DXGK_MITIGATEDRANGEINFO structure (dispmprt.h)

  • Article

The list of pages in the virtual function’s BARs that need to be mitigated.

Syntax

typedef struct _DXGK_MITIGATEDRANGEINFO {
  ULONG64 BasePageNumber;
  ULONG   PageCount;
  BOOLEAN InterceptReads;
  BOOLEAN InterceptWrites;
} DXGK_MITIGATEDRANGEINFO, *PDXGK_MITIGATEDRANGEINFO;

Members

BasePageNumber

Offset of the range from the beginning of the BAR.

PageCount

Number of pages in the range. A mitigated range size should not exceed 2 GB. When the driver needs to mitigate a range, which is bigger than 2GB, it needs to report multiple consecutive ranges. There is no limit on the number of mitigate ranges the driver can report.

InterceptReads

Set this to TRUE to mitigate reads to the range.

InterceptWrites

Set this to TRUE to mitigates writes to the range.
