Fixes a use-after-free due to a race condition in ttm_bo_cleanup_refs_and_unlock, which allows one task to reserve a BO and destroy its ttm_resv while another task is waiting for it to signal in reservation_object_wait_timeout_rcu. v2: * Always initialize bo->ttm_resv in ttm_bo_init_reserved (Christian König) Fixes: 0d2bd2ae "drm/ttm: fix memory leak while individualizing BOs" Reviewed-by: Chunming Zhou <david1.zhou@amd.com> # v1 Reviewed-by:

Enabling of ACP in hw_init does away with requirement of order of probe on designware_i2s and acp dma driver. designware_i2s reads i2s registers and this use to fail if acp dma driver was not probed prior to it.

Accessing the THIS_MODULE directly is only possible when modules are enabled, otherwise we get a build failure: drivers/gpu/drm/amd/amdgpu/amdgpu_virt.c: In function 'amdgpu_virt_init_data_exchange': drivers/gpu/drm/amd/amdgpu/amdgpu_virt.c:331:20: error: dereferencing pointer to incomplete type 'struct module' Further, THIS_MODULE is NULL when the driver is built-in, so the code would likely cause a NULL pointer dereference. This adds an #ifdef check to avoid the compile-time error, plus a NULL pointer check before dereferencing THIS_MODULE. It might be better to find a way to avoid using the module version altogether.

- Usermode Events The current events code implemented some data structures (waitqueue, fifo) that were already implemented in the kernel. The patches below addresses this issue by replacing them with the standard kernel implementation. In addition, they simplify allocation of events IDs and memory for the events. The patches also increase the maximum number of events while maintaining compatibility with the older userspace library. - Remove radeon support Because Kaveri is fully supported in amdgpu and because current and future versions of userspace libraries will only support amdgpu, we removed radeon support from kfd. Current users can move to amdgpu while using the same userspace libraries. - Various bug fixes and cleanups * tag 'drm-amdkfd-next-2017-11-02' of git://people.freedesktop.org/~gabbayo/linux: (26 commits) drm/amdkfd: Minor cleanups drm/amdkfd: Update queue_count before mapping queues drm/amdkfd: Cleanup DQM ASIC-specific ops drm/amdkfd: Register/Deregister process on qpd resolution drm/amdkfd: Fix debug unregister procedure on process termination drm/amdkfd: Avoid calling amd_iommu_unbind_pasid() when suspending drm/amdkfd: Disable CP/SDMA ring/doorbell in MQD drm/amdkfd: Clean up the data structure in kfd_process drm/radeon: deprecate and remove KFD interface drm/amdkfd: use a high priority workqueue for IH work drm/amdkfd: wait only for IH work on IH exit drm/amdkfd: increase IH num entries to 8192 drm/amdkfd: use standard kernel kfifo for IH drm/amdkfd: increase limit of signal events to 4096 per process drm/amdkfd: Make event limit dependent on user mode mapping size drm/amdkfd: Use IH context ID for signal lookup drm/amdkfd: Simplify event ID and signal slot management drm/amdkfd: Simplify events page allocator drm/amdkfd: Use wait_queue_t to implement event waiting drm/amdkfd: remove redundant kfd_event_waiter.input_index ...

VMAs are about to not take references on the VMM they belong to, which means more care is required when handling delayed unmapping. Queuing it on the client workqueue ensures all pending VMA unmaps will have completed before the VMM is destroyed. Signed-off-by: -

This is already handled in the top-level gem_new() ioctl in another manner, but this will be removed in a future commit. Ideally we'd not need to check up-front at all, and let the VMM code handle error checking, but there are paths in the current BO management code where this isn't possible due to map() not always being called during BO creation, and map() calls not being allowed to fail during buffer migration.
