Subject: [PATCH AUTOSEL 5.17 028/135] tools/power turbostat: fix ICX DRAM power numbers
Date: Mon, 30 May 2022 09:29:46 -0400 [thread overview]
Message-ID: <20220530133133.1931716-28-sashal@kernel.org> (raw)
In-Reply-To: <20220530133133.1931716-1-sashal@kernel.org>
From: Len Brown <len.brown@intel.com>
[ Upstream commit 6397b6418935773a34b533b3348b03f4ce3d7050 ]
ICX (and its duplicates) require special hard-coded DRAM RAPL units,
rather than using the generic RAPL energy units.
