And really, use dsp profile with limits 250-805, do not lock frequencies, kernel will do the correct job for you.

until new camera-ui is ready you may use the following workaround for higher fps:

tracker-processes -t
renice 10 `pidof camera-ui`
renice 10 `pidof Xorg`

Didnt wanna sound impatient, 805/600 is the clock I normally use for recording, tried 900 a/p your advice on a previous post.

Thanks once more for your enthusiasm towards the project ... CSSU ..and n900

cheers

Darn, I broke it. Here is a list of my tinkering today:

updated kernel-power with today's build
apt-get install --reinstall libbridge2
copied libgstdsp.so from first post
rebooted

And now the boot video freezes, camera cannot record video and I can't play any video with the exception of test1.mkv (Big Buck Bunny) which miraculously plays fine. Other files give me the 'unsupported media file' error after a few seconds of five dots.

I found this in dmesg

Code:

[   10.553222] dspbridge_init: 600000 bytes @ 80e00000
[   86.486602] bridge_deh_notify: ********** DEVICE EXCEPTION **********
[   86.486633] bridge_deh_notify: DSP_SYSERROR, err_info = 0x300
[   86.486785] print_dsp_trace_buffer:

[   86.491455] procwrap_detach: deprecated dspbridge ioctl

[   86.958953] wait_for_start: Timed out waiting DSP to Start
[   86.959869] DSP Bridge driver loaded

and each time I try to play a video with media player this shows up in dmesg:

Code:

[17210.087890] HWRecoveryResetSGX: SGX Hardware Recovery triggered

Attempting to use gst-launch0.10 results in this:

Code:

Pipeline is PREROLLING ...
create_node: dsp node create failed
init_node: dsp node creation failed
ERROR: from element /GstPlayBin2:playbin20/GstURIDecodeBin:uridecodebin0/GstDecodeBin2:decodebin20/GstDspVDec:dspvdec0: couldn't start node
ERROR: pipeline doesn't want to preroll.

But no SGX recovery occurs.

Now, where did I mess up and how can I fix it? (Bold questions I know)

hi freemangordon...
firstly thank u for ur brilliant work & for ur dedication to the community...

NOW MY ISSUE..

After installing kp49 latest version...on loading dsp profile..
boot video crashes and the videos are not played which were earlier played with ur previous methods..
but strange when i change vdd1=0 and reboot (ON DSP PROFILE)
everything works flawlessly
earlier i was using overclocked profile of karam 500-805 vdd1=0 vdd2=0 and everything was ok..
are there any issues if i keep using my phone with dsp profile vdd1=0 and vdd2=1 (I mean overclocking damage risks)..?
thanks...

EDIT : Reboots are occuring with vdd1=1 ..

First off all, thanks to the developers for the efforts you put in this project

But after I did the whole process for being able to play 720p videos on my n900, all I get if I want to play a video is:

Code:

~ $ gst-launch playbin2 uri=file:///home/user/MyDocs/TWOGK_01.mp4
Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
dsp_init: dsp open failed
create_node: failed to register ringio node library
init_node: dsp node creation failed
ERROR: from element /GstPlayBin2:playbin20/GstURIDecodeBin:uridecodebin0/GstDecodeBin2:decodebin20/GstDspVDec:dspvdec0: couldn't start node
ERROR: pipeline doesn't want to preroll.
Setting pipeline to NULL ...
Freeing pipeline ...
~ $

I am using the new KP49 and set it to dsp but nothing changed.
Also tried as sudo but same error.
any advice?

Seems correct DSP binaries are not in /lib/dsp

thx for the reply^^
fixed it myself after something went wrong with the kernel settings it didn't start and I accently instead of reflashing only the kernel I reflashed my whole root filesystem and lost all my apps xD
I installed everything and noticed that the video is heavyly lagging but sound is playing fine. Any ideas why the video doesn't play properly? It's h.264 mp4 1280x720 and audio is mp3 (i think)
