[Intel-xe] [PATCH 0/5] Introduce Local Memory Translation Table

[Michal Wajdeczko]

The Local Memory Translation Table (LMTT) is required to support
SR-IOV on discrete GPUs. In addition to the core LMTT code also
introduce helpers that will be used by other upcoming SR-IOV code.

Michal Wajdeczko (5):
  drm/xe: Define DRM_XE_DEBUG_SRIOV config
  drm/xe: Introduce SR-IOV logging macros
  drm/xe/pf: Introduce Local Memory Translation Table
  drm/xe/kunit: Enable CONFIG_PCI_IOV in .kunitconfig
  drm/xe/kunit: Add test for LMTT operations
