Routine Description:
This routine allocates the adapter channel specified by the adapter
object. Next a scatter/gather list is built based on the MDL, the
CurrentVa and the requested Length. Finally the driver's execution
function is called with the scatter/gather list. The adapter is
released after the execution function returns.
The scatter/gather list is freed by calling PutScatterGatherList.
Arguments:
DmaAdapter - Pointer to the adapter control object to allocate for the
driver.
DeviceObject - Pointer to the device object that is allocating the
adapter.
Mdl - Pointer to the MDL that describes the pages of memory that are being
read or written.
CurrentVa - Current virtual address in the buffer described by the MDL
that the transfer is being done to or from.
Length - Supplies the length of the transfer.
ExecutionRoutine - The address of the driver's execution routine that is
invoked once the adapter channel (and possibly map registers) have been
allocated.
Context - An untyped longword context parameter passed to the driver's
execution routine.
WriteToDevice - Supplies the value that indicates whether this is a
write to the device from memory (TRUE), or vice versa.
Return Value:
Returns STATUS_SUCCESS unless too many map registers are requested or
memory for the scatter/gather list could not be allocated.
Notes:
Note that this routine MUST be invoked at DISPATCH_LEVEL or above.
The data in the buffer cannot be accessed until the put scatter/gather function has been called.

Routine Description:
This routine is called when the adapter object and map registers are
available for the data transfer. This routine saves the map register
base away. If all of the required bases have not been saved then it
returns. Otherwise it builds the entire scatter/gather list by calling
IoMapTransfer. After the list is built, it is passed to the driver.
Arguments:
DeviceObject - Pointer to the device object that is allocating the
adapter.
Irp - Supplies the map register offset assigned for this callback.
MapRegisterBase - Supplies the map register base for use by the adapter
routines.
Context - Supplies a pointer to the xhal wait control block.

Returns DeallocateObjectKeepRegisters.
