drm/nouveau: introduce nv_device_is_cpu_coherent() Add a function allowing us to know whether a device is CPU-coherent, i.e. accesses performed by the CPU on GPU-mapped buffers will be immediately visible on the GPU side and vice-versa. For now, a device is considered to be coherent if it uses the PCI bus on a non-ARM architecture. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
