Could you post the exception message from serial port? Then we could know if UefiCpuPkg/Library/CpuExceptionHandlerLib is used or not?

Hi to all. I'm trying to write some EDK shell app for the latest Intel Skylake CPU, and I need to use a custom GP exception handler during its work. I'm trying to locate the EFI_CPU_ARCH_PROTOCOL by using gEfiCpuArchProtocolGuid, then I'm using the RegisterInterruptHandler protocol function (first with NULL to unregister the existing handler, and then with pointer to my handler function), and it returns me EFI_SUCCESS in both calls. But when I actually get a GP, it doesn't reach my custom handler function, and probably continues to use some kind of default exception handler that prints a default exception message on my serial port. What I am doing wrong? Perhaps I'm compiling my app with a wrong library? Which library should be used for EFI_CPU_ARCH_PROTOCOL to work correctly as expected? _______________________________________________ edk2-devel mailing list [email protected] https://lists.01.org/mailman/listinfo/edk2-devel _______________________________________________ edk2-devel mailing list [email protected] https://lists.01.org/mailman/listinfo/edk2-devel
