Hello,
In one of the IOCTLs handled in the driver I’m calling to MmMapLockedPagesSpecifyCache
The goal is to map a contiguous buffer pre allocated by WdfDmaEnablerCreate, WdfCommonBufferCreate to the application.
Currently I’m using MmCached.
Can you please tell in what case I should use MmNonCached ?
From what I know, in case of MmCached, the cache is always coherent. Am I right ?
Thank you,
Zvika
