Intro: Minimal CentOS 6.5

FIXME - Need to update this since CentOS is no longer installed.

The Spectrum XMC1151 digitizer libraries we have require a specific flavour of Linux to operate.

Download the specific version by getting the http://vault.centos.org/6.5/isos/x86_64/CentOS-6.5-x86_64-minimal.iso which is the “minimal” CentOS 6.5.

Kernel from OS install 2016.04.14 

Linux lvisf 2.6.32-431.el6.x86_64 #1 SMP Fri Nov 22 03:15:09 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

In case your kernel is wrong, you can download the RPM and install directly

  1. Download the correct one (see above) http://vault.centos.org/6.5/centosplus/x86_64/Packages/kernel-2.6.32-431.el6.centos.plus.x86_64.rpm 
    cd ~/download
wget http://vault.centos.org/6.5/centosplus/x86_64/Packages/kernel-2.6.32-431.el6.centos.plus.x86_64.rpm
wget http://vault.centos.org/6.5/centosplus/x86_64/Packages/kernel-devel-2.6.32-431.el6.centos.plus.x86_64.rpm
  2. Install 
    sudo rpm -ivh --oldpackage kernel-2.6.32-431.el6.centos.plus.x86_64.rpm
sudo rpm -ivh --oldpackage kernel-devel-2.6.32-431.el6.centos.plus.x86_64.rpm

Kontron BIOS Changes

  • To make these BIOS changes, we need to get to the UEFI shell.
    1. Reboot the computer
    2. Press <DEL> key while booting to get to BIOS menu
    3. Boot → Boot Option #1 → UEFI: Built-in Shell
    4. Save and Exit (F4)
    5. Press <ESC> while booting to get to the Shell> prompt.
  1. Increase the boot delay so that the Spectrum Digitizers have time to initialise.
    1. Enter the following on the Shell> 
      kboardconfig PciCfgDelay 5s
    2. Double check by running without the argument too see what the parameter is set to
      kboardconfig PciCfgDelay
# will see [5s] highlighted in green (and that is the longest delay available)
  2. Disable hyperthreading and whatever VT stands for NOTE: The non-RT version works great with hyperthreading (at least so far: — David Lloyd Rabine 2018/04/27 18:13 )
    # ONLY RT version needs this DO NOT DO THIS for normal operations with NORT build (build02 / v2)
kboardconfig IntelVT disabled
kboardconfig IntelHT disabled
  3. Exit the bios 
    exit
  • What is SpeedStep? What is CpuTurbo? Sounds like things we don't want on!

Base CentOS

Using the 500_00746_r100_SDR7000_Linux_SG.pdf document, set up the core data system.

CentOS Package Servers

Adding Online Resources

This did work in adding the 6.10 repository to our system: (from) https://www.mark-gilbert.co.uk/fixing-yum-repos-on-centos-6-now-its-eol/ 

curl http://mark-gilbert-co-uk.s3-website-eu-west-1.amazonaws.com/CentOS-Base.repo --output /etc/yum.repos.d/CentOS-Base.repo
curl http://mark-gilbert-co-uk.s3-website-eu-west-1.amazonaws.com/epel.repo --output /etc/yum.repos.d/epel.repo

Use Archived Packages?

Maybe we should grab what we need? I dunno. Maybe we just make an image that we can expand to a 64 GB drive and be happy.

DVD Boot

NOTE: Press the Delete key while booting in order to change the boot to either the USB PLEXTOR drive or the LEXAR CFAST drive

  • BIOS (delete key after eSATA RAID Marvel BIOS) → Boot → Boot Option #1
  • Then F4: Save & Exit
  1. Attached the external USB CDROM drive to the computer via the USB3 port (USB stick with UNETBOOTIN did NOT WORK for me?!) (UnetBootin will work with later version of CentOS image… 6.5 is broken)
  2. Insert the Minimal CentOS 6.5 Install Disk
  3. Boot and set the BIOS to boot off the Plextor drive (our USB based DVD drive)
  4. At CentOS 6 Welcome, Click → Next
  5. Language: English (English)
  6. Keyboard: U.S. English

