From a6a1a38075661bec189f2bad7912f8861e6ce357 Mon Sep 17 00:00:00 2001 From: Ben Skeggs Date: Tue, 19 Oct 2010 19:57:34 +1000 Subject: [PATCH] drm/nouveau: use object class structs more extensively The structs themselves, as well as the non-sw object creation function are probably very misnamed now. That's a problem for later :) Signed-off-by: Ben Skeggs --- drivers/gpu/drm/nouveau/nouveau_drv.h | 2 - drivers/gpu/drm/nouveau/nouveau_fence.c | 2 +- drivers/gpu/drm/nouveau/nouveau_object.c | 97 ++++++++++++------------ drivers/gpu/drm/nouveau/nv10_graph.c | 1 + drivers/gpu/drm/nouveau/nv20_graph.c | 2 + drivers/gpu/drm/nouveau/nv40_graph.c | 1 + 6 files changed, 53 insertions(+), 52 deletions(-) diff --git a/drivers/gpu/drm/nouveau/nouveau_drv.h b/drivers/gpu/drm/nouveau/nouveau_drv.h index 2fdc26655ca1..2099f04c0b0a 100644 --- a/drivers/gpu/drm/nouveau/nouveau_drv.h +++ b/drivers/gpu/drm/nouveau/nouveau_drv.h @@ -842,8 +842,6 @@ extern int nouveau_gpuobj_gart_dma_new(struct nouveau_channel *, uint32_t *o_ret);
