[ 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 the incorrect external id for raven series

2019-03-13T21:04:14+00:00

[ Upstream commit 7e4545d372b560df10fa47281ef0783a479ce435 ] This patch fixes the incorrect external id that kernel reports to user mode driver. Raven2's rev_id is starts from 0x8, so its external id (0x81) should start from rev_id + 0x79 (0x81 - 0x8). And Raven's rev_id should be 0x21 while rev_id == 1.

drm/amdgpu: Transfer fences to dmabuf importer

2019-03-13T21:04:12+00:00

[ Upstream commit 6e11ea9de9576a644045ffdc2067c09bc2012eda ] amdgpu only uses shared-fences internally, but dmabuf importers rely on implicit write hazard tracking via the reservation_object.fence_excl. For example, the importer use the write hazard for timing a page flip to only occur after the exporter has finished flushing its write into the surface. As such, on exporting a dmabuf, we must either flush all outstanding fences (for we do not know which are writes and should have been exclusive) or alternatively create a new exclusive fence that is the composite of all the existing shared fences, and so will only be signaled when all earlier fences are signaled (ensuring that we can not be signaled before the completion of any earlier write). v2: reservation_object is already locked by amdgpu_bo_reserve() v3: Replace looping with get_fences_rcu and special case the promotion of a single shared fence directly to an exclusive fence, bypassing the fence array. v4: Drop the fence array ref after assigning to reservation_object Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=107341 Testcase: igt/amd_prime/amd-to-i915 References: 8e94a46c1770 ("drm/amdgpu: Attach exclusive fence to prime exported bo's.

drm/amdgpu: Set DPM_FLAG_NEVER_SKIP when enabling PM-runtime

commit d33158530660bc89be3cc870a2152e4e9a76cac7 upstream. Based on a similar patch from Rafael for radeon. When using ATPX to control dGPU power, the state is not retained across suspend and resume cycles by default. This can probably be loosened for Hybrid Graphics (_PR3) laptops where I think the state is properly retained.
