List of projects for 4.7

List of projects for 4.7

[Wei Liu]

Hi all

Today is that last posting day for new features. And we are two weeks
away from the anticipated freeze date.

I've gone through the outstanding patch series on the list and ask for
input from various core community members. I've enumerated a list
here, which covers several areas of this release and can be used as a
guideline.

Important and close patch, new features:
1. xSplice
2. CPUID levelling
3. ARM ACPI
4. COLO HA
5. RTDS per-vcpu parameter setting
6. Event driven RTDS

Important bug fixes:
1. Intel VT-d flush issue
2. SMEP / SMAP fix
3. QEMU hotplug script fix

Note, it is possible for bug fixes to go in after freeze.

Nice to have, not very complicated patch sets:
1. IOREQ server P2M type
2. QEMU-based PVUSB backend
3. Oxenstored improvement
4. Load bios via toolstack

I think it would be good to use the remaining time to focus on things
that are close, important or both.

Thanks
Wei.

The tool stack change for RTDS scheduler is in good status, but hasn't
collected all Reviewed-by tags...


> 6. Event driven RTDS

The Event driven RTDS has received the Reviewed-by from Dario and me.
It is ready after getting Acked-by.

Thanks,

Actually this is already committed. Good work guys.

Hi, what about "Domain snapshot API"? From a fast search I not found 
recent news about it.

Thanks for any reply and sorry for my bad english.

There has not been any activity during this cycle. Chunyan mostly worked
on PVUSB passthrough (which was merged this morning).

Wei.

The current status:
1) patch for xen: The "mentioning a bug fixed" issue
2) patch for libxc: Acked-by: Wei Liu; Reviewed-by: Dario Faggioli
3) patch for libxl: Acked-by: Wei Liu
4) patch for xl: More examples need to be added to man page

For ARM ACPI, there are about 7 patches which don't get reviewed-by or
acked-by. It still needs some efforts and maybe another two versions to
make them in good shape I think.

What about features which got posted weeks ago already, namely pvscsi?
I should probably rebase ontop of pvusb, but the beef remains the same.

Yes, you can rebase and repost. This feature falls into nice-to-have
category, too.

My assessment of the pending patch: that's two thousand lines of code in
a single patch, which potentially requires quite a few iterations to get
right. Furthermore its prerequisite PVUSB was only merged yesterday,
which has its own defects that needs sorting out first. Given the time
scale, It would be hard for PVSCSI be ready before the freeze.

But worry not, we will review it all the same if you repost.

Wei.

qemu-parts: Gerd Hoffmann would apply the patches after a review of xen
folks - any volunteer? :-)

xen tools parts: V2 will be sent as soon as some last details regarding
V1 have been discussed

What about my pending "pin override" tools related patches? Hypervisor
parts are already committed.

PVSCSI does not depend on PVUSB, beside the merge conflict in
libxl_internal.h, libxl_types_internal.idl and xl_cmdimpl.c.

I'm in the process to rebase v9 from 3b971de..829e03c.

Posted last week. Awaiting initial review.

I will review your patch series today.

That was omitted, because as far as I can tell all toolstack patches
were already acked or reviewed -- you probably should prod Ian to commit
it.
