Including drm-intel tree to linux-next

Including drm-intel tree to linux-next

[Daniel Vetter]

Hi Steven,

Since about a year ago we've switched drm/i915 to buffer around 2
weeks worth of patches so that we can do decent QA before breaking
everyone's tree when things land in Dave's drm-next. But that also
means we'll miss out a bit in the integration testing -next provides,
which did hurt a bit in recent efforts. Hence can you please include

git://people.freedesktop.org/~danvet/drm-intel drm-intel-next-queued

into linux-next? Probably best to merge it after drm-next. Note that
drm-intel-next are the QA'ed chunks I send off to Dave. Also, any
mailing lists I'm supposed to follow? And if possible please cc
intel-gfx@lists.freedesktop.org besides dri-devel/lkml when conflicts
with that tree pop up (you won't get moderation spam any more, we've
fixed that up).

Thanks, Daniel

I think you want to send this here to Stephen Rothwell. CCed.

This is why I tell people to call me Steve or Steven, but never Stephen,
otherwise people might confuse me with one of the Stephens that also do
kernel development.

Note, this is not the first time I've been confused with someone else.
So don't feel bad ;-)

Oops, indeed picked the wrong mail from my sea of "drm/i915 broke
stuff, again" mails ;-) Sorry for the noise, Steve.

Added from today.  I am in two minds a bit since I really like stuff in
linux-next to have been reviewed and debugged as much as possible.   But
I have added it and will keep an eye on how many problems it causes.

Problem reports will go to you, intel-gfx and dri-devel.  You can follow
linux-next@vger.kernel.org (I sometimes post stuff there that goes
nowhere else (except lkml - which noone seems to notice :-)).

Thanks for adding your subsystem tree as a participant of linux-next.  As
you may know, this is not a judgment of your code.  The purpose of
linux-next is for integration testing and to lower the impact of
conflicts between subsystems in the next merge window. 

You will need to ensure that the patches/commits in your tree/series have
been:
     * submitted under GPL v2 (or later) and include the Contributor's
	Signed-off-by,
     * posted to the relevant mailing list,
     * reviewed by you (or another maintainer of your subsystem tree),
     * successfully unit tested, and 
     * destined for the current or next Linux merge window.

Basically, this should be just what you would send to Linus (or ask him
to fetch).  It is allowed to be rebased if you deem it necessary.

Legal Stuff:
By participating in linux-next, your subsystem tree contributions are
public and will be included in the linux-next trees.  You may be sent
e-mail messages indicating errors or other issues when the
patches/commits from your subsystem tree are merged and tested in
linux-next.  These messages may also be cross-posted to the linux-next
mailing list, the linux-kernel mailing list, etc.  The linux-next tree
project and IBM (my employer) make no warranties regarding the linux-next
project, the testing procedures, the results, the e-mails, etc.  If you
don't agree to these ground rules, let me know and I'll remove your tree
from participation in linux-next.

The patches in my next queue are fully reviewed and (should) have seen
at least basic testing. The additional QA on top is just normal
regression testing and about every 2 weeks a manual testing cycle for
things like hotplug on the bazillion configurations we support (since
that takes our QA team about 1 week to complete we can't do higher
frequency there). The reason we've put that next queue buffer into
place was that before the pulls to Dave received essentially 0 testing
from our QA, resulting in lots more regressions slipping through.
-next-queued is also what I run here on all my machines and what patch
development is usually based on for drm/i915.

Does that put your concerns at ease?

Thanks, I'll subscribe to linux-next then.
