- 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.

If the VMA is being deleted, we don't need to explicity unmap first anymore. The MMU code will automatically merge the operations into a single page tree walk. Signed-off-by: -
