That sounds great, thank you. I must have misunderstood something in the
past. I distinctly remember coming away from a discussion somewhere with
the lesson that CI tweaking had to be done in a separate PR.

Perhaps I mistook an explanation. I guess my mental image was that the
CI run started on "master", grabbing its config from the files in
"master", and then checking out or otherwise applying the patches for
the subject series. If CI indeed *launches* while standing at the HEAD
of the topic branch, then that's great.

(I know from my local CI experimentation that it just runs on whatever
commit I have checked out, modulo uncommitted changes per
<https://bugzilla.tianocore.org/show_bug.cgi?id=2986> -- but I didn't
know if the CI environment inside github / azure was the same.)

I agree that it should be.

Sounds great, thank you. I actually prefer it to be part of the same commit.

Here's what I'm proposing / requesting:

(1) Sean, could you please (pretty please :) ) submit the second patch

  Disable EccCheck for OvmfPkg CI

from your demo PR at

  https://edk2.groups.io/g/devel/message/68541
  https://github.com/tianocore/edk2/pull/1201

stand-alone to the list, so that Ard or myself can ACK it and merge it
separately?

(2) Subsequently, I'm going to take the 2nd patch of the present series,
to which Ard's R-b applies as well:

  https://edk2.groups.io/g/devel/message/68451

and I'll *squash it* into James's

  [PATCH v3 3/6] OvmfPkg/AmdSev: add Grub Firmware Volume Package

And then I'll merge that v3 series.

Thank you!
Laszlo
