From ebb945a94bba2ce8dff7b0942ff2b3f2a52a0a69 Mon Sep 17 00:00:00 2001 From: Ben Skeggs Date: Fri, 20 Jul 2012 08:17:34 +1000 Subject: drm/nouveau: port all engines to new engine module format This is a HUGE commit, but it's not nearly as bad as it looks - any problems can be isolated to a particular chipset and engine combination. It was simply too difficult to port each one at a time, the compat layers are *already* ridiculous. Most of the changes here are simply to the glue, the process for each of the engine modules was to start with a standard skeleton and copy+paste the old code into the appropriate places, fixing up variable names etc as needed. v2: Marcin Slusarz - fix find/replace bug in license header v3: Ben Skeggs - bump indirect pushbuf size to 8KiB, 4KiB barely enough for userspace and left no space for kernel's requirements during GEM pushbuf submission. - fix duplicate assignments noticed by clang v4: Marcin Slusarz - add sparse annotations to nv04_fifo_pause/nv04_fifo_start - use ioread32_native/iowrite32_native for fifo control registers v5: Ben Skeggs - rebase on v3.6-rc4, modified to keep copy engine fix intact - nv10/fence: unmap fence bo before destroying - fixed fermi regression when using nvidia gr fuc - fixed typo in supported dma_mask checking Signed-off-by: Ben Skeggs --- drivers/gpu/drm/nouveau/nouveau_ttm.h | 21 +++++++++++++++++++++ 1 file changed, 21 insertions(+) create mode 100644 drivers/gpu/drm/nouveau/nouveau_ttm.h (limited to 'drivers/gpu/drm/nouveau/nouveau_ttm.h') diff --git a/drivers/gpu/drm/nouveau/nouveau_ttm.h b/drivers/gpu/drm/nouveau/nouveau_ttm.h new file mode 100644 index 000000000000..9f4d2715584b --- /dev/null +++ b/drivers/gpu/drm/nouveau/nouveau_ttm.h @@ -0,0 +1,21 @@ +#ifndef __NOUVEAU_TTM_H__ +#define __NOUVEAU_TTM_H__ + +static inline struct nouveau_drm * +nouveau_bdev(struct ttm_bo_device *bd) +{ + return container_of(bd, struct nouveau_drm, ttm.bdev); +} + +extern const struct ttm_mem_type_manager_func nouveau_vram_manager; +extern const struct ttm_mem_type_manager_func nouveau_gart_manager; +extern const struct ttm_mem_type_manager_func nv04_gart_manager; + +struct ttm_tt *nouveau_sgdma_create_ttm(struct ttm_bo_device *, + unsigned long size, u32 page_flags, + struct page *dummy_read_page); + +int nouveau_ttm_init(struct nouveau_drm *drm); +void nouveau_ttm_fini(struct nouveau_drm *drm); + +#endif -- cgit v1.2.3
