2020-10-30drm/amdkfd: Fix getting unique_id in topologyKent Russell
Since the unique_id is now obtained in amdgpu in smu_late_init, topology misses getting the value during KFD device initialization. To work around this, we use amdgpu_amdkfd_get_unique_id to get the unique_id at read time. Due to this, we can remove unique_id from the kfd_dev structure, since we only need it in the KFD node properties struct Signed-off-by: Kent Russell <kent.russell@amd.com> Reviewed-by: Felix Kuehling <Felix.Kuehling@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2020-09-22drm/amdkfd: Move process doorbell allocation into kfd deviceMukul Joshi
Move doorbell allocation for a process into kfd device and allocate doorbell space in each PDD during process creation. Currently, KFD manages its own doorbell space but for some devices, amdgpu would allocate the complete doorbell space instead of leaving a chunk of doorbell space for KFD to manage. In a system with mix of such devices, KFD would need to request process doorbell space based on the type of device, either from amdgpu or from its own doorbell space.

We still have a few iommu issues which need to address, so force raven as "dgpu" path for the moment.

2020-02-12drm/amdkfd: refactor runtime pm for bacoRajneesh Bhardwaj
So far the kfd driver implemented same routines for runtime and system wide suspend and resume (s2idle or mem). During system wide suspend the kfd aquires an atomic lock that prevents any more user processes to create queues and interact with kfd driver and amd gpu. This mechanism created problem when amdgpu device is runtime suspended with BACO enabled. Any application that relies on kfd driver fails to load because the driver reports a locked kfd device since gpu is runtime suspended. However, in an ideal case, when gpu is runtime suspended the kfd driver should be able to: - auto resume amdgpu driver whenever a client requests compute service - prevent runtime suspend for amdgpu while kfd is in use This change refactors the amdgpu and amdkfd drivers to support BACO and runtime power management.

2019-10-25drm/amdkfd: don't use dqm lock during device reset/suspend/resumePhilip Yang
If device reset/suspend/resume failed for some reason, dqm lock is hold forever and this causes deadlock. Below is a kernel backtrace when application open kfd after suspend/resume failed. Instead of holding dqm lock in pre_reset and releasing dqm lock in post_reset, add dqm->sched_running flag which is modified in dqm->ops.start and dqm->ops.stop. The flag doesn't need lock protection because write/read are all inside dqm lock. For HWS case, map_queues_cpsch and unmap_queues_cpsch checks sched_running flag before sending the updated runlist. v2: For no-HWS case, when device is stopped, don't call load/destroy_mqd for eviction, restore and create queue, and avoid debugfs dump hdqs.
