DRIVER_VERIFIER_DMA_VIOLATION Parameters

Parameter 1 is the only parameter of interest. This parameter identifies the exact violation. If a debugger is attached, an informative message is displayed in the debugger.

Parameter 1	Cause of Error and Debugger Message
0x00 - Miscellaneous DMA error.	This code can represent two kinds of errors as indicated by parameter 2: 0x1 - The driver tried to flush too many bytes to the end of the map register file. Parameter 3 - Number of bytes left in the MDL. Parameter 4 - Number of bytes left requested to be flushed. 0x2 - Windows has run out of contiguous map registers. Parameter 3 - Map registers needed. Parameter 4 - Number of contiguous map registers.
0x01	The performance counter has decreased. The old and new values of the counter are displayed.
0x02	The performance counter has increased too fast. The counter value is displayed in the debugger.
0x03	The driver freed too many DMA common buffers. Usually this means it freed the same buffer two times. Parameter 2 - Number of extra common buffers freed.
0x04	The driver freed too many DMA adapter channels. Usually this means it freed the same adapter channel two times. Parameter 2 - Number of extra adapter channels freed.
0x05	The driver freed too many DMA map registers. Usually this means it freed the same map register two times. Parameter 2 - Number of extra map registers freed.
0x06	The driver freed too many DMA scatter/gather lists. Usually this means it freed the same scatter/gather list two times. Parameter 2 - Allocated scatter-gather lists. Parameter 3 - Freed scatter-gather lists.
0x07	The driver tried to release the adapter without first freeing all its common buffers. Parameter 2 - Pointer to the DMA adapter. Parameter 3 - Number of outstanding common buffers. Parameter 4 - Pointer to the corresponding internal verifier data.

0x09	The driver tried to release the adapter without first freeing all map registers. Parameter 2 - Pointer to the DMA adapter. Parameter 3 - Number of outstanding map registers. Parameter 4 - Pointer to the corresponding internal verifier data.
0x0A	The driver tried to release the adapter without first freeing all its scatter/gather lists. Parameter 2 - Pointer to the DMA adapter. Parameter 3 - Number of outstanding scatter-gather lists. Parameter 4 - Pointer to the corresponding internal verifier data.
0x0B	The driver has allocated too many adapter channels at the same time (Only one adapter channel is permitted per adapter.) Parameter 2 - Outstanding adapter channels.
0x0C	The driver tried to allocate too many map registers at the same time. Parameter 2 - Required map registers. Parameter 3 - Maximum map registers.
0x0D	The driver did not flush its adapter buffers. Parameter 2 - Number of bytes mapped. Parameter 3 - Maximum number of bytes that can be mapped at a time.
0x0E	The driver tried a DMA transfer without locking the buffer. The buffer in question was in paged memory. Parameter 2 - Address of the DMA buffer MDL.
0x0F	The driver or the hardware wrote outside its allocated DMA buffer. Parameter 2 is the Violation code. 0x01 : The tag before the DMA buffer has been modified.Expected tag is DmaVrfy0. Parameter 3 - Buffer length. Parameter 4 - Buffer start. 0x02 : The tag after the DMA buffer has been modified. Expected tag is DmaVrfy0. Parameter 3 - Buffer length. Parameter 4 - Buffer start. 0x03 : Free map register was overwritten. Parameter 3 - Corruption address. Expected fill pattern is 0x0F. 0x04 : Padding before the buffer has been incorrectly modified. Parameter 3 - Buffer start. Expected padding is 0x0F. Parameter 4 - Corruption address. 0x05 : Padding after the buffer has been incorrectly modified. Parameter 3 - Buffer start. Parameter 4 - Corruption address. Expected padding pattern is 0x0F.
0x10	The driver tried to free its map registers while some were still mapped. Parameter 2 - Number of registers still mapped.
0x11	The driver has too many outstanding reference counts for the adapter. Parameter 2 - Reference count. Parameter 3 - Pointer to the DMA adapter. Parameter 4 - Pointer to the corresponding internal verifier data.
0x13	The driver called a DMA routine at an improper IRQL. Parameter 2 is the Violation code. 0x01 : Current IRQL is different than expected. Parameter 3 - Expected IRQL. Parameter 4 - Current IRQL. 0x02 : Current IRQL is higher than expected. Parameter 3 - Expected maximum IRQL. Parameter 4 - Current IRQL.
0x14	The driver called a DMA routine at an improper IRQL.
0x15	The driver tried to allocate too many map registers. Parameter 2 - Allocated map registers. Parameter 3 - Maximum map registers.
0x16	The driver tried to flush a buffer that is not mapped. Parameter 2 - Address in the system virtual space of the map register. Parameter 3 - Pointer to the corresponding internal verifier data.
0x18	The driver tried a DMA operation by using an adapter that was already released and no longer exists. Parameter 2 - Pointer to the DMA adapter. Parameter 3 - Pointer to the corresponding internal verifier data.
0x19	The driver passed a null DMA_ADAPTER value to a HAL routine.

Resolution

This bug check can only occur when Driver Verifier has been instructed to monitor one or more drivers. If you did not intend to use Driver Verifier, you should deactivate it. You might also consider removing the driver that caused this problem.

If you are the driver writer, use the information obtained through this bug check to fix the bugs in your code.
