WdfCommonBufferCreateWithConfig return error

NTDEV
1

My dirver called the WdfCommonBufferCreateWithConfig, then trigger an internal exception. And return ntstatus = STATUS_INVALID_DEVICE_REQUEST.

The WDK document says WdfCommonBufferCreateWithConfig return one of the following values:

STATUS_INVALID_PARAMETER
The driver supplied an invalid parameter.
STATUS_INSUFFICIENT_RESOURCES
The framework could not allocate a common buffer object, or the system could not allocate a buffer.

Why return STATUS_INVALID_DEVICE_REQUEST?

Check if you supply a valid WDFDMAENABLER parameter.

WdfCommonBufferCreateWithConfig is a wrapper around the kernel function
AllocateCommonBuffer, which is part of the DMA_ADAPTER. That API can
return various errors, which WdfCommonBufferCreateWithConfig will pass
along.

The two errors you mentioned are merely the errors that this function
can generate on its own. In general, the documentation does not mention
errors that can be returned by the functions each API calls.
