An example driver and build batch files that has tests for the three intrinsics
The following kernel mode only intrinsics appear to be incomplete:
* __readmsr
* __readcr3
* __writecr3
I am attaching the device driver I augmented in order to test these intrinsics.
We used Visual Studio 2010 and LLVM 3.4 and Clang 3.4 for our testing. We
were using the intrin.h file from r203816. We are also using the Windows XP
DDK, which can be downloaded from
