Ubuntu Precise 12.04 - TI OMAP Release PPA Update October 2012 Boudet, Xavier 10/3/12 6:07 AM
Hi there,

A major update has been done on TI PPA. Please read the below e-mail especially for upgrade.
If you do not have installed the TI release PPA, please refer to New installation procedure.

New installation procedure:
  1- Add TI OMAP release PPA:
    $ sudo su -
    # export http_proxy=<your proxy if any>
    # export https_proxy=<your proxy if any>
    # add-apt-repository ppa:tiomap-dev/release
  2- Perform the upgrade:
    $ sudo apt-get update
    $ sudo apt-get dist-upgrade
    $ sudo apt-get install ubuntu-omap4-extras
  3- You can re-run a dist-upgrade for safety at the end, then reboot

Update procedure:
1- Perform the upgrade:
    $ sudo apt-get update
    $ sudo apt-get dist-upgrade


Post Installation Important Information:
* after the installation/update, it is advised to log as default user and to execute:
    # On Panda 4430: 
    $ /usr/bin/alsaucm -c Panda set _verb HiFi 
    # On PandaES 4460: 
    $ /usr/bin/alsaucm -c PandaES set _verb HiFi

* You need to force installation of new bootloaders (if any) through command:
    $ sudo /usr/sbin/flash-kernel --update-bootloader

* It is advised to use Ubuntu 2D instead of Ubuntu (3D) default UI. Nevertheless, main compiz issues have been fixed.

* In some cases, you might need to re-install dkms packages: after reboot,  check if omapdrm_pvr module is loaded, if not execute following command before to reboot:
    $ sudo apt-get install --reinstall pvr-omap4-dkms

New/Fixed in October 2012 release:
 * Kernel bug fixes:
- Rebase on Linux 3.4.11
- Panda DVI connector support
- DSS off mode support
 * Memory leaks during playback fixed
 * Decoder issues fixed
 * GBM/KMS support - Wayland DDK libs delivered.
 * Dual screen support on HDMI and DVI: you need to disable HWcursor in xorg.conf file, please edit /usr/share/X11/xorg.conf.d/99-omap.conf and add in section Device:
Option "HWcursor" "false"

Playing with GBM/KMS:
You just need to install following packages:
$ sudo apt-get install libwayland0 libgbm1

You can test now the kmscube test apps:
$ git clone git://github.com/robclark/kmscube.git

go into kmscube dir:
$ sudo apt-get install autoconf autotools-dev libtool libdrm-dev libwayland-dev libgbm-dev ubuntu-omap4-extras-graphics-dev
$ ./autogen.sh
$ make


Reboot with text in command line or stop lightdm with "sudo service lightdm stop"
If you have booted with text in bootargs, first execute "sudo pvrsrvinit", then execute:
$ sudo ./kmscube

Known Issues:
* BT is not supported - shall be fixed next month.
* Black screen issue on some HW - workaround: Ctrl+Alt+F1 then Ctrl+Alt+F7 or boot with screen un-plugged, plug it after 1 minute. Issue under investigation.

Support:
updates for bug fixes in the PPA, so make sure to keep your system up-to-date!


Reference/Reminder:

The 'top-level' ubuntu-omap-extras will install the following packages:
 - ubuntu-omap-extras-multimedia: another meta package that installs all the requires packages for MM use case:
   * GST, a modified version still compatible with all Ubuntu apps such as totem
   * gst-ducati and libDCE the main components that bring MM h/w acceleration into the system
 - ubuntu-omap-extras-graphics: meta package that pulls in all GFX components including new X11 driver (binary blob) and SGX kernel module (source using DKMS to build)
 - ubuntu-omap-extras-config: some config scripts to set some permission issues, and to ensure that the Ducati firmware is loaded at boot time by upstart.

