Using direct memory access (DMA) for data transfers to or from a DMA-capable device has many advantages, including higher speed transfers and lower overall system CPU usage. The kernel-mode driver framework (KMDF) transparently handles much of the required work to implement DMA in a KMDF driver.

Configuring a DMA Channel. Typically, KMDF drivers do not configure DMA channels. However, in certain circumstances, drivers may need to perform channel-specific configuration. For example, a driver might call a custom function that is implemented by the DMA controller by using the following steps: In one of the driver's request handlers, the driver calls …

On Windows 7 and earlier, Kernel-Mode Driver Framework (KMDF) supports only bus-master direct memory access (DMA) devices. Such devices contain their own DMA controllers. On System on a Chip (SoC)–based platforms running Windows 8 and later, the framework also supports system-mode DMA, in which multiple devices share a single multichannel DMA controller.

DMA enabler object The framework's DMA enabler object enables a driver to use the framework's DMA support for a particular device. The driver must create a DMA enabler object for each of its devices that supports DMA operations. DMA transaction object The framework's DMA transaction object represents a single DMA I/O operation.

Apr 17, 2018 · This article introduces an update that installs Kernel-Mode Driver Framework (KMDF) version 1.11 on Windows operating systems. KMDF supports kernel-mode drivers that are written specifically to use it. KMDF driver packages that are built by using Windows Driver Kit for Windows 8 can automatically redistribute and install version 1.11 of the files.

Oct 30, 2006 · Apart from the above, there are also some more advanced documentation, like the DMA support (currently UMDF doesn't support DMA, since it also doesn't support direct hardware access) and the I/O request flow. Apart from the above, currently the most up-to-date and in-depth information about KMDF can be found in the Windows Driver Kit (WDK). Try ...

Apr 19, 2012 · You specify the device's DMA capabilities when calling IoGetDmaAdapterObject(). Map Registers/Bounce buffers will be used according to the DMA capabilities of device. Mapping in 32 bit address space is done using Map Registers. You can refer "DMA Support in KMDF Drivers" for KMDF or this series of blog posts for DMA in WDM drivers for more details.

It was a darn good paper too. What survives from this paper after random editing changes and the removal of all mentions of WDM can be found in the paper "DMA Support In KMDF Drivers." It's still not a bad paper, and if you're interested in DMA (in either WDM or KMDF) we recommend you read it just for the concepts it describes.

Details about porting driver code from WDM to KMDF. ... DMA Support. Performing DMA in a KMDF driver is simpler than in a WDM driver because the framework handles many of the details on behalf of the driver. In essence, the KMDF driver creates a DMA enabler object, specifies the DMA capabilities of the device, and supplies a callback function ...
