drm/amdkfd: Use partial migrations/mapping for GPU/CPU page faults in SVM
This patch implements partial migration/mapping for gpu/cpu page faults in SVM
according to migration granularity(default 2MB). A svm range may include pages
from both system ram and vram of one gpu now. These chagnes are expected to
improve migration performance and reduce mmu callback and TLB flush workloads.
