From eec9ffe47f60db8e2ff96b49939d4c2b1be2c36f Mon Sep 17 00:00:00 2001 From: Ben Skeggs Date: Tue, 12 Feb 2019 22:28:13 +1000 Subject: [PATCH] drm/nouveau/top: add function to lookup PRI address for devices Will be using this in upcoming changes to avoid the need for entirely new subdevs to deal with Turing register moves.
