46  Linux Stuff / General Linux questions / Re: D2Plug - voice is chopping/slowdown when backlight power down on: December 07, 2011, 04:19:09 AM
but I think is not marvell issue

it is unbuntu power mangement behavior

you could look below post, it since someone used ubuntu system also facing same issue

So... this is mean it work or it not work?

I think system into idle state is base on user setting at ubuntu system , do you used I post method to trun off power mangment and screen saving than give a try
49  Linux Stuff / General Linux questions / Re: D2Plug - voice is chopping/slowdown when backlight power down on: November 24, 2011, 08:21:21 PM
I nou used MPD before

could you let me know your used case through network, local ... due to mpd is a dameon so if you play at local whcih player play it

BTW prevent it I think you could tuen off SCreen Saver at System->SCreen Saver and some monitor setting at power mangiment at System->power mangerment

another thing you need to check is when you play vedio (for exapmle type totem <vedio name> at consloe or x-terminal), you could see some word like "vmeta" at console , you have this word mean you have get hardware accerlate

if used totem still bad, could you share your test vedio clip for me

51  Linux Stuff / General Linux questions / Re: oprofile on D2plug on: November 23, 2011, 09:45:56 PM
I list what we do here, maybe it could help you

first all , I try more time at oprofile 0.95 version, not 0.97 , 0.97 is my base 0.95 modify than porting to 0.97, so if possible ,try 0.95 version first

I perform below command at console, sometimes I have see opreport show up can't find sample file, than I re-test 1-2 times , it will back to normal

sudo opcontrol --init  //if you second test you could used reset
sudo opcontrol --setup --no-vmlinux --event=CYCLE_COUNT:20000000
sudo opcontrol --start --session-dir=/home/ubuntu/<my save log folder>

export DISPLAY=:0.0 //if you used xtermal (I not give a try) , you don't type this
totem <vedio clip name> & //totem running at backgroud, await a while (almost 1 -2 min) ,this is my case, maybe not need to wait so long

sudo opcontrol --stop

opreport --session-dir=/home/ubuntu/<my save log folder>

BTW, do you used totem to play vedio ,toem has pre-install at rootfs , others player maybe not get VPU/GPU accelerate
53  Linux Stuff / General Linux questions / Re: oprofile on D2plug on: November 22, 2011, 08:07:44 PM
I think you start / stop too short

for my case, after start ,  perform cp cammand to copy vedio file, used toem to play vedio

after these than type stop, and used opreport , I could see some data

BTW , if your log save loaction , you don't have permession , also have problem , if this way ,try to used "--session-dir" parameter to chang record and report path

I hve try 1080P resolution

but I think something need to be clarify

1.as I remember ,I have discuss about this at another thread , I think need to make sure , you used latest rootfs,kernel form this (http://www.plugcomputer.org/downloads/d2plug/index.html)download page

2.there are too many vedio format at world , I didn't try too many format , so maybe you  used fomat , I not give a try

3. if you put vedio source at SD card , as I know SD card has class 6 and class 10 , used class 10 will be better

4. your blocky mean is ... , I mean this is sometimes, very often or hard to see it ?
55  Linux Stuff / Linux distributions / Re: lib modules build missing on: November 22, 2011, 03:40:56 AM
not need to rebuild kernel

you need to rebuild your usb wifi module source

due to this source need some header form kernel , so when you rebuild your usb wifi modules need to point out which kernel source loacte

this is why I suggest you build it at host PC ,

due to need to modify your usb wifi modules Make file and this is for business used, I think you could ask your wifi module vendor help
56  Linux Stuff / Linux distributions / Re: lib modules build missing on: November 21, 2011, 08:52:56 PM
Sorry, I don't have your usb wifi card on hand , so I can't give a try

but could I know why you can't used build-in wifi modules

BTW base on your error message , under the "/lib/modules/<kernel version>/build" is kernel source

so I think you are not install fail ,it should be build module fail when it try to find kernel,

I think you could do this by below two way

1.copy kernel source to below message mention folder and re-build it
2.build it at host(x86) device , used cross_compiler( you could find it at http://www.plugcomputer.org/downloads/d2plug/index.html) and
   modify your usb module make file , to let it to find your d2plug kernel source at host PC, than re-build it

I use D2Plug play vedio , it look like smoothly , I play H264 format vedio, I not see any problem here
58  Linux Stuff / General Linux questions / Re: oprofile on D2plug on: November 21, 2011, 03:19:10 AM
I think you not add Marvell PJ4 event at opfrofile source

I have done it for you , attach zip file contain two version oprofile patch , one is for 0.9.5 another is for 0.9.7 , I think you uncompress it see the file name will know it

I also list how to make it for your reference

follow the procedure to build that
   $> sudo apt-get install gcc-4.1 cpp-4.1 g++-4.1
   $> sudo apt-get install libpopt-dev binutils-dev
   $> cd <oprofile folder>
   $> CC=gcc-4.1 CPP=cpp-4.1 CXX=g++-4.1 ./configure --with-kernel-support
   $> make
   $> sudo make install
   $> sudo opcontrol --init
   $> ophelp
59  Hardware and U-Boot firmware / Hardware / Re: D2Plug - Log files flooded with error mesages related to /dev/sda on: November 20, 2011, 08:13:15 PM
But I still suggest ,you could connect with USB-flash ,SD card , or hard-disk through eSATA to test it

this way could know even there are flooding message as you see ,the real function work normal or not
60  Hardware and U-Boot firmware / Hardware / Re: D2Plug - Log files flooded with error mesages related to /dev/sda on: November 17, 2011, 08:53:06 PM
I assume you connect to usb flash-disk or harddisk through e-Sata

Do you mean these device not working or has some problem

if not , I think it just a information from kernel

not relate to your file-system
