(This is a v2 of patch "drm/nouveau/disp/nv50: Add PFB writes")
This fix a GPU lockup on 9400M (NVAC) when using acceleration, see
https://bugs.freedesktop.org/show_bug.cgi?id=27501
v2:
- Move code to subdev/fb/nv50.c as suggested by Roy Spliet;
- Remove arbitrary writes to 100c18/100c24 as sugge

Dear All,
Please, never do pointless stuff like that.
I don't know what exactly are written in the "CEA guidelines"
mentioned in the above posts (AFAIK one cannot get a copy of them for
free legally), but no one should foll

Hi Dave,
It looks like you missed my last 3.18 pull from 9/24. This one
includes those patches and a few more on top. The additional patches are:
- Maarten's radeon fence updates
- Some additional debugging output

- Re-enable some dpm features that were previousl
Hi Dave,
Bunch of fixes for 3.18. Major parts:
- ppgtt fixes (but full ppgtt is for 3.19) from Chris, Michel, ...
- hdmi pixel replication fixes (Clint Taylor)
- leftover i830M patches from Ville
- small things all over
I'll be travelling the next two weeks (xdc&plumbers) but should be around
a f
Hi Dave,
Two leftover core patches for 3.18, Clint found one more troublesome hdmi
mode and some cleanup patch from Andrzej.
Cheers, Daniel

The NXP TDA998x HDMI transmitter may transmit audio to the HDMI link
from 2 different sources, I2S and S/PDIF.
This patch set adds an interface between the HDMI transmitter and
the HDMI CODEC.
The interface is used by the TDA998x driver to update the audio
constraints from the display characteris
This patch interfaces the HDMI transmitter with the audio system.

During system suspend after connector switch off its dpms field

The patch removes master PM callbacks as their functionality
is already duplicated by suspend/resume drm callbacks.

Implementing suspend/resume functionality in componentized drm drivers using
master component PM callbacks is problematic because those callbacks can be
called asynchronously regardless of existence/state of drm device.
The patch re-enables suspend/resume drm driver callbacks in drivers with
modese
Currently suspend and resume callbacks are called only if driver have
modeset feature disabled.
This patch moves the check directly to i915 driver, it will allow to
remove the check from the core in the future.

The main intent of this patchset is to allow use of suspend/resume drm driver
callbacks in KMS drivers, as these callbacks seems to me the best place
to implement suspend/resume functionality in drm driver.
Implementing this functionality in master component driver PM ops is problematic
as those ca
The audio constraints of the HDMI interface are defined by the EDID
which is sent by the connected device.
The HDMI transmitters may have one or many audio sources.
This patch adds two functions to the HDMI CODEC:
- it updates the audio constraints from the EDID,
- it gives the audio source type

Hi Linus,
Nothing too major or scary,
one i915 regression fix, nouveau has a tmds regression fix, along with a
regression fix for the runtime pm code for optimus laptops not restoring
the display hw correctly.
