[PATCH 0/4] drm/amdkfd: Enable device private memory THP support in kfd svm driver

[Xiaogang.Chen <xiaogang.chen@amd.com>]

From: Xiaogang Chen <xiaogang.chen@amd.com>

Use following work for device-private THP support in kfd driver to add
2MB/THP support in migration. The implementation enables efficient migration
of large folios between system memory and device-private memory.

Xiaogang Chen (4):
  drm/amdkfd: Add awareness of THP of device and system RAM in kfd svm
    driver
  drm/amdkfd: Change migration size in CPU/GPU page fault handler to THP
    size
  drm/amdkfd: Apply HMM THP zone device-private memory migration in kfd
    driver
  drm/amdkfd: Apply AMDGPU_PTE_FRAG to pte of gart page table for THP
    mapping
