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.

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.

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.

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

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.

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

    SDMA RLC queues

kfd/mqds: dumps all MQDs of all KFD processes on all GPUs
