[PATCH for-4.16 0/2] CHANGELOG: start to populate entries for 4.16

[Roger Pau Monne]

Hello,

The following changes are preparation work for the 4.16 release. This
is my first pass at the log for the release, it's likely missing more
entries.

I'm Ccing all maintainers in this cover letter and also in patch #2 for
further feedback on missing items.

Thanks, Roger.

One day off is not really a problem, but I wonder how you ended up with the
8th. The tag was made on the 7th, and the commit that was tagged had been
made on the 6th.

Both the announcement and the blog post where on the 8th, so I think
that's the official release date, not really when the tag was made.

The announcement was made on the 8th.  The release deliverables are
generally prepped the day before the formal release.

I would add "Early" or something similar because this can only work in a 
constrained setup.

I've used limited instead of early, as using early could be confused
with early boot support or some such IMO.

Can I get a bit more information about those items? Just a pointer to
the commit messages would be helpful so that I can try to write a more
comprehensive entry (or maybe it's just me not knowing anything about
Arm that fails to understand it).

I agree, the text is not quite clear, I will try to come with a better one.

Thanks. I've added:

 - CPU feature leveling on arm64 platform with heterogeneous cores.
 - Handle register accesses as 32/64bit on Arm depending on the processor
   bitness.

Let me know if that's not accurate.

Roger.

I would say:
- Fix coprocessor register accesses on Arm to use the proper 32/64bit access size.

I would suggest s/coprocessor/system/ because the changes was targeting 
arm64.

...
The extended regions are ranges of unused address space exposed to domains
as
"safe to use" for special memory mappings.

I've worded this as:

"Report unpopulated memory regions safe to use for foreign mappings,
Arm and device tree only."

As "extended regions" was IMO too vague. Let me know if that's OK.

I think, it is OK. Nit: maybe replace "foreign" with "foreign/grant"? I 
would be OK either way.

Maybe, I would consider grants as foreign mappings also, ie: the
memory is foreign to the domain, but I can see this being confusing as
we have a specific kind of mappings that are named foreign.

Does replacing foreign with external seem better?

Fine with me, thank you.


BTW, I noticed that "Support of generic DT IOMMU bindings for SMMU V2 
(Arm)" is not mentioned. Looks like the support has reached upstream 
during the 4.16 release cycle, so worth adding here.

Yes you are right this should be added.

I think you can expand this:

- greatly improved gitlab-ci based automated tests:
    - 32-bit Arm builds
    - x86 full system tests

Or with single lines only:

- 32bit Arm builds to the gitlab-ci automated tests
- x86 full system tests to the gitlab-ci automated tests

Thanks!  Dropped the CC list for this mail:
