Allow overrides on the command line. v2: agd: sqaush in spelling fix and bogus default value warning Reviewed-by: Christian König Signed-off-by: Roger He Signed-off-by: Alex Deucher

drm/amd/amdgpu: store fragment_size in vm_manager

2017-08-17T19:46:08+00:00

adds fragment_size in the vm_manager structure and implements hardware setup for it. Reviewed-by: Christian König Signed-off-by: Roger He Signed-off-by: Alex Deucher

drm/amdgpu: rename VM invalidated to moved

2017-08-17T19:46:08+00:00

That better describes what happens here with the BO. Signed-off-by: Christian König Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher

drm/amdgpu: separate bo_va structure

2017-08-17T19:46:07+00:00

Split that into vm_bo_base and bo_va to allow other uses as well. Signed-off-by: Christian König Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher

drm/amdgpu: drop the extra VM huge page flag v2

2017-08-17T19:46:06+00:00

Just add the flags to the addr field as well. v2: add some more comments that the flag is for huge pages. Signed-off-by: Christian König Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher

drm/amdgpu: cleanup static CSA handling

Move the CSA bo_va from the VM to the fpriv structure. Signed-off-by: Christian König Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher

drm/amdgpu: only move VM BOs in the LRU during validation v2

2017-08-17T19:45:57+00:00

This should save us a bunch of command submission overhead. v2: move the LRU move to the right place to avoid the move for the root BO and handle the shadow BOs as well. This turned out to be a bug fix because the move needs to happen before the kmap. Signed-off-by: Christian König Reviewed-by: Felix Kuehling Acked-by: Chunming Zhou Signed-off-by: Alex Deucher

drm/amdgpu: Support IOMMU on Raven

2017-08-15T18:45:58+00:00

We achieved that by setting S(SYSTEM) and P(PDE as PTE) bit to 1 for PDEs and setting S bit to 1 for PTEs when the corresponding addresses are not occupied by gpu driver allocated buffers. Signed-off-by: Yong Zhao Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/amdgpu: enable huge page handling in the VM v5

2017-07-25T20:35:38+00:00

The hardware can use huge pages to map 2MB of address space with only one PDE. v2: few cleanups and rebased v3: skip PT updates if we are using the PDE v4: rebased, added support for CPU based updates v5: fix CPU based updates once more v6: fix ndw estimation Signed-off-by: Christian König Reviewed-and-tested-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdgpu: increase fragmentation size for Vega10 v2

2017-07-25T20:30:16+00:00

The fragment bits work differently for Vega10 compared to previous generations. Increase the fragment size to 2MB for now to better handle that. v2: handle the hardware setup as well Signed-off-by: Christian König Reviewed-and-tested-by: Felix Kuehling Signed-off-by: Alex Deucher
