Re: [Patch][edk2-platforms/devel-MinnowBoardMax-UDK2017] Fix SMM stack size issue

["Guo, Mang" <mang.guo@intel.com>]

Hi Mike,

Old SMM stack size was 0x2000 which was not enough for Windows 10 16299 version. Because this version OS needs larger SMM stack size to set variable.
SMM stack size was changed from 0x2000 to 0x4000 to fix this issue.

Updated the patch to provide a complete description of the change in the commit message. 


Thanks,
Mang

Guo,

Can you please provide the old size and
the new size in the commit message?

Also, what changed that required a larger
stack?

Thanks,

Mike
