Re: [Question] Testing environment regarding SMM driver

[poxyran <poxyrantab@gmail.com>]

Hello again,

my question is: is it possible to create a SMM driver that
installs/register a SMI handler (in order to call it from a usermode app
in the OS) and test it in the UEFI Shell or do I need to setup up a
dedicated machine with the SMM stack as described in official EDK II
documentation [1]?
