[edk2-devel] OvmfPkg PlatformCI: Should iasl dependency be updated from 20190215.0.0 ?

[Sean]

Rebecca,

I agree the iasl dependency for CI has not been managed consistently.   
When all of the CI was setup we decided that iasl should be controlled 
by the platform and thus EmulatorPkg, ArmVirt, and OVMF have their own 
extdep.  This gives those platforms control to rev their version as 
necessary for their platform.   We have found it very common in platform 
development for platforms to have different required versions of iasl.exe.

For Core CI (meaning just package builds) we managed iasl in Basetools.  
We decided that this would only need to be updated when newer features 
were used by core components (not very often given the very little ASL 
in edk2 tree).


As for the feed.  Yes they are inconsistent.   We were moving away from 
a global nuget.org feed as it just didn't seem necessary to push to 
nuget.org.  But now we are evaluating ways to move entirely away from 
nuget.  Nuget.exe worked pretty well for Windows development and our 
initial use cases but has definitely created a headache on Linux, MacOS 
and other.  There really isn't a generic package management solution 
that is supported cross platform that has free/high quality/secure 
hosting.  If anyone has ideas please share.


So my suggestion is to hold off for a couple of weeks (unless something 
is broken) and lets see if we can use web downloads from github 
releases.  This should still allow consistency with tools, work cross 
platform, and give the flexibility needed per platform.


Regarding the steps in that document.  In that example it doesn't call 
out all the steps needed as that would just rehash the section before.  
Instead it relies on a user having followed the generic steps in the 
section above (How to Build With Stuart · tianocore/tianocore.github.io 
Wiki 
<https://github.com/tianocore/tianocore.github.io/wiki/How-to-Build-With-Stuart#how-to-build-in-edk2-with-stuart>). 
For example the user would need to have also done:  setup python virtual 
env, install pypi dependencies, and clone source + submodules.


Thanks

Sean
