Andi Kleen bd1040e646 perf vendor events intel: Fix Load_Miss_Real_Latency on SKL/SKX
[ Upstream commit 91b2b97025 ]

Fix incorrect event names for the Load_Miss_Real_Latency metric for
Skylake and Skylake Server.

Fixes https://github.com/andikleen/pmu-tools/issues/158

Before:

  % perf stat -M Load_Miss_Real_Latency true
  event syntax error: '..ss.pending,mem_load_retired.l1_miss_ps,mem_load_retired.fb_hit_ps}:W'
                                    \___ parser error

   Usage: perf stat [<options>] [<command>]

      -M, --metrics <metric/metric group list>
                            monitor specified metrics or metric groups (separated by ,)

After:

  % perf stat -M Load_Miss_Real_Latency true

   Performance counter stats for 'true':

             279,204      l1d_pend_miss.pending     #     14.0 Load_Miss_Real_Latency
               4,784      mem_load_uops_retired.l1_miss
              15,188      mem_load_uops_retired.hit_lfb

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.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
