drm/amdgpu:partially revert 1cfd8e237f0318e330190ac21d63c58ae6a1f66c

found RING0 test fail after S3 resume regression, which is introduced by 1cfd8e237f0318e330190ac21d63c58ae6a1f66c Because after suspend VRAM will be cleared, so driver must unpin the GART table(resident in VRAM) during suspend so it can be evicted to system ram and must correspondingly pin it during resume so the GART table could be restored to VRAM.

drm/amdgpu:fix NULL pointer access during drv remove

2017-12-06T17:47:50Z

NULL pointer is because original logic will step into set_pde_pte() even after the gart.ptr is freed due to there are twice gart_unbind() on all gart area. also, there are other minor fixes: 1,since gart_init only create dummy page, the corresponding gart_fini shouldn't do more like unbinding all GART, this is unnecessary because in driver fini stage all GART unbinding had already been done during each IP's SW_FINI (GMC's SW_FINI is the last one called), so remove the step for the GART unbinding in gart_fini(). 2,gart_fini() is already invoked during each GMC IP's gart_fini routine,e.g. gmc_vx_0_gart_fini(), so no need to manually call it during ttm_fini(). 3,amdgpu_gem_force_release() should be put ahead of amdgpu_vm_manager_fini() Signed-off-by: Monk Liu Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/amdgpu:cleanup GMC & gart garbage function

2017-12-06T17:47:50Z

for gart_ram_alloc/free, they are never used in driver thus ripe them out totally. for gart_vram_pin/unpin, they are not needed becuase we can use bo_creat_kernel/free to replace the original manual way in the gart_vram_alloc/free, thus gart_vram_pin/unpin can also be riped out.

drm/amdgpu: add automatic per asic settings for gart_size

2017-08-24T15:48:41Z

We need a larger gart for asics that do not support GPUVM on all engines (e.g., MM) to make sure we have enough space for all gtt buffers in physical mode. Change the default size based on the asic type. Reviewed-by: Christian König Signed-off-by: Alex Deucher
