Input/Output Request Packet Handling Techniques by a Device Specific Kernel Mode Driver

One or more computing device readable media having computing device executable instructions which when executed perform a method comprising:

• receiving, by a device specific kernel mode driver, a dispatch table including a plurality of input/output manager function pointers;
• sending, by the device specific kernel mode driver to an operating system kernel mode driver, the dispatch table including the plurality of input/output manager function pointers;
• receiving, by the device specific kernel mode driver, a dispatch table including the plurality of input/output manager function pointers and a plurality of operating system function pointers;
• storing, by the device specific kernel mode driver, the dispatch table including the plurality of input/output manager function pointers and the plurality of operating system function pointers;
• creating, by the device specific kernel mode driver, a dispatch table including the plurality of input/output manager function pointers and the plurality of operating system functions wherein one or more of the operating system function pointers are replaced by one or more device specific kernel mode driver function pointers;
• and
• sending, by the device specific kernel mode driver to an input/output manager, the dispatch table including the plurality of input/output manager function pointers and the plurality of operating system functions wherein one or more of the operating system function pointers are replaced by one or more device specific kernel mode driver function pointers.

One or more computing device readable media having computing device executable instructions which when executed perform a method comprising:

• passing a dispatch table including a plurality of input/output manager function pointers from an input/output manager to a device specific kernel mode driver;
• passing the dispatch table including the plurality of input/output manager function pointers from the device specific kernel mode driver to an operating system kernel mode driver;
• passing a dispatch table including the plurality of input/output manager function pointers and a plurality of operating system function pointers from the operating system kernel mode driver to the device specific kernel mode driver;
• storing the dispatch table including the plurality of input/output manager function pointers and the plurality of operating system function pointers in a dispatch table of device specific kernel mode driver;
• passing a dispatch table including the plurality of input/output manager function pointers and the plurality of operating system functions wherein one or more of the operating system function pointers are replaced by one or more device specific kernel mode driver function pointers from the device specific kernel mode driver to the input/output manager.
