Hi, Ask ttm to validate buffer from system to vram ttm call driver->bo_move with evict=false which i guess is right as the object will now be in GPU address space. So for the move i need to allocate a temporary GTT space. Here is what i do
setup a tmp ttm_mem_reg with numpages=bo numpages call ttm_bo_mem_space to get gtt space ttm_tt_bind it do my dma blit call ttm_bo_move_accel_cleanup with the dmafence So accel_cleanup call ttm_buffer_object_transfer which ref the fence and create a ghost object to hold the previous location. What i don't get is how and when the ghost object is released, so far for me it seems it's never released and so i quickly run with tons of fence object active while already signaled (not mentioning a bunch of ghost object).
