[PATCH drm-next v2 05/16] drm: manager to keep track of GPUs VA mappings
...specifically to the use cases of the GPUVA
manager, rather than generalizing them too much and re-walk the tree
more than necessary. I think the size of the tree can be up to a couple
100k.
Since some operations may be executed from dma-fence signalling critical
sections I have a use case for mas_preallocate(). I was wondering if I
can ignore the "entry" argument of mas_preallocate() and just pass NULL,
since it's actually never used. What's the purpose of this argument? Or
is it bug?
