Last Updated: 30/08/2013 - wayland and other updates
11/11/2013 - xbmc 13 gotham
14/09/2013 - (temporary) sound fix

A DASHBOARD thread for the XU with experiences and fixes.

OS: Ubuntu 14.04 Dev Center viewtopic.php?f=61&t=4073 | Debian jessie (testing)
Currently need to choose between running EGL-accelerated libhybris with Android hwcomposer, or X11 non-accelerated with Linux hwcomposer.

Kernels:

• 3.4.103 cloned git repository from https://github.com/hardkernel/linux/tree/odroidxu-3.4.y, pull and compile from time to time, howto at viewtopic.php?f=52&t=81
• kernel config: http://pastebin.com/KtSerVWa/

PowerVR acceleration:

• no linux kernel drivers, none will be developed
• current solution involves the use of Android drivers + libhybris

XBMC 13 gotham:

• See below viewtopic.php?f=62&t=2176#p22107

Sound:

• fix for ALSA/PULSE below: viewtopic.php?f=62&t=2176&p=16671#p16671

Wayland:

• see below: viewtopic.php?f=62&t=2176&p=50530#p50530

This is EGL accelerated Wayland:

Sound fix for the XU linux images:

0) running pulseaudio as root
====================
in /etc/inittab add:

Code: Select all

pa:345:respawn:/usr/bin/sudo /usr/bin/pulseaudio --disallow-exit --disallow-module-loading=1 --log-target=syslog --high-priority


1) ALSA
====================
you can try using one of following /etc/asound.conf files:

Code: Select all

pcm.!default {
   type rate
   slave {
      pcm "plughw:0,0"
      rate 44100
   }
}


Code: Select all

pcm.!default {
   type plug
   slave.pcm "dmixer"
}

pcm.dmixer  {
    type dmix
    ipc_key 1024
    slave {
      pcm "hw:0,0"
      period_time 0
      period_size 1024
      buffer_size 4096
      channels 2
      rate 44100
   }
   bindings {
      0 0
      1 1
   }
}

ctl.dmixer {
   type hw
   card 0
}


Code: Select all

pcm.!default {
        type hw
        card 0
}

ctl.!default {
        type hw
        card 0
}


Code: Select all

pcm.pulse {
    type pulse
}

ctl.pulse {
    type pulse
}

pcm.!default {
    type pulse
}

ctl.!default {
    type pulse
}


I can confirm the first fix works.

2) PULSE
====================
Because of the different driver code being used, pulse audio fails with the following error:

Code: Select all

[   17.854442] dma-pl330 dma-pl330.0: pl330_submit_req:1677 Trying increasing mcbufsz
[   17.860599] dma-pl330 dma-pl330.0: fill_queue:2383 Bad Desc(3)


This is just a temporary fix, since performance is not as good with this. Edit /etc/pulse/default.pa and add tsched=0 to the udev module:

Code: Select all

### Automatically load driver modules depending on the hardware available
.ifexists module-udev-detect.so
load-module module-udev-detect tsched=0
.else
### Use the static hardware detection module (for systems that lack udev support)
load-module module-detect
.endif


Now pulse audio should work as well

3) Permissions errors on boot with pulseaudio installed
====================

Code: Select all

This happens because ALSA is trying to restore sound levels, but it should be pulseaudio that does that.
The fix is to edit /etc/init.d/alsa-utils and modify restore_levels() function to return 0:

Code: Select all

restore_levels()
{
        # we are using pulseaudio, and do not restore levels here, so we return 0
        return 0

        [ -f /var/lib/alsa/asound.state ] || return 1
        CARD="$1"
...

Excellent tutorial on sound. I have sound working now and that is a real bonus!

The kernel sources contain a new uboot.bin but there is no info in the commit about what has changed nor how to update uboot on the XU.
A little help with that would be much appreciated. Also we might benefit form adding all the know-how from this forum to the wiki for the XU.

New u-boot as just a small modification to increase the buffer size of the u-boot variables..

How to install hardware accelerated XBMC.
Code on http://github.com/mihailescu2m/xbmc branch Gotham-mfc-XU (Gotham 13.2 final).

