drm/amdgpu: Add vm context module param

2017-06-09T15:29:38+00:00

Add VM update mode module param (amdgpu.vm_update_mode) that can used to control how VM pde/pte are updated for Graphics and Compute. BIT0 controls Graphics and BIT1 Compute. BIT0 [= 0] Graphics updated by SDMA [= 1] by CPU BIT1 [= 0] Compute updated by SDMA [= 1] by CPU By default, only for large BAR system vm_update_mode = 2, indicating that Graphics VMs will be updated via SDMA and Compute VMs will be updated via CPU. And for all all other systems (by default) vm_update_mode = 0 Signed-off-by: Harish Kasiviswanathan Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/amdgpu: Move compute vm bug logic to amdgpu_vm.c

2017-06-01T20:00:20+00:00

In review, Christian would like to keep the logic inside amdgpu_vm.c with a cost of slightly slower. The loop is still optimized out with this patch. v2: remove the if statement. Now it is not slower. Signed-off-by: Alex Xie Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/amdgpu: cleanup VM manager init/fini

drm/amdgpu: add limitation for dedicated vm number v4

2017-05-24T21:40:09+00:00

Limit reserved vmids to 1 to avoid taking too many out of commission and starving the system. v2: move #define to amdgpu_vm.h v3: move reserved vmid counter to id_manager, and increase counter before allocating vmid v4: rename to reserved_vmid_num Signed-off-by: Chunming Zhou Reviewed-by: Junwei Zhang Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/amdgpu: fix fundamental suspend/resume issue

2017-05-24T21:39:30+00:00

Reinitializing the VM manager during suspend/resume is a very very bad idea since all the VMs are still active and kicking. This can lead to random VM faults after resume when new processes become the same client ID assigned.
