Hi, experts:
Does current EDK2 UEFI Source code include NMI interrupt handler?
There is no UEFI interrupt handling. The PI spec does talk about.
For example:
If a NMI occurred during UEFI POST, BIOS could handle it or not?
If you own the platform, you can deal with it…
The DXE Core links against an CpuExceptionHandlerLib, so if you don’t have a
debugger you can DEBUG print on exceptions.
see:
https://svn.code.sf.net/p/edk2/code/trunk/edk2/UefiCpuPkg/Library/CpuExceptionHandlerLib/DxeCpuExceptionHandlerLib.inf
You can make a custom version of the CpuExceptionHandlerLib.
The problem with NMI is going to be making sure the APs do the same thing, so
you will need to make sure APs do something that makes sense. That will be in
the DXE CPU driver, the other exceptions will not have that issue.
Thanks,
Andrew Fish
