similar to: [PATCH] ttm/drm: constify ttm_backend_func structures

The functions ttm_bo_global_init() and ttm_bo_global_release() do not receive an argument of type struct ttm_bo_global. Both take a struct drm_global_reference that contains points to a struct ttm_bo_global_ref. Renaming them reflects this.

TTM uses global memory and BO for backing graphics buffers. These are represented by struct ttm_mem_global and struct ttm_bo_global. Currently, struct ttm_bo_global can only be initialized and released through struct ttm_bo_global_ref. This is a workaround for passing an instance of ttm_mem_global to the BO global initialization code. The use of struct ttm_bo_global_ref makes driver code

Hi Christian, I just wanted to ask if there's something else required to get this patch set reviewed and landed. On top of these two patches, I have a patch set that replaces the driver-specific global-bo-and-mem combos with a single struct ttm_global structure. It further merges struct drm_global into struct ttm_global and implements it such that drivers can either share the global memory

VRAM MM and GEM VRAM are only used with each other. This patch set moves VRAM MM into GEM VRAM source files and cleans up the helper's public interface. Thomas Zimmermann (4): drm/vram: Move VRAM memory manager to GEM VRAM implementation drm/vram: Have VRAM MM call GEM VRAM functions directly drm/vram: Unexport internal functions of VRAM MM drm/vram: Unconditonally set BO call-back

Yes, please! I had it on my TODO list to clean that up for an eternity. Actually I never understood why that should be driver work to setup TTM? I mean can't we just have a module_init/module_exit for TTM? Thanks, Christian. Am 13.08.2018 um 12:24 schrieb Thomas Zimmermann: > TTM uses global memory and BO for backing graphics buffers.

VRAM MM and GEM VRAM are only used with each other. This patch set moves VRAM MM into GEM VRAM source files and cleans up the helper's public interface. Version 2 of the patch set doesn't contain functional changes. I'm reposting due to the rebasing onto the debugfs patches. v2: * updated for debugfs support * fixed typos in comments Thomas Zimmermann (4): drm/vram: Move VRAM

On top of these patches, I have a patch set that provides a single init/release interface for TTM global data. I'll post it when the current patches got some feed back. I'd really like to move the code from drm_global.c back into TTM. It's TTM-specific and

Several simple framebuffer drivers copy most of the TTM code from each other. The implementation is always the same; except for the name of some data structures. As recently discussed, this patch set provides generic memory-management code for simple framebuffers with dedicated video memory. It further converts the respective drivers to the generic code. The shared code is basically the same

Even when core AGP support is compiled in Radeon and Nouveau can also work with the PCI GART. The AGP support was notorious unstable and hard to maintain, so deprecate it for now and only enable it if there is a good reason to do so.
