[edk2-devel] [RFC][edk2-platform][Add new packages in Platform\Intel directory]

Fri Jun 14 00:55:00 UTC 2019

This looks good to me.  I would suggest that we also capture an overview of the organization and the targeted contents of the different packages in the Platform/Intel/Readme.md or maybe a wiki page.

Thanks,
Isaac

Isaac and Eric:
  Here is the proposal for new packages in Platform\Intel directory.

BoardModulePkg: This package includes the libraries shared between the different board packages. Those libraries are linked by the drivers in the board packages.
DebugFeaturePkg: This package provides the debug features, such as debug library, debug method.
ManageabilityFeaturePkg: This package provides the system management driver, such as Ipmi, Smbios.
DeviceFeaturePkg: This package provides the different device support, such as SIO controller, Network.
UserInterfaceFeaturePkg: This package provides UI related modules, such as Logo, Setup page.

Thanks

Eric,

I have envisioned less granular packages for advanced features.  One of the goals for MinPlatform is to improve usability during porting.  The idea is that you would do basic board porting with minimal effort to get your system functional.  Then you would enable additional features by adding collections of features to your baseline.  Then as a last step optimize out unnecessary things.  This is something like a functionality oriented porting approach.  Get all the functionality you need by building up, then optimize out.  I would characterize Intel's traditional reference platforms as having everything and then adding and removing from a starting point that was very feature rich.  The challenge we seemed to face was that it was hard to remove things with the feature rich starting point.

As an example of functionality oriented porting, say that I set up my basic server port by starting with the Purley open board package.  I port it to my motherboard, then I check out my baseline functionality.  Then I add manageability features by including DSC/FDF from the ManageabilityFeaturePkg that add FV to my MinPlatform port.  And I repeat for other sets of features until I get all of the features that I need.  Then I optimize: for size, speed, to reduce complexity, and so on.  It would be best if this optimization were tool assisted to a great degree, e.g a more sophisticated FMMT that lets one cut out extra components.

My concern is that if we allow very specific feature packages, like the UserAuthenticationPkg, we are very much like today.  Yes, you can select any drivers you need and add to your DSC/FDF.  But that is very quickly overwhelming.  There are hundreds of drivers and what they require is often complex to determine.  Thus we tend to copy something else and customize it.  This tends to lead to lots of technical debt and complexity.

I am thinking that we should target something like 10-20 advanced feature packages that produce one or two (if features have pre-memory components) FV with a set of features and simpler dependencies.  We are just in the early stages of defining what this would look like, and our thinking is evolving.  We have identified Manageability and Debug as feature collections.  I think that there is one for adding USB, network, Bluetooth and such peripheral support.  I think setup browser and UI stuff will go somewhere.  We can mine a few reference platforms for data.

Let's discuss this in person and make a proposal for organization for feature packages and the rules for what goes where.  We can add this proposal to your RFC and I think that will help guide the future development of the Platform\Intel contents.

Regards,
Isaac

Since there is no other module, I think we can use this specific package name to tell people what it is.
It is also good for feature isolation.

Thank you

Hi Jiewen,

So far, I don't have other modules which need to move to this package.

I think UserAuthenticationPkg is too specific, but if others also agree with this name, I'm ok too.

Hi liming, Isaac & Mike,

Any comments about the new package name?

Thanks,
Eric

OK. Do you have any other modules what could be potentially in this package?

I think another option is to name it UserAuthenticationPkg, just like SignedCapsulePkg.

Thank you

I think sample means this is an example about how to enable this feature. Code implemented with production quality. Platform can decide whether to use it or not.

Thanks,

Would you please clarify what "sample" here really means? Not for production? Or something else?

Hi Jiewen,

I think SecuritySamplePkg used to save 1) sample implementation for security related features, 2) it's platform scope feature.
SecurityPkg used to save 1) common security features, 2) It's not a sample implementation.

This is just my proposal, If you have better one, you can raise here.

Thanks,
Eric

Would you please clarify the position of SecuritySamplePkg ?

What is the difference between SecurityPkg and SecuritySamplePkg ?

Isaac, Jiewen & Mike,

I plan to add a new driver named UserAuthentication. This driver shows a sample implementation about how to control user enter setup page. I plan to add a new package in Platform\Intel folder to save this driver. New package name is SecuritySamplePkg. Any comments for this RFC?

Thanks,
Eric
