Xclipse GPU driver depends on TTM for graphics buffer allocation and management. It is required by customers to add graphics memory swap to improve overall memory efficiency. However TTM's swap feature can't be used since it selects victim buffer by LRU and we can't choose a specific buffer to swap.
Xclipse GPU driver implements its own swap feature by means of APIs of TTM. But the problem is TTM's buffer allocations statistics in ttm_tt.c which are local to that file. Whenever a graphic buffer is swapped out, the size of total page allocation should be decreased but it is not possible from the outside of ttm_tt.c. If the statistics is not maintained well, TTM ends up swapping out TTM buffers globally which is unexpected.
