ETH_S_FUNC_PARALLEL_PROCESSING:

source 'common.sh';

prepare_nfs_mount.sh "/mnt/nfs_mount"|| die "Mounting NFS Failed";

multi_run_processes.sh -s "/opt/ltp/runltp -f ddt/eth_ping -P $PLATFORM -s ETH_XS_FUNC_PING # dd if=/dev/urandom of=/mnt/nfs_mount/dd_test bs=1M count=100" -l "-n 2 -a 0x1 -d 1";

unmount_nfs.sh "/mnt/nfs_mount"

prepare_nfs_mount.sh:

source "common.sh"  # Import do_cmd(), die() and other functions
if [ -n "$1" ]
then
  mount_point=$1
  `check_env_var 'NFS_SERVER'`
  `check_env_var 'NFS_ROOT_PATH'`
  mkdir -p $mount_point
  umount $mount_point
  mount -t nfs -o nolock,addr=$NFS_SERVER $NFS_SERVER':'$NFS_ROOT_PATH $mount_point
else
    die "NFS mount point needs to be provided as parameter to script"
fi

check_env_var in common.sh 看看是否存在这个环境变量

check_env_var() {                                               
  output_str=`env|grep $1`                            
  if [ ${#output_str} == 0 ]
  then                                                           
    die "$1 not defined"                                             
  fi                                                              
}

所以需要定义NFS_SERVER和NFS_ROOT_PATH，可以放在env_tools.sh中

export NFS_SERVER=192.168.40.41
export NFS_ROOT_PATH=/home/zhangyi/work/psoc_ltp/ltp_mnt

mount -t nfs -o nolock,addr=$NFS_SERVER $NFS_SERVER':'$NFS_ROOT_PATH $mount_point

挂接有问题，改为

mount -t nfs -o nolock,addr=$NFS_SERVER,nfsvers=3,vers=3 $NFS_SERVER':'$NFS_ROOT_PATH $mount_point

multi_run_processes.sh -s "/opt/ltp/runltp -f ddt/eth_ping -P $PLATFORM -s ETH_XS_FUNC_PING # dd if=/dev/urandom of=/mnt/nfs_mount/dd_test bs=1M count=100" -l "-n 2 -a 0x1 -d 1";

# usage:
# multi_run_processes.sh <process list> [<process list2> ...] -v

#                 for process execution
#
#                 process_list= -s "#-separated commands" -l "-n <num_instances>
#                        -a <cpu affinity mask> -d <inter-process start delay>
#                        -p <priority> -r <realtime priority>"

-s "#-separated commands"  #命令
