From 2a13096ac7da07a1bfc9d91fc4a982020e7ded2b Mon Sep 17 00:00:00 2001 From: Rajneesh Bhardwaj Date: Fri, 1 Feb 2019 13:02:29 +0530 Subject: platform/x86: intel_pmc_core: Include Reserved IP for LTR Recently introduced commit "platform/x86: intel_pmc_core: Show Latency Tolerance info <51337cd94d18184601ac0fb4cf1a02b8bbabc3d7> skipped the LTR from a reserved IP. Though this doesn't cause any functional issue but it is needed for the consumers of "ltr_ignore" as the index printing for "ltr_show" is missing. For example, w/o this change, a user that wants to ignore LTR from ME would do something like echo 5 > ltr_ignore but the index for ME is 6. Printing a reserved IP helps to properly calculate LTR ignore offsets. Cc: "David E.
