Subject: [PATCH AUTOSEL 5.18 032/159] tools/power turbostat: fix ICX DRAM power numbers
From: Len Brown <len.brown@...el.com>
[ Upstream commit 6397b6418935773a34b533b3348b03f4ce3d7050 ]
ICX (and its duplicates) require special hard-coded DRAM RAPL units,
rather than using the generic RAPL energy units.