  8. NOTE: If another OS detected, select: Fresh Installation (SURE YOU WANT TO DELETE THAT OS!?)
  9. Hostname: lvisf
  10. Timezone: New York
  11. root Password: the usual
  12. Partitioning: Create Custom Layout (bottom option)
    1. Delete any partitions on the new target drive (this 32GB cfast is the demo target)
    2. Select the Free disk area → Create a new partition
    3. Select → Standard Partition (top option)
      1. Mount Point: /boot/efi
      2. File System Type: EFI System Partition
      3. Size (MB): 1024
      4. Additional Size Options: Fixed Size (default, but make sure)
      5. OK
    4. Select → Standard Partition (top option)
      1. Mount Point: /
      2. File System Type: ext4
      3. Size (MB): 15360
      4. Additional Size Options: Fixed Size (default, but make sure)
      5. OK
    5. Next
  13. Select the drive (for this case, the 60 GB (or 60000 MB drive) and put that to the right, then Write Changes
  14. Wait for install to complete (205 packages in ~4 minutes)
  15. Drive will eject
  16. Remove DVD
  17. Reboot
  18. Load BIOS on reboot and select the cfast drive as the standard boot device

Hard Drive / Raid

CentOS Configure

Virtual Box

Some notes on using virtual box

Used RedHat 64 Bit as the base machine, worked fine with the CentOS minimal

Local Network

In order to ssh to your host, you can add a rule to port forward into your VM

  1. Network → Advanced → Port Forwarding
  2. Add a rules that maps
    1. Name: Forward SSH (whatever you want)
    2. Protocol: TCP
    3. Host IP: 127.0.1.1
    4. Host Port: 2222
    5. Guest IP: 10.0.2.15 (or whatever your machine is)
    6. Guest Port: 22
  3. Now you can ssh directly from your host pc to the VM (so I can copy and paste from the wiki, yeah!!)
    1. Example: 
      ssh -CY root@127.0.1.1 -p2222

Screen Scale

  1. Display settings for the host, you can scale the screen directly now, up to 200%. YAY!

lvisf Config

Filesystem

  1. Add the navigation, internal and external drives to the /etc/fstab file
    1. Edit 
      sudo nano /etc/fstab
    2. Add these lines 
      LABEL=LVISF_INTERNAL	/mnt/internal		ext4	defaults,noatime 	0 0
LABEL=LVISF_EXTERNAL	/mnt/external		ext4	defaults,noatime 	0 0
LABEL=LVISF_NAV		/mnt/nav		ext4	defaults,noatime 	0 0
tmpfs                   /mnt/ramdisk            tmpfs   nodev,nosuid,noexec,nodiratime,size=1M   0 0
    3. Make these directories for mount points 
      sudo mkdir /mnt/internal /mnt/external /mnt/nav /mnt/tmp /mnt/usb /mnt/nfs /mnt/ramdisk
    4. Note: Ram disk information: https://www.jamescoyle.net/how-to/943-create-a-ram-disk-in-linux

Network Temporary Configuration (DHCP)

  1. Setup the system for DHCP for now
    1. Log in as root
    2. Use vi to edit /etc/sysconfig/network-scripts/ifcfg-eth0 so 
      ONBOOT=yes
    3. Startup network (will take a moment, DHCP) 
      sudo ifup eth0
  2. Logout and now, you should ssh to gs694-lvisdev.gsfc.nasa.gov and then to the new machine (whatever its DHCP IP address is now on the local LAN)

Prerequisites for Compiling Kernel Modules

Remove Unused Services

  1. Remove exim (NOTE, this was not on the CentOS Minimal I just installed 2018.01.04 (but leaving for historical))
    1. Stop the service 
      sudo service exim stop
    2. Remove the package from the system

      sudo rpm -e --nodeps postfix

eSATA Speed Limit

Our eSATA connection to the raid (and any external ATA devices) was occasionaly running into issues when running at high speed (6.0 GBPS). Dan Caplan found online notes that people put a speed limit on the kernel module that regulates the ATA commuincations, and that solved the types of errors we have been seeing.

