Subject: [PATCH 2/4 RESEND] [intel_ips] old_cpu_power is wrongly divided by 65535 in ips_monitor()
Date: Tue, 12 Oct 2010 14:41:19 +0800 [thread overview]
Message-ID: <1286865679-22941-1-git-send-email-chaohong.guo@linux.intel.com> (raw)
The variable old_cpu_power is used to save the value of THM_CEC
register. In get_cpu_power(), it will be divided by 65535.
