...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 full patch series providing th...

DRM's fbdev console uses regular load and store operations to update framebuffer memory. The bochs driver on sparc64 requires the use of I/O-specific load and store operations. We have a workaround, but need a long-term solution to the problem. This patchset changes GEM's vmap/vunmap interfaces to forward pointers of type struct dma_buf_map and updates the generic fbdev emulation to use