  1. Modify /etc/grub.conf by adding this to the kernel starting command line 
    libata.force=3.0

/etc/grub.conf

#boot=/dev/sda1
device (hd0) HD(1,800,200000,a70d9e49-77c1-4fc8-b5ce-81ede8517477)
default=0
timeout=5
splashimage=(hd0,1)/boot/grub/splash.xpm.gz
serial --unit=0 --speed=115200 --word=8 --parity=no --stop=1
terminal --timeout=5 serial console
hiddenmenu

        root (hd0,1)
        kernel /boot/vmlinuz-2.6.32-431.el6.x86_64 ro root=UUID=2804bc4c-c850-4d83-9fec-7de10cb1e2b4 rd_NO_LUKS rd_NO_LVM LANG=en_US.UTF-8 rd_NO_MD SYSFONT=latarc

        initrd /boot/initramfs-2.6.32-431.el6.x86_64.img

Kernel Console Redirection

If you want to send the kernel messages out to the serial port for logging.

  1. Modify /etc/grub.conf so the default kernel command line redirects console to the serial port 
    sudo nano /etc/grub.conf
    1. Change
      rhgb quiet
    2. To 
      rhgb console=tty0 console=ttyS0,115200n8

Enable Serial Console Login

And, to make it such that you can log onto the system over that console port…

  1. Modify the grub boot line and add the following lines above all the kernel options
    1. Edit /etc/grub.conf 
      sudo nano /etc/grub.conf
    2. Make the top look like this 
      serial --unit=0 --speed=115200 --word=8 --parity=no --stop=1
terminal --timeout=5 serial console
hiddenmenu
    3. Add these lines to the kernel that you are using (probably already done, see above!)
      console=tty0 console=ttyS0,115200n8
  2. Add ttyS0 to the /etc/securetty file
    1. Edit 
      sudo nano /etc/securetty
    2. Append this to the bottom of the file 
      ttyS0
  3. Modify /etc/init/ttyS0.conf 
    sudo nano /etc/init/ttyS0.conf
  4. And fill it with the following code 
    # ttyS0 - getty
#
# This service maintains a getty on ttyS0 from the point the system is
# started until it is shut down again.

start on stopped rc RUNLEVEL=[2345] and (
            not-container or
            container CONTAINER=lxc or
            container CONTAINER=lxc-libvirt)

stop on runlevel [!2345]

respawn
exec /sbin/getty -L 115200 ttyS0 vt102
########

Spectrum Config

Still as root logged into the main desktop

  1. Disable the Firewall
    1. Turn off the firewall 
      sudo service iptables stop
sudo service ip6tables stop
    2. Make this permanent 
      sudo chkconfig iptables off
sudo chkconfig ip6tables off
  2. Disable SELinux
    1. Edit the configuration file 
      sudo vi /etc/selinux/config
    2. Modify the file
      1. From 
        SELINUX=enforcing
      2. To 
        SELINUX=disabled
  3. Reboot for all changes to take place

Minimize Kernel Modules

  1. Disable ipv6, this addition is required along with a line in the modprobe file below
    1. Modifiy /etc/sysconfig/network 
      sudo vi /etc/sysconfig/network
    2. And append the following two lines 
      NETWORKING_IPV6=no
IPV6INIT=no
    3. Add these two lines to sshd_config 
      sudo nano /etc/ssh/sshd_config
# lvisf - ipv4 only
AddressFamily inet
ListenAddress 0.0.0.0
  2. Blacklist kernel modules we don't require
    1. Edit a file lvisf-blacklist.conf 
      sudo vi /etc/modprobe.d/lvisf-blacklist.conf
    2. Add the following lines 
      # lvisf kernel module blacklist
# version 1.0 - dlr - 20160418

# ipv6
blacklist ipv6

# NMI watchdog
blacklist iTCO_wdt 
blacklist iTCO_vendor_support

blacklist i2c_i801
# blacklist igb
blacklist lpc_ich
blacklist shpchp
blacklist dm_mirror

# intel sound
blacklist soundcore
blacklist snd
blacklist snd_seq
blacklist snd_hda_intel
blacklist snd_hda_codec_hdmi

# USB controller (still loads)
blacklist xhci_hcd


# this is required to REMOVE ipv6 module, I am not sure why
# http://www.cyberciti.biz/faq/redhat-centos-disable-ipv6-networking/
install ipv6 /bin/true

