Subject: [PATCH v2 0/2] RAPL driver fixes for AMD CPUs
Date: Tue, 30 Jul 2024 04:49:16 +0000	[thread overview]
Message-ID: <20240730044917.4680-1-Dhananjay.Ugwekar@amd.com> (raw)

After commit ("x86/cpu/topology: Add support for the AMD 0x80000026 leaf"),
AMD CPUs with 0x80000026 leaf have become CCD(Core Complex Die)-aware and 
this CCD info is reported by the _die_ macros, which earlier used to return
package info.

e.g: Earlier topology_logical_die_id() and topology_logical_package_id()
used to return the same value for all the CPUs even on a multi-die/
multi-CCD system. But after the above mentioned commit, 
topology_logical_die_id() returns the CCD id and 
topology_logical_package_id() returns the package/socket id.

Hence, the RAPL energy-pkg event which uses _die_ macros has to be
fixed, in light of above change.
