Previously we were filling it the same as "placements", but in some cases there're valid alternatives that we were ignoring completely. Keeping a back-up memory type helps on several low-mem situations.

This flag allows userspace to give the kernel a hint that it should use a non-snooped resource. To guarantee coherency at all times mappings into userspace are done write combined, so userspace should avoid reading back from those resources.

This is a bit messed up because chan->cli->mutex is a different class, depending on whether it is the global drm client or not. This is because the global cli->mutex lock can be taken for eviction, so locking it before pinning the buffer objects may result in a deadlock. The locking order from outer to inner is: - &cli->mutex - ttm_bo - &drm_client_lock (global

From: Christian K?nig <ckoenig.leichtzumerken at gmail.com> While working on TTM cleanups I've found that the io_reserve_lru used by Nouveau is actually not working at all. In general we should remove driver specific handling from the memory management, so this patch moves the io_reserve_lru handling into Nouveau instead. The patch should be functional correct, but is only compile