This release comes with the following major changes:
 - DCE interface for the h/w accelerated codecs - already there in 11.10
 - migration to rpmsg driver (aka syslink3, see http://lwn.net/Articles/448562/ and http://omappedia.org/wiki/Category:RPMsg)
 - DRI2 extension for Video support (http://www.phoronix.com/scan.php?page=news_item&px=OTgxOQ)
 - migration to a new open source X11 driver for OMAP (http://cgit.freedesktop.org/xorg/driver/xf86-video-omap/ )
 - a new GST video-sink: dri2videosink to display video through the SGX (instead of v4l2sink). For more information, see https://wiki.linaro.org/OfficeofCTO/MemoryManagement?action=AttachFile&do=view&target=linux-video.pdf
 - Linux 3.4 kernel, Ubuntu kernel will be replaced. This kernel is largely based of Linaro kernel, and sources are available here: http://dev.omapzoom.org/?p=integration/kernel-ubuntu.git. Linux-image-<version> package version correspond to a tag ti-ubuntu-<kernel version>  in this tree.
 - ...

One important remark concerning bootargs when upgrading to TI kernel:
Please replace "vram=40M mem=456M@0x80000000 mem=512M@0xA0000000" or any vram or split mem settings with: "mem=1G@0x80000000"

We advise following bootargs:
ro elevator=noop console=ttyO2,115200n8 mem=1G@0x80000000 root=<UUID or LABEL root> fixrtc splash

Please update your /boot/boot.script file then run flash-kernel to apply the changes.

Xavier, if you want any help with this I can repeat the problem with every boot. Just give me some test cases and I'll give it a blast!

Hi Xavier,

After PPA upgrade pvrvideosink still not working for pandaboards rev A3   (for boards rev A4 seems to be working fine).

Why don't you use dri2videosink? Nevertheless, pvrvideosink is still supported.
I have a rev A3 board that works fine with both.

Can you share the output of:
DISPLAY=:0 GST_DEBUG=*:2,ducati*:5 gst-launch-0.10 playbin2 uri=file:///home/jjcgp0/Videos/MPEG4_VGA_AAC_HE.3gp video-sink="pvrvideosink"
And:
DISPLAY=:0 GST_DEBUG=*:2,ducati*:5 gst-launch-0.10 playbin2 uri=file:///home/jjcgp0/Videos/MPEG4_VGA_AAC_HE.3gp video-sink="dri2videosink"

Can you check also that omapdrm_pvr module is loaded, if not do not hesitate to reinstall the dkms package to fix the issue:
sudo apt-get install --reinstall pvr-omap4-dkms

When you say "for boards rev A4 seems to be working fine" are you using same Filesystem on e.g. same SD card exactly?

Xavier Boudet

Hi Xavier

Yes, I am using the same Filesystem (same SD card) on both boards.

I don't have the File system right now but I will send you some GST logs shortly.

Best regards
Joaquin

Hi,

Can you please execute on the media file you have been using:
$ DISPLAY=:0 gst-discoverer-0.10 <media file>

Can you also execute the following to have main package version:
$ dpkg -l | grep -e gst -e linux-image -e pvr -e dce

Please send back the output.

Hi Xavier,

I have found another memory leak, maybe you have the possibility to look in to that. I run a looped video on the pandaboard (ES) with this command:
gst-launch-0.10 --loop playbin2 video-sink="dri2videosink" uri=file://<movie>.mov &

After running for 2 days the video stops. This was with the August update, but now after trying the latest October update, the problem persists.

Restarting the video shows a memory issue:

Hello Juergen,

This is a known issue, the pvr dkms module is not able to build vs the "default" kernel.
Nevertheless, it compiles fine with the new kernel installed with omap4-extras.
So you can ignore this warning and if you are happy with the new kernel/ppa then un-install previous linux-image and associated linux-headers to prevent having this error again.

Hello Linus,

We have indeed few remaining memory leaks that can lead to crashes in some cases.
We shall have an update begin of November improving the situation.
Can you please try to disable "ondemand" to see if disabling ondemand reduce the probability?

