=0x2,thresh=1/}:W'
\___ Cannot find PMU `arb'. Missing kernel support?
root@kbl-ppc:~# perf test metrics
10: PMU events :
10.3: Parsing of PMU event table metrics : Skip (some metrics failed)
10.4: Parsing of PMU event table metrics with fake PMUs: Ok

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.
