This is the full patch set for cleaning up the TTM global-state handling
and offering a nice interface for drivers. The first 3 patches have been
discussed on dri-devel already.
Patch [01] adds struct ttm_global, a data structure that gives drivers
a handle ot the global TTM state.
Patches [02] to [13] convert all TTM drivers to struct ttm_global.
Patches [14] and [15] remove unused code.
Patches [16] to [18] merge the functionality of struct drm_global_reference
into the implementation of struct ttm_global and remove the former.
I'd really like to see patches [01] to [15] being merging in one way or the
other. Using struct ttm_global allows for sharing code that touches TTM
internals, and it gets drivers out of the way for the cleanup of the final
3 patches.
One question was if the current infrastructure around drm_global_reference
isn't over-engineered and could be simplified. For now, I took the existing
ref-counting as it is in drm_global.c. This can certainly be simplified if
prefered.
