Introduction to SDV
Detecting and evaluating errors in Windows drivers can be challenging, even with the advances that WDF provides. Kernel-mode drivers are asynchronous and massively reentrant, and each driver must follow many complex rules to correctly use hundreds of WDM and KMDF DDI functions. In addition, driver testing is complicated because:
You cannot directly observe an error in the interaction between the driver and Windows itself.
A driver that works correctly most of the time can have subtle errors that occur only in exceptional situations.
If a driver violates implicit usage rules in a way that causes the driver to behave improperly or crash the system, detecting the root cause of that error can be very difficult.
