From e8e28c2af16b279b6c37d533e1e73effb197cf2e Mon Sep 17 00:00:00 2001 From: Zhang Rui Date: Wed, 19 Apr 2023 10:44:07 +0800 Subject: powercap: intel_rapl: Support per Interface rapl_defaults rapl_defaults is Interface specific. Although current MSR and MMIO Interface share the same rapl_defaults, new Interface like TPMI need its own rapl_defaults callbacks. Save the rapl_defaults information in the Interface private structure. No functional change. Signed-off-by: Zhang Rui Tested-by: Wang Wendy Signed-off-by: Rafael J.
