Subject: [PATCH 0/4] x86: Remove direct use of MSR_IA32_ENERGY_PERF_BIAS
Date: Thu, 15 Oct 2020 16:45:59 +0200 [thread overview]
Message-ID: <20201015144603.27933-1-bp@alien8.de> (raw)
From: Borislav Petkov <bp@suse.de>
Hi all,
here's something from my todo list: remove all in-kernel tools use of
that MSR and lastly drop it from the allowed-MSRs-list in the filtering.
Out-of-tree tools should do a similar, trivial conversion.
Constructive comments are, as always, appreciated.
Thx.
