Hi @lgao4 @mdkinney @pierregondois
Added switch case for ArmV9 processor family inside function DisplayProcessorFamily2 in PrintInfo.c to avoid inappropriate data shown for ArmV9 processors. ArmV9 processor family is added in Smbios 3.8 specification, which should be noted as well. I will push the local branch here to review the changes.

Thanks,
Praveen Sankar

Hi @lgao4 @mdkinney,
I got permission denied error while pushing local branch (which has changes made for the fix). Could you please help me with this ?

Thanks,

Hello Praveen,
if you are trying to push a branch on the tianocore edk2 github repository, I think this is normal to have a permission denied error. You should create a branch on a fork of the edk2 repository and then make a pull request of that branch on the tianocore edk2 repository.
For more information, the following page should help: https://github.com/tianocore/tianocore.github.io/wiki/EDK-II-Development-Process