Edit file: /etc/init.d/ondemand
Comment line:
        echo -n ondemand > $CPUFREQ

Can you also share the gst pipeline your are using and some info on the video you are using.
Please send output of command: gst-discoverer-0.10 <sample file>

Can you also confirm if both filesystem and samples are on the SD Card?
I would suggest to have at least sample on USB drive.
I would also advise to setup filesystem on USB drive for better performance.

Hi Xavier,

I am new to here.

I have successfully install the update and confirm the video H/W acceleration is working.

But the system would crash when I try to play a MPEG-2 ( Full-HD ) file that has more than 2 min length.

I am using openbox as window-manager, gst-lauch to play the video, the MPEG-2 file is located inside the SD-card.

And I have disabled the swap area.

Here is my crash log from serial terminal:

Hello

First of all, please check that you are using Ubuntu2D and not Ubuntu desktop that uses compiz.

Mouse cursor flash is consequence of HWcursor, you can fix that by disabling HWcursor in xorg.conf file, edit file /usr/share/X11/xorg.conf.d/99-omap.conf and add the bold line:
Section "Device"
    Identifier    "Video Device"
    Driver         "omap"
    Option        "Debug"        "false"
    Option        "HWcursor"        "false"
EndSection

I suppose that you are using filesystem on SD card, I would advise to switch to a USB drive:
http://omappedia.org/wiki/Ubuntu_on_OMAP_FAQ#I_want_to_install_Ubuntu_on_external_USB_hard_disk_instead_of_sluggish_SD_card

Freeze and startup issue are surprising nevertheless.
Are you sure that the omapdrm_pvr module is loaded?

Re: [pandaboard] Re: Ubuntu Precise 12.04 - TI OMAP Release PPA Update October 2012 Xavier Boudet 10/17/12 9:34 AM
On more point, can you also check your bootargs, with new kernel you need something like:
ro elevator=noop console=ttyO2,115200n8 mem=1G@0x80000000 root=<your root>
Be sure not to use anymore vram=xxx.
If not, please update /boot/boot.script, then execute "sudo flash-kernel" then reboot.

Re: Ubuntu Precise 12.04 - TI OMAP Release PPA Update October 2012 Xavier Boudet 10/18/12 12:34 AM
Hi,
I have checked the question you posted.

Can you check/confirm the following:

1- Bootloaders:
Which version is displayed for u-boot when booting?
You shall have:
U-Boot 2012.04.01 (Jul 19 2012 - 17:37:11)

If this is not the case, ensure the you have the correct u-boot package installed:
$ dpkg -l | grep u-boot-linaro-omap4-panda
ii  u-boot-linaro-omap4-panda              2012.04.2+6514+45+201207191704~precise1 U-Boot bootloader binary for the TI OMAP4 Panda board

Then execute:
$ sudo /usr/sbin/flash-kernel --update-bootloader

2- Bootargs:
Can you ensure that your bootargs are aligned with the following:
ro elevator=noop console=ttyO2,115200n8 mem=1G@0x80000000 root=<your root> fixrtc splash

Please update /boot/boot.script accordingly, then you can use "flash-kernel" to update your boot.scr in boot partition.

=======

Then concerning the traces you have reported on askubuntu, the kernel traces are "normal" and can be ignored.
Then, if you are still having issues, can you please execute command: "sudo omap-collect-info" after a freeze (except if the freeze never ends then do it after a successful boot...). Then please send me the generated tarball (to me only).

Regards, Xavier Boudet

Hello,

I am having the same trouble with my pandaboard ES freezing very often and having troubles rebooting or starting up. I explained my trouble here but didn't get any reply so far.
Reading the comments below, I checked if omapdrm_pvr is loaded. Running lsmod show me this:
Module                  Size  Used by
omapdrm_pvr           336605  0 

The board freezes when I am either downloading and transferring files (180+ Mo) or when I install packages.


I also had the mouse flashing problem but this is solved by disabling HWcursor ;).


Cheers!

My G-streamer command is :

gst-lauch-0.10 playbin2 uri=<path_to_MPEG-2_file>

I haven't mastered all the pipeline commands yet.

