Hi all,
This patch series embeds drm_gem_object into struct radeon_bo and adjusts
any references. I've decided against embedding the gem stuff into struct
ttm_bo because
- vmwgfx doesn't use gem and
- ttm is used for implementing the memory management, whereas gem provides
the userspace interface (I know, there's some overlap there, but that's
not really a new problem).
Please review and consider merging for -next.
Yours, Daniel

drm/radeon: embed struct drm_gem_object
drm/radeon: introduce gem_to_radeon_bo helper
drm/radeon: kill radeon_bo->gobj pointer

It looks like this has finally been / is finally going to be addressed. 2) The gem object is too specialized for general purpose use: a) The shmem member has no natural use with TTM except possibly as a persistent swap storage, but in an ideal world, TTM would talk to the swap cache directly so in the longer term there is no need for the shmem object at all. b) Implementations may want to use other user-space visible objects than buffer objects: For example fence objects or CPU synchronization objects. The common traits of / operations on these are user-space visibility, inter-process visibility, refcounting and destruction when the relevant file is closed. Hence a class that provides only the user-space handles, naming (flink), refcounting and registering with a file handle would be the best choice of a "base" class. Traditional Gem objects could derive from those and provide any extra *generic* members needed for buffer objects. This doesn't really affect your work though. Just some comments on why vmwgfx don't use GEM objects by default and how they could be made optimal for TTM-aware drivers.

Chris Wilson is working on a gem_vm for i915 that employs a address_space per bo and directly manages swap entries and has its own page allocator (actualy cflushed page cache). I haven't yet looked into this closely (especially the ttm part), but this might (at least in parts) be shareable between i915 and ttm.

Yeah, I've noticed that vmwgfx is the (sometimes) sole user of many of the more fancy stuff in ttm. And I also don't like the duplication between gem and ttm. My plan (i.e. wishful thinking) is to have a common set of helper functions that can be shared between i915, radeon and nouveau and any other driver with a gem-like interface (i.e. buffer-objects + execbuffer, gpu<->cpu sync abstracted away by the kernel). Leaving the cracy stuff for drivers that need it (vmwgfx). Nothing concrete though (besides a new testing rig to start hacking on nouveau), I'll intend to simply plow along, hunting for common patterns. > Thanks, > /Thomas Yours, Daniel -- Daniel Vetter Mail: daniel@ffwll.ch Mobile: +41 (0)79 365 57 48 ^ permalink raw reply [flat|nested] 8+ messages in thread

I actually think the only thing which is currently vmwgfx-specific are the ttm_objects and the ttm_locks. TTM objects could really be replaced by gem objects with the bo-specific part stripped, as discussed above. And then there is the ttm lock to allow concurrent execbufs running. /Thomas > >> Thanks, >> /Thomas >> > Yours, Daniel > ^ permalink raw reply [flat|nested] 8+ messages in thread
