RTPL - Realtime Puplet

#1 Post by NeroVance »

As PuppyStudio has a realtime kernel, and 3.3 is derived from Lucid 520, It should hopefully be somewhat easy for me to go and obtain the kernel, and inject it into Lucid 520.

As I am not Barry, I won't call it PuppyRT, I'll refer to it as a puplet, but if Barry or someone else wishes to build a PuppyRT, I'll gladly help out.

If anyone has an idea of what the logo should look like, that would be excellent.

I've got a livecd image built, but it does need a few things, but it is (i believe) bootable, and has a realtime kernel in it.

It however seems to lack networking drivers, hence I'll need to salvage some from PuppyStudio. Anyone have any ideas what programs could be used to help add a priority system to help facilitate control of different applications which don't need hard realtime?

I'll probably upgrade Tcl and Tk to 8.6 since I do tend to work in Tcl, and it would help me out if I have an environment that can handle Tcl/Tk scripts that will hopefully add some capabilities into the OS which could b useful.

I might replace JWM with another window manager, but am unsure about wanting to use IceWM. Perhaps Fluxbox or something else.

If someone actually got WMaker to work on a new puppy, that would be sweet.

you could try using Lucid 5.28. EDIT do network driver have to be compiled against kernel?

You can set the nice of a program when its executed.

For example, if you wanted qjackctl to have a lower nice, change the execute line in its .desktop file-


/usr/share/applications/qjackctl.desktop

Code: Select all

Exec=nice --20 qjackctl

Could be useful indeed. I could probably whip up a Task Manager-like application which can make a friendly GUI for priority setting.

And I do use the Initrd from PuppyStudio (I think).

I am also interested in a RT Kernel for Organ testing.

New to this but have running Puppies working.

Seems a lot of things just seem to DIE.

I have tried Puppy Studio 3.3, jOrganPup and Fatdog 64

I found Precise 5.4.3 to be a good base as Wireless works better than others

Happy to do what I can.

Any good tutorials for not so bright on building puppies.

Have read the Woof page but am still lost.

Here is a bootable (i hope) ISO with a realtime kernel installed.
That is all it has ATM, but I do plan to add stuff for handling priority, and adding a friendly UI to it as well.

Thanks for that will download, try and report-back.

Hope I have some success.

I suppose I need a dev enviroment???

Can I use a rewritable CD and if so how. I have not seen any tutorials on rewritable CD's

unetbootin can turn the .iso into bootable usbstick. Easy!
Boot the usbstick, and in the shutdown process, make a savefile at the prompts, and reboot, and repeatedly resize the savefile
to nearly fill the stick.
(look for that resizing choice in the menu options)

(a few reboots are needed, as resizing occurs on the next boot,
and size constraints are in play. Coffee time, but worth it)

(this is based on other puppies, so ymmv on this release :wink: )

thanks @ciento I have used usb stick

@NeroVance

1. I have tried your iso let me list the problems

all versions of puppy 5.2 I have tried do not work with my wi-fi

puppy 5.4.3 does but claims to use same drivers ???

2. Your iso did not work with my video had to use vesa

Could anyone give me instruction to change my kernel to RTL in 5.4.3

I am not sure at the moment I need an RTL. I do have jOrgan working in 5.4.3

Latency in jack 24ms will RTL improve this I am not running other programs.

Thank you very much for your response :D
I knew that stuff was missing, as the drivers don't appear compatible, hence I wanted to know what problems one faces with the basics of this, that way I can improve it.

I think replacing some modules and drivers with those that the puppy with the RT kernel had should work. This is a prototype afterall :wink:

Why don't you just use Puppy Studio 3.3-rt? It's based on the same version you are trying to switch kernels with, all you're basically trying to do is make a plain version with the apps removed.

@NeroVance

Trying to get into changing modules etc. Not there yet

@Announcer

Puppy Studio 3.3-rt also would not stay connected to wi-fi.
Is it based on lucid 5.2.x?

I think i wiped Puppy Studio 3.3-rt as not working to download java and other programs I needed

Do I need RTK in your opinion?

If all you're doing is using your organ program, then no, you probably don't need an rt kernel.

Yes, 3.3 is based on Lucid 520.

@Announcer

Thanks for your reply

I think I will stick with 5.4.3 then as all is working.
If all works out will probably need new machine with touch screen and decent sound cards

That is indeed the goal. It is just good ol' Puppy (for the most part), but with a realtime kernel, for realtime infrastructure.

That and using it as perhaps my puplet for trying out different things, such as update Tcl to the now stable 8.6, and using a different WM, slim it down, etc.

In truth, I'm not even doing it for musical work :lol:

Hmm.

So, you got an industrial laser kickin' around the house you wanna control, or something?

I'm just bored, and it gives me something to do. Could be useful for communications systems and the like. Even back in the day I always thought I could get puppy to do nearly anything. It is quite the capable distro.
