WCK Driver Memory test fails with more EX non-paged pool usage in win 8 RRS feed

  • Question

  • We are allocating 10 MB+ NonpagedPool memory for our data structure in terms of 70+ bytes chuncks.
     WHCK Driver Memory test is failing with error "Driver test.sys allocated 11.266 KB EX non-paged pool,
     please use NX non-paged pool in the driver to pass this test"

     We tried with NonpagedPoolNx and POOL_NX_OPTIN porting option but it throws the same error.
     Another thing if memory is allocated in larger chunk even if we dont specify NonpagedPoolNx it doesnt give error.

     Kindly reply on this issue.

  • Are you calling ExAllocatePool()? If so try replacing it with ExAllocatePoolWithTag().

  • No. I am using ExAllocatePoolWithTag.

    One more thing I use PagedPool the test passes.
