drm/i915/buddy: track available visible size
Track the total amount of available visible memory, and also track
per-resource the amount of used visible memory. For now this is useful
for our debug output, and deciding if it is even worth calling into the
buddy allocator. In the future tracking the per-resource visible usage
will be useful for when deciding if we should attempt to evict certain
buffers.
v2:
- s/place->lpfn/lpfn/, that way we can avoid scanning the list if the
entire range is already mappable.
- Move the end declaration inside the if block(Thomas).
- Make sure to also account for reserved memory.
