Running radeonsi on Ubuntu 13.04

[Cybjit]

There does not seem to be that much information about how to run radeonsi.
So I tried with my HD 7750 on (K)Ubuntu Raring, and documented what I did.

Since glamor is required, and it does not support the X version in Ubuntu, xorg-server has to be downgraded.
While running this process, I had to use a bit of force (dpkg --force-depends -P) to remove conflicting packages.
But in the end, apt is in a OK state.

1. Fetch, build and install debian xorg-server 1.12.4 (git://git.debian.org/git/pkg-xorg/xserver/xorg-server branch debian-unstable).

2. Blacklist xorg 1.13 in apt preferences, to prevent reinstallation.
Package: xserver-common
Pin: version 2:1.13*
Pin-Priority: -1

Package: xserver-xorg-core
Pin: version 2:1.13*
Pin-Priority: -1

Package: xserver-xorg-dev
Pin: version 2:1.13*
Pin-Priority: -1

3. Fetch mesa 9.1 (git://git.debian.org/git/pkg-xorg/lib/mesa branch ubuntu). Add --enable-gbm to debian/rules. Build and install.

4. Fetch glamor (git://anongit.freedesktop.org/git/xorg/driver/glamor). Configure and pay attention to missing dependencies manually, since there is no packaging (./configure --enable-glx-tls --prefix=/usr).
make install.

5. Fetch xf86-video-ati (git://git.debian.org/git/pkg-xorg/driver/xserver-xorg-video-ati branch ubuntu).
In debian/control remove the version dependency for xserver-xorg-dev. Also remove the dependencies on xserver-xorg-video-r128 and xserver-xorg-video-mach64 completely.
Build and install.

6. To get mouse/keyboard, I also had to rebuild xserver-xorg-input-evdev. If you use other drivers, those would also have to be recompiled.
Fetch xf86-input-evdev (git://git.debian.org/git/pkg-xorg/driver/xserver-xorg-input-evdev branch ubuntu). In debian/control remove the version dependency for xserver-xorg-dev.
Build and install.

Those where the minimal changes I was able to get it running with.
LLVM 3.2 in raring already has the r600g driver backported, and kernel 3.8 works.

I also tried latest LLVM git, Mesa git, and kernel 3.9-rc1+, but no significant differences.

KDE Desktop effects works.
Nexuiz runs at 22 fps at 1920x1200.
I thought I have Rochard running, but trying again just gives a black screen.
Torchlight immediately locks up the GPU, but the machine still responds over ssh.
Lightsmark 2008 completely freezes the machine after a few tests.

I could not test Trine, since it crashes the X server both with nouveau and radeonsi.

[Cybjit]

I forgot two steps in xf86-video-ati.

In debian/rules add
override_dh_auto_configure:
dh_auto_configure -- --enable-glamor

In debian/patches/series remove
reverse-prime.patch

[Cybjit]

And another thing I forgot, /etc/X11/xorg.conf needs to be configured:
Section "Module"

Load "dri2"
Load "glamoregl"

EndSection
Section "Device"

Identifier "ati"
Driver "ati"

Option "AccelMethod" "glamor"

EndSection

[Cybjit]

Well, that was a lot of unnecessary work: http://lists.x.org/archives/xorg-dev...ch/035721.html.
It did not even occur to me to try the stock xorg-server, as the Glamor page says it would be unreliable with 1.13+, http://www.freedesktop.org/wiki/Software/Glamor.

I guess step 1, 2 and 6 are unnecessary.

[ChrisXY]

Did you actually have luck in trying it? I tried prime with it and it looks good so far, X.Org X Server 1.14.0, xf86-video-intel with uxa, xf86-video-ati compiled with glamor

But as soon as I do "DRI_PRIME=1 glxinfo" X segfaults

As far as I know this is because prime needs acceleration, i.e. glamor and there is no error reporting for a case where it doesn't work yet.

I even tried "LD_PRELOAD=/usr/lib/xorg/modules/libglamor.so X :1" but I only got "sh: symbol lookup error: /usr/lib/xorg/modules/libglamor.so: undefined symbol: serverClient"

[Cybjit]

Yes, I am using xserver-xorg-core 2:1.13.2-0ubuntu3 now. But I have also upgraded other packages (LLVM git, Mesa git, Linux git), since some crashing bugs are gone with them.

I have not tried using prime.

Since the recent refresh of xorg-edgers repositories, it has become much easier to compile the necessary
mesa support without the need fro llvm3.3. Here is a recipe for easy enabling radeonsi,
tested working on both Ubuntu 12.10 & 13.04. This can be easily made into install script,
feel free to do it at your own convenience.

First, we need to temporarily enable xorg-edgers repo, just to retrieve the sources & some dev tools and libs

sudo apt-get -y install build-essential git xutils-dev xorg-dev
mkdir radeonsi
cd radeonsi
sudo add-apt-repository -y -s ppa:xorg-edgers/ppa
sudo apt-get update
apt-get source mesa
apt-get source xserver-xorg-video-ati
sudo apt-get -y build-dep mesa
sudo apt-get -y install mesa-utils
sudo add-apt-repository -r -y ppa:xorg-edgers/ppa
sudo apt-get update

Next, we compile mesa, with gbm support enabled (this will take some time)

