From cf5f8aa6885874f6490b11507d3c0c86fa0a11f4 Mon Sep 17 00:00:00 2001 From: Chuansheng Liu Date: Mon, 4 Jul 2016 08:52:51 +0800 Subject: [PATCH] Update the maximum depth of C-state from 6 to 9 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Currently, CPUIDLE_STATE_MAX has been defined as 10 in the cpuidle head file, and max_cstate = CPUIDLE_STATE_MAX – 1, so 9 is the right maximum depth of C-state. This change is reflected in one place of the kernel-param file, but not in the other place where I suggest changing.
