| 2025-07-15 | drm/xe/pf: Invalidate LMTT during LMEM unprovisioning | Michal Wajdeczko | |
| Invalidate LMTT immediately after removing VF's LMTT page tables and clearing root PTE in the LMTT PD to avoid any invalid access by the hardware (and VF) due to stale data.

| 2023-12-21 | drm/xe/pf: Introduce Local Memory Translation Table | Michal Wajdeczko | |
| The Local Memory Translation Table (LMTT) provides additional abstraction for Virtual Functions (VF) accessing device VRAM. This code is based on prior work of Michal Winiarski. In this patch we focus only on LMTT initialization. Remaining LMTT functions will be used once we add a VF provisioning to the PF.