JOBS=$(cat /proc/cpuinfo | grep ^processor | tail -n1 | awk '{ print $3 }')
ARCH=$([ "$(uname -m)" != "x86_64" ] && echo "i386" || echo "amd64")
MESAREVISION=$(ls -d mesa*/ | grep -o "9.[0-9].[0-9]~git[a-z0-9.+]*")
MESAPPAREVISION=$(ls mesa_$MESAREVISION*.dsc | grep -o "\-[0-9]ubuntu[0-9][a-z]*[~_a-z3864]*")
MESAPKGSUFFIX=${MESAREVISION}${MESAPPAREVISION}_${ARCH}.deb
ATIDRVREVISION=$(ls -d xserver-xorg-video-ati*/ | grep -o "[\.0-9]*+git[a-z0-9.]*")
ATIDRVPPAREVISION=$(ls xserver-xorg-video-ati_$ATIDRVREVISION*.dsc | grep -o "\-[0-9]ubuntu[0-9][a-z]*[~_a-z3864]*")
ATIDRVPKGSUFFIX=${ATIDRVREVISION}${ATIDRVPPAREVISION}_${ARCH}.deb
cd mesa-$MESAREVISION
sed -i 's|../../configure --prefix=/usr|../../configure --enable-gbm --prefix=/usr|' debian/rules
time dpkg-buildpackage -b -j$JOBS
cd ..

Next, assuming the mesa compilation was successful, we install mesa packages

sudo dpkg -i libegl1-mesa_$MESAPKGSUFFIX libegl1-mesa-dev_$MESAPKGSUFFIX \
             libegl1-mesa-drivers_$MESAPKGSUFFIX libgbm1_$MESAPKGSUFFIX \
             libgbm-dev_$MESAPKGSUFFIX libgl1-mesa-dev_$MESAPKGSUFFIX \
             libgl1-mesa-dri_$MESAPKGSUFFIX libgl1-mesa-dri-experimental_$MESAPKGSUFFIX \
             libgl1-mesa-glx_$MESAPKGSUFFIX libglapi-mesa_$MESAPKGSUFFIX \
             libgles1-mesa_$MESAPKGSUFFIX libgles1-mesa-dev_$MESAPKGSUFFIX \
             libgles2-mesa_$MESAPKGSUFFIX libgles2-mesa-dev_$MESAPKGSUFFIX \
             mesa-common-dev_$MESAPKGSUFFIX libosmesa6_$MESAPKGSUFFIX \
             libosmesa6-dev_$MESAPKGSUFFIX libxatracker1_$MESAPKGSUFFIX \
             libxatracker-dev_$MESAPKGSUFFIX libopenvg1-mesa_$MESAPKGSUFFIX \
             libopenvg1-mesa-dev_$MESAPKGSUFFIX

Next, time to compile and install glamor. Unfortunately, this will not be packaged into a deb, manuall install is nedeed

git clone git://anongit.freedesktop.org/git/xorg/driver/glamor
cd glamor
./autogen.sh --enable-glx-tls --prefix=/usr
make -j$JOBS
sudo make install
cd ..

Almost there, time to compile and install ati/radeon driver for X

sudo apt-get -y build-dep xserver-xorg-video-ati
cd xserver-xorg-video-ati-$ATIDRVREVISION
sed -i 's|\(XXV=xserver-xorg-video\)|\1\n\noverride_dh_auto_configure:\n\tdh_auto_configure -- --enable-glamor|' debian/rules
sed -i 's|dh_shlibdeps -- --warnings=6|dh_shlibdeps --dpkg-shlibdeps-params=--ignore-missing-info|' debian/rules
time dpkg-buildpackage -b -j$JOBS
cd ..
sudo dpkg -i xserver-xorg-video-ati_$ATIDRVPKGSUFFIX xserver-xorg-video-radeon_$ATIDRVPKGSUFFIX

Finally, all left to be done is a manual change of xorg.conf

[ -f /etc/xorg.conf ] && sudo cp /etc/xorg.conf /etc/xorg.conf.BACKUP.$(date -Iseconds)
TAB="$(printf '\t')"
sudo bash -c "cat > /etc/xorg.conf" << EOF
Section "Module"
${TAB}Load "dri2"
${TAB}Load "glamoregl"
EndSection

Section "Device"
${TAB}Identifier "ati"
${TAB}Driver "ati"
${TAB}Option "AccelMethod" "glamor"
EndSection
EOF

Now, if only somebody with the proper authority can convince xorg-edgers into adding --enable-gbm switch into mesa, this would be way more easier to do...
BTW, anyone heard of glamor deb package?

[Vincenzov]

Hello, I tried to install the radeon 7750, nothing works and the PC consumes 40 watts more.
I just wanted to know why not add support for the series radeonsi Ubuntu 13.04.

[ChrisXY]

Finally, all left to be done is a manual change of xorg.conf

[ -f /etc/xorg.conf ] && sudo cp /etc/xorg.conf /etc/xorg.conf.BACKUP.$(date -Iseconds)
TAB="$(printf '\t')"
sudo bash -c "cat > /etc/xorg.conf" << EOF
Section "Module"
${TAB}Load "dri2"
${TAB}Load "glamoregl"
EndSection

Section "Device"
${TAB}Identifier "ati"
${TAB}Driver "ati"
${TAB}Option "AccelMethod" "glamor"
EndSection
EOF

I don't think this is needed after http://cgit.freedesktop.org/xorg/dri...9ec50ef3b769f1

[Zgembo]

Yes, but that commit is not yet included in a xorg/driver/xf86-video-ati version available at xorg-edgers.
They are at git 3e5350be, from 20130315, and the commit you mention arrived 10 days later...
