Description yiysun intel_group 2022-04-22 15:42:34 UTC 
Intel Vt-d spec defines Second-Level Accessed/Dirty Support in ecaps. If this bit is set, that means hardware can update the access/dirty flags of second-level page entry. This is helpful to track dirty pages of DMA.

This patch set enables SLAD support and link it with VFIO.
