Subject: [PATCH 0/3] powercap: Enable RAPL for AMD Fam17h
Date: Wed, 29 Jul 2020 20:52:03 +1000 [thread overview]
Message-ID: <20200729105206.2991064-1-victording@google.com> (raw)
This patch series adds support for AMD Fam17h RAPL counters. As per
AMD PPR, Fam17h support RAPL counters to monitor power usage. The RAPL
counter operates as with Intel RAPL. Therefore, it is beneficial to
re-use existing framework for Intel, especially to allow existing tools
to seamlessly run on AMD.
From the user's point view, this series enables the following two sysfs
entry on AMD Fam17h:
/sys/class/powercap/intel-rapl/intel-rapl:0/energy_uj
/sys/class/powercap/intel-rapl/intel-rapl:0/intel-rapl:0:0/energy_uj
Victor Ding (3):
x86/msr-index: sort AMD RAPL MSRs by address
powercap/intel_rapl_msr: Convert rapl_msr_priv into pointer
powercap: Add AMD Fam17h RAPL support
