2023-02-23drm/gem-vram: handle NULL bo->resource in move callbackMatthew Auld
The ttm BO now initially has NULL bo->resource, and leaves the driver the handle that. However it looks like we forgot to handle that for ttm_bo_move_memcpy() users, like with vram-gem, since it just silently returns zero. This seems to then trigger warnings like: WARNING: CPU: 0 PID: 1 at drivers/gpu/drm/drm_gem_vram_helper.c:255 drm_gem_vram_offset (??:?) Fix this by calling move_null() if the new resource is TTM_PL_SYSTEM, otherwise do the multi-hop sequence to ensure can safely call into ttm_bo_move_memcpy(), since it might also need to clear the memory. This should give the same behaviour as before. While we are here let's also treat calling ttm_bo_move_memcpy() with NULL bo->resource as programmer error, where expectation is that upper layers should now handle it.

2023-02-06drm/ttm: prevent moving of pinned BOsChristian König
We have checks for this in the individual drivers move callback, but it's probably better to generally forbid that on a higher level. Also stops exporting ttm_resource_compat() since that's not necessary any more after removing the extra checks in vmwgfx.

2023-02-06drm/ttm: clear the ttm_tt when bo->resource is NULLMatthew Auld
In the next few patches, when initially creating a ttm BO, the bo->resource is NULL, and the driver is then expected to handle the initial dummy move. However, if this is created as a system resource the first ttm_tt we create will always have the clear value set to false. Previously the initial ttm_tt would be created in ttm_bo_validate() with the clear parameter always set to true.

2022-07-03mm: shrinkers: provide shrinkers with namesRoman Gushchin
Currently shrinkers are anonymous objects. For debugging purposes they can be identified by count/scan function names, but it's not always useful: e.g. for superblock's shrinkers it's nice to have at least an idea of to which superblock the shrinker belongs. This commit adds names to shrinkers. register_shrinker() and prealloc_shrinker() functions are extended to take a format and arguments to master a name. In some cases it's not possible to determine a good name at the time when a shrinker is allocated. For such cases shrinker_debugfs_rename() is provided. The expected format is: <subsystem>-<shrinker_type>[:<instance>]-<id> For some shrinkers an instance can be encoded as (MAJOR:MINOR) pair.
