This is a note to let you know that I've just added the patch titled powercap: intel_rapl: Use standard Energy Unit for SPR Dram RAPL domain to the 5.19-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: powercap-intel_rapl-use-standard-energy-unit-for-spr-dram-rapl-domain.patch and it can be found in the queue-5.19 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. >From 4c081324df5608b73428662ca54d5221ea03a6bd Mon Sep 17 00:00:00 2001 From: Zhang Rui <rui.zhang@xxxxxxxxx> Date: Sat, 24 Sep 2022 13:47:36 +0800 Subject: powercap: intel_rapl: Use standard Energy Unit for SPR Dram RAPL domain From: Zhang Rui <rui.zhang@xxxxxxxxx> commit 4c081324df5608b73428662ca54d5221ea03a6bd upstream. Intel Xeon servers used to use a fixed energy resolution (15.3uj) for Dram RAPL domain. But on SPR, Dram RAPL domain follows the standard energy resolution as described in MSR_RAPL_POWER_UNIT. Remove the SPR dram_domain_energy_unit quirk.
