DP mst audio support missed 4.10 over here on the drm side. And I
wasn't aware that we need a topic branch for it, so I just smashed it
into our drm-intel-next queue ... I can send you the most recent
stable tag for that, but that's heading in only for 4.11.

It's fine, we can postpone to 4.11 as well.  I just thought it were
already queued for 4.10.

If so, I'm going to queue these patches once after 4.10-rc1 is
released.

Re: [alsa-devel] [PATCH v4 0/3] support DP MST audio

[Yang, Libin]

Hi Takashi,

It seems the patches for DP MST in gfx is not merged into Linus branch.

Do we have plan to merge gfx branch manually and review the patches for audio? Or we will wait the DP MST patches for i915 merged into Linus branch?

Regards,
Libin

Sorry, this was delayed due to the vacation.
Now I applied these three patches to topic/hda-dp-mst branch based on
4.10-rc2, and it was merged to for-next branch.

  git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound.git topic/hda-dp-mst

Daniel, Jani, if you guys need to merge to i915 tree, feel free to
pull from that branch.


thanks,

Takashi

Thanks. These audio patches are based on the i915 dp mst patches. Without
I915 driver patches support, it will make errors.

Ah yeah, I forgot it.  So I removed it from for-next branch, but
topic/hda-dp-mst branch is kept so that it can be merged to i915
tree.

Let me know if there is any i915 branch I can pull into sound tree.

Aw, I didn't know that the depency goes this way round, the dp mst
patches (I'm not even sure which ones they are) on the i915 are just
on the general pile. So not anywhere near a place where I can make a
topic branch.

I guess what needs to be done now is a cherry-picked list of just the
patches we need, on top of -rc3, that I can then pull into
drm-intel.git plus send a pull request for that to Takashi. That means
the patches are twice in drm-intel.git, but if we cherry-pick
reference them correctly then that should be all ok and can't really
be helped.

Or we just delay the audio side for 4.12, dp mst audio support is 4
years late anyway, so one more release won'thurt that much ;-)

Well, thinking of the amount of patches, I guess we can do other way
round: basically it's fine to apply Libin's latest patches to drm tree
for 4.11, if it makes things easier.  I don't think we'll have a big
conflict with these changes for others during 4.11 development.  If
any, I can pull some of stable point from drm tree.

Does it work for you?  If yes, feel free to apply these three sound
patches to drm or i915 tree with my ack.

Works for me too. Libin, can you pls resend (somehow this thread
disconnected from the patches for me), with Takashi's r-b + ack for
merging through drm-intel?

Re: [alsa-devel] [PATCH v4 0/3] support DP MST audio

[Yang, Libin]

Hi Daniel,

OK, I will resend the patches tomorrow. Thanks.

Hi Takashi,

In case you still need the patches for i915, it is on
git://anongit.freedesktop.org/drm-tip:drm-tip

My patches are:

commit 9a148a96fc3a654ddcf142a7ab7db37b972ba5d8
drm/i915/debugfs: add dp mst info

commit 9935f7fa2854355203e3976762eecfb218079aac
drm/i915: abstract ddi being audio enabled

commit 7f9e77545b92bcb894b8e2be5646535e8ba8da9e
drm/i915: enable dp mst audio

commit 31613268c0a6f7abdb0c19487a084249bcf203ba
drm/i915/audio: extend get_saved_enc() to support more scenarios

commit f55d23be11ed15f493957246f3b81fc530e79d70
drm/i915/audio: extend audio sync rate support for DP MST

And you may still need the patches in gfx to fix the flicker issue, which Dhinakaran
can help.

Regards,
Libin
