drm/amdgpu: Move KFD parameters to amdgpu (v3)

2018-08-28T16:51:11+00:00

After merging KFD into amdgpu, move module parameters defined in KFD to amdgpu_drv.c, where other module parameters are declared. v2: add kernel-doc comments v3: rebase and fix parameter variable name (Alex) Signed-off-by: Amber Lin Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdgpu: Merge amdkfd into amdgpu

2018-08-28T16:22:42+00:00

Since KFD is only supported by single GPU driver, it makes sense to merge amdgpu and amdkfd into one module. This patch is the initial step: merge Kconfig and Makefile. v2: also remove kfd from drm Kconfig Signed-off-by: Amber Lin Acked-by: Christian König Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdkfd: Use module parameters noretry as the internal variable name

2018-07-12T02:33:06+00:00

This makes all module parameters use the same form. Meanwhile clean up the surrounding code. Signed-off-by: Yong Zhao Reviewed-by: Felix Kuehling Signed-off-by: Felix Kuehling Acked-by: Christian König Signed-off-by: Oded Gabbay

drm/amdkfd: Introduce KFD module parameter halt_if_hws_hang

2018-07-12T02:33:05+00:00

This avoids triggering a GPU reset or otherwise changing the HW state. Instead KFD will hang, which allows HW debugging tools to analyze the problem. Signed-off-by: Yong Zhao Reviewed-by: Felix Kuehling Signed-off-by: Felix Kuehling Acked-by: Christian König Signed-off-by: Oded Gabbay

drm/amdkfd: Add quiesce_mm and resume_mm to kgd2kfd_calls

2018-03-23T19:32:32+00:00

These interfaces allow KGD to stop and resume all GPU user mode queue access to a process address space. This is needed for handling MMU notifiers of userptrs mapped for GPU access in KFD VMs. Signed-off-by: Felix Kuehling Reviewed-by: Oded Gabbay Signed-off-by: Oded Gabbay

drm/amdkfd: Use ordered workqueue to restore processes

2018-03-23T19:30:36+00:00

Restoring multiple processes concurrently can lead to live-locks where each process prevents the other from validating all its BOs. v2: fix duplicate check of same variable Signed-off-by: Felix Kuehling Reviewed-by: Oded Gabbay Signed-off-by: Oded Gabbay

drm/amdkfd: Add module option for testing large-BAR functionality

2018-03-15T21:27:53+00:00

Simulate large-BAR system by exporting only visible memory. This limits the amount of available VRAM to the size of the BAR, but enables CPU access to VRAM. Signed-off-by: Felix Kuehling Acked-by: Oded Gabbay Signed-off-by: Oded Gabbay

drm/amdkfd: Implement KFD process eviction/restore

2018-02-07T01:32:45+00:00

When the TTM memory manager in KGD evicts BOs, all user mode queues potentially accessing these BOs must be evicted temporarily. Once user mode queues are evicted, the eviction fence is signaled, allowing the migration of the BO to proceed. A delayed worker is scheduled to restore all the BOs belonging to the evicted process and restart its queues. During suspend/resume of the GPU we also evict all processes to allow KGD to save BOs in system memory, since VRAM will be lost. v2: * Account for eviction when updating of q->is_active in MQD manager Signed-off-by: Harish Kasiviswanathan Signed-off-by: Felix Kuehling Acked-by: Oded Gabbay Signed-off-by: Oded Gabbay
