I think that exposing RESET_DATA_WITH_NULL_STRING as a public structure
is a good idea -- it indeed looks like something useful for many
platforms and for different purposes.

- However, I'd argue that it should not go into an include file called
"CapsuleResetData.h". The type looks generic and not tied to capsules.

- Additionally, I believe (but I'm not fully sure!) that new structures
under MdeModulePkg/Include/Guid should be named EDKII_*.

If the MdeModulePkg maintainers are OK with these patches in the current
form, I'm fine too; I just thought we might want to consider the above
points. (I certainly suggest waiting for their feedback before starting
work on v2, just to address the above.)

Thanks!

Re: [edk2-devel] [PATCH 1/4] MdeModulePkg: Add reset data difinition and guid

[Michael D Kinney]

Laszlo,

I agree with both your points.  The file name should not imply
that it can only be used for capsule resets.

I also agree that the structure name and GUIDs should use 
EDKII_ and gEdkii prefixes.

I also suggest, since the 2 new GUIDs are not associated with 
a structure (they are used to fill in a GUID value field in a
structure), that they can be declared in the DEC file alone and
do not require the MACRO name or extern declaration in a new .h
file.  The .h file should only contain the new data structure
EDKII_RESET_DATA_WITH_NULL_STRING.

Depending on what modules/libs use EDKII_RESET_DATA_WITH_NULL_STRING,
it may make more sense to add this structure to an existing 
library class .h file.

Best regards,

Mike

The lib class header "MdeModulePkg/Include/Library/ResetUtilityLib.h"
definitely crossed my mind, but I didn't dare suggest it. :)

Re: [edk2-devel] [PATCH 1/4] MdeModulePkg: Add reset data difinition and guid

[Gao, Zhichao]

I think ResetUtilityLib.h is a good place to add the new structure definition.
But I think this lib cannot be consumed in some conditions. The new ResetUtilityLib add a new API which would consume a new API ResetSystem in ResetSystemLib.
As we know different platforms have different instances of ResetSystemLib. And I think all of them do not implement the new API yet. So if they consume the ResetUtilityLib, a link error would happen. As an alternative, I define the structure in the ResetSystemLib.h. And do not use the new API ResetSystemWithSubtype in ResetUtilityLib to transfer the ResetData.
Here are some detail conditions:
The platform normally use its own ResetSystemLib. That would lack the new API implement. If it works with the edk2 master and some driver consume the new API. Then a link error would occur.
If the platform add the new API and it works both with edk2 master and some stable tag before, then a name conflict would occur with the stable tag. Because the new API name is conflict with ResetSystemRuntimeDxe and we already change it to RuntimeServiceResetSystem while we add the new API.

All the above is why I want to define the structure in ResetSystemLib.h and not to use the ResetSystemWithSubtype to transfer the ResetData.

Thanks,
Zhichao
