drm/radeon: track memory statistics about VRAM and GTT usage and buffer moves v2
The statistics are: - VRAM usage in bytes - GTT usage in bytes - number of bytes moved by TTM The last one is actually a counter, so you need to sample it before and after command submission and take the difference. This is useful for finding performance bottlenecks. Userspace queries are also added. v2: use atomic64_t Signed-off-by: Marek Olšák <marek.olsak@amd.com> Reviewed-by: Christian König <christian.koenig@amd.com>
