Introduction:

Features:

1. Execute Motion algorithm in both user and kernel space
2. Provide a interface to trigger the motion execution
3. Provide a interface to retrieve testing result, including

• mean, max, min
• comprehensive test log

Supported platfrom

1. i.MX6Q Sabresd with Linux v4.4
2. Cyclone 5 SoC Development Kit with Linux v4.4

Compiling kernel mctest:

Requirement:

• gcc/g++ >= 4.9
• make
• python

Building

ARM

ARCH=arm CROSS_COMPILE=${YOUR_CROSS_COMPILE} \
    KDIR=${YOUR_KDIR_PATH} TARGET=kmod make

X86_64

ARCH=x86  KDIR=${YOUR_KDIR_PATH} TARGET=kmod make

An binary file build/kmod/drivers/mctest.ko would be generated.

Testing kernel mctest:

1. insmod mctest.ko

2. enable mctest kernel trace log, and clean the buffer.

   echo 1 > /sys/kernel/debug/tracing/events/mctest/enable
   echo 0 > /sys/kernel/debug/tracing/trace
   

3. setup number of iteration mctest will execute, and trigger it

   echo 1000 > /sys/devices/virtual/misc/motion-ctrl/experiment/trigger
   

4. retrieve the statistic results

   cat /sys/devices/virtual/misc/motion-ctrl/experiment/result
   

5. retrieve the logs

   cat /sys/kernel/debug/tracing/trace
   

6. End the test:

   rmmod mctest
   

Compiling user mctest:

Requirement:

• gcc/g++ >= 4.9
• make

ARM

```
ARCH=arm CROSS_COMPILE=${YOUR_CROSS_COMPILE} \
TARGET=user make
```

X86_64

```
ARCH=x86 TARGET=user make
```

An binary file build/user/drivers/mctest would be generated.

Testing user kernel mctest:

1. ./mctest &

2. setup number of iteration mctest will execute, and trigger it

   echo 1000 > /tmp/motion/trigger
   

3. retrieve the statistic results

   cat  /tmp/motion/result/statistic_result
   

4. retrieve the logs

   cat  /tmp/motion/result/raw_result
   

5. stop mctest killall mctest

mctest release note:

Warning :

1. only one instance of user mode mctest can be executing simultaneously
