[edk2] [PATCH 10/10] MdeModulePkg/ResetSystemPei: Add reset notifications in PEI
Posted by Ruiyu Ni 6 years, 9 months ago 
From: Bret Barkelew <brbarkel@microsoft.com>

The Reset Notification protocol is added in UEFI spec to support
reset notification mechanism in the DXE phase.
This patch adds similar EDKII specific Reset Notification PPI to PEI
phase to provide the same support.

How about adding "and after EDKII_PLATFORM_SPECIFIC_RESET_HANDLER_PPI" 
at the end of the sentence?

And also need enhance the comments in 
MdeModulePkg\Include\Ppi\PlatformSpecificResetFilter.h to state it will 
be processed before EDKII_PLATFORM_SPECIFIC_RESET_NOTIFICATION_PPI 
instead of EDKII_PLATFORM_SPECIFIC_RESET_HANDLER_PPI.

And also need enhance the comments in 
MdeModulePkg\Include\Ppi\PlatformSpecificResetHandler.h to state it will 
be processed after EDKII_PLATFORM_SPECIFIC_RESET_NOTIFICATION_PPI 
instead of EDKII_PLATFORM_SPECIFIC_RESET_FILTER_PPI.


Thanks,
Star
