From d908175cca901b95ba1628428b216e6e7188e8fb Mon Sep 17 00:00:00 2001 From: Ben Skeggs Date: Mon, 22 Nov 2010 16:05:54 +1000 Subject: [PATCH] drm/nouveau: make fifo.create_context() responsible for mapping control regs The regs belong to PFIFO, they're different for pretty much the same generations we need different PFIFO control for, and NVC0 is going to be even more different than the rest.
