I think this is either done or obsolete now. Not sure which.

I may have messed up with the update. Was it upstreamed for Xen 4.9 or 
Xen 4.10? For the former, I will just totally remove it from the update.

It was merged in Xen 4.9. We can just remove this from the update. :-)

I am not going to be able to get this done in the time-frame.
If somebody would be interested in picking up the patches I would
be thrilled!

(In the mean-time I have some livepatch patches that I am massaging).

I'm moving the RTDS scheduler to work-conserving scheduler.
The first version of the patch series has been posted at
https://www.mail-archive.com/xen-devel@lists.xen.org/msg117062.html,
after we discussed the RFC patch.

Thanks,

Meng

I would keep that under the PV drivers. No need to have separate items 
for it :).

Patches for the next step have been pending unreviewed for
exactly 2 months. Considering how much review of new
functionality patches by various people I've been doing during
that period of time (not to speak of how much more is waiting
to be reviewed), I find it really unacceptable that such a series
is bottlenecked by having to wait for a single person (Andrew) to
review it. I can fully understand that he has no time to look
through this (non-trivial) series. Others should finally start
stepping up (and not just for pieces where review is easy and can
be done in a few minutes). Otherwise I may find myself forced to
stop reviewing any new functionality patches contributed by
people not otherwise participating in development in meaningful
ways (which would dramatically shrink my to-be-reviewed queue).

I did bring up in the past the theoretically possible model of
contributors having to build up credit for submitting new
functionality patches. Looking at the patch submission rate I
think this needs to be considered seriously, despite its very
obvious drawbacks.

Jan

Xen 4.10 Development Update

[Julien Grall]

This email only tracks big items for xen.git tree. Please reply for items you
woulk like to see in 4.10 so that people have an idea what is going on and
prioritise accordingly.

You're welcome to provide description and use cases of the feature you're
working on.

= Timeline =

We now adopt a fixed cut-off date scheme. We will release twice a
year. The upcoming 4.10 timeline are as followed:

* Last posting date: September 15th, 2017
* Hard code freeze: September 29th, 2017
* RC1: TBD
* Release: December 2, 2017

Note that we don't have freeze exception scheme anymore. All patches
that wish to go into 4.10 must be posted no later than the last posting
date. All patches posted after that date will be automatically queued
into next release.

RCs will be arranged immediately after freeze.

We recently introduced a jira instance to track all the tasks (not only big)
for the project. See: https://xenproject.atlassian.net/projects/XEN/issues.

Most of the tasks tracked by this e-mail also have a corresponding jira task
referred by XEN-N.

I have started to include the version number of series associated to each
feature. Can each owner send an update on the version number if the series
was posted upstream?

Could you add the following project to the list?

*  Change xen.efi build and add SHIM_LOCK verification into efi_multiboot2()
  -  Daniel Kiper

This is probably more 4.11 material but let's have it on the 4.10 list too.
Who knows what may happen.

Thanks,

Daniel

I am working on XEN-70, have already posted rfc. [1]

Also can you please add a xen-jira issue for the ITS ACPI support [2] v2 
patches,
which I have already sent and am working on next rev.

... and answer on x86 category when your items look ARM specific.

This is already existing in Jira. See XEN-75.

But as said at the beginning of the e-mail, this is only tracking big 
features. We can't possible track all small items as the mail would 
become too long.

I don't consider the two features you mention as big and don't see the 
need to track them here. But they are already tracked in Jira.

Cheers,

Xen 4.10 Development Update

[Julien Grall]

This email only tracks big items for xen.git tree. Please reply for items you
woulk like to see in 4.10 so that people have an idea what is going on and
prioritise accordingly.

You're welcome to provide description and use cases of the feature you're
working on.

= Timeline =

We now adopt a fixed cut-off date scheme. We will release twice a
year. The upcoming 4.10 timeline are as followed:

* Last posting date: September 15th, 2017
* Hard code freeze: September 29th, 2017
* RC1: TBD
* Release: December 2, 2017

Note that we don't have freeze exception scheme anymore. All patches
that wish to go into 4.10 must be posted no later than the last posting
date. All patches posted after that date will be automatically queued
into next release.

RCs will be arranged immediately after freeze.

We recently introduced a jira instance to track all the tasks (not only big)
for the project. See: https://xenproject.atlassian.net/projects/XEN/issues.

Most of the tasks tracked by this e-mail also have a corresponding jira task
referred by XEN-N.

I have started to include the version number of series associated to each
feature. Can each owner send an update on the version number if the series
was posted upstream?
