From a0f79082bd1740137371f989dbdcbc19a52d3557 Mon Sep 17 00:00:00 2001 From: Lyude Paul Date: Thu, 1 Feb 2018 13:13:58 -0500 Subject: [PATCH] drm/nouveau: Add support for SLCG for Kepler2 That's right, there's still more power saving to go! Starting with kepler 2, nvidia hardware has an additional level of clockgating known as second level clockgating. The details of this are not exact, but it seems to work by waiting for a collection of dependent hardware blocks to be gated before taking affect. As with the previous series, this results in another noticeable drop in power consumption and is programmed in the same manner.
