I sent an email to oibaf, the ubuntu new oss drivers maintainer, and asked him if he could add those patches. This would make installation for all much easier.

Stay tuned. Finally big things are happening :-)

I stay tuned.
If you wish me to run tests on my development machine, that is the iMac, just let me know.
I'd be really happy to give my 10 cents.

So much from AMD so quickly, is all this due to the Steambox?

Fabio Pedretti (oibaf) was fast: https://launchpad.net/~oibaf/+archive/graphics-drivers/

So for general usage, all can be done via ppa:

Code:
sudo apt-add-repository ppa:oibaf/graphics-drivers

sudo apt-add-repository ppa:wsnipex/xbmc-xvba-testing

sudo apt-get update

sudo apt-get dist-upgrade

sudo apt-get install libg3dvl-mesa libvdpau1

Make sure to run at least 3.11.1 kernel with the addition of radeon.audio=1 and radeon.dpm=1 to the kernel command line.

If you want the 7.1 LPCM audio, make sure to install the kernel I linked above or build yourself with the two patches mentioned.

Edit: It is currently rebuilt - so wait some minutes: https://launchpad.net/~oibaf/+archive/gr...ld/5042388

Hey fritsch,
looking forward to try the OSS implemenatation this evening. Any advices for the video settings?

Artax · 2013-09-23, 13:12

Hi all, I'm following with excitement the latest updates, great work!!!

I have a HTPC based upon an AMD E-350 and I would like to help testing these new releases, but without replacing my working Frodo-based installation.
I was thinking about an installation on a USB stick: ubuntu (12.04, 13.04, 13.10?), plus some ppa repo, what do you think? What do you suggest?

ryszardzonk · 2013-09-23, 13:16

Sort answer - It works great Smile

Long answer
Besides following all the above directions one should also set <usevdpaumixer> to TRUE otherwise video will look plain ugly without it with all the rough edges.

There are also two others that I have disabled. I am not to sure as of what they do or should I enable them too
<vdpauUpscalingLevel>false</vdpauUpscalingLevel>
<vdpau_allow_xrandr>false</vdpau_allow_xrandr>

On high bitrate content [details below] I saw on one of my videos that it works perfectly and then all the sudden playback will pause with video being buffered, reports of of V/A out of sync errors until it gets buffered back again then errors will quickly disappear. I do not know reason for the buffering as this is local video on SSD drive and CPU use does not ever go over 25% on any of the two cores. Later on I will check if it has any thing to do with this modeline I introduced from here for 24p videos http://paste.ubuntu.com/6142741/

Yeah - i am really happy with all of it. A little to go, that the Interop can also go into mesa.

Btw. there is no need to build external ffmpeg. Fernetmentas master git has all that is needed, including the referenced patch in this forum.

nichiren · 2013-09-23, 19:40

I've also been waiting for flawless driver from AMD for two years now, and as there doesn't seem to be one coming in the near future and there being now a viable alternative in the OSS driver I decided to take a leap of faith with it.

So, for the background, I begun with system originally installed from some XBMCbuntu with added PPA wsnipex/xbmc-xvba-frodo (used to be wsnipex/xbmc-xvba until Frodo specific one was created), running on AMD A8-3850 based hardware connected via HDMI to a Panasonic TV. Audio output is straight 2.0 HDMI to the TV. I control the setup with the TV remote (CEC through Pulse-Eight USB-CEC adapter) and an iMON infrared remote.

These are the steps I took, not necessarily in this exact order though:

Purged Catalyst
Installed 3.11.1 kernel from http://kernel.ubuntu.com/~kernel-ppa/mai...1.1-saucy/, no patches mentioned by fritsch
Added radeon.dpm=1 radeon.audio=1 to grub defaults
Replaced wsnipex/xbmc-xvba-frodo with xbmc-xvba-testing
Added PPA oibaf/graphics-drivers
apt-get update && dist-upgrade
Installed xserver-xorg-video-radeon and vdpauinfo
Adjusted xorg.conf for the driver change
Disabled XvBA and enabled VDPAU

Now, I had mostly usable system as expected, by my brief testing I've concluded that almost everything appears to work at least as good as earlier with Frodo + XvBA + fglrx. Almost everything.

Key presses from either of the remote controller randomly trigger a double action, this did not occur before.

Then, there is something strange that appears to concern video modes and audio. From what I tested, videos with 25.000 frame rate seem to work, except that it seems to use the default 50 frame mode. This doesn't seem to cause any problems and I'm not quite sure if it worked any different earlier, so not really a problem.

But 23.976 frame rate videos switch the video mode to an actual 23.976 mode. And while playing a video in this mode, whenever there is enough loudness in the sound, there is a clear and regular 'clicking' sound mixed in. This is not audible in silent or near silent parts, only when there is actual sound in the video. If I disable 'Adjust display refresh rate to match video' option, the video mode no longer changes from default 50 refresh rate and the clicking doesn't appear any more on videos it does when rate adjust is enabled. I also tried manually setting the video mode to 23.976 during playback with rate adjust disabled and video playing at default 50 and the clicking started.

Settings I use are:

Vertical blank sync - Always enabled
Adjust display refresh rate to match video - Always
Sync playback to display - Enabled
A/V sync method - Video clock (Drop/dupe audio)

None of the other settings seem to affect the clicking.
I briefly tested some video files I knew to be working to rule out a corrupted file causing it, I'll get a debug log tomorrow if I have time. Much too tired to think at the moment.

Anyway, other than those, and some wildly fluctuating fps while in the menu causing occasional stutters (related to double key actions?), the system appears to work fine.
Bye bye, Catalyst Cool

**deadite66** · 2013-09-23, 19:59

i get the clicking too with 'Adjust display refresh rate to match video' enabled.

**fritsch** · 2013-09-23, 20:05

I told that before - that was the patch, that is to be reverted :-)

Redfoox · 2013-09-23, 20:15

Hi I cannot get it working properly Sad

.
when I run:

Code:
dmesg | egrep 'drm|radeon'

I get the following error:

Code:
drm: module verification failed: signature and/or required key missing - tainting kernel

Is there something I did wrong or forgotten?

**fritsch** · 2013-09-23, 20:28

You just have fglrx installed

btw. next time: complete dmesg or none ;-)

Redfoox · 2013-09-23, 20:33

True but I uninstalled that one.

Is this better?
