From 34465d9bbec46eb9a8e3bbea36d40d9afdd3beec Mon Sep 17 00:00:00 2001 From: nwhitehorn Date: Sun, 4 May 2014 16:38:21 +0000 Subject: [PATCH] Disable ACPI and P4TCC throttling by default, following discussion on freebsd-current. These CPU speed control techniques are usually unhelpful at best. For now, continue building the relevant code into GENERIC so that it can trivially be re-enabled at runtime if anyone wants it.
