[PATCH i-g-t 0/4] Validate VF accesses to VRAM via BAR

[Lukasz Laguna]

Series includes a test to validate VF access to VRAM via BAR. The
following scenarios are covered:
- VF can access all provisioned memory via the VRAM BAR,
- VF cannot access memory beyond what's provisioned via the VRAM BAR,
- VF can access memory via the VRAM BAR after reprovisioning.

Additionally, it introduces a library for VRAM accesses and helper to
iterate over enabled VFs.

Lukasz Laguna (4):
  lib/igt_sriov_device: Add helper to iterate over enabled VFs
  lib/intel_vram: Add library for VRAM accesses
  tests/intel/xe_sriov_flr: Use VRAM access helpers from intel_vram
    library
  tests/intel/xe_sriov_vram: Add test checking VF access to VRAM
