realtime module?
« on: January 10, 2014, 04:49:12 am »

Hi,
I have installed Vector Light 7.0 with the idea of using it for audio.  It seems quite stable, and even without realtime capabilities it is running Mixbus reasonably well.  But, I would like to experiment with a realtime module if there is still one available.  Apparently there is not one on the system I installed.  Is this module compiled into the Standard VL7 kernel or does the kernel need to be compiled from scratch?  
Thanks!
Grekim

Not sure what you are looking for but ardour and audacity are listed in the package manager for light and gslapt should handle depends...jack is also listed and I think installed with ardour. you would have to build hydrogen but I think there is a slackware package...googled this

http://ftp.arm.slackware.com/slacky/slackware-13.0/multimedia/hydrogen/0.9.4/

you would have to check the depends for that.

hope that helps
cheers

Very possible, I am not sure VL64 or light existed when the thread was created. the realtime-lsm project seems to refer to the 2.6 series kernel, not sure if the project is active or relates to newer kernals. not very helpful sorry.

Are you having issue with applications on VL7.0 light

Vector Linux seems great so far.  I am running the Harrison Mixbus with LinuxDSP plug-ins.  I've only been trying it for a week with these particular programs, but it has been quite stable.   Another shot in the dark is possibly using a Slackware realtime kernel?  I have to assume the Vector kernels and Slackware kernels are not exactly interchangeable?

The bigger question is do you even need it. It may be that you can run the applications fine without stutter or concern.
If you are having issue then it may be worth reverting to an older version...not sure where you would get a dynamite with the realtime-lsm kernal but you can still download the patch from sourceforge and someone could likely help you add it to a vector version using the 2.6 kernel.
Although good to know, if it ain't broke don't fix it.

Usually you do need realtime capabilities for running audio or video production applications, which allows raising the priority for accessing hardware resources to those apps.
The realtime patches for the kernel that we used to use are deprecated I think. Nobody is developing that anymore. I have no idea what replaces that now. If you could find some link to resources we would like to implement what you need for Vector.

Thanks!

My howto is a couple of years old now. I don't know how it's done nowadays, I still use an old vl 5.9 for my music. I'll be keeping an eye on this thread to see what's new...
