From 637d97b53cdded02da55d0a25cda6fd6af3bd042 Mon Sep 17 00:00:00 2001 From: Jiri Olsa Date: Sun, 16 Jun 2019 16:03:58 +0200 Subject: [PATCH] perf/x86/rapl: Get quirk state from new probe framework Getting the apply_quirk bool from new rapl_model_match array. And because apply_quirk was the last remaining piece of data in rapl_cpu_match, replacing it with rapl_model_match as device table. The switch to new perf_msr_probe detection API is done.
