drm/amdgpu: use spin_lock_irqsave to protect vm_manager.pasid_idr

2019-03-13T21:02:38+00:00

[ Upstream commit 0a5f49cbf9d6ad3721c16f8a6d823363ea7a160f ] amdgpu_vm_get_task_info is called from interrupt handler and sched timeout workqueue, we should use irq version spin_lock to avoid deadlock.

drm/amdgpu: Fix SDMA TO after GPU reset v3

[ Upstream commit d8de8260a45aae8f74af77eae9a162bdc0ed48d2 ] After GPU reset amdgpu_vm_clear_bo triggers VM flush but job->vm_pd_addr is not set causing SDMA TO. v2: Per advise by Christian König avoid flushing VM for jobs where job->vm_pd_addr wasn't explicitly set. v3: Shortcut vm_flush_needed early.

drm/amdgpu: Need to set moved to true when evict bo

2018-08-28T17:42:48+00:00

Fix the VMC page fault when the running sequence is as below: 1.amdgpu_gem_create_ioctl 2.ttm_bo_swapout->amdgpu_vm_bo_invalidate, as not called amdgpu_vm_bo_base_init, so won't called list_add_tail(&base->bo_list, &bo->va). Even the bo was evicted, it won't set the bo_base->moved. 3.drm_gem_open_ioctl->amdgpu_vm_bo_base_init, here only called list_move_tail(&base->vm_status, &vm->evicted), but not set the bo_base->moved. 4.amdgpu_vm_bo_map->amdgpu_vm_bo_insert_map, as the bo_base->moved is not set true, the function amdgpu_vm_bo_insert_map will call list_move(&bo_va->base.vm_status, &vm->moved) 5.amdgpu_cs_ioctl won't validate the swapout bo, as it is only in the moved list, not in the evict list. So VMC page fault occurs. Signed-off-by: Emily Deng Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/amdgpu: Adjust the VM size based on system memory size v2

2018-08-27T19:48:25+00:00

Set the VM size based on system memory size between the ASIC-specific limits given by min_vm_size and max_bits. GFXv9 GPUs will keep their default VM size of 256TB (48 bit). Only older GPUs will adjust VM size depending on system memory size. This makes more VM space available for ROCm applications on GFXv8 GPUs that want to map all available VRAM and system memory in their SVM address space. v2: * Clarify comment * Round up memory size before >> 30 * Round up automatic vm_size to power of two Signed-off-by: Felix Kuehling Acked-by: Junwei Zhang Reviewed-by: Huang Rui Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/scheduler: remove sched field from the entity

2018-07-25T20:06:26+00:00

The scheduler of the entity is decided by the run queue on which it is queued. This patch avoids us the effort required to maintain a sync between rq and sched field when we start shifting entites among different rqs.
