Config

This document details how to install the ICE Toolkit software and NeXtMidas for the operation of ICE-PIC6/7/8 series DSP cards on RHEL/CentOS 6/7/8.

Prerequisites

As root,

Install prerequisite packages:

• gcc
• gcc-c++
• glibc-devel
• libstdc++-devel
• kernel-headers
• kernel-devel
• tcsh

ICE Operating User

Create ICE operating user 'iceman':

useradd iceman
passwd iceman
<enter password>

Change iceman's shell to TC-Shell:

usermod -s /bin/tcsh iceman

Directory Structure

Create the following directory structure:

/
|-- ...
|-- mnt
|   |-- data01
|   |-- data11
|   |-- icedisk
|   `-- ramdisk
|-- opt
|   `-- ice
|   |   |-- aux
|   |   |   |-- data01 -> /mnt/data01
|   |   |   |-- data11 -> /mnt/data11
|   |   |   |-- icedisk -> /mnt/icedisk
|   |   |   `-- ramdisk -> /mnt/ramdisk
|   |   |-- pkg
|-- ...

Note that /opt/ice/aux only contains links. This is a matter of convenience so that all of the AUXes can be referenced from within the ICE tree. They can be create as such:

cd /opt/ice/aux
ln -s /mnt/data01 data01
ln -s /mnt/data11 data11
ln -s /mnt/icedisk icedisk
ln -s /mnt/ramdisk ramdisk

The entire /opt/ice directory should be owned by iceman, as well as /mnt/icedisk:

chown -R iceman:iceman /opt/ice /mnt/icedisk

Download Software

Download the latest stable ICE tree and NeXtMidas release from http://www.ice-online.com/software/downloads/stable/

Copy the ICE tree software ZIP archive, the NeXtMidas ZIP archive, and the JDK archive into /opt/ice/pkg and make sure they are owned by iceman:

cp <source path>/iceXXX.zip /opt/ice/pkg
cp <source path>/nxmXXX.zip /opt/ice/pkg
cp <source path>jdkXXX.tar.gz /opt/ice/pkg
chown iceman:iceman /opt/ice/pkg/*

Now switch users to iceman:

su - iceman

Dearchive the software packages and make symbolic links, which makes the paths more manageable and later software upgrades considerably easier:

cd /opt/ice/pkg
unzip iceXXX.zip
ln -s iceXXX icexxx
unzip nxmXXX.zip
ln -s nxmXXX nmxxx
tar -xzf jdkXXX.tar.gz
ln -s jdkXXX jdk

Temporary Files Directory

Create directory for temporary NeXtMidas files:

mkdir ~/tmp

Configuration Files

Modify /opt/ice/pkg/nmxxx/nxm/sys/cfg/nmstartup.mm to include the following (use this as a complete example):

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

startmacro

file name u:aux.11 (opt,ice,aux,data11,+)

path set dsp hwc

env set "HWFILE" "nxm.sys.dat.hwconfig"
res t:km "nxm.sys.cfg.keyMap.tbl"
env set KEYMAP ^km

endmacro

Create the following NeXtMidas macro ~/nmstartup.mm

startmacro

option ice /opt/ice/pkg/icexxx
if "/proc/driver/icepic" fexists then
  pic aux 9
endif
hw file nxm.ice.dat.hwconfig
aux 1 1|2|9|DAT|11|CWD|RAM|HOME

endmacro

Add the following lines to /home/iceman/.cshrc, creating the file if it does not already exist:

#!/bin/csh
#
# Red-Hat System csh.cshrc
if ( -f /etc/csh.cshrc ) source /etc/csh.cshrc
#
# Set environment variables
if ( "${?HOMEDIR}" == 0 ) then
  setenv HOMEDIR /home/iceman
endif
if ( "${?TMPDIR}" == 0 ) then
  setenv TMPDIR $HOMEDIR/tmp
endif
if ( "${?USERPATH}" == 0 ) then
  setenv USERPATH /bin:/sbin:/usr/bin:/usr/sbin:${HOMEDIR}/bin
  setenv PATH ${PATH}:${USERPATH}
endif
if ( "${?ICEPKG}" == 0 ) then
  if ( -e /opt/ice/pkg ) then
    setenv ICEPKG  /opt/ice/pkg
    setenv ICEROOT $ICEPKG/icexxx
    setenv NMROOT  $ICEPKG/nmxxx
    setenv NM_USER_JVM_FLAGS "-Xmx1024m -Xms1024m"
    setenv NMHISTORY_DIR $TMPDIR
    setenv JAVAHOME $ICEPKG/jdk  
    if ( -e $JAVAHOME/bin ) then
      setenv PATH ${PATH}:$JAVAHOME/bin
    endif
    if ( -e $JAVAHOME/jre/bin ) then
      setenv PATH ${PATH}:$JAVAHOME/jre/bin
    endif
    if ( -e /opt/ice/bin ) then
      setenv PATH ${PATH}:/opt/ice/bin
    endif
  endif
endif
#
# Set C-Shell/TCSH environment
if ( "${?LINES}" == 0 ) then
  setenv LINES   
endif
if ( "${?COLUMNS}" == 0 ) then
  setenv COLUMNS   
endif
#
# Aliases
alias ice      ${ICEROOT}/jre/ice
alias nms      source ${NMROOT}/os/unix/nmstart
alias nmstart  source ${NMROOT}/os/unix/nmstart

Now load the setting from the .cshrc file, either logout and log back in as iceman, or

source ~/.cshrc

Compile the Software

Compile NeXtMidas and the ICE tree:

nms
nm make all
nm make all ice
nmend

Build and Install the ICE-PIC Driver

As root, build the driver:

cd /opt/ice/pkg/icexxx/drv/lnx
./icepic make
./icepic install
./icepic start

Note: If you are upgrading the driver from a previous version, first stop and remove the old driver:

./icepic stop
./icepic remove

Configure the kernel line parameters in /etc/default/grub (This example uses kernel allocated memory):

...
GRUB_CMDLINE_LINUX="... ice.ra=2 ice.rd=8000M ice.rm=64M"

Remake grub.cfg:

On Legacy/BIOS systems:

grub2-mkconfig -o /boot/grub2/grub.cfg

On UEFI systems:

grub2-mkconfig -o /boot/efi/EFI/redhat/grub.cfg

Reboot the machine.

Once rebooted, log into a graphical session as iceman.

Check the that the driver loaded and verify that the requested memory buffer size was obtained:

cat /proc/driver/icepic

You should see

RamStart  : XXXX Mby
RamDisk   : 8000 Mby
RamMapped : 64 Mby
...

Try starting NeXtMidas and test the configuration:

nms
nm
nM> plot apenny

Now from within the NeXtMidas shell, detect any ICE-PIC cards that might be installed:

nM> pic detect

Note the PCI-e width and generation.