0) compiled kernel with Android logs and binder support

1) copied the /system folder from existing images; link /vendor to /system/vendor (available as a separate download in the forums)
current version is for Android 4.2.2; ongoing work for Android 4.4.4
copy Android 4.4.2 headers from download/file.php?id=1227 to /usr/local/include

2) cloned libhybris repository. compiled the stuff in the "hybris" folder: (add --enable-wayland --enable-mesa for wayland)

Code: Select all

# ./autogen.sh --enable-arch=arm --with-default-hybris-ld-library-path=/system/lib:/vendor/lib --with-android-headers=/usr/local/include/android

------------------------------------------------------------------------
libhybris 0.1.0
------------------------------------------------------------------------
Configuration Options:
  debug build.............: no
  trace...................: no
  prefix..................: /usr/local
  arch  ..................: arm
  headers path ...........:
  default egl platform ...: null
  default ld_library_path.: /system/lib:/vendor/lib

Now type 'make' to compile and 'make install' to install this package.


2a) run ldconfig to update library path to use hybris instead of mesa

3) compile xbmc gotham. repository at http://github.com/mihailescu2m/xbmc branch Gotham-mfc-XU. xbmc configure flags are:

Code: Select all

./configure --enable-codec=mfc --enable-libcec --disable-x11 --enable-alsa --disable-pulse --enable-neon --disable-debug --enable-optimizations --enable-ccache --enable-gles --enable-non-free --disable-gl --disable-vdpau --disable-vaapi --disable-crystalhd --disable-openmax --disable-joystick --disable-rsxs --disable-projectm --disable-fishbmc -enable-texturepacker --with-platform=hybris --with-cpu=cortex-a15 FFMPEG_CFLAGS="-mfloat-abi=hard -mfpu=neon -ftree-vectorize -mvectorize-with-neon-quad -ffast-math -mcpu=cortex-a15 -mtune=cortex-a15 -O3 -pipe -fstack-protector" CFLAGS="-mfloat-abi=hard -mfpu=neon -ftree-vectorize -mvectorize-with-neon-quad -ffast-math -mcpu=cortex-a15 -mtune=cortex-a15 -O3 -pipe -fstack-protector -DTARGET_HYBRIS=1 -I/usr/local/include/hybris" CXXFLAGS="-mfloat-abi=hard -mfpu=neon -ftree-vectorize -mvectorize-with-neon-quad -ffast-math -mcpu=cortex-a15 -mtune=cortex-a15 -O3 -pipe -fstack-protector -DTARGET_HYBRIS=1 -I/usr/local/include/hybris"


make and install

4) add the following startup script (/etc/rc.local for example):

Code: Select all

rm -rf /dev/log
rm -rf /dev/graphics
mkdir /dev/log
mkdir /dev/graphics
ln -s /dev/log_events /dev/log/events
ln -s /dev/log_main /dev/log/main
ln -s /dev/log_system /dev/log/system
ln -s /dev/log_radio /dev/log/radio
ln -s /dev/fb0 /dev/graphics/fb0

/vendor/bin/pvrsrvctl --start --no-module || true

/system/bin/servicemanager &
/system/bin/mediaserver &


5) disable (linux) exynos5-hwcomposer from starting at boot.

Some notes:

* 60fps GUI in 1080p resolution with Ace skin ... that's double the fps from the U2/3...
* X and XBMC do not work at the same time... X needs exynos5-hwcomposer, which breaks xbmc... so if you want to switch between them you need to start/stop exynos5-hwcomposer manually...
* same source can be used with --enable-wayland; no more platform=hybris needed

I have been looking through ARM documentation but it seems that the rev 2 p3 of the XU does not have the specific errata selected in the kernel build.
I tested some kernels with the errata turned off for the loop buffer and it runs fine. (the Chromebook won't be able to compile kernels and have many weird errors with loop buffer enabled.)

Can you detail more? I'm able to compile kernels with several gcc versions without issues on XU

[janrinze]

Did you check the kernel config?

[mdrjr]

Did you check the kernel config?

Yep.. but I'm still wait for more details.. such as what to check.. how to test...

[SevenW]

Would this approach to xbmc then work with different linux distributions?
Will it also work with the 3.4.67 kernel? Or is there an incompatibility with the hwcomposer in /system folder?

It will work, all you need to add is some Android bits that are disabled.

[janrinze]

mdrjr: ERRATA 773022 and 774769.

[mdrjr]

mdrjr: ERRATA 773022 and 774769.

