2024-06-20drm/ttm: increase ttm pre-fault value to PMD sizeZhu Lingshan
ttm page fault handler ttm_bo_vm_fault_reserved() maps TTM_BO_VM_NUM_PREFAULT more pages beforehand due to the principle of locality. However, on some platform the page faults are more costly, this patch intends to increase the number of ttm pre-fault to relieve the number of page faults. When multiple levels of page table is supported, the new default value would be the PMD size, similar to huge page.
