[PATCH 0/11] multi-die/package support
From: Len Brown
Date: Mon Feb 18 2019 - 22:40:24 EST
This patch series does 3 things.
1. Parses the new CPUID.1F leaf to discover multi-die/package topology
2. Exports knowledge of multi-die topology inside the kernel,
and also to user space via the topology sysfs.
3. Updates parts of the kernel that need to know the difference between
a die-scope MSR and a package_scope MSR.
To follow, Kan will send some additional perf-uncore patches for #3.
Also not include here are some updates to user-space utilities,
cpuid, lscpu, turbostat, x86_energy_perf_policy.
Rafael suggests that the most practical way to handle this series
is via the x86 tree.
Thanks,
-Len
