From 772c09739ea81e589c42bd8e063119a5fdf38176 Mon Sep 17 00:00:00 2001 From: Angel Pons Date: Fri, 4 Jun 2021 12:57:21 +0200 Subject: cpu/intel/model_206ax/acpi.c: Do not report P_BLK IO MWAIT redirection is disabled, which means reads to the P_LVL2 and P_LVL3 "registers" will never produce any C-state transition requests.
