From 89cd6e2071b3d3bc4635fe41461e2bb75b5f2d2d Mon Sep 17 00:00:00 2001 From: Alexandre Courbot Date: Tue, 13 Dec 2016 17:11:30 +0900 Subject: drm/nouveau/gr/gf100: instantiate and reserve GR falcons Create instances for the FECS and GPCCS falcons and use the init() and fini() hooks to reserve them for as long as GR controls them.
