This patch introduces amdgpu_userqueue_object and its helper functions to creates and destroy this object. The helper functions creates/destroys a base amdgpu_bo, kmap/unmap it and save the respective GPU and CPU addresses in the encapsulating userqueue object. These helpers will be used to create/destroy userqueue MQD, WPTR and FW areas. V7: - Forked out this new patch from V11-gfx-userqueue patch to prevent that patch from growing very big. - Using amdgpu_bo_create instead of amdgpu_bo_create_kernel in prep for eviction fences (Christian) V9: - Rebase V10: - Added Alex's R-B Cc: Alex Deucher <alexander.deucher@amd.com> Cc: Christian Koenig <christian.koenig@amd.com> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Shashank Sharma <shashank.sharma@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