Extras

  • These two commands will remove some other modules I couldn't figure out how to make permanently go away 
    # USB driver... if you're using the nousb kernel, this will work
sudo modprobe --remove xhci_hcd
sudo modprobe --remove dm_mirror

Innovative Digitizer Drivers

Described in LinuxNotes.pdf (might be this /usr/Innovative/MalibuRed-1.3/KerPlug/LinuxNotes.pdf)

  1. Link our Innovative directory to /usr/Innovative
    sudo ln -s /opt/lvisf/src/Innovative /usr/Innovative
  2. Untar the latest driver 
    tar -zxvf /opt/lvisf/src/tars/64WinDriver-12.3-0.X86_64.tgz.tar.gz --directory=/usr/Innovative/
  3. Build 12.3 Windriver
    1. Link 12.3 as our Windriver 
      cd /usr/Innovative
rm /usr/Innovative/WinDriver
ln -s WinDriver-12.3 WinDriver
  4. Go here
    cd /usr/Innovative/WinDriver/redist
    1. Configure 
      ./configure
make
sudo make install # they say do not do this, we live on the edge
  5. Kerplug
    1. Build (builds in the LINUX directory for the RT kernel) 
      cd /usr/Innovative/KerPlug/linux
./configure
make
    2. OK, this SHOULD fail.
    3. Edit the Makefile with 
      nano Makefile
      1. Add seven dot dot slashes to the line:
        1. Convert this 
          MOD_CSRCS = $(WD_BASEDIR)/redist/linux_wrappers.c
        2. to this 
          MOD_CSRCS = ../../../../../../../$(WD_BASEDIR)/redist/linux_wrappers.c
      2. Change 1180 to 1230
    4. Run make again 
      make
    5. Load the driver 
      sudo insmod LINUX.2.6.32-431.el6.x86_64.x86_64/kp_malibu_module.ko
    6. Need to link the generic library name with the compiled library 
      cd /usr/Innovative/KerPlug
sudo ./quicklink wdapi 1230
  6. Final license issue with changed authorization mode
    1. Install qt development 
      sudo yum install qt4 -y
sudo yum install qt4-devel -y
    2. Rebuild (and this will also copy the files where they need to go) (NOTE: I believe this is unnecessary, but it does not hurt anything to do this)
      cd /home/lvis/src/Innovative/Malibu/Qt/Os_Mb
qmake-qt4
make

Historical Log

All of this below is just for historical records. Do NOT need to do any more Innovative.

Raw code from /etc/rc.local from the primary machine to load this 

sudo bash
cd /usr/Innovative/WinDriver-12.3/redist && ./wdreg LINUX.2.6.32-431.el6.x86_64.x86_64/windrvr1230 auto
#/usr/Innovative/winCloudDrvr/winclouddrvr_installation/redist/wdreg winCloudDrvr auto
#chmod 666 /dev/winCloudDrvr
insmod /usr/Innovative/KerPlug/linux/LINUX.2.6.32-431.el6.x86_64.x86_64/kp_malibu_module.ko
exit
Field Addendum

In the field we noticed that the driver was saying unregistered, and would only run for 60 minutes (sometimes it ran longer, but this was an issue). Dave found these instructions from an email: 

FIRST!

Make sure this folder exists:

/usr/Innovative/Lib/Dll (and it is linked to the Innovative folder in src)

Make sure LicenseLoader.so exists in that folder.

(I have attached that file and a tar of the 3 others needed to rebuild)

Hopefully its just that the .so did not make it to that system disk. 

If is does exist:

Copy all the files in the tar to:

/home/lvis/src/Innovative/Malibu

Cd to /home/lvis/src/Innovative/Malibu/Qt/Os_Mb

“qmake-qt4”
“make”
 
This will make the Os library and copy it to the correct folder.
 
