From 917dfab881becfad104ad02682a88afb54284932 Mon Sep 17 00:00:00 2001
From: Andi Kleen <ak@linux.intel.com>
Date: Wed, 1 Jul 2015 14:36:42 -0700
Subject: [PATCH 1/3] Add support for Intel Skylake events
Add support for the Intel Skylake micro architecture to oprofile.
OFFCORE_* and FRONTEND_* events are not supported for now because
oprofile does not support setting up config1

From ccc38adf33e3ae845e0b7c4f8fe77beceaa7b930 Mon Sep 17 00:00:00 2001
From: Andi Kleen <ak@linux.intel.com>
Date: Mon, 6 Jul 2015 16:48:25 -0700
Subject: [PATCH 2/3] oprofile: Fixes for Skylake event lists
This fixes the review feedback for the Skylake event list.
- Fix event codes for INST_RETIRED, CPU_CLK_UNHALTED.
- Fix OFFCORE_REQUESTS_OUTSTANDING events
- Add br_inst_retired.all_branches_pebs
- Fill in correct default event

Subject: [PATCH 3/3] oprofile: Fix unit masks of fixed counters on Skylake
Fix another issue noticed by William Cohen.
The unit masks for the fixed counters were incorrect.
Note that the fixed counters exist in two copies, as perf aliases
them to the generic counter version codes.
