Upd 20-12-2013 : OpenSuSE RPI 13.1 20131206I + 3.11.x+hack

[remsnet]

Hello Folks,

This kernel hack FIXed the SHDC / SHDX kernel issues on OpenSuSE 12.3 with class 6/10 cards Bigger then 16GB.
Myself have 64GB SD Cards from Kingson / Sandisk in use.

Bernhard made the raspberrypi-opensuse-20131206Image avalible :
http://www.zq1.de/bernhard/linux/opensu ... 06x.img.xz

I Found an workaround : Installed the Debianbetta kernel on Open Suse 13.1 Raspberrry .
OpenSuSE RPI and debian RPI seems to use the SAME Kernel source repro at Current.

I got 3.8.13 ( rpi-update "next" BRANCH current ) /
3.9.3 ( selfcompiled ) running on the 20130407 Image

How HACK that kernel Update on you RPI:
( assume you have 3.6.11 as current i.e , but works for older as well - NO warranty - TEST KERNEL - ):

#----Simple Users Guide -----RPI-TEST-Desktop-Kernel---------

1- backup :

Code: Select all

 tar cpfj  /root/bootsuseold3611.tar.bz2 /boot

bevor we start , do:

Code: Select all

 
zypper update
zypper upgrade
reboot

2- Instal git, sudo, wget, 7z

Code: Select all

   zypper  install git-core sudo wget p7zip

3- Install the rpi-update script ( from GIt-HUB , RPI Linux, popcornmix and others )

Code: Select all

 wget http://goo.gl/1BOfJ -O /usr/bin/rpi-update && sudo chmod +x /usr/bin/rpi-update

4- kernel Update to 3.11.x Latest ~ ( DEC 2013 ) ALPHA TEST KERNEL & Firmware

Code: Select all

BRANCH=next rpi-update

see at https://github.com/Hexxeh/rpi-firmware/ for latest Prebuild RPI Firmware.

Note - rpi-update
if rpi-update does not update - saing you have it allready -
then delete the repro copy at /root/.rpi-firmware just and run rpi-update again

Code: Select all

 rm -rf  /root/.rpi-firmware
 

5. reboot

6- "next" Kernel 3.11.x+ or newer - Have fun using your new kernel.

lb2:~ # uname -a
Linux app1 3.10.19+ #600 PREEMPT Sat Nov 16 20:34:43 GMT 2013 armv6l GNU/Linux

Note 08-May-2013 - BRANCH=next featgers
This test RPI Update 3.8.x have ´nd LCX , KRB5 , DLM , USBLP , SPI options at Current,
ipvs and aprd where added at 3.8.10 due my requests, thus nfsroot shuold work with rarp now.

Note IPVS & ipvsadm
ipvs been successfuly with an patched ipvsadm ( rasberian debian 1.26.-2 are incomplete patched )
an patched & precompiled RPI ipvsadm Tarball are droped to https://www.dropbox.com/sh/2pkbntk4enwt ... RPI-binary
reported gotten issues with ipvsadm to lvs-users mailing list.

Myself provide this Guide for selfhelp..
Someone ask me do delete this help .. sorry fellows - I don´t do that .

So many SD card Corruption and / or stabilty issues
with +16G issues with class 6/10 seen here past Weeks ,
and most Users ask for FIX or either an workarround.
Reinstall the OS all 3 weeks / manualy fsck on sutch cards may the wrong way.

AnyHow : DON´T Juge the PI for Software issues with RPI Firmware & Kernels.

7. Compile & Install your own Kernel +3.8.7 and up

- see http://elinux.org/RPi_Kernel_Compilation

- get and Install required Software to compile kernel:

Code: Select all

  zypper install   gcc  make  autoconf  automake  bison  flex  gettext  u-boot-tools ncurses-devel
 

- download attached config-3.8.7.ipvs+krb5+arpd.tar.bzip2 to /usr/src:

Code: Select all

cd /usr/src
wget http://www.raspberrypi.org/phpBB3/download/file.php?mode=view&id=3174&sid=960bc650c8639db17984e8c8de720450

.. use GIT or ZIP or whatever you like ...

- get RPI 3.8.y source as GIT clone from GitHUB and push the config

Code: Select all

cd /usr/src

cat  >git3.8.y-update.sh << EOF

#!/bin/sh
#  
# Simple GIT fetch latest RPI "next" Kernel source tar ball script ..

cd /usr/src
if [ ! -d SOURCES ]; then
  mkdir SOURCES
fi
if [ ! -d GIT ]; then
        mkdir GIT
fi
cd GIT
        if [ -d .git ]; then
                rm -rf .git
                rm .gitignore .mailmap
        fi
git init

D=`date +"%m-%d-%Y"`

if [ -d rpi-3.8.y.$D ]; then
        rm -rf rpi-3.8.y.$D
fi
mkdir  rpi-3.8.y.$D
git fetch git://github.com/raspberrypi/linux.git rpi-3.8.y:refs/remotes/origin/rpi-3.8.y
git checkout rpi-3.8.y
cd /usr/src/GIT
mv ./* rpi-3.8.y.$D

tar cpfj /usr/src/SOURCES/rpi-3.8.y.$D.tar.bz2    rpi-3.8.y.$D
#
# EOF

chmod 755 git3.8.y-update.sh
./git3.8.y-update.sh

cd /usr/src
tar xpfj  SOURCES/rpi-3.8.y.$D.tar
rm linux
ln -s linux-rpi-3.8.y.$D linux


