Opening Xen 4.4.1-pre for backports

Opening Xen 4.4.1-pre for backports

[Ian Jackson]

I have updated xen/Makefile's version number.  I take it we should be
considering backport requests to apply to 4.4, where applicable, now ?

What is our backport policy for 4.4.1 ?  Same as 4.3.x was ?

Ian.

I was about to do that, together with the MAINTAINERS update,
together with my first batch of backports.

I suppose so.

I'd like to see at least the following backported to Xen 4.4.1:

- pygrub fixes (rhel7 beta support)
- qemu-upstream hvm vcpu hotplug patches (actually these seem to be already in qemu-upstream-4.4)
- RTC fixes (win2k3 crash fix)
- Konrad's serial console (SOL/AMT) patches / Broadcom TruManage NetXtreme UART patches

I guess you mean 4c15a82f, c7e35c6e, and 6d27a537 here. I'm not
sure I want to copy them over that quickly.

While for the .1 stable release we generally apply somewhat
relaxed backporting rules, I'd still see some sort of justification
for such a feature backport. Only bug fixes would generally be
considered without further justification.

Yep. I recall these were discussed during the 4.4-rc cycle and the thought was 
the RTC fixes would first go to master, and then after 4.4.0 release get backported to 4.4.1. 
Whatever timing is good..

Well having a working serial console (SOL/AMT) also for new hardware
is kind of important.. These patches sounded like they'll enable
serial on new/upcoming devices. 

Konrad can probably comment more about those.

The AMT should work without trouble with Xen 4.4.

The issue with AMT was that the 'Broadcom TruManage' patch inadvertly
made the AMT not work.

They aren't really that new - they were cheap and I needed some PCIe serial
cards and these fit the bill - except that they did not work with Xen.
Now they do.

I would say no - because they are not critical (they are nice to have) and
they are not used that often (the normal user does not use the serial console
that often).

But they are pretty easy to apply if somebody wants has a need for it
right away.

For what it is worth, these patches have been running in XenServer from
around the time they were presented on the list, and we have had no
problems at all with them.  (In fairness, they had specifically fixed
the identified regressions as part of being posted.)

It's much easier if you give exact commit ids.  I guess you mean
dd03048708af072374963d6d0721cc6d4c5f52cf ?

I have added it to my to-backport list.

Ian.

Following for PVH would be a good candidate also:

c30c544b199f70eada597c7352cdcb44648f6dcd : pvh: call pit_init for pvh also
