[PATCH 0/2] Provide init/release functions for struct ttm_bo_global
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

[RFC] Remove AGP support from Radeon/Nouveau/TTM
Hi guys,
Well let's face it AGP is a total headache to maintain and dead for at least 10+ years.
We have a lot of x86 specific stuff in the architecture independent graphics memory management to get the caching right, abusing the DMA API on multiple occasions, need to distinct between AGP and driver specific page tables etc etc...
So the idea here is to just go ahead and remove the support
