Subject: [PATCH v4 15/71] tools/power/turbostat: Switch to new Intel CPU model defines
Date: Wed, 24 Apr 2024 11:14:57 -0700
Message-ID: <20240424181457.41443-1-tony.luck@intel.com>
In-Reply-To: <20240424181245.41141-1-tony.luck@intel.com>
References: <20240424181245.41141-1-tony.luck@intel.com>
Precedence: bulk
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

New CPU #defines encode vendor and family as well as model.

N.B. Copied VFM_*() defines here from <asm/cpu_device_id.h> to avoid
an application picking a second internel kernel header file.
