[Zhi Wang]

Sorry it's gvt-next, so it should be for 4.18.

Thanks,

This reverts a commit in v4.15. Why is it in a -next pull and not a
-fixes pull?

It also conflicts, please advise how to resolve:

This one was originally queued for 4.17 in gvt-next-fixes, but declined as
Joonas thought this is new feature as enabling vGPU priority scheduling,

Re: [PULL] gvt-next for 4.17

[Zhi Wang]

Thanks, Let me discuss with Zhenyu about how to deal with this. It must 
be the git rebase I've done which causes the commiter change without new 
signoff-by.

Thanks,
Zhi.

Weird. I try to apply the patches one by one on

Re: [PULL] gvt-next for 4.18

[Zhi Wang]

Hi Jani:

I picked out the patch which causes conflicts and may put it back in the 
next back merge from drm-intel-next to gvt-next. So there shouldn't be 
any conflict in this pull. Thanks for your efforts.

Thanks,
Zhi.

Thanks, pulled to drm-intel-next-queued.

Just as a reminder, if you have more stuff for v4.18 the deadline is in
about three weeks.

The patch which causes conflict:

From: Weinan Li <weinan.z.li@intel.com>
Date: Wed, 21 Mar 2018 15:40:32 +0800
Subject: [PATCH] Revert "drm/i915/gvt: set max priority for gvt context"

This reverts commit 11474e9091cf2002e948647fd9f63a7f027e488a.

There are issues which will block the host preemption before, instead of
disabling it use one workaround "setting max priority for gvt context"
to avoid the gvt context be preempted by the host. Now the issues have been
cleared, so revert this patch to enable host preemption.

v2:
- refine description(Zhenyu)

Author: Chris Wilson <chris@chris-wilson.co.uk>
Date:   Wed Apr 18 19:40:52 2018 +0100

     drm/i915: Pack params to engine->schedule() into a struct

     Today we only want to pass along the priority to 
engine->schedule(), but
     in the future we want to have much more control over the various 
aspects
     of the GPU during a context's execution, for example controlling the
     frequency allowed. As we need an ever growing number of parameters for
     scheduling, move those into a struct for convenience.

     v2: Move the anonymous struct into its own function for legibility and
     ye olde gcc.

I found it in drm-tip. Looks I have to send another pull request when 
the patch above is in a new drm-intel-next tag.

Thanks for everyone's efforts.

Thanks,

Pulled, thanks.

Please try to avoid rebases; it looks like you're now the committer for
each commit but without Signed-off-by.

As discussed in IRC, the gvt-next PR was as --in-reply-to for this
message, so I indeed confused it for being discussion about the gvt-next
between Jani and Zhi, and missed it :(

So this missed v4.17. I've now pulled this into drm-intel-next-fixes,
and it'll get merged upstream for v4.18. If you need the commits
backported, you'll need to make stable backport requests to the stable
team after the commits have been merged to Linus' master.

BR,
Jani.

As discussed in the IRC, it got merged. Only in the final pull request
generation I'll summarize all the intermediate tags.

Joonas, so did this miss the deadline for v4.17? You're not making
another pull request?

[PULL] gvt-next for 4.17

[Zhenyu Wang]

[-- Attachment #1.1: Type: text/plain, Size: 4339 bytes --]


Hi,

Here's gvt-next update for 4.17. Biggest update is for huge code
refactor of shadow ppgtt from Changbin which is the most obscured
part, and with KBL context save/restore improvement from Weinan,
with other fixes.

Thanks.
