Subject: Re: [PATCH] x86: intel_epb: Set Alder Lake N and Raptor Lake P normal EPB
Date: Thu, 27 Oct 2022 15:30:15 -0700 [thread overview]
Message-ID: <235f4f04-b2ae-4a7f-043b-1cd6a85bd8ea@intel.com> (raw)
In-Reply-To: <20221027220056.1534264-1-srinivas.pandruvada@linux.intel.com>
So, the tl;dr on this is:
The EPB setting is fundamentally a classic power vs. performance
knob. This change helps power a bunch (200+mw) while having a
negligible performance impact (<1% if that), so it's a great
trade-off.
Right?
