            Video Stabilization Standalone Encoder Testing for Versatile
===============================================================================

NOTE:
This test setup is for versatile and does not apply directly to integrator or
Linux workstation testing.

the location of the toolchain and ip addresses are examples here
and can of cource change.

===============================================================================


===============================================================================
                          Setting up the environment
===============================================================================

1. Log into the tool-chain workstation. Current toolchain requires GLIBC_2.3
>ssh hantrodom16

2. Source the tool-chain settings script
> source /afs/hantro.com/i386_linux24/usr/arm/arm-2005q3-2-arm-none-linux-gnueabi-i686-pc-linux-gnu/settings.csh

3. Check out current tag from cvs
> cvs co -r <current_tag> 8290_encoder/software

4. Check "Master" Makefile
> cd 8290_encoder/software/linux_reference
> nedit Makefile
	- set traces if needed
	- set wanted format (INCLUDE_VIDSTAB = y, other n or all y)
    - polling based or not
    - uncomment -DASIC_WAVE_TRACE_TRIGGER if you want support for Logic Analyzer tracing
        
5 Compile kernel modules    

5.1 Compile encoder kernel modlue. Set the path for the kernel sources correctly.
> cd 8290_encoder/software/linux_reference/kernel_module
>make

5.2 Compile linear memory allocater kernel module. Set the path for the kernel sources correctly.
> cd 8290_encoder/software/linux_reference/memalloc
>make

There are scripts for loading these modules! "driver_load.sh" and "memalloc_load.sh"

6. Compile testing program
> cd 8290_encoder/software/linux_reference/test/camstab
> make clean libclean versatile

7. Copy the encoder and scripts to a place where the versatile board can
mount. At the moment this is done by copying to directory /export/work with 
the machine hlabc4 which has AFS access.

> ssh hlabc4
> cp 8290_encoder/software/linux_reference/test/camstab/videostabtest /export/work/your_work_dir
> cp 8290_encoder/software/linux_reference/test/mpeg4/test_vs.sh /export/work/your_work_dir
> cp 8290_encoder/software/linux_reference/kernel_module/hx280enc.ko /export/work/your_work_dir
> cp 8290_encoder/software/linux_reference/kernel_module/driver_load.sh /export/work/your_work_dir
> cp 8290_encoder/software/linux_reference/memalloc/memalloc.ko /export/work/your_work_dir
> cp 8290_encoder/software/linux_reference/kernel_module/memalloc_load.sh /export/work/your_work_dir

You might also have to change test data path in the scripts, depending where
your test data is.


8. log on to the versatile board, as root

> telnet vp1
> cd /export/work/your_work_dir

Load kernel modules!
> ./driver_load.sh
> ./memalloc_load.sh alloc_method=2

===============================================================================
                            Running MPEG4 encoder test scripts
===============================================================================

Standalone VS is using the H264 pipeline stabilization cases, so you need that parameter file.

Run test case number 1750
> ./test_vs.sh 1750

Run all test cases
> ./test_vs.sh all

Compare results for test case 1750 (uses 'cmp' and can be very heavy)
Good idea to run on a workstation.
> ./checkcase_cs.sh 1750

Compare results for all test cases
> ./checkall_vs.sh

if you want CSV file report (dont forget to update TAGs in the script)
> ./checkall_vs.sh -csv

Run testcase 1750 and trigger Logic Analyzer at frame 6
Encoder library had to be compiled with -DASIC_WAVE_TRACE_TRIGGER

> ./test_vs.sh 1750 1750 6

===============================================================================
                            Possible problems
===============================================================================

Possible reasons for errors:
Did make use the corrent system settings ("make versatile")?
Was the memory base set corretly? and the wanted EWL file used?
Correct tool-chain?
Are the paths defined correctly in the scripts?

Kernel modules loaded? check dmesg
