[PATCH 06/22] perf/x86/intel: Add Icelake support

2019-03-18 Thread kan . liang
From: Kan Liang Add Icelake core PMU perf code, including constraint tables and the main enable code. Icelake expanded the generic counters to always 8 even with HT on, but a range of events cannot be scheduled on the extra 4 counters. Add new constraint ranges to describe this to the scheduler.
