Discussion

Tier 1 sparse buffers allow the following:

  • Partial memory backing at sparse page granularity.

  • Defined behavior for accessing an unbacked buffer range.

An unbacked buffer range indicates a range within the buffer that doesn’t have memory backing at a given point in time. Accessing an unbacked buffer range of a sparse buffer produces the following results:

  • Reading return zero.

  • Writing produces no result.
