Topic: The miracle 200 Line Linux Kernel Patch

There's another major breakthrough wink

"The ~200 Line Linux Kernel Patch That Does Wonders" http://www.phoronix.com/scan.php?page=a … &num=1

"It feels as good as Con Kolivas's patches.""

Not long to be able to use it / install it from zen-kernel through smxi?!!

Re: The miracle 200 Line Linux Kernel Patch

Why zen kernel? As soon as it's merged with the mainline kernel, it'll be in unstable soon. Maybe in testing. Patience :-D

#Awebb

Read something about, that the patch would be applied to kernel 2.6.38 - so it would likely be in zen, and liquorix kernel before smile

Ok in this case... why waiting for Zen to do the job instead of applying the patch on your own :-D

Re: The miracle 200 Line Linux Kernel Patch

I am going to try to get this up and running, very interested in kernel patches, and this one seems to be one of the biggest improvements yet! big_smile

Re: The miracle 200 Line Linux Kernel Patch

From what I have been reading, not that I fully understand it yet sad     there is a much simpler way to do the same thing.

Lennart Poettering, a RedHat developer replied to Linus Torvalds on a maling list with an alternative to this patch that does the same thing yet all you have to do is run 2 commands and paste 4 lines in your ~/.bashrc file.

Re: The miracle 200 Line Linux Kernel Patch

Damentz is putting the simpler fix in the Liquorix kernel

That is also why there have been so many updates in the Liquorix kernels lately, bugs found and squished

Re: The miracle 200 Line Linux Kernel Patch

I used the Lennart Poettering method for a couple of days (on LMDE, didn't apply it to my Statler box yet and I'm back on XP for a bit) and from what I could tell is that the most benefit will come from using apps launched from the terminal as also mentioned by ThinkRob in this thread. Doesn't seem like you can reuse the same terminal session, it needs to have it's own tty assignment so you'll want to launch a fresh terminal for each app you want to use it with. So... in my case, I'd have ffmpeg (which is pretty heavy) running from it's own terminal session and then if I wanted to browse at the same time, just launch my browser from a new terminal. CPU usage is still 100% but the allocation seems better for my use (I think you can do similar things with "nice" too, but I haven't used it in a long time).  The assignment sticks for that session, and will remain even when detached via disown (if you don't want extra terms hanging around).

It did seem smoother browsing that way (could be placebo effect) but I won't know for sure until I try it with Statler where I'm used to doing both at the same time. As for general desktop responsiveness, I have no idea. Without playing with this *too* much it seems like it could even be decreased in certain cases since as I recall your desktop handing (including apps launched from the desktop) is folded into in one group, and within that group competes the usual way for current priority. But if this could lead the way for on-demand priority setting at launch through the menus, that could be pretty danged cool.
