of your posting this series), but the CC list is incorrect on this
patch, and (at least) on patch#11 as well.
I'm a stickler myself for being CC'd on any patches per
"Maintainers.txt", so I'm going to request a resending of this series,
with the CC lists extended.
Please run "$EDK_TOOLS_PATH/Scripts/GetMaintainer.py" on every patch in
the series, and add the missing CC's. Manually copying all of the
"confidential computing" reviewers on all of the patches is great, but
we need to keep the usual package-level reviewers/maintainers as well.
In particular, the UefiCpuPkg patches need to be copied to Eric, Ray and
Rahul -- like you actually did in patch#21. Patch#22 also misses the
MdePkg reviewers (Michael, Liming, Zhiguang).
Actually all the UefiCpuPkg maintainers/reviewers are CC'ed in the whole
series. Its just that they are not listed in the git commit Cc tag.
Patch#22 was a single one liner which bumps the version number after the
SNP support is added. I was not sure if MdePkg maintainer will have much
comment so I tried to avoid flooding the inbox -- I guess I should have
copied them. I will resend with Cc tags updated.
I'm truly sorry that this must feel like a cop-out on my part. I won't
deny that I appreciate a breather after the last two, hellishly busy,
two weeks, but I *did* resolve last night to start reviewing this series
today. (I should note that we expect reviewers to start reviewing a
patch set within a calendar week, so my feedback *is* just in time by my
count -- except, I expected to make actual patch review comments.)
If you can resend today with the CC's correct, I'll make an attempt to
start reviewing tomorrow.
Also, let me point this out: we have a nice long CC list now, by virtue
of the "confidential computing" section in "Maintainers.txt", and a
calendar week has passed -- I'd have appreciated seeing comments from
others as well!
