Hans-Kristian Arntzen fd4488c3ab vkd3d: Optimise the GPU VA allocator. ...

The GPU VA allocator was allocating memory in a way where dereferencing
GPU VA required a lock + bsearch() to find the right VA range.

Rather than going this route, we turn the common case into O(1) and
lock-free by creating a slab allocator which allows us to lookup a
pointer directly from a GPU VA with (VA - Base) / PageSize.

The number of allocations in the fast path must be limited since we
cannot trivially grow the allocator while remaining lock-free for
dereferences.