tar xpfj config-3.8.7.ipvs+krb5+arpd.tar.bzip2
cp linux/.config .config_386

- get RPI 3.8.y source as ZIP from GitHUB and push the config

Code: Select all

cd /usr/src; D=`date +"%m-%d-%Y"`
wget https://github.com/raspberrypi/linux/archive/rpi-3.8.y.zip
mv rpi-3.8.y.zip rpi.3.8.y.D.zip
7z x rpi-3.8.y.$D.zip 2>/dev/null
rm linux
ln -s linux-rpi-3.8.y linux

tar xpfj config-3.8.7.ipvs+krb5+arpd.tar.bzip2
cp linux/.config .config_386

#---EDIT3-22042013- updated patch instructions for 3.8.x --------------------------------
- Updated attached .config to my selfcompiled v3.8.7 kernel.
- KRB5 options enabled ( secure NFS with KRB requirement )
- ARPD / RAP options enabled ( Linux Virtual Server & NFS boot
- IP_VS options enabled. ( Linux Virtual Server requirement )
- CONFIG_FUSE_FS=m enabled ( fuse ZFS requirement )
- CONFIG_CIFS_SMB2=y enabled ( samba 4 requirement )
- CONFIG_SQUASHFS=m enabled
-CONFIG_SECURITY_SELINUX enabled.
- CONFIG_CRYPTO* CONFIG_XZ* and subfeatgers enabled

Notes & Issues :
- CONFIG_MMC_BCM2708=[m|y] failed to build - disabled , code bug
see https://github.com/raspberrypi/linux/issues/277

- CONFIG_BCM_VC_CMA=y , can´t build as Module anyhow.
see https://github.com/raspberrypi/linux/issues/277

-mfloat-abi=hard compiled kernel seems not work with any < 3.9.x <
see https://github.com/raspberrypi/linux/issues/276


- using-Class 6 and 10 SD cards seems Forbidd to use OverClocking allways
when use SDcards and often also USB-sticks devices.
It been reported as well when use external Terabyte USB 2.0 Disks as ROOT disks .
This will cause to Coorupt ANY Filesystem type on the used devices - verified.
Root cause seems : The used RPI SD card controler are overvolated and overfrequenced and go OUT of SPEC.
see i.e https://github.com/raspberrypi/linux/issues/280


- Adding LXC will one of my next targets -
seems require extra patches( i.e CONFIG_MMC_BCM2708 ) ,
if any Coder can help , send me an personal Note.

- rpi-3.8.y "next" seems updated to 3.8.12 so no extra Incremental Patching at current.
just wait for next

#-------------------------------------------------------------------------
Make the kernel

Code: Select all

cd /usr/src/linux
make oldconfig
 nohup make \
 CPPFLAGS="-Ofast -mfpu=vfp -march=armv6zk -mtune=arm1176jzf-s" \
 CFLAGS="-Ofast -mfpu=vfp -march=armv6zk -mtune=arm1176jzf-s" \
 dep zImage modules &

go sleep ######### … hours later ... i.e Next day if you compile on the PI Model B
install kernel same way as described here :
http://elinux.org/Talk:RPi_Kernel_Compi ... le_example

Code: Select all

cd /usr/src/linux
kversion=$(make -s kernelrelease)
echo $kversion

cp System.map /boot/System.map-$kversion
cp System.map /boot/System.map

make ARCH=arm modules_install INSTALL_MOD_PATH=/

make ARCH=arm INSTALL_PATH=/boot/ install  

cp .config /boot/config-$kversion
cp ./Module.symvers  /boot/symvers-$kversion
cp arch/arm/boot/Image /boot/kernel.img

if you want an compressed kernel : make ARCH=arm INSTALL_PATH=/boot/ zinstall

Check it :

ls -l /lib/modules/3.8.6-4-raspberrypi/
ls -l /boot/

Update please /boot/cmdline.txt and /boot/config.txt and /etc/sysctl.conf , uppon your own needs

lb2:/boot # cp cmdline.txt cmdline.txt.orig
lb2:/boot # cp config.txt config.txt.orig

vi /boot/cmdline.txt

Code: Select all

console=ttyAMA0,115200 kgdboc=ttyAMA0,115200  elevator=noop sdhci-bcm2708.missing_status=0 sdhci-bcm2708.sync_after_dma=0 profile=2 loglevel=7  console=tty1 root=/dev/mmcblk0p2 rootfstype=ext4 rootflags=commit=120,data=writeback rootwait ro

http://blogofterje.wordpress.com/2012/0 ... n-sd-card/
To further reduce IO and increase performance,
the following seem to be common recommendations, that he did:

Change /etc/fstab so that entry for root partition fourth parameter
is changed from “default” to “default,noatime,nodiratime”
Add linux boot parameter “elevator=noop” in u-boot so that the kernel does not
assume that the disk is a spinning medium and does not try to incorrectly optimize the IO.

The Important flags for SD(HC/HX) cards +16G ( i.e class 6 / 10 ) are the
elevator=noop
sdhci-bcm2708.missing_status=0
sdhci-bcm2708.sync_after_dma=0


This are the AFAIK default settings for some more :

dwc_otg.microframe_schedule=1
dwc_otg.fiq_fix_enable=1
sdhci-bcm2708.enable_llm=1
dwc_otg.lpm_enable=0


If it doesn't help, you can install the "watchdog"-package. Add the "bcm2708_wdog" module to /etc/modules (and invoke "modprobe bcm2708_wdog"), install the watchdog package and uncomment the line with "watchdog-device =" in it.


vi /etc/fstab

Code: Select all

...
/dev/mmcblk0p2  /               ext4    default,noatime,nodiratime  0       1
...
