Subject: [PATCH 13/44] tools/power turbostat: further decode MSR_IA32_MISC_ENABLE
Date: Wed, 1 Mar 2017 00:27:17 -0500 [thread overview]
Message-ID: <e651262477c6d8cba79dffc1a6039da43d9c96b0.1488345270.git.len.brown@intel.com> (raw)
In-Reply-To: <20170301052748.27810-1-lenb@kernel.org>
In-Reply-To: <678a3bd1b3de6d2ebf604e7d708bc8150bb667e9.1488345270.git.len.brown@intel.com>
From: Len Brown <len.brown@intel.com>
Decode MISC_ENABLE.NO_TURBO,
also use the #defines in msr-index.h for decoding this register
cpu0: MSR_IA32_MISC_ENABLE: 0x00850089 (TCC EIST MWAIT TURBO)
Although it is not architectural, decode also
MSR_IA32_MISC_ENABLE.prefetch-disable (bit-9).
documented to be present on: Core, P4, Intel-Xeon
reserved on: Atom, Silvermont, Nehalem, SNB, PHI ec.
