[Mesa-dev] [PATCH 0/8] radv: implement sparseBinding

[Bas Nieuwenhuizen]

This implements the sparseBinding feature radv. The feature name is a misnomer,
as all the resources still have to be completely backed by memore. However,
that can be done independently of descriptor generation, so we have to work
with blocks of address space already.

This feature does not need any kernel features. There are some kernel features
that are useful for sparseResidencyBuffer in the works, this series is designed
such that plugging those in and enabling sparseResidencyBuffer is going to take
minimal work.

deqp-vk -n \*sparse\*:

Test run totals:
  Passed:        1261/2981 (42.3%)
  Failed:        0/2981 (0.0%)
  Not supported: 1720/2981 (57.7%)
  Warnings:      0/2981 (0.0%)

As well as no regressions in the complete CTS.
