From 72b96ee29ed6f7670bbb180ba694816e33d361d1 Mon Sep 17 00:00:00 2001 From: Jithu Joseph Date: Thu, 5 Oct 2023 12:51:32 -0700 Subject: platform/x86/intel/ifs: Gen2 Scan test support MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Width of chunk related bitfields is ACTIVATE_SCAN and SCAN_STATUS MSRs are different in newer IFS generation compared to gen0. Make changes to scan test flow such that MSRs are populated appropriately based on the generation supported by hardware. Account for the 8/16 bit MSR bitfield width differences between gen0 and newer generations for the scan test trace event too.
