[PATCH drm-misc-next 0/3] [RFC] DRM GPUVA Manager GPU-VM features
...uch that drivers are free to make use of the DRM GPUVA managers basic functionality and opt-in for other features without setting any feature flags, just by making use of the corresponding functions. The implementation introduces struct drm_gpuva_gem, which serves as abstraction combining a struct drm_gpuva_manager and struct drm_gem_object, similar to what amdgpu does with struct amdgpu_bo_vm. While this adds a bit of complexity it improves the efficiency of tracking evicted GEM objects. [1] provides an alternative implementation using a maple_tree, resulting into a fairly simpler API. [2] points to the fu...

[PATCH drm-next v5 03/14] drm: manager to keep track of GPUs VA mappings
...ecific BO and VM. Just to make it obvious for other people following the discussion, let me quickly sketch up how this approach would look like for the GPUVA manager: 1. We would need a new structure to represent the BO+VM combination, something like: struct drm_gpuva_mgr_gem { struct drm_gpuva_manager *mgr; struct drm_gem_object *obj; struct list_head gpuva_list; }; with a less horrible name, hopefully. 2. Create an instance of struct drm_gpuva_mgr_gem once a GEM becomes associated with a GPUVA manager (VM) and attach it to the GEMs, as by now, "gpuva" list. In amdgpu, for...
