hi rockedge, just been running your kernel up the flagpole for a couple of days. Running nicely and low latency in jack/qtractor.
Hard Info/ Available entropy in dev/random=healthy.
A non pae version would be good if you ever feel inclined. Just noticed how pae kernels really use up the ram on little computers.

Hi.

I want to try this by changing the kernels in my Art Studio (tahr602). Do I need to rename the kernel modules sfs to the zdrv sfs?

If not, how to load at boot?

download the kernel
in your installed frugal puppy delete or rename vmlinuz and zdrv_xxx_xxx.sfs Something like vmlinuz-original and zdrv_xxx_xxx.sfs.original

now extract the kernel you downloaded. there are 2 files copy those into your frugal install and rename them to match the vmlinuz and zdrv_xxx_xxx.sfs you deleted or renamed

reboot.

that is all there is to it. and for you I would try the full rt version...I have been using LMMS to test and so far good results. on Tahr, Xenial and Bionic all 3 just built using woof-CE

I changed to this kernel in XenialPup 7.5. It works quite well on my rig.

Thanks for making that available. I tried it on my little netbook, but it took a lot of ram up. Is it definitely no-pae?
When I boot up with a pae kernel, the ram container on the desktop is always kind of half empty, but say with Joseph's pupjibaro (non pae) 3.17xx it is full.

Thank you Rockedge for this updated Tahr with a newer kernel runs sweetly on my Dell D620. Very Happy

Smithy, I double checked and the kernel is definitely no-pae

I will test to see what the RAM usage looks like on my IBM ThinkPad T-42 using this tahr and kernel combo....

What is the difference in a RT kernel and a normal kernel?

Does the RT kernel give you something you need?
Some added features?

a very general rule of thumb

Thanks Rockedge, I was running it in Artful, possibly I need to tweak the initrd.gz or something. I made an only i915 barebones Artful for my netbook, but the pae's are not very good with it.

Hi.

I'm using the real time kernel now for a few days and it seems to be pretty stable.

Though, the problem I was hoping to solve by the use of a real time kernel still remains. Getting Xrun some frames might be lost messages still in Qtractor. I'm using it in combination with Hydrogen and ZynAddSubFx. The Xrun some frames might be lost messages appearing only on the ZynAddSubFx tracks and they disappear when muting single tracks (which couldn't be of any solution). Confused
