From 245dcfe96f6900dbf64e48a350badf4c90fabc2e Mon Sep 17 00:00:00 2001 From: Ben Skeggs Date: Wed, 14 Jan 2015 14:35:35 +1000 Subject: [PATCH] drm/nouveau/bar: namespace + nvidia gpu names (no binary change) The namespace of NVKM is being changed to nvkm_ instead of nouveau_, which will be used for the DRM part of the driver. This is being done in order to make it very clear as to what part of the driver a given symbol belongs to, and as a minor step towards splitting the DRM driver out to be able to stand on its own (for virt). Because there's already a large amount of churn here anyway, this is as good a time as any to also switch to NVIDIA's device and chipset naming to ease collaboration with them. A comparison of objdump disassemblies proves no code changes.