I'm aware of those ERRATA's what I don't get is that if we are affected or not.. As far as I know we aren't affected by that.. Samsung should had it fixed in silicon..

[janrinze]

It should be fixed.. so why are they selected in the kernel?

[mdrjr]

Don't know.. test without.. if no issues, submit a PR

[janrinze]

It looks like the code checks for the version of the chip. if it is not the affected one it skips the errata. Still makes me wonder why it looks like the loop buffer is disabled.
With loop buffer enabled the chromebook has double bogomips value. The bogomips value on the XU is seems to indicate loop buffer is disabled. Could this have been disabled in the bootloader?

[mdrjr]

keep in mind that when XU boots it boots with the A7's cores. Not the A15's. So initial bogomips might be slightly low..

[janrinze]

The kernel states revisions up to r0p4 but ARM has no r0p4 but it does have r4p0 so it seems all revisions have this bug?
Odroid XU has r2p3. It gets me confused. Do you know which errata do apply to our chip revision?

[gripped]

Just an informational post

If compiling xbmc with libhybris decoding instead of mfc you need this file in /etc

media_codecs.xml

(4.59 KiB) Downloaded 238 times

Or the decoder won't start and xbmc falls back to software decoding

[memeka]

Well I've built everything with: --prefix=/usr/local and PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:/usr/lib/pkgconfig set.
Also I have a file /etc/ld.so.conf.d/hybris.conf with: /usr/local/lib
That way configure scripts will look in /usr/local first and the linker will always search in /usr/local/lib first.

Btw if you have any mesa-*-dev packages installed then remove those first.
Hybris provides the required headers with: --enable-mesa.

Then from Weston, I just run /usr/local/lib/xbmc/xbmc.bin and it works.
It's butterly smooth and doesn't flicker.
Only bug in XBMC is that it freezes when I try to close it, but that happens on the hwcomposer build as well

I guess if anyone can fix the XBMC closing issue, we can build the Hawaii or Enlightment desktop with Chromium browser.
Then we'll have an accelerated desktop with a browser and media player
Or you can upgrade to the latest Ubuntu beta and give the Mir display server a try, it features a hwcomposer backend so you don't need run Qtwayland for it
Unfortunately gnome-shell still requires a drm/kms driver for output so that won't work for now.

EDIT: I've attached the headers for libhybris.
I think you need to rebuild the qt5-qpa-hwcomposer, libhybris and weston using these.

+ QT5-hwcomposer plugin fix for QT5.3.1: https://github.com/aosp-hybris/qt5-qpa- ... 95bf5c9ff0

+ how to run stuff:

Code: Select all

cd /usr/local/Qt-5.2.1/examples/qtwayland/qml-compositor
EGL_PLATFORM=hwcomposer ./qml-compositor -platform hwcomposer -plugin EvdevMouse -plugin EvdevKeyboard &

# weston:
EGL_PLATFORM=wayland weston -Swayland-1 --fullscreen --width=1920 --height=1080 --display=wayland-0

# xbmc - you can start from weston normally, or directly on qml-compositor with:
EGL_PLATFORM=wayland WAYLAND_DISPLAY=wayland-1 /usr/local/lib/xbmc/xbmc.bin —fs -n

#qml code (e.g. minima demo)
EGL_PLATFORM=wayland WAYLAND_DISPLAY=wayland-1 /usr/local/lib/xbmc/xbmc.bin —fs -n

Qt 5.4.1
Wayland 1.7
Weston 1.7

weston now works correctly and reliably.

EDIT: and maynard too

Most of the gnome (3.14) apps work, things will be looking even better with gnome 3.16 apps.
In this new screenshot you can see running: gnome file manager, evince pdf reader, gnome-calculator, gedit, gnome photos, and a video playing.
I also got retroarch working ... and a few cores, although it was pretty unreliable because it was transparent and did not work fullscreen.

amaising, some month ago i wasnt able to compile the qpa-hwcomposer plugin on qt5.4. is this fixed now and with repo are you using for this?

chould you update the steps to compile wayland and co or must i try it on my own?

i will try my luck this weekend

[memeka]

you need to get qt5.4 and revert this patch: https://qt.gitorious.org/qt/qtbase/comm ... d420f58502
then you can build qtwayland, and qpa-hwcomposer.