One little thing is, I am using the SanDisk Extreme Pro 8GB( 95MB/s ), could this SD-card would have the best
performance or a USB drive is still the best?

Can you also share the gst pipeline your are using and some info on the video you are using.
Please send output of command: gst-discoverer-0.10 <sample file>

Can you also confirm if both filesystem and samples are on the SD Card?
I would suggest to have at least sample on USB drive.
I would also advise to setup filesystem on USB drive for better performance.

Hi Xavier,

I have successfully install the update and confirm the video H/W acceleration is working.

But the system would crash when I try to play a MPEG-2 ( Full-HD ) file that has more than 2 min length.

I am using openbox as window-manager, gst-lauch to play the video, the MPEG-2 file is located inside the SD-card.

And I have disabled the swap area.

Here is my crash log from serial terminal:

I doubt this is related to anything in TI PPA.. I don't think we
include any qt in our PPA.

However unity-2d does use qt.. I don't know really about qt-sdk but
perhaps it is an incompatible version of qt.  If possible, try
installing qt-sdk in some location other than /usr... ie, if you use
/usr/local/qt or something like this, then it won't conflict with the
versions that unity-2d uses.  Or alternatively install openbox or some
desktop that does not use qt.

i suspect the pre-built DDK samples are built for soft-float ABI, not
hard float. see

so yes you need to rebuild, but not because of kernel version, but ABI.

you should be able to recompile the IMG DDK samples from sources, but
for a quick test, we provide a simple test app in pvr-omap4-utils,
called /usr/bin/xgles2test1 which displays some 'spinning
triangles'...

the other option is to run kmscube, which would use gles but not X11.

Hi,

I tried installing the ppa updates on Pandaboard ES by following your instructions. But after doing so, Ubuntu won't boot at all. I tried it 4-5 times using different SD cards but still no luck. Everything works fine though before installing the ppa upates. 

Here is my logfile:

Here are my bootargs.

I would really appreciate if someone would help me solve this problem.

Cheers,
Jayneil.

There is a special kernel needed, as some of the display updates
needed to make weston work (and also fix mouse issues w/ compiz) are
not in the release ppa.. see:

Hi ndec,

I have built the example (using the supplied make script) and still fail to run them on my pandaboard:

You are clearly using "aeabi". I suppose you are cross compiling, please use armhf cross compiler and that you have "-mfloat-abi=hard" in your CFLAGS (and not "-mfloat-abi=softfp")

I have executed the test application you suggested and saw for a glance the triangle:

Does this mean the TI DDK for SGX is installed and configured correctly in my system?
Yes, DDK is correctly installed.
Can you please point me to the exact location (on the target) of the graphics library mentioned in Imagination SDK user guide?
DDK libs are in /usr/lib, you can have the list of SGX packages with "dpkg -l | grep SGX".

I will try next to run kmscube.
Again, thank you for your help.

Hi, 

I am using pandaboard Rev A4.
I managed to enable HW decoding but erased my SD card and wanted to do it again. Now it is now working.
I followed user issues and your answer but can not have it working...

According to the package versions, you are not using TI OMAP Release PPA.
Did you enabled a linaro-maintainers PPA?

Hi,
Thanks for your answer. Your were right, I was missing some packages... 
It is now working right.

I still see some artifcats while playing H264 in 1080p. I was using the following command :

gst-launch filesrc location=/home/user/sample.mp4 ! qtdemux ! h264parse ! ducatih264dec !  pvrvideosink

But for sure it is much more better than using FFmpeg decoding.

I tried also to read RTSP streams on a pandaboard from my local rtsp server using this command:

gst-launch-0.10 -v rtspsrc location=192.168.50.113 name=t ! queue ! gstrtpjitterbuffer latency=1000 ! ducatih264dec !  pvrvideosink

Lot of frame must be dropped despite a good ethernet connection. 

Do you know how we could optimize it ?

Eloi

Hello,

You need to use "dri2videosink", pvrvideosink is still supported but dri2 is preferred.

Why don't you use playbin2 for pipelines?