“That is all I got” 😊

Auto-load Plx9030 Driver

NOTE: (in lieu of step 2 below) I had this not work when I manually edited it the first time. A copy of the file is in the repository, you could just copy that file in: 

sudo cp /opt/lvisf/src/lvisF/scripts/lvisf.modules /etc/sysconfig/modules/lvisf.modules
  1. symlink the driver into the kernel so it will come up on boot 
    sudo ln -s /opt/lvisf/src/PLX/PlxSdk/Driver/Source.Plx9000/Output/Plx9030.ko /lib/modules/2.6.32-431.el6.x86_64/kernel/drivers/misc/
  2. add to our startup script /etc/sysconfig/modules/lvisf.modules
    1. modify the file 
      sudo nano /etc/sysconfig/modules/lvisf.modules
    2. add the following 
      # start the Plx9030 syncclock32 driver
/sbin/modprobe Plx9030
  3. symbolically link in our rc.local into /etc/rc.local
    1. remove the original 
      # remove the symlink
sudo rm /etc/rc.local
# move the original to something else
sudo mv /etc/rc.d/rc.local /etc/rc.d/rc.local_orig
    2. link in the lvisf version 
      sudo ln -s /opt/lvisf/src/lvisF/scripts/rc.local /etc/rc.d/rc.local
sudo ln -s /etc/rc.d/rc.local /etc/rc.local
    3. verify that the system will not try to launch on boot (unless that is what you want!) 
      # look for this near the top
AUTOSTART_LVISF="false"

Clean Boot Operations

Load Drivers

  1. Load the MIC-3753 DIO Drivers 
    sudo insmod /home/lvis/src/MIC3753/linux_driver_source_3.2.7.0_64bit/drivers/bin/biokernbase.ko
sudo insmod /home/lvis/src/MIC3753/linux_driver_source_3.2.7.0_64bit/drivers/bin/bio1753.ko
  2. Load the SyncClock32 Timer Drivers 
    cd /home/lvis/src/PLX/PlxSdk/Bin
sudo ./Plx_load 9030

Compile Code

  1. Enter the build directory for lvisf 
    cd /home/lvis/src/lvisF/build
  2. Use cmake 
    cmake ../
  3. Build code 
    make

Run Tests

User Space Latency Test

  1. Enter the testing program 
    cd /home/lvis/src/lvisF/build/bin/tests/syncclock
  2. Run the latency program 
    sudo ./galvMove

Latency Tweaking

  • Set CPU affinity to CPU 3 with something like, made it much more consistent since I guess most things go for CPU 0 by default 
    CPU_SET(3, &cpus);
  • Change the scheduler policy, this information is displayed in the syncclock test program 
    sudo chrt --fifo 99 ./galvMove
  • Isolate a CPU, and then have the code attach itself to that cpu
    • In /etc/grub.conf add this command to the kernel command line, so all user space code will avoid CPU 2 and 3 in this example, leaving 0 and 1 for the OS
      isolcpus=2,3
    • Change the program such that 
      CPU_SET(3, &cpus);
    • Run the program with chrt or not 
      sudo chrt --fifo 99 ./galvMove
  • Set the timer card interrupt affinity to a single CPU (not the prime) 
    sudo bash -c 'echo 2 > /proc/irq/19/smp_affinity'
    • Using 2 here put the interrupt 19 servicing on CPU 1 exclusively
  • More low latency items to add to the kernel command line for /etc/grub.conf 
    rhgb nousb quiet isolcpus=2,3 nosoftlockup mce=ignore_ce audit=0
    • nosoftlockup disables backtrace functionality
    • mce=ignore_ce ignores corrected errors
    • audit=0 disables kernel components of the audit subsystem

Testing

  • Testing delays
    • Install perf 
      sudo yum install perf
    • Run this command to record some latency data
      cd /opt/lvisf/src/lvisF/build/bin/tests/syncclock
sudo perf sched record -o /dev/shm/perf.data chrt --fifo 99 ./galvMove
    • Run the following to read the data 
      sudo perf sched -i /dev/shm/perf.data latency > /tmp/perf.latency.report

Show Interrupt Status

  • This command shows interrupts for each core / CPU 
    cat /proc/interrupts
# notice that CPU1 has all the timer card interrupts (PLx9030)
[lvis@lvisf syncclock]$ cat /proc/interrupts
           CPU0       CPU1       CPU2       CPU3

Test Results

  • 2016.04.27: Ran a test for 2.7 hours. We missed 46 shots out of 49097902 at 5khz (200 useconds) so as far as actually reacting to the interrupt, we are in good shape.
  • Time to make a build 1 data system and get better numbers as we do all our tasks.
